Owen purifier with you and see how the ancient Chinese protection of drinking water sources

The quality of drinking water quality in relation to people's health and life safety, for the protection of drinking water sources, the ancient Chinese from the water supply, water purification has a set of methods to protect the water, even when the Yuan Dynasty in for hand washing in the canal will be severely punished. Ancient how to ensure drinking water? Spring and Autumn Period, "Zhu Yi well, so go hereby poisonous" China's first drinking water source protection acts, should come in well water protection. Well, the most important of the ancients drinking water facilities. Legend of the Five Emperors Zhuanxu well is the offspring of the first Emperor Ying Zheng Zu Boyi invention, "Lu" in the so-called "Boyi as well", he said the situation is all about. From the point of view of modern archaeological discoveries in ancient Shang and Zhou period, and use of wells drilled has been popular in Henan Yanshi and Zhengzhou Mall site ruins are found Doi this period. In fact, in the earlier primitive society, the ancient Chinese have used well, and in Yuyao, Zhejiang Hemudu site, they found a well. To the Warring States period, the wells have been very popular. As in the southwest of Beijing, this ancient capital of Yan Ji City Ruins, 1956 with the archaeological excavations in the Yongding River diversion project, the 151 has been found from the Spring and Autumn and Warring States Period to Han and other wells. As an important source of drinking water, the ancient Chinese people special attention to protecting water, well water and even become a code of ethics to protect the ancient citizens. Ancient Chinese divination deduction for the originator of the "Book of Changes" "hexagram", Section 48 Gua, Guaming is "well", which reflects the importance of the well in the human life, will be revealed in Gua speech When a man is how to protect wells and well water. Mainly adopt three kinds of means to a "get rid of." Han Xun Shuang think, is to get rid of dirty cleaning meaning, similar to the later of Amoy well, periodically clear the mud, so clean well water. This practice later became a kind of folk, Spring and Autumn Period Amoy well once each spring, "Pipe Chapters · ban possession" describes the situation: "When the spring in March ...... Zhu Yi well, so go hereby poisonous. "probably means is that every spring in March Amoy well change the water, the water to eliminate pathogenic substances. To the Han Dynasty, wells cleaning is scheduled during the summer peak water comes the summer solstice, "Han Chi etiquette (in)" records, "is the day Chun well water improvement" improve water quality in order to reduce the consumption of contaminated well water and caused direct seasonal disease. Two "Zhou." Yu Fan interpretation of the Three Kingdoms, "In tile glazed tile tired well, Zhou said," is to improve the well-made craft, reinforced with ceramic tile wall, to prevent and reduce soil scattered wells, the wells purpose other than to extend the service life, but also intended to well water cleaning. Three "screen." This method is well and lid to prevent dirt falling into miscellaneous, pollute the water, bright scientist Xu Guangqi "agricultural policy book," said the "anti-power consumption, but also anti-dirty, ancient well and therefore, power." To the Northern Song Dynasty more attention this one, then the capital of Tokyo (now Kaifeng) Street wells are fenced, cover, pay attention to a little above build a shed, covers locked to prevent rats, bugs and naughty child to fall littering the well, the well water get dirty. How ancient drink "pure water"? Ming Dynasty "boat people to clarify the law, and willing to drink it." Water in nature, it is inevitable contamination. Ancient Chinese people have long realized this, strengthening water conservation, but also to discover and find a lot of water disinfection, more sanitary way to make drinking water, drink "pure water." Well water can be divided into three rank or grade, Ming Li's "Compendium of Materia Medica Water", "Jing Quan water" has this view: "Where the water, there is a far from terra comer" Ming Xu second bail "Tea Shu." said, "The ancients product water, Jinshan in Ling as the first spring", this water is actually spring from the Land of the distant past, was viewed as the best water for tea. Near the rivers and lakes of well water infiltration to those who followed, as the city near the sewage ditch, sewer water, the worst water quality, it can not be directly consumed, "the smell of all evil, unbearable medicine, food, tea, wine." Poor water quality well water, the easiest way is to boil the water, after the cold will clear impurities sink down. Boil water to drink pure water ancients easiest and cheapest way, which people today seem too juvenile, the ancients but after a long practice, only to find and establish it. If large quantities of water, "cooking method" is obviously unable to meet the need, but also a waste of firewood fuel, increasing the cost. How do? We all know that most of the Yellow River water impurities, very muddy, but the Yellow River boatman there is a way to make the Yellow River water becomes turbid as clean as spring, sweet, namely "Tea Shu" recorded "boat people in order to clarify the law drink and Gan. "Yellow River boatman in the end of the Ming Dynasty with what magic bullet, Hsu Shu times in the book did not explain. Scholars speculate that perhaps the late Ming Fang Yizhi method in the "Physical little knowledge" and reads: "The unusual given water, alum, red bean, almond, realgar, plaster Jieke." The so-called "fixed water", is the production of pure water, clean water programs. Modern water studies have confirmed that the ancient Chinese people discovered the Clean Water Act, a lot of very science. Such as alum, which contains colloidal aluminum hydroxide has a strong adsorption capacity, can absorb water and suspended impurities, and the formation of precipitation, the water clarification, is a good purifying agent. Ancient drinking water source protection law? Yuan for bathing "hold and bamboo cane of" To ensure the water supply, the ancient city also attach importance to the planning and construction of water supply facilities in the drains. 1977 began to explore the Eastern Zhou Yangcheng ruins, they found not backward in today's urban water supply facilities: Water supply ceramic pipes Buried in the ground, with a clear pool, the valve pit. Cheng pond called "Cheng slot", is the modern water sedimentation pond, clear water through the settling tank, after clarification, then access into the city for residents. Some of the royal dynasty also set up special water, do special for. Such as the Yuan Dynasty, specialized dig Jinshuihe, pooling water Yuquan Shan Zhu Quan, the from and to the gates of righteousness (now Xizhimen) Nanshui door introduction of the city, passing through palace, inject too liquid pool, drinking water sources and make Imperial palace water. Construction of water facilities, is to improve the supply of drinking water from the hardware and the protection of ancient as well as from the "software" in management. Dynasties have set up a special "water officer", responsible for water resources, water safety, Han Dynasty, "water-Shing," the Western Jin Dynasty, "all the water table", "all water prison" after Sui and Tang dynasties, to ensure urban water supply, but also their points One area of ??responsibility. To protect drinking water sources, the ancient but also introduced the corresponding rules and regulations, uncivilized punish immoral behavior, which is today called "legislative protection." Such as the Southern Song capital Lin'an (now Hangzhou), Zhao Shen (Song Xiao Zhong) When the trunk between the emperor, the city's largest water source Lake by man-made pollution threat, people have poured into the lake feces, garbage bad habits, Zhou Cong played intrinsic appease Song Xiao Zhong decree "prohibits officials and the public abandoned dirt, planting lotus Ling and other objects in the lake, and offenders punished." interior minister 刘敏贤, Liu fair occupy the lake, Seba wash dirty, contaminated water, has been reported for impeachment were dismissed. One of the most important reasons for its official strike is "to generate a city of Li Yuan, drinking dirty and greasy Cho-sky catastrophe diseases." Yuan Dynasty, the Royal Jinshuihe drinking water coming through, but despite Majesty special water channel, but the water was also threatened by man-made pollution, the summer that someone jumped into the river to take a bath, Seba, dirty water. To rule two years (1322) in May, Yuan Hidemune for Jinshuihe pollution problems, make special instructions (Chile), according to the "Yuan Shi Chi canals" (Juan Liu xiv) records, when the dollar Hidemune this to say: "When in the past ancestor, Jinshuihe wash hands and prohibitions, this is Seba those who have, sparse than to wash, cut Morohito Wude filthy." "All water monitoring Chronicle," said it more clearly: "Goldwater into Ouchi, who dare to have a bath, Huan Yi who spoil stone Ling caldron which drive cattle to drink who are executing and flogging it." Yuan this provision, it is legislative acts can be seen as ancient protect drinking water sources in the Jinshuihe, not to mention take a bath, wash your hands even such small things are strictly prohibited, if it is found will all be arrested, sentenced to flogging. In addition to the court ban, there have been local ancient water protection legislation. During the Qing Dynasty, Suzhou there such a provision in the Yangtze River Delta, near Suzhou Tiger Qianlong throughout the dye, industrial waste straight into the river, leading to "full river green purple red and black" can not drink the water, aroused public indignation. Qianlong years (AD 1737) local ban and stone stand next to the river, this is the "Suzhou government set up permanent ban Tiger dye polluted river monument" in origin. Inscription expressly provides that "dyed as artifacts, migrate elsewhere opened", "as dare violate it, given row mention study." Underground water quality ancient than modern okay? Yuan Beijing "bitter salty water rate" Recently Beijing's drinking water quality leads to storm Readers may think that groundwater quality should be better than the ancient and modern. In fact not the case, from the Han and Tang to the Qing, Beijing has been the case from time to time deterioration of groundwater quality, sometimes even simply can not drink. Beijing residents over the main drinking water, inside Beijing hutongs have dug wells Yuan Dynasty, when the Qing Dynasty as well. According to the Qing Zhu, a new "Capital Square Lane Chi draft" in the statistics, more than half of Beijing Hutong chisel wells, of which there are 701 in the city, outside the city 557. While much wells, but few good water quality wells. Yuan Wang Yun "Qiu Jian set" has this text:. "Bitter salty water rate, well derived Schoenbrunn who number one hundred twelve" has been to the Qing Dynasty, Beijing seems to have not changed underground water quality is good, clean Anonymous "Yan Beijing Notes "said," the capital of the water, the most unpalatable bitter solid not drink. "Because the poor quality of underground water from the well water can only be used to play up to the laundry shed. Beijing was conditional to the people and the modern supermarket to buy bottled water, as Beijingers was also scrambling to buy tankers shipped from outside the city to sell the "sweet water" for drinking and tea. When the Qing Dynasty, then moved to Beijing to talk about, you can see "the capital of each lane, there is Ji who sell cars aqueous phase." Because many people buy water, price is not cheap, selling water business is booming in the capital, water vendors also easily raise prices. Moreover, the ancient underground water quality deterioration, is not unique to the city of Beijing, a number of cities Chang'an City, the city of Kaifeng, also have this phenomenon occurred repeatedly. As in shallow groundwater quality Suichu Han Dynasty serious deterioration of the old city of Chang'an, salty and bitter, not drinkable, which is the Emperor Wen Yang Jian choose another site set up one of the reasons of the Daxing District. Yang Jian dug a canal dragon head, Wing drainage, drains Qingming three waterways, the Chang'an New City water supply. When the late Tang, which was severely damaged water supply facilities, public wells had to rely on groundwater. To Zhao Heng (Zhenzong) when the emperor Dazhong Xiangfu seven years (AD 1014), bitter salty well water, bear edible. As was the important "projects that benefit the official restoration of the Tang Dynasty dragon head Oxbow West Drainage Canal, has been used in the Jin Dynasty. To the late Yuan Dynasty, Chang'an City drinking water has become a problem, further deterioration of groundwater quality, to the Ming Dynasty Water quality has deteriorated to the extreme. According to the "History of the Ming Chi canals six" record, Hongwu years (AD 1379), the emperor nephew Li Wenzhong and Tao Xiping Houmu Ying soldiers into the state (now Gansu Lintan East), after Chang found that the city bitter and salty well water, do not drink, they'll drink to consult the emperor, the introduction of the first Dragon Ditch digging Shiqu, this improves the quality editor:..
