 BestBath about the speed of urbanization in driving economic and social development of the rapid urban water environment has brought serious damage to the growing contradiction between water supply and demand intensified. Water pollution can be divided into two categories: point source pollution and non-point source pollution. Non-point source pollution is mainly non-point source pollution in Henan metal surface cleaning company recommended means lower pollutants in precipitation runoff and erosion atmospheric leaching effect in the form of wide-area distributed into the water pollution caused by the receiving water body. PRAKASH such as the use of remote sensing and GIS technology to build models Henan someone metal surface cleaning service is better, find suburban residential area is the strongest source of nitrate contamination. Nitrogen and phosphorus load of non-point source of Jinjiang River found: Non-point source nitrogen load of 12 298.95t / a, mainly from livestock, agricultural runoff and sewage in rural areas, the contribution rates were 31.72%, 26. 38% and 17.44%; non-point source phosphorus load 667.04t / a, mainly from soil erosion, agricultural runoff and sewage in rural areas, the contribution rate of 43.27%, respectively, 21.10% and 12.25 %. In recent years, huge investment in environmental protection in urban areas, and constantly improve the pipe network, sewage treatment plants and the construction of a large number of relevant laws and regulations and implement the gradual improvement of urban water pollution control has achieved some results, but the black-odor river regulation, landscape restoration and other still water the more developed eastern city of urgent problems, and distributed point source sewage is an important source of contamination. Compared to a centralized point source pollution, point source pollution is a much more complex and difficult problem. Urban non-point source sewage mainly suburban areas and rural zones upstream disorderly discharge sewage, taking into account the relative dispersion of the population living in these areas, pipeline construction investment, the use of centralized sewage treatment plant efficiency is not high. Therefore, to explore the economic, effective decentralized sewage treatment method has become one of the key restoration and maintenance of urban water environment. BestBath about our main source pollution Early on Dianchi, Taihu exploratory research. In recent years, many experts and scholars from the introduction of foreign technology purification tank, FILTER technology, artificial wetlands and other technologies to explore and try a multi-party. However, at present most of our suburban and rural areas better yet decentralized sewage treatment facilities, even more economically developed coastal suburban and rural areas, home sewage discharge is generally only after simple treatment of septic tanks, and septic pool can not effectively remove contaminants metal surface cleaning, plus the underlying surface is covered with more and more concrete, asphalt and other pollutants infiltration limited more by the confluence of pollutants into the river or reservoir near the basin. In a decentralized non-point source sewage disposal Henan metal surface cleaning what the company is better, Jiangyin City, Jiangsu Province, walking in the forefront of the country, established in November 2009 to take over and can not be reserved for residential planning sewage, high-efficiency, low consumption, economic and simple to maintain wastewater treatment technology. China's urban and rural economic level less than Western countries, differences in lifestyle caused by sewage composition differences, while protecting and restrictions on foreign ownership of the technology, making the country can not directly use foreign technology to solve existing domestic point source sewage treatment problems. For now, the local conditions of decentralized ecological wastewater treatment method treatment effect is stable, less investment, simple management, etc., not only for our current circumstances, and in accordance with ecological, sustainable development trend, gaining more and more experts recognized scholars, is considered to be a very promising approach.
