Supply of cement septic tank manufacturer - Mai Ding Cement Co., Ltd.

Septic is processed and filtered fecal sedimentation equipment. The principle is to prevent the decomposition of solids at the bottom, the upper body hydration, go into the pipeline flow to prevent clogging pipes, to solidify the object (manure and other waste) have sufficient time to decompose. Septic refers to the sub-grid sewage sedimentation and sludge anaerobic digestion of small treatment structures. Septic Septic chemistry is a use of the principle of sedimentation and anaerobic fermentation, removal of suspended organic matter in sewage treatment equipment, are the primary transitional living treatment structures. Sewage contains large amounts of manure, paper, protozoon, suspended solids concentration of 100 ~ 350mg / L, concentration of organic matter B0D5 between 100 ~ 400mg / L, wherein the concentration of suspended organics B0D5 of 50 ~ 200mg / L . Sewage into the septic tank by precipitation into 12 ~ 24h, and can remove 50% to 60% of the suspended solids. Sludge settling down after three months or more anaerobic digestion of organic matter in the sludge into stable inorganic, perishable sewage sludge into stable cooked, changing the structure of the sludge, reducing pollution soil moisture content. Sinotrans Qingtao regular sludge, landfill or used as fertilizer. Calculating the volume of precipitation require septic tank section and corruption section, should be "building water supply and drainage design specifications" (GB50015-2003) Section 14 OK. Stay in the septic tank effluent in time should not be less than 36h, no sludge disposal for the sewage system, septic tank sludge volume should also include storage volume. Qingtao septic tanks and waste water and temperature cycle, temperature, nature of buildings and drainage water quality, water related. Qingtao design cycle is too short, the high concentration of septic tanks, liquid manure, and the actual Qingtao cycle gap is too large, affecting the normal fermentation and wastewater treatment effect, or even result in overflowing liquid manure, affecting the environment and health. Qingtao design cycle is too long, the septic tank volume is too large, increasing the cost. "Construction of water supply and drainage design specifications" (GBJ15-88) (hereinafter referred to as "Code") requires Qingtao period of 3 to 12 months, more than the actual design to take 3 to 9 months, and acid fermentation of acid fermentation stage is 3 months, acidic loss of five months or so. Proved: Qingtao take definite period, should take into account the effect of sewage treatment, construction cost, three factors Qingtao cycle management in general should not be less than 12 months. Spring water dormitory door cottage group shared septic tanks, use the number 200, sewage standard 30L / d, the amount of sludge per person 0.4L / d per person to enter the septic tank sludge moisture content fresh take 90% Design Qingtao 12 month period selected by the computing capacity of the septic tank 21m3. Septic residence time residence time is an important indicator of the relationship and septic tanks and sewage treatment effect of volume and cost, among too short, the sewage poor treatment effect; when the residence period of time, but also increase the volume of the cost of a septic tank, and layout difficulties. Determine the residence time, should take into account the factors that effect the cost of construction of sewage treatment, taking into account both the impact of bubbles produced by fermentation of laminar flow requirements of precipitation, septic tank flow lines turning more adverse effects on precipitation, sewage discharge hatch changes even bigger impact on the amount of water, septic tank should leave room residence time. "Standard" requirement: residence time to take 12 to 24 hours. Proved: dwell time should not be less than 2d hours to ensure water sewage treatment effect Lantern door septic quarters residence time of 24 hours. 1. With the development trend of economic development, the country should speed up the construction of urban sewage treatment works, and gradually, as soon as possible to replace septic tanks, sewage treatment to improve the standard of living, to ensure that the sewage treatment effect, to protect the environment, reduce pollution, but also solve Septic environmental health problems. 2. Can the traditional septic tank converted into biogas, this topic is central AiWeiHui promote the project. National patent and China, "Edison Cup Award" Jinhua "ecological toilets" that are successful examples of biogas purification tank located under toilets, fecal sewage digesters treatment by the abolition of the septic tank, biogas produced for the management of public toilets who do live fuel waste as toilet roof, walls, green environment around and vegetables organic fertilizer, manure treatment has the effect, the comprehensive utilization of waste, easy to use, beautiful environment, economic interests, environmental and social benefits significantly and other advantages. 3. In recent years, the country began to study the transformation of the traditional five grid septic tank anaerobic digester is a broad prospect for development direction. Foreign current use of small anaerobic or aerobic sewage purification tank is also worth studying. 4. Septic as a transitional form of long-term existence, we must vigorously strengthen the management of septic tanks, strict implementation of regular Qingtao system, according to Taiyuan three residential investigation, not more than two years accounted Qingtao septic tank 80% of the total, and some have never been used since the first dig too. 5. In the septic tank management, you can use bleach * mandatory regular disinfection, to enhance treatment results in improving the bacteriological indicators of water, but not too often because of normal use bleach * fermentation. Product advantages combined with reinforced concrete septic eight major advantage 1. Green: sewage treatment level is higher than the national standard, mxn purification. 2. Energy saving: the use of force even without a new structure, widely used, the country. 3 save money: the introduction of new product ideas and technology building, prefabrication, site assembly, saving developers money. 4. Any combination of: available scattered, irregular plots. 5. Improve the sewage treatment effect: the first generation of brick septic tanks, septic tanks second of concreting belong rectangular pool. Co-existence of sewage dead, and I produced a square septic tanks, is not dead, according to conservative calculations, can be set up to improve the efficiency of 12% water. 6. tightness, good stability: the use of bump slot interface connection, tightness and stability greatly. 7. The construction period is short: the use of on-site septic masonry, usually for 3 weeks to five weeks, our products assembled only 3 to 4 hours. 8. replacement, it is imperative: I introduced special services products, the Patent Office of China's construction industry, once hailed as innovative, the product quickly in Beijing, Tianjin, Shenyang, Harbin, Changchun, Baoding, Shijiazhuang, Changsha, Xinjiang universal application of large cities. The advantage fiberglass septic tanks are as follows: 1. Material strength: big member thickness, high material strength (c30) concrete and buried anywhere Over time, continued to increase the intensity. 2. large capacity can be arranged at carriageways: single span roof tank is small, small thickness, reinforcement large (diameter of 12mm headphone rolled ribbed steel bars), the annular side wall of the tank force, such as a large area of ??uniform Therefore high bearing capacity. 3. The duration and cost savings is shallow,: due to material properties and build good character, it can be buried under the road traffic, and the depth is shallower than fiberglass septic tanks, duration and cost savings (such as the amount of excavation and water wells height reduction) 4. accommodate narrow or complex plots, small footprint: a single tank bottom area for a relatively small cube rules, and can be freely combined in any order, can be adapted with narrow or complex plots, accounting land area is small. 5. save money: the introduction of new product ideas and technology building, prefabrication, site portfolio, saving developers money. 6. backfill soil is less demanding: due to high material and structure strength, hardness strong, so do not ask for backfill soil, thus saving cost and schedule. 7. The ability to resist impact and backfill strong lateral pressure: external double reinforced, so strong ability to resist impact and side backfill pressure. 8. backfill to the pool without water: To prevent the squeeze in the process of filling the role of Turkey in the side of the pressure along the side wall of the arc and bedding planes, lift off the mat, so fiberglass septic tanks need before backfilling The amount of water injected into the pool to make the body stable cell body; and precast concrete septic tanks Combined weight, high strength, and the vertical sidewalls close contact with the cushion, when the need to backfill the pool water, reducing duration, cost saving and water resources. The advantage site pouring concrete septic tanks are as follows 1. The construction convenient, time is short: only 3-5 hours to complete the assembly and start backfilling. 2. Can be adapted to a narrow or complex plots, small footprint: and can be combined, in any order, can be adapted to a narrow or complex plots; small footprint. 3. The need to design a septic tank construction plans, saving time, saving design fees: According to the design capacity of the liberal changes in combination, no septic tank design and construction plans, saving time, saving design fees. 4. large carrying capacity: high strength concrete (C30), single-span roof tank is small, the thickness of the large (200cm), reinforcement large (12cm in diameter for the two hot-rolled ribbed steel bars), a large tank annular side wall area even by force, etc., so high bearing capacity. Resistance to impact and side backfill strong pressure: external double reinforcement, so strong ability to resist impact and side backfill pressure. 5. The overall placement of the bottom wall between the annular sections "concave", "convex" slurry tank sit and do bite flexible waterproof design, better anti-leakage effect: the seam for a ring "concave", "convex" slurry tank sat glued design and flexible waterproof splice sites do, avoid the cast pits in the general construction joints leaky quality problems. 6. clogging smooth wall; wall smooth easy clean up dirt poor adhesion: the whole plant delicate slip cast precast mold fine, smooth wall clogging and dirt especially poor adhesion, easy clean-up.
