Hohhot septic tank function and working principle
With the development of the economy, environmental protection issues are being addressed. It is a kind of low-level transitional subsistence treatment structure, which is a treatment measure to remove suspended organic matter in subsistence sewage by using the principle of precipitation and anaerobic fermentation. 清理，玻璃钢化粪池，化粪池结构， 尺度图集。 Septic tank size, cleaning, glass reinforced septic tank, septic tank structure, scale atlas. Localities should speed up urban sewage treatment, gradually and quickly replace septic tanks, improve the degree of subsistence sewage treatment, ensure the effect of sewage treatment, protect the environment, reduce water pollution, and solve the environmental sanitation problems of septic tanks. Septic tanks are divided into brick septic tanks and glass reinforced septic tanks.
The sludge is cleared out for transportation, landfilled or used as fertilizer. After the sewage enters the septic tank for 12 to 24 hours, 50% to 60% of suspended matter can be removed. Subsistence sewage contains a large amount of feces, paper scraps, and pathogens. The suspended solids concentration is 100 ~ 350mg / L, and the organic matter concentration BOD5 is between 100 ~ 400mg / L. The suspended organic matter concentration BOD5 is 50 ~ 200mg / L. The settled sludge is digested by anaerobic for more than 3 months. Hohh septic tank decomposes the organic matter in the sludge into unorganized inorganic matter. The structure of the sludge is reduced, and the moisture content of the sludge is reduced.
