Low energy consumption sewage treatment system based on energy conservation and environmental protection
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a low-energy-consumption sewage treatment system based on energy conservation and environmental protection.
Background
With the development of economy and the advance of urbanization, the discharge amount of industrial sewage and domestic sewage is increased year by year, and enterprises around rivers in the general cities are numerous and have heavy pollution industrial distribution such as leather factories, waste engine oil processing factories, electroplating factories and the like, and the enterprises are basically heavy pollution enterprises such as leather wastewater which has the characteristics of large water quality and water quantity fluctuation, high suspended matter concentration, easy decay and large pollution amount, and the wastewater contains toxic compounds such as nitrogen, phosphorus, sulfide, cadmium and the like. The oil leakage of the waste engine oil factory causes serious pollution to the water body, basically every 1L of engine oil can pollute the water body with the area of 100000 square meters, the closed oxygen deficiency of the water body is caused, and the natural degradation period of the oil is very long; the electroplating wastewater not only has acid-base change, but also can contain pollution such as cyanide, ammonia water, salicylic acid, heavy metal and the like when the electroplating wastewater is not completely treated. The pollution of ammonia nitrogen, sulfide, heavy metal and the like can directly pollute the water body, and the ecological balance of the water body is fundamentally destroyed because many pollutants have biological toxicity. And the domestic sewage of the residents nearby can not reach the position of the comprehensive domestic sewage pipe network, so that the domestic pollution can be discharged into the inland river channel, and the self-purification capability of the water body is seriously influenced.
In a sewage treatment system, sewage is subjected to treatment and processing such as multiple times of filtration, wherein the initial filtration is generally to remove solid particles and other dirt in the sewage through a filter screen, but the filter screen needs to be cleaned or replaced frequently, so that the energy consumption of equipment is very high, the workload of workers is increased, the filter screen cannot be ensured to be in a clean state for a long time, and the subsequent sewage treatment effect is influenced.
