A dual-pulse sewage treatment system

Abstract

The invention discloses a double-phase sewage treatment system comprising a 1# reservoir, a 1# lift pump, an anaerobic pulse reaction tank, a 2# reservoir, a 2# lift pump and an aerobic pulse reaction tank, wherein the 1# reservoir is connected with the anaerobic pulse reaction tank by virtue of the 1# lift pump, the anaerobic pulse reaction tank is connected with the 2# reservoir, and the 2# reservoir is connected with the aerobic pulse reaction tank by virtue of the 2# lift pump. The double-pulse sewage treatment system disclosed by the invention is compact in structure, small in floor area, high in oxygen utilization efficiency and high in pollutant removal rate, also has a relatively good treatment effect on livestock and poultry breeding sewage with relatively high influent concentration, improves the utilization rate of oxygen in sewage treatment, effectively reduces the running cost of sewage treatment equipment, and can be applied to treatment of municipal sewage, rural centralized domestic sewage, livestock and poultry breeding waste water and industrial waste water.

Description

Technical field [0001] The invention relates to a high-efficiency and energy-saving sewage treatment system, and more specifically to a dual-pulse sewage treatment system. Background technique [0002] At present, in the sewage treatment industry, a combination of anaerobic, aerobic and advanced treatment is generally required to achieve the discharge of sewage; the treatment process is complicated, the area is large, and the infrastructure and operating costs are high. [0003] For aerobic processes, aeration is now generally used to achieve an aerobic environment in the sewage treatment system. In the traditional aeration system, the oxygen utilization rate of perforated aeration is less than 7%, while the oxygen utilization rate of microporous aeration is only between 20% and 30%, which causes serious energy waste. [0004] In order to make the sewage treatment reach the standard, the advanced treatment process generally adopts ecological engineering such as artificial wetland an...

Problems solved by technology

In the traditional aeration system, the oxygen utilization rate of perforated aeration is less than 7%, while the oxygen utilization rate of microporous aeration is only between 20% and 30%, resulting in serious energy waste

[0004] The advanced treatment process added to meet the sewage treatment standard generally adopts ecological projects such as artificial wetlands and oxidation ponds. These technologies generally have the problem of poor operation effect when the temperature is low in winter
