Treatment device for sewage

Abstract

The invention discloses a treatment device for sewage. The device comprises a filter box, a water inlet pipe is fixedly installed at the left upper part of the exterior of the filter box, a filter netis movably installed in the water inlet pipe, the right side of the water inlet pipe is fixedly connected with a mobile power source, a stirring device is fixedly installed in the middle of the upperpart of the inner cavity of the filter box, a harmful-substance absorbing net is fixedly installed below a large-particle substance filter net, and a small-molecular substance filter net is fixedly installed below the harmful-substance absorbing net, a clean-flow pipe is fixedly connected with the lower part of the right side of the exterior of the filter box, a polluted-flow pipe is fixedly connected with the middle of the bottom of the exterior of the filter box, the polluted-flow pipe controls a water flow through a polluted-flow pipe valve installed on the polluted-flow pipe, and four disc-type supporting legs are fixedly installed at the bottom of the filter box. The device provided by the invention is simple in structure and convenient for invention, after the sewage is treated, multiple filtration of the sewage can be realized, and harmful substances and small molecular substances can be effectively filtered out.

Description

technical field [0001] The invention relates to the technical field of sewage filtration, in particular to a sewage treatment device. Background technique [0002] Surface water pollution is obvious, but groundwater pollution is shocking. Among China's 1.3 billion population, 70% drink groundwater, and more than 400 of the more than 660 cities use groundwater as their drinking water source. However, according to reports, 90% of the country's urban groundwater has been polluted. Another set of data also shows that groundwater is facing severe challenges. In 2011, 9 provinces and municipalities including Beijing and Shanghai evaluated 857 monitoring wells within their jurisdictions. The water quality of the monitoring wells was Class I and Class II, accounting for 2%, while the monitoring wells of Class IV and V were as many as 76.8% . The increasing water pollution situation has brought unprecedented attention to the sewage treatment and recycling industry. However, the ...
