Abstract

The invention provides a sewage treatment system. The sewage treatment system comprises a filter tank, a first filter plate and a treatment box, wherein an opening formed in the top of the filter tankis covered with the first filter plate, and multiple first filter holes are formed in the first filter plate; a first drain outlet is formed in the side wall of the filter tank and communicated withthe treatment box through a first guide pipe; a discharge outlet is formed in the bottom of the filter tank, and a blow-down valve is arranged on the outer side of the discharge outlet. Therefore, when sewage enters the filter tank through the opening, garbage in the sewage can be blocked at the upper part of the first filter plate, separation of the sewage and the garbage is realized without artificial fishing, and the operation is simple and labor-saving.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment manufacturing, in particular to a sewage treatment system. Background technique [0002] With the increase of urban population density, the discharge of sewage is increasing year by year. Since the sewage contains heavy metal ions, directly discharging the sewage into the environment will cause environmental pollution; therefore, how to treat the sewage to reduce the amount of sewage in the sewage The content of heavy metal ions, and then meet the emission standards has become a research hotspot. [0003] In the prior art, the sewage is transported to the sewage treatment tank through the pipeline, and then the workers use the hand-held salvage net to salvage the large insoluble garbage in the sewage treatment tank to prevent the garbage from affecting the subsequent sewage treatment. The salvage net includes: a net bag and a net rod connected to the net bag at one end,...
