Sewage collection device, sewage treatment system and sewage treatment method

Abstract

The invention discloses a sewage collection device, a sewage treatment system and a sewage treatment method. The sewage collection device comprises a first sewage branch pipe communicated with a user drainage system; a solid-liquid separation device communicated with an output end of the sewage branch pipe, wherein the solid-liquid separation device comprises a tank body and a lifting basket grid arranged in the tank body, the first sewage branch pipe is communicated with the internal portion of the lifting basket grid, a second sewage branch pipe is communicated with a non-grid area and the non-grid area is an area located outside the lifting basket grid and inside the tank body; the second sewage branch pipe communicated with a liquid output end of the solid-liquid separation device; a sewage main pipe communicated with a sewage treatment device, wherein an output end of the second sewage branch pipe is communicated with the sewage main pipe. The sewage collection device provided by the invention improves the use safety and the sewage treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage collection device, a sewage treatment system and a sewage treatment method thereof. Background technique [0002] In order to avoid environmental pollution, sewage needs to be treated before being discharged. At present, there are serious problems in sewage treatment in our country, especially rural sewage. [0003] At present, the domestic sewage of each farmer will be treated in an anaerobic digester before entering the main sewage pipe. Due to the lack of operation and management technology for anaerobic digesters (such as septic tanks) in rural areas, the possibility of biogas explosion has increased, which has brought huge hidden dangers to farmers' lives and properties. Moreover, the reaction time of anaerobic digestion is long, and the sewage needs to stay in the anaerobic digestion tank for a long time, which affects the efficiency of sewage ...
