Problems solved by technology

[0002] In the aeration tank of the ordinary activated sludge method, only aerobic biological treatment can be carried out, and the sludge flowing into the sedimentation tank gradually increases, and it must be manually extracted for future use, while the aerobic zone (aeration tank) and anaerobic zone ( Sedimentation tank) is separated, the sludge cannot automatically return, let alone automatically circulate in the aerobic and anaerobic areas (removal of nitrogen and phosphorus)

Abstract

The invention discloses a domestic sewage treatment apparatus through negative pressure diversion. The apparatus comprises a reaction tank. A negative pressure diversion plate set is installed inside the reaction tank. The reaction tank is divided into an aeration area and a depression area by the negative pressure diversion plate set. The aeration area is connected to the depression area with a connecting pipe across through the negative pressure diversion plate set. An aerator is installed at the lower part of the aeration area, which is close to the negative pressure diversion plate set. A mud pump is installed at the lower part of the depression area. An overflow outlet is installed at the upper end of the depression area. The negative pressure diversion plate set consists of three diversion plates. The apparatus is free of the secondary sedimentation tank and saves land occupation by integrating the aeration area and the depression area; and the investment is saved by saving the land occupation, and the input of structures and equipments.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a negative pressure diversion domestic sewage treatment device. Background technique [0002] In the aeration tank of the ordinary activated sludge method, only aerobic biological treatment can be carried out, and the sludge flowing into the sedimentation tank gradually increases, and it must be manually extracted for future use, while the aerobic zone (aeration tank) and anaerobic zone ( Sedimentation tank) is separated, and the sludge cannot automatically return, let alone automatically circulate in the aerobic and anaerobic zones (removal of nitrogen and phosphorus). Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the above defects and provide a negative pressure diversion domestic sewage treatment device. [0004] Technical solution: The technical solution of the present invention is a negative pressure diversion dome...
