Abstract

The invention discloses a secondary sewage treatment tank with a backwashing device. The secondary sewage treatment tank comprises a primary sewage tank and a secondary sewage tank. A filter pipe is connected between tank bodies on the lower sides of the primary sewage tank and the secondary sewage tank, and a filter is disposed in the filter pipe. A front end orifice and a rear end orifice of thefilter pipe are respectively provided with a first three-way valve and a second three-way valve. One end of the first three-way valve is communicated to the filter pipe, and the other end is communicated to an opening of the primary sewage tank through a water distribution pipe. One end of the second three-way valve is communicated to the filter pipe, the other end is communicated to an opening of a backwashing pump, and the other end of the backwashing pump is connected to the pipe body between the filter and the second three-way valve through a connecting pipe. The secondary sewage treatment tank with the backwashing device is simple in overall structure, easy to install and manufacture, convenient to operate and capable of effectively achieving the backwashing process of the filter inthe filter pipe, improves the filtering effect of the filter, saves manual maintenance strength and achieves high practicability.

Description

Technical field: [0001] The invention relates to a secondary sewage treatment tank with a backwashing device, and relates to the technical field of sewage treatment. Background technique: [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse.
