Abstract
The present disclosure of a sewage treatment device includes a compression tank that is cylinderically shaped, a stirring structure communicated with the compression tank by a first intermediate pipe, and a detection box communicated with the stirring structure by a second intermediate pipe. A telescopic driving cylinder is arranged on an upper portion of the compression tank and a conveying pipe is connected to a top surface of the compression tank to deliver external sewage to an interior of the compression tank. A diameter of the conveying pipe ranges from 8-15 cm; A filter interlayer is arranged in an interior of the compression tank and the filter interlayer is annular. An end of a driving shaft of the telescopic drive cylinder is connected with a compression body. An outer periphery of the compression body is contacted with an inner wall of the filter interlayer.
