Sewage treatment device

Abstract

The invention discloses a sewage treatment device. The sewage treatment device comprises a base body, and a chlorine adding device which is fixedly arranged on the top of the base body; the chlorine adding device is composed of a fist pedestal, and second pedestals arranged on the left side and the right side of the first pedestal; a first cavity designed to stretch to the left and the right is arranged in the first pedestal; a first rotating rod designed to stretch to the left and the right is arranged in the first cavity; a motor is arranged in the internal top surface of the first cavity; afirst conical wheel designed to stretch into the first cavity is connected with the bottom of the motor through cooperative connection; the right side end of the first conical wheel is connected witha second conical wheel which is fixedly arranged on the external surface of the first rotating rod through meshing; guide slide grooves are arranged in the left side and the right side of the first pedestal above the first cavity; the left guide slide groove and the right guide slide groove are arranged above the left stretching part and the right stretching part of the first cavity. The sewage treatment device is simple in structure; operation is convenient; device operation stability is increased; a plurality of spraying requirements can be satisfied; it is convenient for moving and transportation; and efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of environmental protection sewage treatment, in particular to a sewage treatment device. Background technique [0002] With the further strengthening of new rural construction, the centralized treatment and discharge of rural sewage has become a new problem. In rural areas, sewage is mainly domestic sewage. In the past, these sewage were directly discharged into creeks and rivers without treatment, seriously affecting water quality and environmental landscape. At present, the rural sewage treatment system first collects the sewage into the sewage pool, and then discharges it into the river through a series of procedures such as sedimentation and chlorination. In the chlorination process, liquid chlorine chlorination is the most commonly used method. After the liquid chlorine is vaporized and put into water through a chlorinator, the oxidation and chlorination can be completed. However, the existing liquid ...

Problems solved by technology

In the chlorination process, liquid chlorine chlorination is the most commonly used method. After the liquid chlorine is vaporized and put into water through a chlorinator, the oxidation and chlorination can be completed. However, the existing liquid chlorine chlorination system is relatively complicated and the cost is high. , the one-piece mechanical structure has only one chlorine addition direction, and cannot adapt to the disinfection treatment of sewage pools in different directions
