Novel physicochemical coagulation method sewage treatment device

Abstract

The invention discloses a novel physicochemical coagulation method sewage treatment device, which comprises a shell, wherein the shell is of a hollow structure, and a water inlet is formed in the upper side wall of the shell; a driving motor is arranged on the upper side wall of the shell, and a mounting block is laterally arranged on the inner wall of the shell; the mounting block is of a hollowstructure, and the output shaft of the driving motor penetrates through the shell and the side wall of the mounting block and is connected with a first rotating shaft; a downward-opening groove is formed in the lower side wall of the mounting block, and one side, away from the driving motor, of the first rotating shaft is laterally provided with a first gear; the first gear is positioned in the groove, and a tooth ring is arranged on the side wall of the groove; a first rotating disc is also sleeved on the side wall of the first rotating shaft. The novel physicochemical coagulation method sewage treatment device provided by the invention has the advantages of simple structure and convenient operation, can fully mix sewage and a flocculant, thereby achieving the ideal flocculation and sedimentation effect, and having sufficient sewage treatment and relatively high efficiency.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a new type of physical and chemical coagulation sewage treatment device. Background technique [0002] At present, the pollution of water resources in China is becoming more and more serious, and there is an urgent need to master sewage resource purification technologies suitable for the development of the times to alleviate the shortage of water resources. Traditional sewage treatment processes include chemical reaction method and physical precipitation method. In the sedimentation method, the commonly used flocculation sedimentation principle is a water treatment method in which colloids and fine suspended matter in the wastewater are coagulated into flocs under the action of flocculants, and then separated and removed. After adding the flocculant to the sewage, after mixing, the colloidal impurities in the water coagulate into larger alum particles, which are th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the medicament and sewage of the sewage treatment device in the prior art are statically mixed, so that the sewage cannot be completely mixed with the flocculant, resulting in the inability to achieve the effect of flocculation and sedimentation, and a new type of physical chemistry is proposed.
