Abstract

The invention discloses a stirring knife for sewage treatment, characterized by comprising a knife handle and a knife edge, wherein the knife handle is composed of two sections, the first section is flat, and the second section is cylindrical; the flat part is connected with the cylindrical part; the cylindrical knife handle part is connected with the knife edge part; and the flat part comprises a bolt hole for fixed connection. The stirring knife for sewage treatment can adequately stir, cut some solid precipitates and accelerate processing progress.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a mixing knife and a using method thereof. Background technique [0002] With the increasingly serious environmental pollution, people have higher and higher requirements for the environment, and environmental pollution, especially water pollution, has directly affected people's daily life and future drinking water safety. Research on the manufacture of sewage treatment equipment It is currently of great concern to the industry. For example, Chinese patent publication CN101862553A provides a coagulation reaction device and a sewage treatment system. The coagulation reaction equipment includes a pool body, and the pool body is connected with water inlets and outlets. The pool body is divided into three areas by the first partition and the second partition, the upper or lower parts of the first and second areas are connected, and the lower or upper parts of the second and third areas ...
