Abstract

A wastewater treatment device for a paper mill is disclosed. The device includes a main body. The bottom of the inner cavity of the main body is fixedly connected to an aeration chamber the top of which is fixedly connected to a fixed base. A motor is fixedly mounted at one side of the fixed base. The rotating shaft of the motor is in transmission connection with a stirring shaft through a coupler. The bottom end of the stirring shaft penetrates the top of the aeration chamber and extends into the aeration chamber. The bottom of the stirring shaft is welded to stirring plates. The left side ofthe main body is fixedly connected to a water feeding pipe. Through arrangement of a water stopper ring, a water stop bolt, a shell, a Y-shaped ventilation screw and a cushion plate, the water stopper ring and the water stop bolt maintain structure leakproofness, air flows into the Y-shaped ventilation screw through a branch pipe and then is fed into wastewater from the top end of the Y-shaped ventilation screw, thus greatly increasing the content of dissolved oxygen in wastewater, accelerating oxidation reaction and making oxidation more thorough, and therefore organic matters are fully decomposed and sludge is discharged from a drainage pipe.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for paper mills. Background technique [0002] Papermaking is one of the four great discoveries in ancient my country. It is the crystallization of human wisdom. The appearance of paper facilitates people's lives. The printing of textbooks accelerates the progress of human civilization and has a great impact on the development of society and technology. Until now, paper is An indispensable product in daily life, the modern papermaking process can be divided into steps such as pulping, modulation, papermaking and processing. Pulping is to use mechanical methods, chemical methods or a combination of both to dissociate and transform plant fiber raw materials. When the cost-colored pulp or bleached pulp is directly discharged to the outer boundary, it will cause serious damage to the environment, and the current papermaking wastewater treatment measur...
