Integral phosphating wastewater treatment device

Abstract

The invention discloses an integral phosphating wastewater treatment device which comprises a rack, a machine shell, a liquid storage chamber, a pretreatment chamber, a reaction chamber, a residue treatment mechanism, a detection chamber, a clean water chamber, a liquid inlet, a liquid outlet and a control system, wherein the machine shell is mounted on the rack; the liquid storage chamber, the pretreatment chamber, the reaction chamber, the residue treatment mechanism, the detection chamber and the clean water chamber are sequentially arranged inside the machine shell; the liquid storage chamber, the pretreatment chamber, the reaction chamber, the residue treatment mechanism, the detection chamber and the clean water chamber are partitioned through side walls; the liquid storage chamber is connected with the liquid inlet; the clean water chamber is connected with the liquid outlet; the control system is mounted on the outer side of the machine shell. By adopting the integral phosphating wastewater treatment device, due to an integral structure of multiple treatment chambers, a waste liquid inside the liquid storage chamber passes through the pretreatment chamber, the reaction chamber, the residue treatment mechanism, the detection chamber and the clean water chamber for wastewater treatment in sequence, and the integral phosphating wastewater treatment device is low in manufacturing cost, simple in structure and convenient to operate.

Description

【Technical field】 [0001] The invention relates to the technical field of metal element production, in particular to the technical field of an integrated phosphating wastewater treatment device. 【Background technique】 [0002] In the production process of metal workpieces such as bolts and nuts, phosphating is a process of chemical and electrochemical reactions to form a phosphate chemical conversion film. The purpose is to provide protection for the base metal and prevent the metal from being corroded to a certain extent; Make a primer before painting to improve the adhesion and anti-corrosion ability of the paint film layer; it is used for anti-friction lubrication in the metal cold processing process. In addition to a large amount of phosphate, zinc ions, acid-base substances and organic matter, phosphating wastewater sometimes also contains a certain amount of heavy metals such as nickel ions, copper ions or lead ions, and surfactants, depending on the production process....
