Working method of printing and dyeing industrial sewage treatment device

Abstract

The invention relates to the technical field of printing and dyeing sewage treatment. The invention particularly relates to a working method of the printing and dyeing industry sewage treatment device. Including a base, the device further comprises a controller, a separation mechanism, a decoloration mechanism and a sterilization mechanism. The separation mechanism comprises a separating box and afiltering assembly, the decoloration mechanism comprises a reaction box and a proportioning assembly, the sterilization mechanism comprises a sterilization box, a stirring assembly, a sterilization assembly and a power supply assembly, the disinfection box is fixedly arranged at the top of the base, the stirring assembly is arranged in the disinfection box, the sterilization assembly is arrangedin the sterilization box and is positioned above the stirring assembly, and the proportioning assembly, the stirring assembly, the sterilization assembly and the power supply assembly are all electrically connected with the controller. According to the printing and dyeing industry sewage treatment device and the working method, solid-liquid separation can be preliminarily achieved, meanwhile, thedecoloration and disinfection effects are better, and the sewage treatment efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing sewage treatment, in particular to a working method of a printing and dyeing industrial sewage treatment device. Background technique [0002] Wastewater discharged from printing and dyeing, wool dyeing and finishing and silk factories mainly processing cotton, hemp, chemical fiber and their blended products, and silk. These printing and dyeing wastewater need to be treated before they can be discharged. Traditional treatment methods usually reduce the COD of wastewater through adsorption, filtration, coagulation, biochemical and other processes. However, under the above method, the removal effect of toxic substances and chroma in wastewater is poor, and the printing and dyeing water obtained after treatment is often difficult to meet the discharge standard, and the input cost of raw materials is very high.

AI Technical Summary

Problems solved by technology

[0006] 1. No solid-liquid separation structure is involved. Before sewage treatment, solid-liquid separation must be carried out first, that is, the solid waste or substances in the sewage should be filtered out from the sewage, so as to facilitate the subsequent treatment process

[0007] 2. The process of sewage treatment is relatively simple. After the decolorization treatment, the inside of the tank cannot be cleaned up in a timely and effective manner. It is easy to cause blockage of the tank during subsequent operations, thereby delaying the treatment efficiency. At the same time, the sewage disinfection treatment method uses Routine operation of neutralization reaction with limestone, the efficacy of disinfection needs to be improved
