Dyestuff pesticide waste water treatment device

Abstract

The present invention provides a processing unit of dyestuff, pesticide and waste. The invention relates to an equipment of treating, separating and recovery pesticide and dyestuff by nanofiltration combined process. The unit is composed of linked water inlet, a water storage tank, a supercharge pump, a carbon filter, a microstrainer or millipore filter, a water outlet in orders, a linked high pressure pump, a check valve, a filter are set between water outlets in orders, a recovery outlet is set on the filter. Waste after being treated is processed with normal biological treatment, suitable for engineering application, the technology is not only a new clean producing technology of the dyestuff, pesticide production, but also a creation of the dyestuff, pesticide waste treating process, the technology has a high intensification, lower occupation, high automation degree, convenient control management, wide engineering application.

Description

technical field [0001] The invention relates to equipment for treating, separating and recovering dye and pesticide wastewater by a combined nanofiltration process. technical background [0002] Dyestuffs and pesticides are important products of fine chemicals, with a wide variety, including tens of thousands of varieties including intermediates in the production process. And sulfonic acid group, azo group, hydroxyl group, carbonyl group, carboxyl group, nitro group, amino group and other active groups. The molecular structure of the dye substance is stable, and the new product uses anti-oxidation, anti-photochemical, and anti-biochemical as product quality indicators; the structure of the pesticide contains toxic groups such as phosphorus and chlorine, which have a serious killing effect on microorganisms. Dye and pesticide wastewater is an internationally recognized source of heavy industrial pollution, and its treatment is a major environmental issue of great concern to ...

AI Technical Summary

Problems solved by technology

Biological method is one of the more commonly used methods at present. Its main advantage is that the treatment cost is low, but it must be diluted dozens to hundreds of times before it can be processed. Even so, it is still difficult to meet the standard

Physical and chemical methods mainly include adsorption method, solvent extraction method, micro-electrolysis method, catalytic oxidation method, etc. These methods are high in cost and poor in effect, and are difficult to implement in engineering applications
