Problems solved by technology

In the implementation process of this application, the sewage pretreatment process was not enough, and the harmful components in the sewage were not completely removed, which increased the pressure in the subsequent treatment, and did not select the precipitant in the reaction process, so the COD treatment effect in the wastewater bad

Embodiment 1

[0053] Embodiment 1 A kind of esterification wastewater treatment process

[0054] Include the following steps:

[0055] (1), the esterification wastewater is passed into a grease trap, and the grease in the wastewater is removed through the grease trap to obtain sewage 1.

[0056] (2), adjust the water quality of the sewage 1, pump the sewage into the multi-dimensional electrocatalytic reaction tank and the external circulation Fenton oxidation tank for oxidation reaction, and obtain the sewage 2;

[0057] (3), adjust the pH value of sewage 2 to 7, and then add a mixture of GP01, GP02, GP03, GP04 and GP05 with a mass ratio of 1:2:2:2:1 and polyacrylamide to make the impurities in the sludge The reaction generates sedimentable sludge, and the supernatant flows into the regulating tank after sedimentation in the sedimentation tank to obtain sewage 3;

[0058] (4), Sewage 3 is transported to the hydrolytic acidification tank after being regulated by the regulating tank, and ba...

Abstract

The invention provides an esterification wastewater treatment process and relates to the technical field of wastewater treatment. The present invention adopts the complementary process of multi-dimensional electrocatalysis and external circulation Fenton oxidation tank process. This process combination doubles the degradation effect of organic matter and greatly reduces the dosage of medicaments. Although the Fenton process is adopted, this process does not introduce any sulfate radicals. No sulfides that are toxic to microorganisms will be produced in the anaerobic stage, which can ensure that the biological system can exert the maximum treatment effect. The fixed bed catalytic oxidation filter is used in the operation process. The catalytic oxidation process does not adjust acid and alkali. , No sludge production, the catalyst can promote the full decomposition of hydrogen peroxide and produce hydroxyl radicals and form a series of comprehensive redox reactions to achieve strong oxidation and decomposition of organic matter, while filtering sewage, and at the same time reduce COD, suspended solids, improve B / C value and other functions.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment process for esterification wastewater. Background technique [0002] Synthetic resin paint is a kind of high molecular polymer artificially synthesized. The esterification wastewater generated during its production process has the characteristics of high organic content and low biodegradability. With the improvement of the economic level, the production volume of my country's coatings has also increased year by year, but the production process and characteristics of various coatings at this stage have determined that a large amount of toxic and harmful industrial wastewater will be produced in the production process. With the development of my country's coatings industry With the rapid development, the treatment of paint wastewater has increasingly become an environmental issue that requires high attention; most of the various paints in the production proc...
