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 fatification wastewater treatment process

[0054] Include the following steps:

[0055] (1) Pass the lipidated waste water into the grease trap, and remove the grease in the waste water 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;

Abstract

The invention provides an esterification wastewater treatment process, and relates to the technical field of wastewater treatment. According to the invention, a multi-dimensional electro-catalysis process and an external circulation Fenton oxidation tank process supplement each other, so the degradation effect of organic matters is doubled, and the dosage of chemicals is greatly reduced; although a Fenton process is adopted, no sulfate radical is introduced in the process, sulfides having toxic effects on microorganisms cannot be generated in an anaerobic stage, a biological system can be ensured to exert the maximum treatment effect, a fixed bed catalytic oxidation filter tank is adopted in the operation process, acid and alkali are not adjusted, and mud is not produced in the catalytic oxidation process; the catalyst can promote sufficient decomposition of hydrogen peroxide, generate hydroxyl radicals and form a series of comprehensive oxidation-reduction reactions, so strong oxidative decomposition of organic matters is realized, meanwhile, sewage is filtered, and meanwhile, the effects of reducing COD and suspended matters, improving B / C value and the like can be realized.

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 esterified wastewater generated in the 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 process invo...
