AI Technical Summary

Problems solved by technology

[0004] The biochemical decomposition method must first dilute the sewage hundreds of times before carrying out biochemical treatment. The investment is large, and the average treatment of one ton of wastewater costs 300 yuan. The production cost is high and a lot of water resources are wasted.
[0005] Chemical oxidation, using potassium permanganate or ozone oxidation, has high cost and high technical requirements, and is difficult to popularize
[0006] The extraction recovery method uses organic solvents (such as coal tar) as the extraction agent, the extraction rate is low, the highest is less than 90%, and the phenol content in the treated wastewater still exceeds the standard by thousands of times, and biological dephenolization treatment is required, and the process is complicated. High cost and unsatisfactory treatment effect

Abstract

The invention relates to a treating agent for removing methanal, methyl alcohol and phenol in phenolic resin workshop wastewater, compounded from the following components of 2-tridecanone, 4-sodium parachlorophenoxy, fritillarine, thiodipropionicacid dilauryl ester, rotundic acid, 4-acetoxyl-3-methoxy-(2-allyl)benzene, lobelanidine HCL, 4-octylphenol ethoxylate, 3',4'-dyhydroxy-2-(methylamino)acetophenone hydrochloride, and the like. The treating agent is strong in complexing power with a target substance, quick in complex precipitate forming speed, little in usage amount, and free of damage to a water body, and has a removal rate of 99.9 percent.

Description

technical field [0001] The invention relates to a treatment agent for removing formaldehyde, methanol and phenol in wastewater from a phenolic resin workshop, and belongs to the technical field of environmental protection. Background technique [0002] Phenolic resins are polymerized from phenol and formaldehyde under certain conditions, and are widely used in bakelite composite materials, anti-corrosion materials, binders and paints. A large amount of high-concentration phenol-containing wastewater is produced in the production process of phenolic resin. Because phenol is a highly toxic and highly corrosive chemical substance, it is extremely toxic to most organisms, can cause protein denaturation and coagulation, and eventually lead to tissue failure and death. Therefore, if these wastewaters are directly discharged into natural water bodies without treatment, it will cause serious damage to the natural environment on which we live. The U.S. National Environmental Protec...
