Embodiment 1

[0038] A treatment process for ester-containing organic waste water, comprising the steps of:

[0039] If a large amount of ammonia-containing substances have been mixed in the wastewater to be treated, the pH of the wastewater to be treated must be adjusted to above 10. First carry out the atomization and absorption treatment of vacuum deamination, and continuously reflux the treated liquid obtained by condensation until the pH is 8; then add flocculant to the obtained wastewater to remove methyl, hydroxyl, ether, phenol and other chemicals derivative. If there are no these ingredients can not be added, to obtain the treatment solution I;

[0040] Add acid to the treatment solution I, adjust the pH to 2, add hydrogen peroxide and FeSO 4 Doped with Ti, FeSO 4 The doped Ti is added in the form of a solution, and its volume concentration is 0.1% of the total liquid to obtain the treatment solution II, which is left overnight;

[0041] Pour the treatment solution II into the ...

Abstract

The invention provides a treatment method and technology of industrial wastewater-ethylhexyl thioglycolate wastewater. According to the method, graphene is taken as an electro-fenton device of an electrode to perform deep oxidation on poisonous and harmful chemical liquid. The method comprises the steps of firstly adding an oxidizing agent to remove part of ethylhexyl thioglycolate, and performingelectro-fenton energized oxidation to achieve the purpose of sufficiently removing ethylhexyl thioglycolate, adding alkali till the pH value is 10 or greater than 10, then performing decompression blowoff on obtained liquid, and absorbing produced ammonia with acids to sufficiently remove an ammonia nitrogen substance. By adopting the treatment method of the ethylhexyl thioglycolate wastewater, the technical problems of difficulty in degradation, low treatment efficiency, large floor space, high investment cost and the like under the existing biotechnological framework can be solved, and thetechnical effect of removing organic matter of high-concentration demineralized mother liquor can be achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and relates to a treatment process for ester-containing organic waste water, in particular to a treatment process for waste water containing isooctyl thioglycolate. Background technique [0002] Isooctyl thioglycolate is a commonly used plastic stabilizer, and is an important intermediate and catalyst in the fields of pesticides, medicine, organic synthesis, and fine chemicals. The production of this substance uses chloroacetic acid, isooctyl alcohol, sulfuric acid, and the waste water is often mixed with impurities from other sources such as organic ammonia. High toxicity and non-biodegradable, the existing microbial water treatment technology cannot provide effective treatment means, and the impact of sewage discharge on the environment is great. [0003] Electro-Fenton technology can generate a large number of OH free radicals during artificial discharge, and OH free radicals...
