Embodiment 1

[0016] A treatment agent for ortho- and m-aminobenzene wastewater comprises the following components in percentage by weight: 25% by weight of diisooctyl phosphate (P-204) and 75% by weight of kerosene.

[0017] The preparation method of the o- and m-aminobenzene wastewater treatment agent is as follows: sequentially add 25wt% of diisooctyl phosphate (P-204) and 75wt% of kerosene to the reactor, and stir for 100 minutes to obtain the o- and m-aminobenzene Benzene wastewater treatment agent.

Embodiment 2

[0019] A treatment agent for ortho- and meta-aminobenzene wastewater comprises the following components by weight percent: 25% by weight of 2-ethylhexyl phosphate (P-507) and 75% by weight of sulfonated kerosene.

Embodiment 3

[0021] A treatment agent for ortho- and m-aminobenzene wastewater comprises the following components in percentage by weight: 25% by weight of tributyl phosphate (TBP) and 75% by weight of n-hexane.

Abstract

The invention discloses an o-aminobenzene and m-aminobenzene wastewater treatment agent, which comprises the following components in percentage by weight: 10-50% of a complexing agent extraction compound and 50-90% of a complexing extraction agent diluent, wherein the complexing agent extraction compound is one or a plurality of materials selected from diisooctyl phosphate, 2-ethylhexyl phosphoricacid 2-ethylhexyl ester, tributyl phosphate (TBP), trioctyl phosphate, trioctylphosphine oxide, di(2-ethylhexyl phosphoric acid), di(2-ethylhexyl phosphoric acid) mono(2-ethylhexyl ester) and trioctyl / decyl tertiary amine, and the complexing extraction agent diluent is one or a plurality of materials selected from kerosene, sulfonated kerosene, n-hexane and dodecanol random polyether. The o-aminobenzene and m-aminobenzene wastewater treatment agent provided by the invention is good in treatment effect, high in efficiency and free of secondary pollution. The o-aminobenzene and m-aminobenzene wastewater treatment method provided by the invention is simple to operate, and can rapidly remove pollutants, and the treated wastewater meets the nanotube requirement.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an o- and m-aminobenzene wastewater treatment agent and a wastewater treatment method. Background technique [0002] The process wastewater generated during the production process of o- and m-aminobenzene as raw materials and products usually contains high acid, high salt, and high COD, and biochemical and physicochemical methods have no obvious beneficial treatment effect on it. The existing technology generally adopts physical and chemical methods for treatment, but the existing physical and chemical methods cannot meet the requirements of water quality discharge and pipe collection, and can only be discharged and piped after dilution. Contents of the invention [0003] The purpose of the present invention is exactly for the existing ortho- and meta-aminobenzenes as the raw material and the defects in the process wastewater treatment agent and treatment method pr...
