AI Technical Summary

Problems solved by technology

Generally, these methods cannot completely oxidize and degrade toxic and harmful organic pollutants such as DMF and DMAC in wastewater, so they can only be used as pretreatment, not as final treatment process; and the economic cost of these current treatment methods is too high. As a result, many enterprises cannot put into production
According to the data, there is no mature technology that can be used in production practice at home and abroad.

Embodiment Construction

[0026] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention.

[0027] See attached figure 1 Shown, introduce a kind of waste water treatment method that contains dimethylformamide, dimethylformamide, it comprises the following steps

[0028] Step a: import waste water containing dimethylformamide and dimethylformamide into an aerated catalytic micro-electrolytic cell 1 made of PVC or stainless steel;

[0029] Carry out step b at least once: Dimethylformamide and dimethylformamide are electrolyzed by the primary battery filler in the aerated catalytic micro-electrolytic cell 1, the primary battery filler is a mixture of catalyst and iron filings, and then the The electrolyzed waste water is introduced into the first regulating pool 2 to regulate the water quality of the waste water;

[0030] Step c that is performed at least once: import the adjusted wastewater into the catalytic electro-oxida...

Abstract

The invention discloses a treatment method for waste water containing dimethyl formamide. The method comprises the following steps: introducing waste water into an aeration catalyzing micro cell, electrolyzing the waste water by the primary cell filling in the aeration catalyzing micro cell, carrying out the steps of oxidization and the like by the catalyst electrode waste water on the catalyst electrooxidation reactor; the treatment method integrates various materialization methods such as electrolysis, catalysis, oxidization, absorption, coagulation and the like to form a highly efficient reinforcement and materialization integrated technology, thus completely oxidizing toxic and harmful organic pollutants such as DMF, DMAC and the like. The invention has the advantages of high treatment efficiency, low operation cost, capable of being industrialized and the like.

Description

[technical field] [0001] The invention relates to a treatment method and a treatment device for sewage and waste water, more specifically, the invention relates to a treatment method and a treatment device for waste water containing dimethylformamide and dimethylformamide. [Background technique] [0002] Dimethylformamide (DMF) and dimethylacetamide (DMAC), as excellent organic solvents and main fine chemical raw materials, are widely used in pharmaceuticals, petrochemicals, synthetic fiber industries, and synthetic leather industries. Because there are two methyl groups at the molecular ends, no chemical reaction occurs, and there is no consumption in quantity, and all of them enter the production wastewater. DMF is biologically toxic, and after being discharged into water, it inhibits microbial activity and seriously pollutes water; DMF can enter the body through the respiratory tract, digestive tract and skin, and is also toxic to a certain extent. China's Occupational E...
