Dithioformate containing wastewater treatment device

Abstract

The invention discloses a dithioformate containing wastewater treatment device. Dithioformate containing wastewater has large physiological toxicity to microorganisms, and is extremely unfavorable forbiochemical reactions. The dithioformate containing wastewater treatment device provided by the invention comprises a filtering module, a reaction module, a condensation and recovery module, a firstmixing module, a second mixing module, a heating module, a blow-off module, an elution module, a first detection flow channel, a first pH detector, a second detection flow channel and a second pH detector, wherein the reaction module comprises a reaction pool, a nitrogen storage tank, a fourth on-off valve, a bottom aeration pipe, a baffle plate group, a molecular sieve placement box, a folded plate aeration pipe and a partition plate group; and the condensation and recovery module comprises a condensation tower, a nitrogen liquefaction device, a spiral pipe, a fifth on-off valve and a carbondisulfide collection box. The dithioformate containing wastewater treatment device provided by the invention can independently separate dimethylamine and carbon disulfide from the dithioformate containing wastewater, reduces the pollution degree of wastewater, and greatly improves economic benefits at the same time.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a treatment device for wastewater containing dithioformate. Background technique [0002] The thiram pesticides have the characteristics of strong antibacterial property, long-lasting effect and strong penetration in dead tissue parts, and have control effects on various diseases of various crops, so they are widely used in agricultural production. Dithioformate is an active ingredient in thiram pesticides. Therefore, in the production of thiram pesticides, it is inevitable to produce pesticide wastewater containing dithioformate. Pesticide wastewater containing dithioformate cannot be discharged directly, so wastewater treatment is required. However, the pesticide wastewater containing dithioformate has a great physiological toxic effect on microorganisms, which is extremely unfavorable to the growth and reproduction of microbial systems and the effici...

AI Technical Summary

Problems solved by technology

However, the pesticide wastewater containing dithioformate has a great physiological toxic effect on microorganisms, which is extremely unfavorable to the growth and reproduction of microbial systems and the efficiency of biochemical treatment in the process of biochemical reaction purification of wastewater, which is easy to cause microbial poisoning and is difficult to biodegrade

Therefore, it is difficult for the conventional biochemical reaction to treat wastewater to play a significant role in the treatment of dithioformate-containing pesticide wastewater.
