A kind of wastewater treatment device for biphenyl dichlorobenzyl production

Abstract

The invention discloses a waste water treatment device for the production of biphenyl dichlorobenzyl, which relates to the technical field of sewage treatment, and comprises a support seat, the support seat has a cylindrical structure, and a treatment tank is arranged inside the support seat. And the peripheral outer wall of one end of the treatment tank is fixedly installed with an attached outer ring plate, and the attached outer ring plate and the supporting seat are rotatably connected by a sealed bearing. The assembly includes an inner end column that is rotatably connected to the center of the top of the treatment tank, and a cavity is provided at one end of the inner end column near the top; the present invention utilizes the set cavity, the connecting inclined tube and a plurality of spiral inner tubes, and can be added When the medicine is used, it is evenly added to both sides of the steady flow cylinder through multiple one-way valve tubes, which is conducive to the full mixing and reaction of the medicine and wastewater; the set steady flow cylinder and steady flow swing plate can play a good role in the flowing liquid The blocking effect allows the liquid to quickly level off.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a waste water treatment device for the production of biphenyl dichlorobenzyl. Background technique [0002] Pure water changes its original physical or chemical properties after use, and becomes wastewater containing different types of impurities. Chemical wastewater is the process wastewater, cooling water, exhaust gas washing water, equipment and site washing water and other wastewater discharged in chemical production. If the waste water is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health; biphenyl dichlorobenzyl is an important organic chemical intermediate, and the wastewater produced by biphenyl dichlorobenzyl belongs to high-grade Salt wastewater contains a large amount of impurities. In the actual preliminary treatment, it is necessary to add chemicals and reac...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned comparative documents have the following deficiencies: the above-mentioned patent does not carry out detailed treatment on the design of dosing and reaction, the conventional dosing method cannot achieve uniform feeding, and the mixing of medicament and wastewater takes a period of time, and then prolongs In addition, the stirring design in the prior art cannot effectively assist the steady flow of the liquid after the work is stopped, and the steady flow time of the liquid is longer, which makes it difficult for the actual sediment to sink quickly, which further affects the work. efficiency, so there are certain limitations
