Problems solved by technology

[0002] The rubber industry is one of the major drainage households in the petrochemical industry. Its drainage water quality is complex and changes greatly. For example, rubber accelerator wastewater contains more refractory organic matter. It is difficult to achieve the ideal by direct physical clarification or chemical reagent treatment. Governance effect
The wastewater produced in the synthetic rubber production process has a large amount of discharge and strong toxicity. If it is discharged directly without treatment, it will seriously pollute the ecological environment. At the same time, due to the complex water quality and high organic content of rubber wastewater, it is very difficult to treat, especially It is the wastewater discharged from the production of styrene-butadiene rubber
Generally, the production of chloroprene rubber adopts the calcium carbide method, and a large amount of high-concentration organic wastewater is produced during the production process. The water is highly toxic and contains a large amount of organic matter that is difficult to biodegrade, such as benzene series, dispersants, curds, etc. Such as acetylene, acetaldehyde, chloroprene, benzene, chlorobenzene, copper, etc., are industrial wastewater that is seriously polluted and extremely difficult to treat. The treatment of this wastewater has always been a difficult problem for enterprises, and related very little research
