Abstract

The invention belongs to the technical field of rubber chemical wastewater treatment and particularly relates to a water purifier for production of a rubber accelerator DZ and a wastewater treatment method. The water purifier for production of the rubber accelerator DZ comprises a solid adsorption material, a microbial water purifier and an enzyme preparation. The solid adsorption material is prepared from, by weight, 10-25 parts of medical stone, 5-20 parts of active coke and 5-15 parts of slag; the microbial water purifier is prepared from, by weight, 0.5-2.0 parts of phosphorus-accumulating bacteria powder, 0.4-1.4 parts of geotrichum candidum powder, 0.2-0.8 part of white rot fungi powder and 0.3-1.2 parts of microbacterium powder; the enzyme preparation comprises, by weight, 0.05-0.1 part of manganese catalase, 0.04-0.12 part of oxidoreductase, 0.03-0.08 part of streptomyces protease and 0.02-0.1 part of nitrile hydratase. By joint action of the solid water purifier, the composite microbial agent and the enzyme preparation to wastewater, secondary pollution caused by chemical treatment is avoided, sewage discharging amount is decreased, and quality of treated wastewater is improved. In addition, by the wastewater treatment method, CODcr discharging amount reaches national specified standards.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment of rubber additives, and in particular relates to a water purifying agent used in the production of rubber accelerator DZ and a waste water treatment method. Background technique [0002] In recent years, with the vigorous development of my country's automobile industry, it has driven the development of the tire industry, which in turn has stimulated the development of the rubber additives industry. As an important auxiliary raw material in the rubber industry, rubber additives play an important role in improving rubber processing technology and product quality. Rubber additives are usually divided into three categories: antioxidants, vulcanization accelerators and processing aids. Among them, the vulcanization accelerator can shorten the physical and mechanical properties of rubber, and is one of the indispensable compounding agents in rubber. [0003] There are many types of acce...
