Various sewage treatment methods(2)

Oct 09, 2017

Method 1, in the production process to reduce the proportion of oil in the emulsion of emulsification.

    Method 2, in the water treatment process, to minimize the number of times to enhance the use of the pump, so as not to increase the degree of emulsification. Treatment methods are usually carried out by air floatation and demulsification. Through the above method can effectively solve the emulsified oil and scattered oil difficult to deal with the problem.

    Chemical wastewater treatment First, the source of chemical wastewater Chemical industry wastewater mainly from the petrochemical industry, coal chemical industry, acid and alkali industry, fertilizer industry, plastics industry, pharmaceutical industry, dye industry, rubber industry and other discharge of waste water.

   Second, the water treatment methods 1. Reform of production technology and equipment, reduce pollutants, to prevent waste effluent, comprehensive utilization and recycling. 2. Wastes that must be discharged from the effluent must be treated according to the water quality and requirements. Primary water treatment mainly separates suspended solids, colloids, oil slick or heavy oil from water. Can be used to adjust water quality, natural precipitation, floating and oil and other methods.

    Secondary water treatment is mainly to remove the biodegradable organic lysates and some colloids, reduce the waste water in the biochemical oxygen demand and some chemical oxygen demand, usually using biological treatment. After the biological treatment of waste water, but also a considerable amount of COD, and sometimes a higher color, smell, taste, or because of environmental health standards require high, you need to use three water treatment methods for further purification.
