Fuzhou industrial waste _ _ rich industrial wastewater treatment engineering students

In recent years, there have been new methods and techniques for the treatment of industrial waste water, but each has advantages and disadvantages. Biological oxidation of pure water contains a certain amount of refractory organics, COD value is high, it can not fully meet the emission standards. Although adsorption can better remove COD, but there are regeneration of the adsorbent and the secondary pollution. Although catalytic oxidation can degrade poorly biodegradable organic matter, but there are practical problems of higher operating costs of industrial applications. Especially now that the industrial wastewater pollutants are diverse, often with a process that can not be all of the contaminant removal in wastewater depleted. Chemical and physical processes with industrial wastewater discharge standards to great difficulty, and higher operating costs; industrial waste containing more refractory organic matter, poor biodegradability, waste water and industrial waste water quality changes is large, it is to deal directly with biochemical methods the effect is not very satisfactory industrial wastewater. Guangzhou Fu Yi Zhang Qing state students green bin along firecrackers papermaking wastewater treatment works: the characteristics of industrial wastewater treatment, we believe that its treatment should take appropriate pretreatment method according to the actual quality of wastewater, such as flocculation, inner electrolysis, electrolysis, absorption, light Catalytic oxidation and other processes, refractory organics in wastewater damage, improve the biodegradability of wastewater; and then combined with biochemical methods, such as SBR, contacts oxygen industrial arts, A / O process, etc., in-depth treatment of industrial waste water. Industrial wastewater treatment, although in the 19th century had begun, and in the subsequent half century a lot of experimental research and production practice, but because of many complex components of industrial waste water, changing the nature of some of the technical issues are still not fully resolved. Industrial waste refers to industrial waste water generated in the process, sewage and waste water containing pollutants with the loss of industrial materials, intermediate products and production process produces. With the rapid development of the type and quantity of the rapid increase of industrial water pollution are becoming increasingly widespread and threaten human health and safety. Therefore, for the protection of environment, industrial wastewater treatment is more important than urban sewage treatment.
