The comprehensive treatment of industrial wastewater and its recovery and utilization technology

Abstract

With the acceleration of industrialization in China, the phenomenon of industrial pollution has become more and more serious, which has caused a great hazard on the ecological environment. The quantity and scale of industrial wastewater continue to increase, and higher requirements are put forward for the treatment of industrial wastewater. Firstly, this paper analyzes the function and importance of industrial wastewater treatment. Secondly, we proposed the comprehensive treatment of industrial wastewater and its recovery and utilization technology. The comprehensive treatment of industrial wastewater is completed by the backwashing of biochemical tank, the dehydrating of sludge thicker and the effluent from disinfecting tank. The recovery and utilization technology of industrial wastewater is designed. By recovery industrial wastewater, the usage amount of reuse water is increased.
