Problems solved by technology

However, the disadvantage of the SBR method is that on the one hand, it has higher requirements on the control system. On the other hand, since the anaerobic and aerobic reactions are carried out alternately, its essence is to complete the anaerobic reaction and aerobic reaction alternately in the same reaction tank. Reaction, unable to exert the processing ability of anaerobic flora and aerobic flora at the same time
Therefore, the SBR method only partially solves the shortcomings of the large footprint of A2 / O by sacrificing system processing capacity, and is not a solution to the A2 / O method.

Abstract

The invention relates to the field of water treatment, in particular to a water treatment system, which comprises an anaerobic reaction device and an aerobic reaction device, wherein the anaerobic reaction device is in fluid communication with the aerobic reaction device; the anaerobic reaction device comprises an anaerobic reaction tank body and a grid for dividing an internal space of the anaerobic reaction tank body into an isolated area and a filler area which are in fluid communication with each other; a water inlet of the anaerobic reaction device is positioned in the isolated area; a water outlet of the anaerobic reaction device is positioned in the filler area; an anaerobic reaction filler is arranged in the filler area. According to the water treatment system, systems for an A2O water treatment method can be effectively integrated, and in addition, air can float to wash the surface of a filter membrane, so that the effects of greatly reducing the energy consumption and saving an occupied area can be achieved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water treatment system. Background technique [0002] In recent years, with the rapid development of the national economy, the discharge of industrial wastewater has continued to increase, and the difficulty of treatment has continued to increase. Especially in cities with tight land use, the treatment of industrial wastewater has become an urgent problem for enterprises to solve. [0003] As the core link of industrial wastewater treatment, biochemical treatment directly restricts the overall treatment effect of industrial wastewater. The traditional biochemical treatment needs to distribute the pretreated wastewater into the anaerobic pond, aerobic pond, and sedimentation pond, and then meet the discharge requirements after advanced treatment, which is commonly referred to as the A2 / O treatment method. A2 / O can make pollutants complete anaerobic and aerobic biochemical degrad...
