Abstract

The invention relates to a materialization-biochemistry-plant combined water treatment device which comprises a water treatment pool.The water treatment pool comprises a water inlet section (1), a sewage treatment section (2) and a water outlet section (3) which are sequentially arranged in the flowing direction of sewage.The sewage treatment section (2) comprises an electrolytic section and a biochemistry and plant treatment section which are sequentially arranged in the flowing direction of sewage.A first water electrolysis assembly (21) for water electrolysis is arranged at the electrolytic section.The biochemistry and plant treatment section comprises an aeration layer, a microorganism filler layer and an emergent aquatic plant bed layer sequentially from bottom to top.Compared with the prior art, the treatment device has the advantages of being good in sewage treatment effect, stable in running, small in occupied area and the like.

Description

technical field [0001] The invention relates to a combined water treatment device, in particular to a physicochemical-biochemical-plant combined water treatment device. Background technique [0002] The microbial water treatment technology has been used for hundreds of years. The earliest urban sewage treatment plant in China, the Shanghai East District Sewage Treatment Plant, has a history of 90 years, and the sewage treatment principle of the 2 million-ton urban sewage plant such as Bailonggang Sewage Treatment Plant built in recent years It has been almost the same, and there has been no substantial change in the mechanism of microbial treatment. With the shortage of fresh water resources, higher requirements are placed on surface water quality, but it is difficult to further improve the water quality indicators of the effluent of traditional microbial sewage treatment processes, because the pollutants contained in the effluent are mainly microbial refractory organic matt...
