Integrated biological contact oxidation-aeration biofilter

Abstract

The invention relates to the technical field of sewage treatment, in particular to an integrated contact oxidation-aeration biofilter. The integrated contact oxidation-aeration biofilter comprises a reaction area and a power system control area disposed below the reaction area, wherein the reaction area is in a rectangular box shape, the inner part of the reaction area is divided into a contact oxidation area, a precipitation area, a hydrolysis acidification area, an aeration biofilter area and a clean water area from left to right, sewage enters from a water inlet flange on the upper side ofthe contact oxidation area on the leftmost side, and the sewage successively passes through each reaction area and is discharged up to the standard by virtue of a main water outlet on one side of theclean water area on the leftmost side; and the power system control area is disposed inside an operating platform, a Roots fan, a standby Roots fan, a power control cabinet and a backwashing pump arearranged in the power system control area, and one side of the operating platform is provided with a steel step. Compared with an artificial wetland, the integrated contact oxidation-aeration biofilter disclosed by the invention has the advantages of small floor area, stable water quality and easiness in management and maintenance.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated contact oxidation-aerated biological filter. Background technique [0002] my country is a large agricultural country with a rural population of over 800 million. However, due to the weak awareness of pollution treatment for a long time, 96% of the villages have no drainage channels and sewage treatment systems, and a large amount of sewage is discharged directly without treatment, polluting the surrounding water bodies and soil, and seriously threatening the safety of groundwater and the health of rural residents. Compared with urban sewage, rural domestic sewage is widely scattered and discharged randomly, which is not suitable for centralized treatment of urban sewage. Therefore, it is necessary to establish a treatment method suitable for rural characteristics. [0003] The current widely used rural domestic sewage treatment technologies include "artif...

Problems solved by technology

The effluent quality of "constructed wetland and oxidation pond technology" fluctuates greatly with seasonal changes, and the treatment effect cannot be effectively guaranteed in autumn and winter when plants grow slowly; while the "integrated MBR reactor technology" has a good treatment effect, but the system purchase cost High, strict management requirements, especially the long-term maintenance of MBR membrane is more difficult
