Self-forming dynamic membrane biological reaction sewage treatment device

Abstract

The invention discloses a self-forming dynamic membrane biological reaction sewage treatment device comprising a reaction pool, clapboards and a grid well and forming biological reaction areas, biological transition areas and a clean water area. Special biological fillers and a microporous aerator are arranged in each biological reaction area, a self-forming dynamic membrane device is arranged in the grid well, a water discharge pipe is arranged in the clean water area, and a guide plate is arranged below the clean water area. The self-forming dynamic membrane biological reaction sewage treatment device disclosed by the invention has the advantages of simple structure, low floor area, low investment, good treatment effect, low running cost, no needing of operation and management of specially-assigned person and the like, thereby being very suitable for requirements on the current small towns and countries for sewage separating treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a self-generated dynamic membrane biological reaction sewage treatment device suitable for the dispersed treatment of domestic sewage in small towns and rural areas. Background technique [0002] With the rapid development of social economy, the ecological environment has also been damaged, and the pollution and eutrophication of natural water bodies have become increasingly serious, especially in small towns and rural areas in some remote areas. Due to the scattered residences in the villages, domestic sewage is not easy to be treated centrally. The sewage of most houses and farmers is directly discharged without any treatment or simply treated in septic tanks, which makes the natural environment worse. The pollution of domestic sewage in small towns and rural areas has become an important problem that must be solved in environmental protection. Therefore, Methods for d...

Problems solved by technology

[0002] With the rapid development of social economy, the ecological environment has also been damaged, and the pollution and eutrophication of natural water bodies have become increasingly serious, especially in small towns and rural areas in some remote areas. Due to the scattered residences in the villages, domestic sewage is not easy to be treated centrally. The sewage of most houses and farmers is directly discharged without any treatment or simply treated in septic tanks, which makes the natural environment worse. The pollution of domestic sewage in small towns and rural areas has become an important problem that must be solved in environmental protection. Therefore, Methods for domestic sewage treatment in small towns and rural areas have been introduced, the most common of which is the artificial wetland method. This sewage treatment method has become the current domestic sewage dispersion method due to its simple process structure, low engineering investment, convenient operation and management, and low operating costs. The preferred process for treatment has been widely used in small towns and rural areas. However, the artificial wetland method has a simple process structure, but it has imperfect biochemical processes, large land occupation, low pollutant load, unstable operation, and hydraulic pressure. Therefore, the treatment effect of this method is not ideal, and it is difficult to meet the expected water quality requirements.
