Deep bed multiplication MBBR for urban sewage treatment

Abstract

The invention discloses a deep bed multiplication MBBR for urban sewage treatment. The deep bed multiplication MBBR comprises a regulating tank, an anaerobic tank, an anoxic tank and a first aerobic tank which are arranged in sequence, and further comprises a second aerobic tank which is arranged on one sides of the regulating tank, the anaerobic tank, the anoxic tank and the first aerobic tank and separately communicates with the regulating tank, the anoxic tank and the first aerobic tank, wherein an inclined tube sedimentation tank, a filter tank and a sludge tank are arranged on the other sides of the second aerobic tank, and the inclined tube sedimentation tank is positioned between the filter tank and the sludge tank. Through combined usage of a labyrinth structural design, the regulating tank, the anaerobic tank, the anoxic tank, the first aerobic tank, the second aerobic tank, the inclined tube sedimentation tank, the filter tank and the like are organically combined together, so the integrity and coordination of a process are highlighted, an occupied area for sewage station construction and a process pipeline installation work amount are reduced, and investment cost is saved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and more specifically relates to a deep-bed multiplication MBBR reactor for urban sewage treatment. Background technique [0002] According to the statistics of E20 Research Institute, the treatment rate of sewage in cities and counties has exceeded 90%, but the treatment rate of sewage in established towns is only 30%, and the treatment rate of sewage in villages is less than 20%. The main battlefield of sewage treatment in the future will be from cities to towns transfer. In recent years, the national rural sewage treatment market is expected to be gradually released, and the total investment from construction to operation will reach 140 billion yuan. [0003] Due to factors such as scattered regions and high population density, there are still more than 100 million sewage households in my country that have not been effectively treated. According to media surveys, the embarrassing reality of "...

[0002] According to the statistics of E20 Research Institute, the treatment rate of sewage in cities and counties has exceeded 90%, but the treatment rate of sewage in established towns is only 30%, and the treatment rate of sewage in villages is less than 20%. The main battlefield of sewage treatment in the future will be from cities to towns transfer

At present, since the management and responsibility subjects of rural sewage treatment have not been clarified in the top-level design, there are many shortcomings to be made up in various areas such as billing methods and takeover responsibilities.
