Bio-membrane reactor

Abstract

The invention relates to a bio-membrane reactor, and belongs to the field of wastewater treatment equipment. The bio-membrane reactor comprises a water inlet pump, a water inlet pipe and a water purification pool, and is characterized in that the water inlet pump is connected with the water inlet pipe; the water inlet pipe is connected with the water purification pool; a vibration filtering net isarranged inside the water purification pool; one end of the vibration filtering net is connected with a cleaning door and the like; the suspension cascade layering of bio-particles is realized; through the effects of microorganisms and inorganic catalysis, the purification effect on wastewater can be effectively realized. The bio-membrane reactor solves the problems that the oxygen content insidea membrane in the existing bio-membrane reactor is low, so that the most region inside the bio-membrane is in an anaerobic state; the specific gravity and the activity of aerobic microorganisms on the bio-membrane are inhibited; the adverse influence on the sewage degradation efficiency is caused.

Description

technical field [0001] The invention relates to a biofilm reactor, which belongs to the field of waste water treatment equipment. Background technique [0002] In recent years, with the rapid economic development, my country has also brought a series of environmental problems while pursuing GDP growth. Among them, the shortage of fresh water resources makes urban domestic sewage treatment technology particularly important. However, with the improvement of people's living standards, the content of nitrogen and phosphorus in urban domestic sewage increases, and the organic components are complex. The traditional biological sewage treatment technology has been unable to keep up with the pace, and the treatment effect is not good. The characteristics of high efficiency, less residual sludge production, and convenient operation and management have been rapidly developed, and have broad application prospects in sewage treatment. [0003] The so-called biofilm method refers to the...
