Problems solved by technology

[0011] The process occupies a large area, has many structures, and is equipped with many electromechanical equipment, high energy consumption, and complicated management and maintenance; in addition, the sequencing batch activated sludge process (SBR) and CASS process cannot continuously enter and exit water
However, although the biological contact oxidation method, biological aerated filter and membrane bioreactor (MBR) occupy a small area, they involve cleaning and replacement of fillers and membranes, high investment and operation costs, and complicated operation and maintenance.

[0054] In the biological reaction zone 21, a poro...

Embodiment 2

[0063] Based on the MSBBR sewage treatment system in the first embodiment, a complete sewage treatment process is formed, and the sewage treatment process comprises the following steps:

[0064] (1) Domestic sewage with a COD of 350-500mg / L and a BOD of 150-250mg / L is collected through pipelines, and suspended solids with a diameter greater than 3mm are removed through a grid;

[0065] (2) The domestic sewage treated by the grid flows into the regulating tank by itself, and the water quality and quantity are balanced to make the pH 6;

[0066] (3) Pump the adjusted domestic sewage into the MSBBR sewage treatment system to fully mix the domestic sewage with the activated sludge and polymer biological filler in the biological reaction zone of the MSBBR sewage treatment system, and adjust the exposure ratio of the biological reaction zone to 4:3, carry out anaerobic, facultative and aerobic treatment in a cycle to obtain supernatant and sludge; When the supernatant reaches the r...

Embodiment 3

[0073] Based on the MSBBR sewage treatment system in the first embodiment, a complete sewage treatment process is formed, and the sewage treatment process comprises the following steps:
