Abstract

The invention provides a method for treating domestic wastewater with a porous multilayer hollow PTFE-MBR membrane. The method comprises the steps that domestic wastewater is collected through a pipe network and then enters a wastewater treatment station, wherein gratings are arranged at the front end of the wastewater treatment station, and the gaps between the gratings is 5 mm; water out of the gratings automatically flows into an oil separation tank; water out of the oil separation tank enters a regulating tank; water out of the regulating tank is lifted to an anoxia tank through a submersible sewage pump, wherein the primary function of the anoxia tank is denitrification; water out of the anoxia tank automatically flows into an aerobic tank, wherein the aerobic tank performs the functions of making active sludge carry out aerobic respiration, further decomposing organic matter into inorganic matter and removing pollutants; water out of the aerobic tank automatically flows into a membrane bioreactor; water of the membrane bioreactor is sucked to a discharging tank through a self-priming pump and then discharged into a natural water body through a Parshall trough. According to the method, the occupied area is small, the technological process is short, the water quality of outlet water is stable, it is ensured that outlet water is clear and transparent, and high-quality produced water is obtained.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a method for treating domestic sewage by a porous multi-layer hollow PTFE-MBR membrane. Background technique [0002] The main process technologies of sewage treatment mainly include: biological treatment technology and natural treatment technology. After hundreds of years of human practice, it is internationally recognized that biological treatment has the best cost-effective ratio. Therefore, most sewage treatment plants in the world adopt biological treatment process. Sewage biological treatment is divided into two categories: anaerobic biological treatment and aerobic biological treatment. [0003] The efficiency of anaerobic biological treatment technology in degrading organic matter is limited, the effluent water quality is difficult to meet the requirements of this project, and it occupies a relatively large area, and the problem of waste gas collection...
