Problems solved by technology

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of drainage. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, medical treatment, and catering. According to the classification of sewage sources, sewage The treatment is generally divided into production sewage treatment or domestic sewage treatment, but the sewage treatment tanks for domestic sewage treatment in the current technology have low processing capacity, poor effluent quality, and a large area.

Abstract

The invention provides a sewage disposal tank integrating diversified processes of Orbal, bio-dopp, MBBR and MBR. The sewage disposal tank comprises a tank body, the tank body is internally provided with compartment plates which sequentially divide the tank body into an anaerobic zone, an anoxic zone, an aerobic zone, a sedimentation zone and a membrane filtration zone, water via holes are formedin the compartment plates, the tank body is provided with a water inlet and a water outlet, the water inlet is located in the anaerobic zone, and the water outlet is located in the membrane filtrationzone; the volume ratio of the anaerobic zone to the anoxic zone to the aerobic zone is (18-25):(25-35):(45-60), sewage in the aerobic zone flows back to the anaerobic zone through a sludge reflux pipe, and the membrane filtration zone is provided with an MBR membrane which is an MBR dynamic membrane, an MBR flat membrane or an MBR curtain membrane; carriers are arranged in the anaerobic zone, theanoxic zone and the aerobic zone respectively. The sewage disposal tank integrating diversified processes of Orbal, bio-dopp, MBBR and MBR has the advantages of being small in occupied area and highin disposal efficiency and effluent quality.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment tank which integrates Aubauer, biological multiplication, MBBR and MBR multiple processes. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of drainage. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, medical treatment, and catering. According to the classification of sewage sources, sewage The treatment is generally divided into production sewage treatment or domestic sewage treatment, but the sewage treatment tanks for domestic sewage treatment in the current technology have low treatment capacity, poor effluent quality, and occupy a large area. [0003] The Aubauer oxidation ditch process can be set up in the form of three ditches, which are outer ditch, middle ditch, and inner ditch. The...
