Problems solved by technology

On the one hand, the secondary settling tank has continuous water inflow and continuous water outflow. Due to the flow of water, it will bring a certain amount of agitation, which will not only affect the natural settlement of the sludge, but also the settled sludge at the bottom of the secondary settling tank will also be affected by the water flow. On the other hand, the sludge deposited at the bottom of the secondary settling tank, under long-term anoxic conditions, the sludge will undergo denitrification, generate air bubbles in the water, and drive the bottom The sludge floats up, which will lead to an increase of suspended solids in the effluent of the system, and the water quality is not up to standard

Abstract

The invention discloses an A2O2+MBR (Membrane Bioreactor) treatment device, belongs to the field of environmental protection and the field of treating and recycling of sewage. The A2O2+MBR treatment device comprises a water inlet, an anaerobic tank, an anoxic pond, a microaerobic pond, an aerobic tank, a membrane pool, spherical packing, MBRR (Moving Bed Biofilm Reactor) packing, a water outlet pipe, an aeration device, a sludge returning pipe, a nitrification liquid refluxing pipe and a self-priming pump, wherein biological filter beds are arranged in the anaerobic tank and the anoxic pond; the spherical packing is accommodated in the biological filter beds; the MBRR packing is accommodated in the microaerobic pond and the aerobic tank; an MBR membrane component is arranged in the membrane pool; by using a separating technology of the membrane, the concentration of activated sludge is greatly improved, and hydraulic retention time and sludge retention time of the activated sludge are respectively controlled; by high-efficiency solid-liquid separation, the water quality of effluent is stable, the amount of residual sludge is small, the occupied area is small, refractory organic compounds are removed, and the defect that traditional activated sludge is easy to expand is overcome. The A2O2+MBR treatment device can be widely applied to the field of sludge treatment.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to the fields of sewage treatment, water resource filtration biological treatment and reuse. Background technique [0002] In the field of environmental protection, especially sewage treatment is an important link in today's urban and rural water supply and drainage projects. The renewal and upgrading of existing urban sewage treatment plants, especially water plants whose effluent water quality is difficult to meet the standard or the treatment flow has increased sharply and the area cannot be expanded; no drainage pipes Residential areas, tourist resorts, scenic spots, etc.; areas or places that require sewage reuse, such as hotels, car washes, airliners, and mobile toilets, all require sewage treatment equipment. The existing sewage treatment equipment processes include: A2O2 (i.e. anaerobic-anoxic-microoxic-aerobic activated sludge method), A1: anaerobic tank,...
