Abstract

The invention relates to the field of sewage reuse, and particularly relates to an integrated MBR (Membrane Bio-Reactor). The integrated MBR is divided into an anoxic area and an aerobic area by using a baffle structure, carbon fiber packing is hung in the anoxic area, and an aeration device and a membrane assembly are placed in the aerobic area; the volume ratio of the anoxic area to the aerobic area is 1:3. The integrated MBR has the characteristics that due to the adoption of an integrated reaction device, the mode of multi-section processing in a single biochemical environment is solved, and the land-occupied area is saved; according to the structure characteristics, sewage circularly flows between the anoxic area and the aerobic area under the action of aeration, and shows different water flow characteristics; the device can simultaneously and effectively perform nitrification and denitrification processes, so that the sludge return is saved, thereby reducing the capital expenditure and the operation cost, and under the condition that the overall sludge concentration is not changed, the sludge concentration of the anoxic area is increased, and the sludge concentration of the aerobic area is reduced, thereby effectively reducing the membrane pollution; a carbon source required by denitrification is supplemented in a mode of feeding water from the anoxic area, thereby saving the cost.

Description

technical field [0001] The invention relates to the field of sewage reuse, in particular to a device and process for strengthening denitrification and dephosphorization while reducing membrane pollution. Background technique [0002] Compared with traditional farming methods, intensive, high-density, recirculating water aquaculture requires relatively less land and water resources, and has great economic advantages. It has higher requirements for water quality reuse, especially for its denitrification and phosphorus removal. The existing reclaimed water reuse technology has fundamental problems such as large capital scale, high operating cost, and low system integration level, showing the status quo of "high efficiency without increasing production, energy saving without saving money". [0003] The application research of MBR in the field of wastewater treatment began in the 1960s. In 1966, Dormliver of the United States first used MBR for the research of wastewater treatm...
