Assembled membrane bioreactor

Abstract

The invention discloses an assembled membrane bioreactor. The membrane bioreactor is formed by splicing multiple functional tank bodies communicated through a pipeline, wherein each functional tank body comprises a regulating pool functional tank body, an aerobic pool functional tank body, an anoxic pool functional tank body, and a functional tank body used as a control room; the aerobic pool functional tank bodies and the anoxic pool functional tank bodies are orderly and alternatively arranged in a matrix way. The membrane bioreactor disclosed by the invention is formed by splicing the multiple functional tank bodies, and the number of the aerobic pool functional tank body or the anoxic pool functional tank body can be properly added or reduced and the arrangement way of the aerobic pool functional tank bodies or the anoxic pool functional tank bodies can be changed according to actual demand and water depth demand of the engineering, thereby realizing the regulation of sewage handling capacity, and the field installation is convenient, and the transportation is convenient; a multi-layer membrane component is used in the membrane bioreactor, compared with a single-layer membrane component with the same membrane element number, the floor area of the membrane component is greatly reduced in the premise of guaranteeing the effluent effect; the floor area is reduced by 50%, an aeration rate is reduced by 36%, and the energy consumption and the economic cost are effectively saved.

Description

technical field [0001] The invention relates to a membrane bioreactor, in particular to an assembled membrane bioreactor, which belongs to the technical field of sewage treatment. Background technique [0002] In recent years, the sewage treatment system has transformed from a large-scale centralized system to a small and medium-sized decentralized system, forming a layout of "mainly large-scale and complementary small and medium-sized" in line with my country's national conditions and development situation. This provides a new opportunity for the application and development of the equipment structure of sewage treatment structures. Among them, membrane bioreactor, as a new and efficient sewage treatment device, has been widely used in the treatment of various industrial wastewater such as chemical industry, pharmaceuticals, textile printing and dyeing, as well as municipal domestic sewage. It integrates the traditional sewage biological treatment technology - activated slu...

Problems solved by technology

[0003] At present, sewage treatment equipment mostly adopts a rectangular parallelepiped or tank-shaped structure, which has disadvantages such as large footprint, waste of energy consumption, long custom manufacturing cycle, non-standardized equipment, and limited transportation, and cannot adapt to large-scale applications in the current market.
