Efficient anaerobic granular sludge bed membrane bioreactor capable of self-supplying energy and operation method

Abstract

The invention discloses an efficient anaerobic granular sludge bed membrane bioreactor capable of self-supplying energy and an operation method, the membrane bioreactor comprises a main reaction column, settling chambers and a circulating pipeline. The main reaction column internally comprises anaerobic granular sludge and a hollow fiber membrane, the settling chambers comprise a pH electrode, anORP electrode, a DO electrode and a liquid level controller, a circulating magnetic pump, a rotor flow meter and a water inlet are mounted on the circulating pipeline. Continuous water inlet is conducted through a water inlet peristaltic pump, water outlet is controlled by the liquid level controller, and intermittent water inlet is performed. The efficient anaerobic granular sludge bed membrane bioreactor has the advantages that organic matters can be effectively recycled in sewage treatment, and the energy self-supplying of the whole membrane bioreactor is realized. The matched operation method can effectively reduce membrane pollution when the stability of the anaerobic granular sludge is maintained.

Description

technical field [0001] The invention belongs to the field of sewage treatment and resource utilization, and in particular relates to a high-efficiency anaerobic granular sludge bed membrane bioreactor capable of self-supplying energy consumption and an operating method. Background technique [0002] As a natural member of the "green family", the sewage treatment industry is drifting away from the concept of sustainable development. On the one hand, urban sewage treatment is a high-energy-consuming industry, and 60% of the energy consumption is consumed by blowers. At present, the average power consumption of sewage treatment plants in my country is 0.292kW·h / m 3 , more than 13% of sewage plants consume more than 0.48kW·h / m 3 , Even in the United States, the power consumption of its urban sewage treatment accounts for more than 3% of the total power consumption. On the other hand, urban sewage, as an important carrier of resource recycling, has huge potential energy and ne...
