Abstract

The invention relates to a double filler and self-cleaning anaerobic expanded bed bioreactor and in particular relates to an anaerobic expanded bed bioreactor. The anaerobic expanded bed bioreactor comprises a tank body, an upper cover, a sieve plate part, a back flush water distribution pipe part, a spiral deflector part, a three-phase separator and an expanded bed circular water distribution pipe part; the back flush water distribution pipe part comprises an upper spray nozzle, a back flush water distribution pipe and an upper support; the expanded bed circular water distribution pipe part comprises a spiral ejector, an expanded bed circular water distribution pipe and a lower spray nozzle. According to the anaerobic expanded bed bioreactor, organic matters in wastewater are degraded by adopting a heavy filler anaerobic expanded bed; suspended matters in the wastewater are filtered by adopting a lightweight filler fixed bed; a biofilm updating process is controlled by adjusting the circulating water flow rate of the expanded bed, and the negative influence of sharply fluctuation of water inlet flow rate on effluent quality of the anaerobic expanded bed bioreactor is avoided.

Description

technical field

[0001] The invention is a self-cleaning anaerobic expanded bed bioreactor with double packing, which relates to an anaerobic expanded bed bioreactor, in particular to a kind of anaerobic expanded bed with heavy packing and fixed bed with light packing at the same time. Anaerobic expanded bed bioreactor for wastewater. Background technique

[0002] Add solid granular fillers to the anaerobic expanded bed bioreactor. Commonly used fillers include quartz sand, ceramsite, etc. The anaerobic expanded bed bioreactor needs to use the method of effluent reflux to expand the packed bed in the reactor. The anaerobic reactor in which the filler particles in the packed bed are slightly loose, and the gap between the filler particles increases but still keeps in contact with each other is called an anaerobic expanded bed bioreactor.

[0003] The packed bed of the anaerobic expanded bed bioreactor has a high concentration of microorganisms, a high organic matter volume lo...
