Problems solved by technology

Scholars at home and abroad have invested in this issue. At present, the methods for treating tobacco flake wastewater generally include physical and chemical methods, biochemical methods, and the combination of the two. However, these methods have some problems in the process of treating wastewater. Insufficient, on the one hand, the removal effect of nicotine is not significant; on the other hand, the treatment cost is high, and secondary pollution may occur

Abstract

The invention relates to a culture device and a rapid culture method of aerobic granular sludge capable of efficiently degrading nicotine. The device is composed of an SBAR reactor, a numerical control water bath kettle, an air compressor, a gas rotor flow meter, an electronic relay, and a sand core aeration head. The constructed SBAR reactor is used for culturing aerobic granular sludge for degrading nicotine, the temperature of the reactor is about 25 DEG C, and the initial pH value of inlet water is controlled to be about 7.0. In the culture process of the aerobic granular sludge, the nicotine degradation capacity and the COD degradation rate are gradually improved, the average particle size of the sludge is gradually increased, and the biological phase in the reactor also shows an evolution rule from low level to high level. In the process of treating tobacco sheet wastewater by using nicotine degrading bacteria, aerobic granular sludge for efficiently degrading nicotine is cultured and domesticated, and the operation of the SBAR reactor is combined to quickly remove nicotine, so that a good foundation is laid for the research of treating nicotine sheet wastewater by using microorganisms.

Description

technical field [0001] The invention relates to a cultivation device and a rapid cultivation method of aerobic granular sludge for efficiently degrading nicotine, and belongs to the technical field of high-concentration nicotine sewage biological treatment. Background technique [0002] Nicotine is the main chemically stable, refractory toxic and harmful organic pollutant in tobacco sheet production wastewater, and is very soluble in water. If nicotine in the wastewater is not completely degraded and discharged into the environment, it will affect the water ecosystem and The health of surrounding populations poses a serious threat. Studies have shown that the use of microorganisms to degrade nicotine is a low-cost, high-efficiency and low-impact nicotine treatment method. Therefore, screening and using highly efficient nicotine-degrading bacteria, rapidly constructing nicotine-degrading aerobic sludge particles, and improving the regulation mechanism of the wastewater biolo...
