Abstract： |
This invention discloses an anaerobic/aerobic coupling airlift loop bioreactor and method for treating chemical fiber wastewater. In the column of the bioreactor there are an outer flow-guiding cylinder and an inner flow-guiding cylinder. The outer flow-guiding cylinder surrounds the inner flow-guiding cylinder. An outer gas distributor and an inner gas distributor are fixed at the bottom of the column. The bottom of the outer flow-guiding cylinder is sheathed with the outer gas distributor. The inner gas distributor is fixed at the inner bottom of the inner flow-guiding cylinder. The method utilizes the bioreactor for biochemical treatment of chemical fiber wastewater. Compressed air is introduced into the bioreactor so that the liquid in the flow-guiding cylinders moves upward, therefore large circulation is formed between the two flow-guiding cylinders, and anaerobic treatment and aerobic treatment are coupled. Wastewater treated can satisfy discharge standards. The method has such advantages as easy operation, convenient management, good anaerobic/aerobic effect, and good biochemical treatment effect, and is suitable for industrial application. |
