复合式生物处理技术处理印染废水实验研究

Study on compound bio-reactor technology in treating dying wastewater

复合式生物处理技术将生物悬浮生长的活性污泥工艺和固定生长的生物膜工艺有机的结合起来,发挥了悬浮生长法效率高和固定生长法适宜性强和稳定性好的优点,提高了生物量,从而有效地提高生物反应器的容积利用效率,使其在高效率和高稳定性条件下运行.采用复合式水解酸化反应器和复合式好氧生物反应器处理印染废水,研究结果表明,水解酸化反应器可以显著改善废水的可生化性.经过8h水解酸化后接8h复合式好氧生物处理后,系统出水可以达标排放.

Compound biological treatment technology combined the suspended growth activated sludge process and fixed growth biofilm process, has the advantages of both the high efficiency of suspended growth and the good adaptability and stabilization of fixed growth. The biological amount is increased the volume utilization efficiency of the bioreactor, make it possible to be operated with high efficiency and stabilization. Compound hydrolysis acidification reactor and compound aerobic bioreactor were used to treat dying wastewater in this paper, the results showed that the hydrolysis acidification reactor could improve the bio-degradation ability of wastewater. The effluent of the system could meet the discharging standard through 8 hours of hydrolysis acidification followed by 8 hours of compound aerobic biological treatment.
