Abstract

According to the characteristic of high concentration and non-biodegradation of industrial effluents, temperature and hydraulic retention time (HRT) was related to the effect of operation in the reactor, an experimental study on hydrolysis acidification process as a preprocessing method. Results: with acidification pretreatment process as a means of biological treatment is effective, the effect of acidification reactor was obvious when the temperature in the 25-28 degrees Celsius, for 12h HRT, at the same time, COD_cr removal was about 35%, acidification rate could reach 28.1%. The biochemical of effluent could also greatly improve from 0.25 to 0.4 of B/C.
