摘要
制革污水在水温为0℃—10℃的低温条件下,利用生物接触氧化法进行污水处理。试验结果表明,只要生物接触氧化池中的水温不低于4℃时,适当增大供氧量,就无需进行保温、加温。COD、BOD的去除率仍能保持较高水平。
The wastewater of tannery was treated by biological contact oxidation when the temperature of the wastewater was 0℃—10℃. The results of experiments indicated that if the temperature of the wastewater in the biological contact oxidation pond wasn′t below 4℃, the proportions of COD cr and BOD 5 removing remain hight levels by increasing the quarlity of oxygen supply.
