摘要
针对低温市政污水有机物去除效果差的普遍问题,结合二段生物接触氧化法的工艺特点,探讨了其处理低温市政污水的可行性.应用实践表明,在污水温度为8～15℃的情况下,进水COD、BOD5和SS分别由475.49、251.69和298.67mg/L降至49.68、21.62和22mg/L,污染物去除率分别达到了89.6%、91.4%和92.6%,取得了较好的去除效果.
The feasibility of the treating with low-temperature municipal waste water by two-stage bio-contact oxidation process is discussed, according to the general problems of the low removal rate of low-temperature municipal waste water. The results of engineering application showed that the process had high contaminant removal rate and under the temperature of 8～15 ℃, the COD, BOD5 and SS of outlet were 49.68, 21.62 and 22 mg/L respectively,corresponding the inlet 475.49, 251.69 and 298.67 mg/L,the removal rates reached 89.6% ,91.4% and 92.6% respectively.
