活性生物滤池对生活污水净化处理效果的观察

目的：研制一种有效、经济、工艺流程较为简单的生物处理技术,对污水进行净化处理。方法：使用一种活性瓷粒作为生物滤池的填料,在供足O2的条件下,对生活污水的有机物进行充分氧化分解,观察污水中CODCr,BOD5的净化效果。结果：经活性生物滤池处理后,污水的CODCr,由处理前的444．84mg/L下降至16．76mg/L,下降率为96．23％,BOD5由处理前的211．54mg/L下降至3．95mg/L,下降率为98．13％,明显地低于城市二级污水处理下排放的一级标准。结论：活性生物滤池对生活污水的净化效果好,经济,工艺,流程较为简单,可适用于城市生活污水的净化处理。

Effectiveness of Small-size Activated Bio-filter on Purification of Domestic Sewage

ve To research an effective, economic and simple biological treatment technology process for purification of sewage. Methods With the sufficient supplication of oxygen, the organic compounds in domestic sewage were sufficiently oxidized and decomposed in bio-filter using activated pottery granule as packing materials. CODCr and BOD5 reflecting the effectiveness of purification of sewage were determined. Results After the treatment by activated bio-filter, the levels of CODc, of treated sewage decreased from 444.86 mg/L to 16.76 mg/L with a de-crease rate of 96.23% , the levels of BOD, decreased from 211.54 mg/L to 3.95 mg/L with a decrease rate of 98. 13% . The levels of CODCr and BOD5 of treated sewage all were below the related values of grade I standand of discharge from secondary municipal sewage treatment plant. Conclusion The purification technology using activated bio-filter was effective, economic and simple, which could be widely applied to demestic sewage purification treatment.
