炉渣强化活性污泥法对餐饮废水的处理

Activated Sludge Process with Cinder Treat the Restaurant Wastewater

本文就炉渣强化活性污泥法处理餐饮废水的工艺特性进行了实验研究。通过加入炉渣前后的对比试验,实验结果表明,在用了炉渣强化活性污泥法净化处理的餐饮废水,CODcr、NH4+-N、TP去除率都优于普通活性污泥法,活性污泥絮体结构和沉降性能明显改善。当水力停留时间为6h时,炉渣强化活性污泥法对餐饮废水中CODcr、NH4+-N、TP的去除率分别达85.3～91.2%、59.6～68.2%、80.2～87.8%,出水中CODcr、NH4+-N均达到《污水综合排放标准》(GB8978—1996)一级标准,且处理效果稳定。因此炉渣强化活性污泥法处理餐饮废水的的效果是相当好的。

The text have carried on experimental study on craft characteristic of restaurant wastewater treatment by activated sludge process with cinder.It is shown that,the removal rate of CODcr、NH4＋-N、TP of the treated restaurant wastewater by activated sludge process with cinder is better than the one with normal activated sludge.The structure of flock and the characteristic of sedimentation are distinctly improved.When the whole HRT is 6 hours,the removal rate of CODcr,NH4＋-N and TP are 85.3～91.2%、59.6～68.2%、80.2～87.8% respectively through experiments.CODcr and NH4＋-N in the effluent meet the primary standard of 《Complex Standard of Sewage Discharge》（GB8978—1996）,and the treated effect is stable.So this treatment is perfect to treated the restaurant wastewater.
