| 摘 要： | 探讨了蛭石添加到活性污泥中来处理餐饮废水这一特殊水质时所起的作用.试验结果表明,蛭石活性污泥体系协同蛭石的吸附和污泥生化的作用,提高微生物的降解速率,缩短了污水在反应器中的停留时间.膨胀蛭石活性污泥体系在曝气2 h条件下出水CODCr浓度远远优于常规活性污泥体系曝气5 h后出水CODCr浓度.试验还表明,蛭石起到生物膜载体的作用,其与活性污泥结合成的絮体颗粒在改善污泥沉降性能,提高净化效果的同时,也增强了系统的稳定性.

| Abstract: | Tests are conducted to investigate the effect of vermiculite in restaurant wastewater treatment by activated sludge, The results show that the activated sludge system added with vermiculite can enhance the CODcr, removal rate and shorten HRT with its functions of absorption and bio- reaction. CODcr, value of effluent alter being treated fur 2h by activated sludge system with dilatable - vermiculite is found to be far lower than that being treated fur 5h by conventional activated sludge system. The results also show that vermiculite functions as biological membrane carrier and the flocculating particles combined with activated sludge can improve the setting characteristics of sludge, raise CODcr removal rate and strengthen the stability of the system. |
