摘要
概述了蚯蚓生态滤池的研究进展,介绍了蚯蚓生态滤池化学除磷的工艺流程和设备参数;由试验得出氯化铁(FeCl_3·6H_2O)是蚯蚓生态滤池化学除磷的合适药剂,并确定最经济投加量为50mg/L;在此条件下,研究了化学除磷小试滤池产生的污泥性质,包括污泥产率的变化、重金属含量、污泥的脱水性能、污泥的稳定化程度以及污泥的最终处置方法。
The research progress of the earthworm ecotypic filter were overviewed, and the craft flow and equipment parameters of the chemical method in phosphorus removal in the earthworm ecotypic filter were introduced; The experiment educed that the ferric chloride （FeCl3·6H2O） could be used as the fitting medicament in doing away with phosphorus in the earthworm ecotypic filter,and made sure that the most economical dose was 50mg/L;In this case,the characteristics of sludge from the small scale earthworm filter under the chemical method in doing away with phosphorus were studied,which included the sludge＇s production, heavy metals content, dehydration function, the stability and final treatment methods.
