为了了解排泥车排泥不彻底，造成淤泥沉积后，淤泥中的微生物、藻类及有机质是否对水处理以及饮用水水质造成影响，我们于九七年九月份对羊额水厂一期工程的沉淀池不同位置的淤泥作了微生物、藻类及有机质等指标的检测，检测项目及结果如表1所示。结果分析及讨论：一、微生物指
In order to understand the incomplete discharge of sludge from the mud dumps and the resulting sludge deposition, whether the microorganisms, algae and organic matter in the sludge have an impact on water treatment and drinking water quality, we conducted the first phase of the project for the sheep water plant in September 1997. Sludge at different positions in the sedimentation tank was used for the detection of indicators such as microorganisms, algae and organic matter. Test items and results are shown in Table 1. Analysis and Discussion of Results: 1. Microorganisms
