摘要
对穿透水厂但经有效灭活的桡足类进入供水管网后的分布规律进行了研究。选择了水力沿程点、二次水池(箱)、用户龙头点、死水管段等代表性点位,经过长达一年半的监测研究,总结出桡足类在供水管网中的基本分布规律:由于重力沉降作用,桡足类死体在供水管网中的密度分布主要受水流速度影响,总体上表现为距离水厂管道沿线越远,其密度越高;在死水管段大量沉积;二次水池(箱)对桡足类死体有截留作用。
The distributing rule of dead copepods organism in water supply network which come from treated water plant was studied. Different hydraulic conditions, user faucet, cistern of secondary water supply and tube which contain ＂dead water＂ were chosen as representative monitor points. The research lasted one and a half year. It shows that the factor influences the distribution of copepods most is the velocity of water flow in the network. Cistern of secondary water supply can head off copepods and make water clearer after it. For those tubes that contain ＂dead water＂, the amount of eopepods can accumulate to a large number.
