| 摘 要： | 隐孢子虫是常见的球状寄生虫。接触含有隐孢子虫卵囊的水体可致隐孢子虫病,主要的临床表现为腹泻,严重者可致死。游泳池是主要的传播场所。采用容积为5 500 L的游泳池,进行隐孢子虫卵囊替代物的修复模拟实验,研究在游泳池条件下絮凝沙滤技术对直径为4.5μm隐孢子虫卵囊替代物的去除效果。实验结果表明,氯化铝剂量为0.1 mg/L,沙滤料高度为30 cm,内循环流速为11.5 L/min,对隐孢子虫卵囊替代物去除率在90%以上。该技术对浊度具有较好的处理效果,当进水浊度降低且接近于出水浊度时,系统进入稳定运行阶段,对虫卵囊替代物去除率可以达到96%。

| Abstract: | Cryptosporidium species are the most common cause of gastrointestinal illness,associated with surface water.Full water-body contact recreations including swimming have posed a risk to the consumer inadvertently ingesting contaminated water.This research shows the effect of using coagulant to improve the efficiency of removing Cryptosporidium(simulated by microspheres) with sand filters in swimming pool applications.Experiments were carried out to examine the performance of filtration as an immediate remediation technique.Coagulation before filtration was able to improve removals to greater than 90% in a single pass.It could achieve 96% removal in stable state,when influent turbidity decreased to the value of effluent turbidity. |
