摘　　要：经过对虹吸滤池滤头堵塞物的分析,发现了一种新的堵塞滤头的生物———水螅。造成堵塞的原因主要有两个:长时间暖冬导致了滤池中水螅的暴发性生长;反冲强度不够,不能冲掉堵塞物。对堵塞后的滤头采用20%的盐酸浸泡后再用10%的次氯酸钠溶液冲洗可以去除粘附其上的堵塞物。By analyzing the clogs in the filter nozzle of siphon filter, a new aquatic organism-hydra is found. There are two reasons that cause the clogging：long period of warm winter results in sudden growth of hydra in the filter; insufficient backwash rate fails to flush away the clogs. The clogs attached on the filter nozzle can be removed by soaking the clogged filter nozzle in the 20% hydrochloric acid solution and then flushing it with 10% sodium hypochlorite solution.
