For influent, under any condition, siphoning may form without enforcing automatically.2.4.2 第一次运行2.4.2 The 1st runing向配水槽注水，使进水虹吸管形成水封，关闭阀门(4)，进水虹吸管即形成虹吸开始工作，当滤池正常工作后，再打开阀门(4)。When influent siphon pipe is in water-sealed state, shut off valve (4), siphoning forms by itself, and when filter can run normally, valve (4) will be shut off.2.5海水原水池2.5 Sea water tank海水原水池为半地下水池，容积为1000m3，储存来自虹吸滤池处理后的海水。海水原水池尺寸为20000120004800。水池进水管为DN500玻璃钢管，并设置有DN500溢流水管。水池检修时采用移动排水泵抽排。Sea water tank is a half embedded tank with capacity of 1000m3，storing sea water from filter basin.
