近年来设置在沿海江湾内的网箱养殖场,由于海底累积着饵料的残渣和鱼类排出的粪便,污染着海水,遇到发生赤潮或异常高温时,鱼类常因缺氧而死亡。为了解决这个问题,在网箱的外部安装一个网状捕捉器收集鱼类粪便和残渣所产生的污染物质.送到净化水槽内沉淀回收,另外又把净化水槽内经过净化后的海水用泵打到网箱上面喷淋,在发生赤潮时
In recent years, cage fish farms installed in coastal rivers and lakes have been contaminated with seawater due to the accumulation of food residues and fish excrement on the seabed. In the event of occurrence of red tides or abnormally high temperatures, fish often die of lack of oxygen. In order to solve this problem, a net catcher is installed on the outside of the cage to collect contaminants from the excrement and residues of the fish, sent to the purification tank for sedimentation and recovery, and the purified seawater in the purification tank is pumped To the top of the cage spray, in the event of a red tide
