淡水池塘养殖尾水处理模式

Present Situation of Freshwater Pond Aquaculture Wastewater Treatment

简述了养殖尾水的危害,总结了目前池塘养殖尾水较为常见的处理模式,分别为池塘容纳量控制净化模式、原位净化模式和异位净化模式。控制容纳量的净化模式,可降低养殖污染的产生量,从根源上控制污染,达到净化目的;原位净化模式,通过物理、化学和生物净化方法,对水体进行净化,降低排放尾水中的污染物;异位净化模式摆脱了净化操作对养殖生物的影响,同时原位净化中的各种方法可以有效地在异位净化模式中使用,能实现对尾水更彻底地处理,异位净化的整体净化效果更具优势,更易达到减少水源污染、提高养殖产量的目标。指出,未来综合治理的异位净化模式将会是池塘养殖尾水治理的主流方法。

In this paper,the harmful effects of aquaculture wastewater are briefly described,and the common treatment modes of pond aquaculture wastewater are summarized,which are pond capacity control purification mode,in-situ purification mode and ectopic purification mode.The purification mode of controlling the capacity can reduce the production of aquaculture pollution,control pollution from the source,and achieve the purpose of purification.Using in-situ purification mode,the water is purified by physical,chemical and biological purification methods to reduce pollutants in discharged wastewater.The ectopic purification mode gets rid of the influence of the purification operation on the cultivation organisms,and the various methods used in the in-situ purification can be effectively used in the ectopic purification mode,which can achieve a more thorough treatment of the wastewater.The overall purification effect of ectopic purification is more advantageous,and it is easier to reduce water pollution and improve aquaculture output.Finally,this paper points out that the ectopic purification model of comprehensive treatment would be the mainstream method of wastewater treatment in pond culture in the future.
