池塘养殖尾水处理技术应用现状及改进措施

Application Status and Improvement Measures of Tail Water Treatment Technology in Pond Culture

池塘的高密度养殖方法造成大量的残饵与排泄物进入水体,导致养殖尾水污染问题日益严重。养殖尾水管理和循环使用,已成为制约中国水产养殖可持续发展的关键问题。文章深入分析了水产养殖尾水特性以及目前尾水处理过程中的物理、化工、生态等技术优劣势,总结了池塘养殖尾水处理技术应用中存在的问题,并提出了一系列改进的措施。

The high-density aquaculture method of ponds causes a large number of residual bait and excrement into the water,which leads to the increasingly serious water pollution of aquaculture tail.The management and recycling of aquaculture tail water has become a key issue restricting the sustainable development of aquaculture in China.In this paper,the characteristics of aquaculture tail water and the advantages and disadvantages of physics,chemical and ecological technologies in the current tail water treatment pro‐cess are deeply analyzed,and the problems existing in the application of pond aquaculture tail water treatment technology are sum‐marized,and a series of improvement measures are proposed.
