在分析传统池塘养殖和工厂化养殖生态系统结构与功能缺陷的基础上,运用生态补偿和环境补偿原理对传统养殖池塘的结构、功能与过程进行了生态设计,并在实际生产条件下对新型封闭循环水集约化水产养殖池塘进行了性能测试。结果表明,封闭循环水集约化水产养殖池塘的结构有利于垂直混合增氧、集污和引污,具有持续高效地分离污染物的净水功能,水环境稳定利于水产动物生长,长期运行并不造成硝态氮、氨氮等的积累,可不洗塘、不肥水、不换水、不排水,达到废水零排放,对于传统池塘养殖生产方式转变和产业可持续发展具有重大意义。
Based on the analysis of the structure and function defects of the traditional pond culture and factory farming ecosystem, the ecological design of the structure, function and process of the traditional culture pond was carried out by using the principle of ecological compensation and environmental compensation. Under the actual production conditions, the new closed Circulating water intensive aquaculture ponds were tested for performance. The results showed that the enclosed aquaculture aquaculture pond structure is conducive to vertical mixing and aeration, sewage collection and decontamination, with a continuous and efficient separation of pollutants in the water purification function, the steady water environment conducive to aquatic animal growth, long-term operation is not Resulting in the accumulation of nitrate nitrogen, ammonia nitrogen, etc., can not wash the pond, no fertilizer, no water, no drainage, to achieve zero discharge of waste water, for the traditional pond farming production and industrial sustainable development is of great significance.
