摘　　要：为了处理和资源化利用池塘养殖废水,结合生物滤池和水上稻作技术,设计并构建了一种适合于水稻种植的水处理系统。系统运行试验结果表明:在水力负荷为0.29~0.58 m/d,气水比为2~4时都可以获得比较好的水处理效果。将池塘养殖有机结合形成的循环水养殖系统中,在水力负荷为0.58 m/d,气水比为2的条件下,系统对养殖废水中TAN、TN、TP和CODMn的去除率分别为33.75%~34.31%、59.21%~64.53%、68.43%~73.75%和71.66%~74.37%。与此同时,水处理系统获得7 127.01 kg/hm^2的水稻产量。由此实现养殖废水资源化利用,是一种可持续的水产养殖方式,可为我国渔农混作区池塘养殖废水的处理和循环利用提供一种新方法。A novel water treatment system suitable for rice planting was designed and constructed to treat and recycle wastewater from aquaculture pond. According to the performance results of the system,the treatment efficiency was optimal when the hydraulic load was 0. 29 - 0. 58 m / d and the gas water ratio was 2 - 4. The removal rates of the system on the TAN,TN,TP and CODMnfrom wastewater were 33. 75% - 34. 31%,59. 21% - 64. 53%,68. 43% - 73. 75% and71. 66% - 74. 37% respectively when the hydraulic loading was 0. 58 m / d and the gas water ratio was 2. Meanwhile,rice yield achieved 7127. 01 kg / hm2. Therefore,this water treatment system could efficiently purify and reuse the nutrition from the wastewater by the uptake of rice,which could thereby develop a new technology for pond aquaculture wastewater treatment and reuse in agriculture-aquaculture ecotone in China.
