摘　　要：在河蟹循环水养殖模式中,进行4种不同净化工艺对池塘养殖尾水净化效果的比较研究。工艺1以水生植物为主体进行净化;工艺2以水生动、植物进行多极净化;工艺3以浮萍和金鱼藻等进行净化;工艺4以微生态制剂和金鱼藻等进行净化。分别计算各净化区的污染物净化总量和单位净化面积的净化强度。结果表明,4种不同净化工艺对排入的池塘养殖尾水营养盐均有较好的吸收效果。不同的净化工艺对NH3-N、TN、TP和CODMn的去除能力表现出一定差异。工艺3对池塘养殖尾水中NH3-N、TN和TP的去除效果相对较好,对池塘养殖尾水中氮磷的净化效率相对优于其他3种净化工艺。This research compared four different nutrient uptake from the wastewater of fishpond under the aquaculture circulation mode of Eriocheir Sinensis H. milne-Edwards. The main body of the first technology for purification was aquatic plants, the second was aquatic animals and plants, the third was duckweed and goldfish algae,the fourth was probiotics and goldfish algae, calculating the purify amount of pollutant and the unit of purifying area intensity in the every zone. The results showed that there were certain nutrient uptake from the four different technologice, but there were some differences in removal capacity of NH3-N,TN,TP and CODMn.The best removal capacity effect of NH3-N,TN and TP was the third, so the purification efficiency of TN and TP of the third was better than the others.
