4 种不同净化工艺对池塘养殖尾水净化效果的比较研究 中文摘要 中文摘要 为了筛选高效养殖尾水净化模式，支撑养殖污染减排和循环水养殖技术的实 施和推广，在苏州市阳澄湖现代农业产业园进行了 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 物、植物进行多极净化，工艺 3 以漂泊植物（浮萍）和沉水植物（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。分别计算了各净化区的污染 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，但不同的净化工艺对 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它三种净 化工艺。 关键词：养殖尾水；净化工艺；净化效果 作 者：王国清 指导老师：蔡春芳 I 英文摘要 4 种不同净化工艺对池塘养殖尾水净化效果的比较研究 Comparison the Efficiency of Nutrient Uptake from Aquaculture Pond by Four Different Purification Technology Abstract Waterwater from aquaculture pond were decontaminated by four technics and the efficiency was compared in Yangchenhu Modern Agricultural Development Co. Ltd. The main body of the first technics for decomtamination was aquatic plants, the second was aquatic animals and plants, the third was floating plants (duckweed) and submerged plant (goldfish algae), the fourth was probiotics and submerged plant (goldfish algae). The amount of removed pollutants was calculated in the every zone. The results showed all of these four technics could romove pollutants efficiency, with the third technics had the highest capacity to remove NH3-N 、TN and TP.
