| 摘 要： | 随着工厂化循环水养殖的不断发展,高浓度循环养殖废水对环境污染日益严重.为实现环境友好和资源节约,采用臭氧/生物活性炭对循环养殖废水进行深度处理中试研究.实验结果表明,臭氧化臭氧最佳投加量为4 mg/L,显著增强水体的可生化性,使TOC(总有机碳)/UV254(在波长为254 nm处的单位比色皿光程下的紫外吸光度)提高80%.臭氧/生物活性炭对循环养殖废水中的有机物和氨氮具有良好的去除效果.臭氧/生物活性炭对TOC、高锰酸盐指数和UV254的最终去除率比生物活性炭分别高11.9%、13.4%和6.5%.臭氧/生物活性炭和生物活性炭对氨氮的最终去除率分别为96.0%、90.7%.

| Abstract: | With the developing of recirculating aquaculture system (RAS), the high nutrition and organic substance contained aquaculture wastewater gave more pressure on pollution discharge control. The pilot experiments of advanced treatment of recirculating aquaculture wastewater were conducted by using the combined O3/BAC process. The effect of ozonation on biodegradability of wastewater was investigated, with the ozone dosage of 4 mg/L, TOC/UV254 ratio was increased by 80%. The treatment efficiency of O3/BAC and B... |
