摘要
为了解“三池两坝”多级池塘对凡纳滨对虾工厂化海水养殖尾水的处理效果,以山东烟台某凡纳滨对虾工厂化养殖合作社为试验基地,在1个凡纳滨对虾养殖周期内,每周对养殖池、沉淀池、曝气池和生物处理池进行1次水质监测,共进行10次监测。结果表明:对虾养殖过程排放的养殖尾水呈重度富营养化,经“三池两坝”处理后的养殖尾水富营养化指数(E)平均值较处理前下降93.5%,共去除1个对虾养殖周期养殖尾水中污染物总量的57.5%,各监测项目平均去除率为DIP>DIN>TSS>TP>TN>COD。
In order to understand the treatment effect of“three ponds and two dams”as multi-stage process on the wastewater from Litopenaeus vannamei industrialized mariculture,a Litopenaeus vannamei industrialized mariculture cooperative in Yantai,Shandong Province was used as an experimental base.Within one culture cycle of Litopenaeus vannamei,the water quality of the culture ponds,sedimentation ponds,aeration ponds and biological treatment ponds were monitored once a week,and a total of ten monitoring measurements was conducted.The results showed that the wastewater discharged from the mariculture process was severely eutrophic.Moreover,the average value of the eutrophication index(E)of the wastewater decreased by 93.5%after the multistage treatment of“three ponds and two dams”compared with that before treatment.In addition,57.5%of the total amount of pollutants in the wastewater of one culture cycle was eliminated.The ranking of the average elimination rate of each monitoring parameter is:DIP>DIN>TSS>TP>TN>COD.
