摘    要:为了解、监测和评价广西淡水池塘养殖过程中主要污染物产生、排放及其对环境的影响,于2007年10月~2008年7月,选择位于南宁市兴宁区三塘镇留肖村2户养殖户的各1口池塘,在1年的养殖周期内,于秋、冬、春、夏季节,分别采集池塘内、出水口、池塘水源水样,监测池塘养殖斑点叉尾鮰主要污染物化学耗氧量(COD)、氨氮、总氮、总磷]的排放情况,并通过计算其排污系数K值,测算广西淡水池塘养殖年污染物排放情况并评价其对水域环境的影响。结果表明,在1个养殖周期内,COD、氨氮、总氮、总磷的平均K值分别为182.62、2.32、7.68和0.55kg/t;据此测算在1年的养殖周期内,广西淡水池塘养殖排放的污染物数量分别为COD140263.2t、氨氮1764.0t、总氮5997.6t、总磷425.6t。

关 键 词:淡水池塘养殖  污染物  排污系数  环境影响  评价

Abstract:The experiment was conducted to study the production and emission of pollutants and their effects on aquiculture environment in freshwater pond.During October,2007 to July,2008,two ponds located in Santang Township,Xingning District of Nanning City,Guangxi were selected for monitoring and assessing in autumn,winter,spring and summer seasons of a year.The emission of major pollutants,viz.,COD,NH3-N,TN,TP in catfish pond aquaculture was measured in water samples collected from pond,outlet and main water source,and the coefficient k value of pollution emission was calculated to estimate the annual pollutant emission in freshwater pond culture and to evaluate its effects on aquatic environment.The results showed that during a culture cycle,the average k value of COD,NH3-N,TN and TP was 182.62,2.32,7.68 and 0.55 kg/t,and the amount of pollutant emission COD,NH3-N,TN and TP in freshwater pond culture in Guangxi reached 140263.2,1764.0,5997.6 and 425.6 t in a one-year culture cycle,respectively.
Keywords:pond culture  pollution coefficient  pollutant  environmental impact  evaluation
