摘　　要：于2011~2012年,对广西沿海养殖池塘进行了大范围排污状况调查,调查范围涉及广西沿海三市主要池塘养殖区,共调查74个位次,其中北海市15位次,防城港市26位次,钦州市33位次;调查指标共12项,包括：悬浮物质、pH、CODMn、BOD5、Cu、Zn、无机氮、PO4-P（以P计）、硫化物（以S计）、总余氯、TN、TP。按照行业标准《海水养殖水排放要求》SC/T9103-2007对其10项指标的达标情况进行了计算：各项指标达标率排序为Cu=硫化物〉Zn〉悬浮物〉pH〉总余氯〉CODM〉BOD5〉无机氮〉PO4-P。各养殖模式中,南美白对虾池塘养殖模式污染指标超标率最高。但其TN和TP的高排污塘比例低于鱼类养殖模式和青蟹养殖模式。制定更全面的池塘养殖排污地方标准和针对广西池塘养殖模式的特征开展末端治理试验是目前的重点研究方向。In 2011 ~ 2012,we have a large-scale sewage survey of Guangxi coastal aquaculture ponds,covering three cities in Guangxi coastal pond aquaculture area,surveyed 74 ranking,including 15 ranking of Beihai City,26 ranking of Fangchenggang City,33 ranking of Qinzhou City; 12 survey indicators including： suspended matter,pH,chemical oxygen demand（ CODMn）,5th biochemical oxygen demand（ BOD5）,copper,zinc,inorganic nitrogen,active phosphate（ as P）,sulfide（ as S）,total residual chlorine,total nitrogen,total phosphorus. Mariculture water discharge requirements in accordance with industry standards SC / T9103- 2007 its ten indicators of compliance calculation： Sort indicators compliance rate for copper = sulfide Zn suspended solids pH total residual chlorine CODMn BOD5 inorganic nitrogen active phosphorus. Vannamei shrimp pond production model pollution indicators exceeded the highest rate of breeding patterns. However,the high sewage pond proportion of total nitrogen and total phosphorus below the fish breeding patterns and mud crab farming model. To develop a more comprehensive sewage pond culture local standards and to carry out the end of the treatment for pond culture mode of Guangxi characteristics test is the focus of current research directions.
