摘要
在2021年12月9日至13日期间,针对龙马潭区各镇、街62个池塘养殖水体的出水口位置进行了水样采集。对悬浮物质、pH值、化学需氧量(COD)、五日生化需氧量(BOD_(5))、锌、铜、总磷、总氮、硫化物、总余氯等生化指标进行了测定,并按照《淡水池塘养殖水排放要求》(SC/T 9101—2007)二级标准进行了比对。测定结果表明,62个点位所测指标中悬浮物超标率为4.84%,COD超标率为50%,BOD_(5)超标率为17.74%,总磷超标率为4.84%,总氮超标率为12.9%,铜、锌、硫化物均未检出。通过对龙马潭区池塘养殖水体水质质量的分析,探讨了池塘养殖中存在的问题和应对对策,以指导该区域的渔业生产。
From December 9 to 13,2021,water samples were collected from the water outlets of 62 ponds in various towns and streets of Longmatan District.The biochemical indexes of suspended substances,pH value,chemical oxygen demand(COD),five-day biochemical oxygen demand(BOD_(5)),zinc,copper,total phosphorus,total nitrogen,sulfide and total residual chlorine were determined,and compared according to the(SC/T 9101-2007)secondary standard of<Discharge Requirements for freshwater Pond Aquaculture Water>.The results showed that the exceedance rate of suspended solids was 4.84%,COD was 50%,BOD_(5)was 17.74%,total phosphorus was 4.84%,total nitrogen was 12.9%,and copper,zinc and sulfide were not detected in 62 points.Based on the analysis of water quality of pond aquaculture in Longmatan District,the existing problems and countermeasures in pond aquaculture are discussed,so as to guide the fishery production in this area.
