| 摘 要： | 2009年4—9月期间,对上海市奉贤区某凡纳滨对虾(Litopenaeus vannamei)养殖场池塘两个养殖周期中总有机碳(TOC)、高锰酸盐指数(CODMn)、和五日生化需氧量(BOD5)进行分析检测。结果显示:试验的两个周期中(4—7月、7—9月),14个池塘BOD5分别为(8.62±3.08)mg/L和(10.47±3.87)mg/L,CODMn为(13.09±3.98)mg/L和(16.16±6.07)mg/L,TOC为(17.60±5.91)mg/L和(20.32±6.07)mg/L。TOC/CODMn分别为(1.35±0.22)和(1.32±0.30);TOC/BOD5为2.10±0.44和2.08±0.63;BOD5/CODMn为0.66±0.13和0.65±0.11。TOC、CODMn和BOD5两两之间呈显著线性正相关,第一个养殖周期中:BOD5=0.4174TOC+1.2777,r=0.8022;CODMn=0.5616TOC+3.2091,r=0.8342;BOD5=0.6264CODMn+0.4209,r=0.8106。第二个养殖周期中:BOD5=0.4764TOC+0.7902,r=0.7480;CODMn=0.7941TOC+0.0237,r=0.7962;BOD5=0.568CODMn+1.2912,r=0.8920。结果表明,利用建立的TOC、CODMn和BOD5之间的相关方程,可进行各指标之间的相互换算,从而与不同的水质标准或其他相关研究进行对比,为凡纳滨对虾养殖池塘的水质管理和健康养殖提供指导。 |

| Abstract: | Organic contents in fourteen ponds of a Litopenaeus vannamei culturing farm in Fengxian District of Shanghai were investigated during two aquaculture cycles from April to September in 2009.Total organic carbon(TOC),Chemical oxygen demand(CODMn),and Biological oxygen demand(BOD5) were analyzed respectively.The results showed that BOD5 were(8.62±3.08)mg/L and(10.47±3.87)mg/L in the two cycles of April to July and July to September respectively,CODMn were(13.09±3.98)mg/L and(16.16±6.07)mg/L,while TOC were(17.60±5.91)mg/L and(20.32±6.07)mg/L.TOC/CODMn were 1.35±0.22 and 1.32±0.30,and TOC/BOD5 were 2.10±0.44 and 2.08±0.63,while BOD5/CODMn were 0.66±0.13 and 0.65±0.11.Significant relationships lied among the three water quality parameters.Linear regression equations and related coefficients were as follows.In cycle 1:BOD5=0.4174TOC+1.2777,r=0.8022.CODMn=0.5616TOC+3.2091,r=0.8342.BOD5=0.6264CODMn+0.4209,r=0.8106.In cycle 2:BOD5=0.4764TOC+0.7902,r=0.7480.CODMn=0.7941TOC+0.0237,r=0.7962.BOD5=0.568CODMn+1.2912,r=0.8920.The results showed that the equations established among TOC,COD and BOD5 could be used to calculate the other two parameters if anyone of them had been measured so that further comparison with some water quality standards or correlated researches could be carried out,which would benefit water quality management and healthy culturing of L.vannamei. |
