洪湖新堤干渠水质及污染源调查与分析

Questionnaire Survey about the Water Quality and Source of Pollution in Xindi Canal of Honghu Lake

摘要: 针对洪湖新堤干渠的水质调查实验，我们主要采用国标法测量水体中氨氮，总氮，总磷，COD这四个指标，并在后期的数据分析中采用单因子分析法，结合水质综合评价标准对上述四个指标逐个分析，发现洪湖新堤干渠水质为III类，而且总氮和总磷含量明显偏高，通过实地调查我们发现水体污染和当地支柱产业——水产养殖有着密切的联系。基于各项调查及实验，提出了治理水污染的相关建议。

Abstract: Due to the survey of water quality in Xindi Canal of Honghu Lake, we used the GB method to meas-ure four types of data which were NH3-N, TN, TP, COD, and single factor analysis method was used in the later data analysis. Combining with the GB3838-2002, we analyzed the four types of data and found that the level of water quality in Xindi Canal of Honghu Lake is Class III. By the local investiga-tion, we found that the reason of water pollution is related to aquaculture which is the local pillar industry. The water protected advices were proposed based on the survey and the experiments data.
