Study on pollution status and characteristics of black and odorous water in rural areas of Henan province
摘要:
基于农村黑臭水体总体分布情况、污染特征、成因等基础资料欠缺的问题,对河南省典型地区内的农村黑臭水体进行现场调研和采样分析,初步掌握农村黑臭水体污染现状和污染特征.河南省农村黑臭水体主要污染来源有农村生活、工业废水、农业种植、畜禽养殖、水产养殖等5类,采集的103个黑臭水体水样中农村生活污染所占比例最大(57%),5个典型地区的黑臭污染程度由大到小依次为南阳淅川县,商丘虞城县,焦作博爱县,周口扶沟县,驻马店正阳县.采用相关性分析、主成分分析等方法对监测的指标进行分析,结果显示农村黑臭水体中ORP,DO,NH3-N,TP,COD显著性相关,与主成分高度相关的理化指标是NH3-N,TP,COD,BOD5,表明农村黑臭水体主要的污染因子是NH3-N,TP,COD,农村黑臭水体主要污染问题是有机物含量超标和富营养化.
Based on the lack of basic data on the overall distribution,pollution characteristics and causes of rural black and odorous water bodies,the field investigation and sampling analysis of rural black and odorous water bodies in typical areas of Henan province were carried out,and the pollution status and characteristics of rural black and odorous water bodies were preliminarily grasped.The main pollution sources of black and odorous water bodies in rural areas of Henan province are rural life,industrial waste water,agricultural planting,livestock and poultry breeding,and aquaculture pollution.Among the 103 black and odorous water samples collected,rural life pollution accounts for the largest proportion,accounting for 57%.The pollution degree of black and odor water bodies in the five regions decreased as follows:Nanyang Xichuan County,Shangqiu Yucheng County,Jiaozuo Boai County,Zhoukou Fugou County,Zhumadian Zhengyang County.Correlation analysis,principal component analysis and other methods were used to analyze the monitored indexes.The results showed that ORP,DO,NH3-N,TP and COD in rural black and odorous water bodies were significantly correlated.The physicochemical indexes highly correlated with principal components were NH3-N,TP,COD and BOD5.The results show that the main pollution factors of rural black and odorous water bodies are NH3-N,TP and COD,and the main pollution problems of rural black and odorous water bodies are excessive organic matter content and eutrophication.
