| Abstract: | In this paper,the methods of single pollutant index and multiple pollutant indexes are used to make an assessment of water quality of Nenjiang river in Qiqihar section.The results show that the biggest single pollutant index is chemical oxygen consumption(COD),and the water contamination can be classified as Grade 4 and Grade 5;The main pollutants are organic substances,and the overall water contamination can be classified as Grade 2 and Grade 3.There're some variations of COD pollutant index in different time sections,and the water contamination can be classified as Grade 4 and Grade 5.The water quality in the period from January to March,and December is good,and the water quality from April to May is the poorest. |
