【摘要】：目前對(duì)河流水質(zhì)的研究主要集中在較大的河流、湖泊以及水體污染嚴(yán)重的河流,而對(duì)農(nóng)村小河流的研究較少。本論文選取位于江西省內(nèi)的十一條典型的農(nóng)村小河流,河流涉及區(qū)域有撫河流域、九江地區(qū)、贛州南部以及鄱陽(yáng)湖環(huán)湖區(qū)。按照《水和廢水監(jiān)測(cè)標(biāo)準(zhǔn)》中的檢測(cè)指標(biāo)及試驗(yàn)方法確定了九項(xiàng)水質(zhì)指標(biāo),并根據(jù)河流規(guī)模和采樣方法確定每條小河流的采樣斷面及采樣點(diǎn),然后對(duì)其進(jìn)行采樣并進(jìn)行實(shí)驗(yàn)得出所需要的數(shù)據(jù)。分析數(shù)據(jù)判斷農(nóng)村小河流水質(zhì)狀況,然后對(duì)引起水質(zhì)變化的原因作出解釋。最后結(jié)合江西農(nóng)村小河流特點(diǎn)以及引起水質(zhì)變化的原因,對(duì)被污染的小河流提出合理的治理意見(jiàn)及建議。研究結(jié)果表明:在所選擇的11條小河流中,從單項(xiàng)指標(biāo)分析,水質(zhì)狀況不容樂(lè)觀,特別是總氮、總磷含量偏高;但從綜合水質(zhì)指標(biāo)分析,水質(zhì)狀況良好:其中有四條小河流的水質(zhì)級(jí)別達(dá)到Ⅱ類(lèi)水,占到全部河流的36.4%,有六條小河流的水質(zhì)級(jí)別為Ⅲ類(lèi)水,占所選取河流的54.5%,有一條河流的水質(zhì)級(jí)別為Ⅳ類(lèi)水,占全部河流的9.1%。
[Abstract]:At present, the research on river water quality is mainly focused on larger rivers, lakes and rivers with serious water pollution, but less on small rivers in rural areas. In this paper, 11 typical small rural rivers in Jiangxi Province are selected. The rivers involved include Fuhe River Basin, Jiujiang region, South Ganzhou and Poyang Lake region. According to the water and wastewater monitoring standards, nine water quality indexes were determined, and the sampling sections and sampling points of each small river were determined according to the river scale and sampling method. Then it is sampled and tested to get the needed data. Analyze the data to judge the water quality of rural small rivers, and then explain the causes of water quality change. Finally, according to the characteristics of small rivers in rural areas of Jiangxi Province and the causes of water quality change, reasonable suggestions and suggestions are put forward for the polluted small rivers. The results show that the water quality of 11 selected small rivers is not optimistic, especially the total nitrogen and total phosphorus content is high, but from the comprehensive water quality index analysis, the water quality is not optimistic, especially the total nitrogen and total phosphorus content is on the high side, but from the comprehensive water quality index analysis, The water quality is good: four small rivers have water quality grades of class 鈪，
