摘要:湘江、資江、沅江、澧水和洞庭湖是湖南省主要的飲用水源和納污水體。城市化進程的加快、工業(yè)結(jié)構(gòu)的落后導(dǎo)致這些水域出現(xiàn)了一系列環(huán)境問題。為了解湖南省水域底泥污染現(xiàn)狀,對省內(nèi)5大水域底泥進行取樣,測試底泥樣品的物理參數(shù)(pH、含水率)、營養(yǎng)參數(shù)(有機質(zhì)、TCOD、總氮、總磷)和重金屬(砷、鎘、鉻、銅、鎳、鉛、鋅)含量。結(jié)果顯示,湖南省水域的底泥pH在6.64~8.66之間,含水率為22.5%~41.0%,有機質(zhì)含量為24.0~137.2 g/kg。采用單項指數(shù)法分析底泥重金屬沿程空間分布特征發(fā)現(xiàn),底泥重金屬污染程度在各水域表現(xiàn)出較大的差異,大多數(shù)采樣點的污染指數(shù)均小于1,污染評價等級屬于清潔。然而金屬Cd在澧水、沅江、資江、湘江和洞庭湖的平均含量分別為1.16、0.53、1.47、2.34和3.57 mg/kg。湘江和洞庭湖水域中Cd達到中度污染水平,其中洞庭湖水域的富豐肥業(yè)采樣點Cd含量為標(biāo)準值的17.72 倍,屬于高度污染水平。綜上,大多數(shù)采樣點的底泥中有機質(zhì)含量都屬于中低水平,底泥中氮、磷含量豐富,整體狀況良好。除Cd以外的被測金屬在各采樣點均屬于清潔或低污染水平,而Cd污染在各水域差異較大。在綜合分析底泥物理性參數(shù)、營養(yǎng)參數(shù)和重金屬含量的基礎(chǔ)上,提出了針對湖南省污染底泥的資源化途徑。
Abstract:The main drinking water sources and receiving waters in Hunan Province include Xiang River, Zi River, Yuan River, Li River and Dongting Lake. The rapid urbanization and unreasonable industrial structure lead to a series of environmental problems in these water areas. To understand the current situation of sediment pollution in the water areas of Hunan Province, this paper sampled sediments in five major water areas in the province, and physical parameters (pH, moisture content), nutritional parameters (organic matter, TCOD, total nitrogen, total phosphorus) and heavy metals (arsenic, cadmium, chromium, copper, nickel, lead, zinc) content of the sediment samples were tested. The pH of the sediment was between 6.64 and 8.66, the moisture content was between 22.5% and 41.0%, and the organic matter content was between 24.0 g/kg and 137.2 g/kg. The spatial distribution of heavy metals in sediment was analyzed by single index method. The heavy metal pollution degree of sediment showed great difference in different water areas. The pollution index of most sampling sites was less than 1, and the pollution evaluation level was clean. However, the average contents of Cd in Li River, Yuan River, Zi River, Xiang River and Dongting Lake were 1.16 mg/kg, 0.53 mg/kg, 1.47 mg/kg, 2.34 mg/kg and 3.57 mg/kg. Cadmium in Xiang River and Dongting Lake reached moderate pollution level, and the content of Cd in the sampling site of Fufeng Fertilizer Company in Dongting Lake was 17.72 times higher than the standard value, which belonged to high pollution level. In summary, the organic matter content in the sediment of most sampling sites was medium or low level, and the sediment was rich in nitrogen and phosphorus, which is in good overall condition. The pollution level of the measured metal at each sampling site was clean or low pollution level, but Cd pollution varied greatly in different water areas. Based on the comprehensive analysis of the physical parameters, nutrient parameters and heavy metal content of the sediment, the paper proposed a resource utilization approach for polluted sediment in Hunan Province.
