摘要
以成都平原某废弃铅蓄电池污染场地为例,调查识别典型工业场地主要污染物空间分布特征和剖面迁移特征。结果表明:场地主要潜在Pb污染源有建筑垃圾、土壤及残留废水,潜在污染途径为大气降尘、含Pb废水排放;建筑垃圾中Pb、Cd、As等污染严重;场地内酸液暂存池和清洗池地表水中Pb、Cd超标严重,均为劣Ⅴ类;场地内及周边环境地下水中Cd、Cr污染较重;区内表层土壤中Pb、Cd污染严重,且呈面源性,距循环水池及酸液暂存池1.2 m处土壤中Pb含量远高于周边区域。
This paper investigated and identified the spatial distribution characteristics and profile migration of the main pollutants in typical industrial sites by taking a abandoned lead storage battery manufacturing site in Chengdu Plain as an example. The results showed that the main potential lead contamination sources in the site were form construction waste, soil and residual waste water. The potential pollution ways were from dust fall and Pb-containing waste water. Pb, Cd and As pollution were severe in construction waste. The content of Pb and Cd in surface water derived from temporary acid liquor storage pool and cleaning pool in the site badly exceeded the standards and the water quality was worse than grade Ⅴ. Cd and Cr pollution was serious in groundwater at the site and its surroundings. In the surface soil of the site, Pb and Cd pollution were rather serious, presenting non-point source feature. The content of Pb in the soil 1.2 m away from the recycled water pool and temporary acid liquor storage pool was much higher than that of in the surrounding area.
