摘要
为了给东北三省工业废水排放与污水农用的环境监控提供参考,选取产业结构调整前后的1999年和2005年两个典型年份的六价铬C(rⅥ)和化学需氧量COD这两个污染指标,对东北三省主要行业废水排放情况进行研究,从不同年份、不同区域(辽宁省、吉林省和黑龙江省)和不同行业三个角度对每一种污染指标的行业分布情况进行分析比较。结果表明,2005年废水中Cr(Ⅵ)和COD的排放量均明显低于1999年。Cr(Ⅵ)在1999年以辽宁省排放最多,主要排放行业为黑色金属冶炼及压延加工业和皮革毛皮羽绒及其制品业;在2005年以吉林省排放最多,主要排放行业为化学原料及化学品制造业。COD在1999年和2005年均以辽宁省排放最多,主要排放行业均为造纸与纸制品。
Characteristics of Cr（Ⅵ） and COD from different industrial sectors in the Northeast provinces of China in 1999 and 2005 were studi ed. Cr（Ⅵ） and COD were compared among different years, different sectors and also different areas, respectively. The results showed that the discharge of Cr（Ⅵ） and COD was obviously lower in 1999 than that in 2005. As for Cr（Ⅵ）, in 1999, the main discharge area was Liaoning province, the main sectors were smelting and pressing of ferrous metals and leather, furs, down and related products, while, in 2005, which were in Jilin province and at raw chemical materials and chemical products, respeetively. As for COD, both in 1999 and 2005, it was also high in Liaoning province, mainly from papermaking and paper products. The abovementioned analysis will provide reference for environmental management of industrial wastewater discharges and wastewater irrigation in the Northeast provinces of China.
