摘要： 通过对辽宁省4种典型行业的工业废水理化与生物毒性指标的监测和评价,结果表明造纸和金属冶金行业废水的COD和SS污染物浓度超标严重,化学工业行业废水主要是COD浓度超标.造纸、石油焦化、金属冶金行业废水发光菌相对抑光率的毒性级别较高,多数处于中毒-剧毒之间,化学工业各生物毒性级别在低毒-中毒范围内.造纸行业废水的COD浓度和SS浓度与各生物毒性指标间的相关性极显著.石油焦化、化学工业行业废水中挥发酚浓度与各生物毒性指标间具有较好的相关性,金属冶金行业废水中COD浓度与生物毒性指标具有较好的相关性.

Abstract: The physico-chemical and biological toxicity in indices of the wastewater in 4 typical industries in Liaoning were monitored and assessed. The results indicated that both COD and SS concentration exceed greatly the prescribed standards for environmental protection in the effluent from paper-making and metallurgy industries, whereas mainly the COD exceeds the standard in the effluent from chemical industry. The relative opacity of luminescent bacteria showed that the grades of aquatic toxicity of the effluents from paper-making, petroleum/coking and metallurgy industries are high and most of them are between fatal and medium. But the biotoxicity grade of the effluent from chemical industry is in the low-medium range. It was found that there is a highly obvious correlation between COD/SS concentration and various biotoxicity indices in the effluent from paper-making industry, while that between volatile phenol and various biotoxicity indices is proper in the effluents from petroleum/coking and chemical industries. As to the effluent from metallurgy industry, the correlation between COD and biotoxicity indices is also proper.
