摘要
炼油污水经生化处理后虽能达标排放 ,但仍对水体造成污染。若再经深度处理使水质达到地面水Ⅳ级标准 ,循环用于工业生产 ,则具有重大经济效益和环境效益。
Although the oil refining sewage treated by the secondary biochemical method can reach the standard of drain, it may still cause water body pollution. If further by the deep treatment, the water quality may reach the standard of the Ⅳ grade of surface water. Circulating use of such effluent in industrial production may create great economic and environmental benefits.
