| 摘 要： | 以医院排放的高浓度含氰废水为研究对象,采用"硫酸亚铁+曝气"初级化学处理和ClO2二级深度氧化处理相结合的处理模式,不仅使含氰废水实现无毒化处理,而且使高浓度含氰废水实现资源化回收利用.试验表明,处理后的废水中CN-浓度达到国家排放标准GB8978-1996中的一级标准,为医院高浓度含氰废水的治理提供了一种新的方法.

| Abstract: | A combining process consisting of primary chemical treatment of iron vitriol-diffuse and secondary deep oxidation of chlorine dioxide was adopted in treating wastewater containing high concentration cyanogens from hospitals.After treatment, the wastewater containing cyanogens was not only nonpoisonous, but could be recycled and reused. Results obtained from the test show that the concentration of CN - reaches the first order of effluent discharge standard (GB8978-98) and a new method to treat wastewater containing high concentration cyanogens from hospitals is provided. |
