摘　　要：二硫氰基甲烷是一种高效、广谱杀菌剂，其生产废水毒害性大，不适于生化处理。设计并制作了一套处理工艺装置。采用降温回收废水中的二硫氰基甲烷——光解氧化——浓缩结晶脱除氯化钠——碱性氯化法除氰工艺。结果表明：光解氧化——碱性氯化法能有效去除废水中的有害物质，脱色效果显著。获得了处理出水达标的数据：色度〈50（倍）；SS≤70mg/L,BODs≤20mg/L;CODCr≤100mg/L;NH3^-N≤15mg/L;CN-≤0.5mg/L;pH=6-9.Methylene- （Bis）thiocyanate is a high efficient and extensive music disinfectant. His produce waste water is big poison by, not fitted biochemistry dispose of sewage. Designed and made an technology installation of waste water dispose. Introduce the technology with respect to lower the temperature reclaim raw methylene - （Bis） thiocyanate from waste water - - light decomposes Oxidize - - enriched and cryallized take off sodium chloride - -basification chlorinate method take off the cyanogen. The results were as： light decomposes oxidize - -basification chlorinate can effective take off pernious matter in the waste water decolour bring about a striking effect. The following data of come to standard for improving water were obtained： colour multiple of dilute 〈 50;SS≤70mg/L,BODs≤20mg/L;CODCr≤100mg/L;NH3^-N≤15mg/L;CN-≤0.5mg/L;pH=6-9.
