Based on the survey of several leather enterprises, some technical and administrative problems about treatment of wastewater containing chromium and sulfide, and odorous gas control in leather enterprises were discussed.First, collection and treatment of waste water containing chromium and waste water containing sulfide were not yet unified, leading to impact on the follow-up waste water pretreatment and biochemical treatment.Some enterprises neglected the details in treatment of odorous gas from leather warehouse, leather workshop of wet processing, and sewage treatment facilities.In the end, targeted suggestions were proposed to solve the above problems, including unifying and standardizing the range of Cr, S waste water collection and pretreatment, strengthening the control of leather warehouse, workshop of wet processing and sewage treatment system.%通过对数家制革企业开展调查分析,探讨了制革企业在含铬、含硫废水分流处理和各生产环节臭气防治方面存在的若干技术与管理问题.首先,含铬废水和含硫废水收集与管理不规范统一致使后续废水预处理及生化处理受到影响;部分企业忽略了原皮存放及转运、皮革水场加工车间、污水处理设施等臭气产生环节的细节控制.最后提出针对性的对策与措施建议,包括统一规范含铬废水和含硫废水的收集与预处理范围,加强原皮仓库、水场和污水处理系统的恶臭全过程控制.
