摘要
制革废水具有产生量大、污染物种类多、成分复杂、含重金属等特点,一直是水环境监管的重点。对制革生产工序及废水产排特征进行梳理,通过调研和梳理制革企业排污许可证信息,对目前业内主流的水污染防治技术进行汇总分析,并按照原辅材料替代技术、过程控制技术、末端治理技术对行业主流水污染防治技术进行分类总结,其中,对过程控制技术按污染防治目标污染物进行分类总结,对末端治理技术按废水分质处理要求进行分类总结。基于不同类型制革企业水污染全过程防治需求,推荐16套技术组合方案。最后,结合技术发展情况,对制革工业水污染全过程防治技术发展趋势进行展望,提出强化制革废水分质处理、强化清洁生产技术的研发推广、推进制革企业入园等建议,以期提升行业水污染全过程防治水平和绿色发展水平,助力“十四五”深入打好污染防治攻坚战。
Tannery wastewater has the characteristics of large amount of production,various types of pollutants,complex composition,and containing heavy metals,and has always been the focus of water environment supervision.The tannery production process and the characteristics of wastewater production and discharge were sorted out,and the mainstream water pollution prevention and control technologies in the industry were summarized according to the raw and auxiliary material substitution technology,process control technology,and end treatment technology.Among them,the process control technologies were classified based on target pollutants,and the end treatment technologies were classified according to the requirements of wastewater quality-specific treatment.Based on the various demands for water pollution prevention and control of tannery enterprises with different production processes and different discharge types,16 sets of technology portfolio were recommended.Finally,the development trend of water pollution prevention and control technologies of the tanning industry was prospected,and suggestions to strengthen the quality-specific treatment of tannery wastewater,strengthen the R&D and promotion of cleaner production technologies,and promote the entry of tannery enterprises into the industrial parks were put forward,with a view to improving the level of water pollution whole-process prevention and control and the green development of the industry,and helping to deepen the fight against pollution prevention and control battle during the 14th Five-Year Plan period.
