摘　　要：随着国家对环境保护的重视,废水的综合利用和水资源的循环利用已成为研究热点,特别是高耗水的无机硅化物生产行业,生产废水的排放问题一直是国内外生产企业未能解决的难题。简述了无机硅化物生产工艺中的废水来源、现有处理方法及存在的问题,介绍了一种无机硅废水处理新技术,通过三级沉降除杂、二次提浓、精滤及蒸汽再压缩技术(Mechanical Vapor Recompression,MVR)蒸发,实现了对无机硅化物生产过程中废水的综合利用,符合绿色化学的发展。无机硅废水处理新技术能提高资源利用率、降低企业成本、减少环境污染。With the increasing emphasis on environmental protection and the increasingly prominent issues of water scarcity and pollution,the comprehensive utilization of wastewater and the recycling of water resources have become research hotspots.This is especially so in the high water consumption inorganic silicide production industry,where the discharge of production wastewater has always been a problem that domestic and foreign production companies have not been able to solve.The treatment of inorganic silicon wastewater is also an important component of safety of the water environment.This article briefly introduces the sources,existing treatment methods,and existing problems of wastewater from the production process of inorganic silicon.A new wastewater treatment technology is introduced,which achieves comprehensive utilization of wastewater in the production process of inorganic silicon through three-stage sedimentation for impurities removal,secondary reconcentration,fine filtration,and MVR evaporation technology,in line with the development of green chemistry.This new processing technology can improve resource utilization,lower corporate costs,and reduce environmental pollution.
