对碱法制浆废水治理技术几个问题的浅议

摘 要 对以提高其耐化学性和耐热性我国造纸工业碱法制浆废水污染的防治，更加强调厂内清洁生产和水污染控制。特别指出，传统燃烧法碱回收加二级生化处理工艺是适合处理这类污水的技术路线；并就近年出现的几个有关问题加以讨论，提出了个人的看法。关键词 碱法制浆 废水 挖掘机械碱回收 二级生化处理Discussion o永安n the显微镜 Technical Issues of Wastewater Treatment of Alkaline PulpingYu Huifang(China National Beijing Contracti液压实验机主要用于金属ng and Engineering Institute for Light Industry, Beijing，100026)ABSTRACT The properties and treatment process of the wastewater of sulfate pulp mills in China ，as well as the treatment results are presented.
