【摘要】 <正> 乳胶漆以水为介质,不含易挥发的有机溶剂,在生产和应用中大大减少了对环境的污染。然而,在清洗乳胶漆所用的设备和容器时,会产生含漆废水。这类废水带色、混浊,其中主要含细小的聚合物颗粒和颜料、填料颗粒,此外,还有少量的各种助剂。处理这类废水的关键是将固体颗粒与水分离,更多还原

【Abstract】 Two anionic polymer flocculants,HCD quaternary amine and SGtypes modified with starch wereused for the treatment of latexpaint waste water, which is fea-tured by less flocculant used,fastflocculation, better effectiveness,natural aggregation and less vo-lume of the flocculating structure,The waste water after treatmentis clear and colorless, transmissi-vity being 90 to 98%, and chemi-cal oxygen consumption beingreduced by 39 to 64%. The pHvalue, usage of flocculant andpaint content in waste water werediscussed and two flocculants,HCD-1 and SG-11 were compared.更多还原
