the flocculating purification of yellow phosphorus wastewater with starchacrylamide graft copolymer (sgm) is described. its purification effect is better than that of polyacrylamide (pam).
介绍了淀粉丙烯酰胺接枝共聚物(sgm)对中和后的黄磷废水的絮凝凈化作用,其处理效果超过聚丙烯酰胺(pam)。
physical-chemical process which can be divided into settlement-oxidation method and closed-circuit method is used most widely in the field of treating yellow phosphorus wastewater in our country now.
目前国内黄磷废水处理通常采用物化法,其又可分为沉淀氧化法和闭路循环法。
in this paper, the method of closed-cycle was used to treat with yellow phosphorus wastewater containing iodine. the purity of iodine sample reached 95.5%.
对含碘磷矿石生产磷产品时产生的废弃物(废水)采用闭路循环法处理,在消除有害物质对环境污染的同时回收碘,所得碘样品含碘95.5%。
