the flocculating purification of yellow phosphorus wastewater with starchacrylamide graft copolymer (sgm) is described. its purification effect is better than that of polyacrylamide (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%.
