摘要
阐述了在一定酸度下 ,通过加热减压等条件蒸发浓缩聚醚废水 ,析出白色晶体磷酸二氢钾的工艺过程。对产品进行分析鉴定 ,并通过 X光衍射证明产品的纯度及回收的磷酸二氢钾在污水处理中的应用情况。
The technology processing of potassuim dihydrogen phosphate, a white crystal from the waster water in polyether device, with heated and reduced pressure distillation, concentration of waster water for polyether in the pH value, was described. The product was analysised and pure of the product was botained by Xraying. The application of the product in sewage disposal was described also.
