摘 要
介绍湿法磷酸生产过程中水平衡的控制｡其突出的特点是采用分级综合利用措施,进行清浊分流,对高磷废水中P2O5进行回收,减少磷的损失；低磷废水进行排污处理,降低污水处理成本,为企业节约和挽回经济损失约1 572万元 / a｡

Abstract
Control of water balance is described from WPA production. The classifying utilization measures is used for stratifying flows of clear liquid and cloud liquid, the P2O5 is recovered from the waste water of containing high-phosphorus for reducing phosphorus loss；the waste water of containing low-phosphorus is discharged for reducing the water treatment cost, saving and retrieving economic losses is almost 15.72 million RMB Yuan / a.
