摘要
磷酸污水封闭循环处理技术是一种处理磷酸生产污水的新工艺，由四个化工操作单元组成：旋流离心分离、絮凝、重力沉降和真空过滤。本文介绍污水封闭循环处理的实验研究主要内容和结果，可作为磷酸污水处理的设计和操作依据。
The closed-circulating treatment processing is a new techniqe, which is used in phosphoric acid wastewater treatment.It is composed of four chemical engineering units:spiral-flow separation, flocculation, graivity sedimentation and filtration.The main results on whole modeling tests of the closed circulation system are presented.which can be used as the theoretical bases of destigning and operating closed-circulating treatment system of phosphoric acid wastewater.
