Coagulation-flocculation process is one of the most commonly used treatment process in water and wastewater treatment. Particles (PA) and phosphates (P) removal are the main objectives in wastewater coagulation. There is a general agreement on the dominant mechanism of PA and P removal during coagulation. While it is agreed that the PA and P removal reactions are competitive and takes place simultaneously, there is no clear understanding on the ratio of distribution of coagulants among the PA and P removal. The ratio can be significantly influenced by the content of PA and P, in addition to other water and coagulant quality factors. This paper attempts to provide a qualitative ratio of coagulant distribution based on PA:P proportion in raw water and OH:Al ratio in coagulants.
混凝絮凝工艺是水和废水处理中最常用的处理工艺之一。去除颗粒（PA）和磷酸盐（P）是废水混凝处理的主要目标。关于混凝过程中PA和P去除的主导机制已达成普遍共识。虽然人们一致认为PA和P的去除反应具有竞争性且同时发生，但对于混凝剂在PA和P去除之间的分配比例尚无清晰认识。除其他水质和混凝剂质量因素外，该比例会受到PA和P含量的显著影响。本文试图根据原水中PA:P的比例以及混凝剂中OH:Al的比例给出混凝剂分布的定性比例。
