通过对维生素B₁生产废水混凝试验中是否投加高锰酸钾的试验研究，发现高锰酸钾是一种高效的强化混凝药剂。同时研究了投药顺序、投药量、转速、搅拌时间、pH值、温度等因素对混凝效果的影响，得到了处理维生素B₁废水的最佳混凝条件。

A study about the enhanced coagulation of vitamin B₁ production wastewater has been carried out in respect to the adding of potassium permanganate or not.It is found that is a kind of highly efficient enhanced coagulant.The effects of the factors,such as the feeding order,quantity,stirring time,pH value,temperature,etc.on the coagulation results have also been studied.The optimal coagulation conditions of vitamin B₁ wastewater treatment are obtained.
