Description

technical field

[0001] The invention relates to a method and a device for adding a coagulant to sewage, belonging to the technical field of sewage treatment. Background technique

[0002] In the prior art, in sewage treatment and water purification, coagulation is one of the very important units. It uses coagulants to change the state of particles in water, destabilize suspended components and colloidal components in water, and in a certain Under certain conditions, such flocs are formed that can be separated by sedimentation or air flotation, and then this part of the flocs is separated by sedimentation or air flotation. In the coagulation treatment, the coagulant used is the key to the treatment. Now many researchers are actively researching and developing composite coagulants or flocculants, but iron salts or aluminum salts are mainly used. The existing Various coagulants still have some problems. For example, in the process of sewage treatment, the reaction is slow, som...
