Description

Polymerized ferric sulfate automatic feeding system and method thereof

technical field

The present invention relates to an automatic feeding system, in particular to an automatic feeding system for polyferric sulfate.

Background technique

At present, in the treatment of urban water and industrial wastewater, the economical and simple flocculation-sedimentation method is widely used at home and abroad to purify water quality. The quality of the flocculation effect will affect the treatment cost of the subsequent process of the water treatment process, and even affect the quality of the final effluent.

Polyferric sulfate solution is widely used in the treatment of urban water and industrial wastewater because of its excellent coagulation performance, fast settling speed, safety and non-toxicity, and excellent water purification effect. However, the feeding method of polyferric sulfate at the present stage is generally to dilute the polyferric sulfate solution and directly put it into the clean water pool by hand. The dosage and speed of the solution are poorly controllable, which affects the treatment effect. Therefore, it is necessary to develop or improve the feeding method and equipment of the existing polymeric ferric sulfate, and develop an automatic polymeric ferric sulfate feeding system to realize the controllable adding amount and adding speed of polymeric ferric sulfate, so as to achieve excellent water purification effect.
