Abstract:This paper introduces the original liquid feeding method of the centrifuge high tank in the gypsum process of wastewater treatment, and analyzes its existing problems and disadvantages according to the actual production situation. In order to improve the liquid feeding efficiency of the centrifuge, two centrifugal pumps were added to replace the original high tank liquid feeding method,and the control mode was adjusted accordingly. After the new model was put into operation, good results were achieved, and the original system's shortcomings such as low efficiency, complicated pipelines, easy blockage of pipelines, and high energy consumption were solved.
