Abstract
In response to the difficulties in separating phosphorus containing substances and mud,and recovering phosphorus in the wastewater treatment system,as well as environmental risks,safety hazards,harsh working environment,and high production costs,a yellow phosphorus plant in Guizhou province has proposed a process treatment solution to move the sewage tank of the yellow phosphorus plant from underground to the ground,comprehensively optimizing and renovating the process flow,equipment,and electrical automation.After the renovation,the water quality indicators of the wastewater treatment meet the national standard requirements,reducing production costs by 112.35 RMB Yuan per ton,increasing the phosphorus recovery rate and generating a direct economic value of about 5 million RMB Yuan,improving the working environment.
