Design and Application of Polystyrene Wastewater Treatment Engineering
In response to the difficulties of phosphorus content,high wastewater concentration,and poor biodegradability in the polystyrene production wastewater of a polystyrene chemical plant in Anhui Province,the"coagulation precipitation method"is first used to pretreat the waste water,effectively removing phosphorus.Then,it is combined with other wastewater and treated through the"hydrolysis acidification+active aerobic pollution+precipitation"process.Finally,the effluent Chemical Oxygen Demand(COD),total phosphorus and other pollutants remain stable below the local takeover standards.The investment and operating costs of the project design meet the expectations of the enterprise.
