【 摘 要 】

Flocculant PFZSSB (MD-F02) was used to treat coking wastewater. In order to solve the problems such as excessive dosage and low flocculation effect in practical application, the dosing sequence and dosing time in the preparation of MD-F02 were studied to improve the flocculation effect. Based on a lot experiments, the optimal parameters were determined i.e. the dosing sequence of Zn> Fe> B, the dosing time of Zn, Fe, B of 5, 20, 10 min, respectively. The removal rate of SS was up to 90% and the removal rate of chemical oxygen demand (COD) was close to 50% under the dosage of modified MD-F02 of 125 mg/L.
