Outline
The phosphorus content in phosphating wastewater generated in the coupling production line of a steel tube company was higher and the effect of original coagulation treatment process was not good, so the technical transformation was necessary. The experiment was with three stage coagulating sedimentation and dephosphorization filter unit for adsorption filtration of high concentration phosphorus wastewater. The results showed that the TP of effluent discharging after treatment is nearly completely removed (lower than the national primary standard for comprehensive wastewater discharge 0.5 mg/l) for the phosphating waste liquid with the TP concentration of 5 000~15 000 mg/l and the phosphating wastewater with the TP concentration of 100~200 mg/l as well as the removal rate of TP can be stabilized at about 99%.
