Experimental Study on Sewage Treatment by Vortex-Grid Flocculation Technology

Abstract:

The aim of this test is to study the effect of treating COD_Cr, NH₃-N, TP and turbidity of sewage with addition of coagulant PAC by using technology of combining vortex-grid flocculation tank with inclined tube sedimentation tank. The results show that the removal rate of devices treating COD_Cr, NH₃-N, TP and turbidity are 68.36%, 22.22%, 82.60% and 80.90% respectively after the stability of the device operation on the condition that the dosage is 25 mg/L and the optimum flocculation time is 17 min.
