Abstract:

This paper takes the urban sewage as treatment target, analyses chemical phosphorous removal effect of PFS, PAC, PAFSI, PAFC and the PAFC which is used by Wu Family Village sewage treatment plant. Taking into consideration of the economic factors in actual operation, the author proposed that the PAFC used by Wu Family Village sewage treatment plant should be served as a chemical auxiliary medicament, under β ≤ 4.33 conditions, β values and effluent TP concentration showed a good correlation. In this paper, the mixing intensity, mixing time, dosage and pH are treated as mainly investigate factors, the four factors and three levels orthogonal test is established. The flocculation conditions of best treatment effect on the effluent TP are as follows: mixing intensity is 200 r/min, stirring time is 90s , dosage is 220 mg / L and pH is 6.CLC number: X703.5
