Abstract:
Based on jar test, with different matching coagulants of PFA, PSFeZn, PSFe, PAC, Al2(SO4) 3, FeCl3, PAM etc., screen the optimal coagulant and coagulant dose suited for low-temperature and high-color source water treatment, explore reaction mechanisms, make economic analysis. The results show that: the combination of 2mg/LPFA and 0.005 mg/L nonionic PAM obtains the best removal efficiency, removal rate of turbidity, CODMn, UV254, UV350 is 95.60 %, 61.11%, 75.26%, 92.59% respectively, turbidity is 0.4 NTU, color reaches 3.3 degree, above both meet national standards and give full play to double effects of charge neutralization and adsorption bridging, with less dosage, good effect, large alum blossom formation, easy settlement. Medicament expense of unit water treatment is about 0.0032~0.00333 yuan/m3.This research provides the basis for optimizing the follow-up process.
