| Abstract: | Washing coal gas wastewater was treated by four coagulants, Al2 (SO4)3 PAC PFS and FeSO4respectively, and their COD removal efficlencies were 63. 9%, 67. 4%, 61.3% and 57.4%, the emulsified oilremoval efficiencies were 71.6%, 75.6%, 74.8% and 70.5%, the turbidity removal effciencies were 93. 4%,94. 1%, 95. 6% and 90. 1%, and the expenses for medicament of removing per kilogram CODcr. in wastewaterwere 680. 5, 650. 4, 464. 8 and 318. 2 yuans, respectively, The results showed that PFS had both good treatmenteffect and low cost, FeSO4 had the lowest removal efficiency among them but the lowest cost. |
