| Abstract: | The experimental results have been reported in this paper about which the flotation of coking plant wastewater was carried out with a new type of laboratory CAF flotation cell after flotation reagents are added. In the conditions of 3 min. of flotation and 18 min. of flotation separation, with the PASS and PAM as combined flocculants, COD cr, oil and color degree of the wastewater are decreased from 6800mg/L to 1830.4mg/L, 6893mg/L to 13.78mg/L and 400 to 100 respectively, that is the removal efficiency of the COD cr, oil and color degree are 56.5% and 99.8% respectively. Most of the oil and hard-to-degrade large-molecule organic materials in coking plant wastewater were removed after flocculation-flotation, which supplied a good condition for its further purification. |
