摘　　要：基于提高含油废水处理效率,对新型(管式反应、高效溶气)溶气气浮装置进行了试验研究。结果表明:在流量0.50 m3/h、PAC投加量60 mg/L、回流比20%、溶气压力0.60 MPa、絮凝速率0.80 m/s条件下,该装置对含油废水中油和SS的去除率分别达到了96%和85%,去除效果良好,运行稳定,在含油废水及更为广泛的废水处理领域有着广阔的应用前景。A new type of dissolved air flotation apparatus with pipe type reaction and high - efficient dissolved air was studied for improving the treatment efficiency of oil wastewater. The results showed that the oil and SS removal rates of oil wastewater came up to 96% and 85% respectively under the condition of flow 0.50 m^3/h, PAC 60 mg/L, reflux ratio 20%, dissolved - air pressure 0.60 MPa and coagulation rate 0.80 m/s, which indicated that the new apparatus had high efficiency and stable operation in treating oil wastewater and would have broad application prospect in oil wastewater and other wastewater treatment field.
