【摘要】 通过试验对炼油废水絮凝剂进行了筛选。结果表明 ,有机高分子絮凝剂 (PAM、HL - 70 4 )与无机絮凝剂 (PAC)复配显著提高了油类和COD的去除率 ,复配絮凝剂具有投加量少、适用性强等优点。更多还原

【Abstract】 Flocculant for refinery wastewater treatment was selected by experiments. Results showed that the selected organic high molecule flocculants (PAM or HL-704) combined with inorganic flocculant PAC remarkably increase removal efficiency of oil and COD. The complex flocculants have advantages of stronger adaptability and lower dosage than any flocculant used individually.更多还原
