Abstract:

Through the on site pilot scale experiments, the removal efficiencies of oil and COD of a new type of impeller gas floatation clarifier was investigated. It proved to be feasible for being applied to oil-bearing wastewater treatment. The pilot scale experiments were taken place at the Refinery Department in November, 2005. Now, the results show that it reaches the removal efficiencies of oil and COD similar to that of dissolved air floatation.

Key words: impeller gas floatation clarifier, oil-bearing wastewater treatment, chemical oxygen demand

摘要：

通过现场中试考察了新型叶轮气浮机的除油和除COD效果，以及用于含油污水处理的可行性。中试试验于2005年11月下旬在炼油事业部污水处理场进行。试验结果表明，叶轮气浮机可以达到与溶气浮选池相近的除油和除COD效果。
