物化法处理氟苯生产废水技术

TREATMENT OF FLUOBENZENE WASTEWATER BY PHYSICOCHEMICAL METHODS

研究酸化+萃取+无机除氟+粒子群电催化氧化等物化技术处理氟苯生产废水的工艺条件。在适宜的工艺条件下,废水中CODCr、苯酚、F、石油类去除率可分别达到99.2%、99.99%、99.9%、99.5%以上,出水CODCr、苯酚、F-、石油类、TOC均低于《污水综合排放标准》(GB8978-1996)中一级排放标准限值;同时可回收废水中苯酚,实现废水资源化。

It was studied that the process conditions of treating fluobenzene wastewater with acidification, extraction, inorganic fluoride removal and electrocatalysis. At the suitable conditions, the removal rates of COD_ Cr , phenol, F-and petroleum are over 99.2%, 99.99%, 99.9%, 99.5%, the effluent indexes such as COD_ Cr , phenol, F-, petroleum and TOC were lower than the limiting value of primary standard of the 'Integrated Wastewater Discharge Standard'(GB8978-1996). At the same time, phenol in the wastewater can be recovered and reused.
