摘要
对重质原油废水采用气浮+水解酸化+A/O+Fenton+BAF的组合工艺进行了中试试验,结果表明所采用的组合式处理工艺对该类废水中的COD、氨氮、石油类等污染物均有较好的处理效果,处理出水可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)中的一级A类排放标准。
Pilot experiments of treating heavy crude oil wastewater by a combined process of flotation ＋hydrolytic acidification ＋A/O＋Fenton ＋BAF were carried out. The experiment results indicate that the combined process can effectively remove COD、ammonia nitrogen and petroleum pollutants in the heavy crude oil wastewater. And the effluent can reach class 1A of discharge standard of pollutants for municipal wastewater treatment plant （GB 18918—2002）.
