1) oil refinery and petrochemical wastewater
By making analysis on the problems existing in original treatment process of a chemical industry wastewater treatment plant,the modification scheme for comprehensive treatment of propylene oxide(PO) saponification wastewater by using oil refinery and petrochemical wastewater as dilution water was presented.
2) refinery wastewater
Discussion on UV_(254) as a predictive index of advance treatment effect for refinery wastewater;
Exploratory test for advanced treatment of refinery wastewater;
Photocatolytic degradation of refinery wastewater with nanometer TiO_2;
3) oil refinery wastewater
Study on treatment of oil refinery wastewater by polysilic aluminium sulphate flocculant;
The physicochemical pretreatment process for oil refinery wastewater was studied.
4) Oil refining wastewater
Experience of oil refining wastewater recovery by the process of combined ultrafiltration and reverse osmosis;
5) refinery sewage
Aiming at serious pollution and no good biochemical quality in refinery sewage,hydrolytic acidification was used to treat it.
Simulating the refinery sewage treatment system, the improved system can not only separate the sludge from the stream ,but also improve the denitrification by secondary sedimentation and adding soften package fiber in secondary sedimentation of the pilot sewage treatment plant in H-O-R process( hydrolysis-acidifying - aerobic- denitrogen ).
模拟茂石化炼油废水生化处理系统 ,在二沉池中加入软性纤维添料 ,使之具有反硝化脱氮的功能后 ,用H -O -R工艺 (即水解酸化 -好氧 -脱氮 )的方式运行 ,不但使泥水分离效果更好 ,而且改进了传统的脱氮工艺 ,弥补由于原工艺中构筑物的原因造成废水无法回流脱氮的缺陷。
The degradation of ammonical nitrogen in the refinery sewage by means of the activated sludge A/O procese is studied through experiments.
6) oil-refining wastewater
Study on oil-refining wastewater treatment by PFSS flocculation-membrane separation;
The integrated hydrolytic acidification-biological aerobic filter was used to treat oil-refining wastewater.
