A new method for the determination of chloride ion in oil refining industry sewage by automatic electrictitration method was recommended.

Application of automatic control system to BAF process for treating refinery wastewater;

The Noted Problems in Refinery Wastewater Treatment of Oxidation Ditch;

BAF & coagulation and sedimentation & activated carbon absorption applied on refinery wastewater treatment;

Treatment of refinery waste water by biological aerating filtration- multiple agent filtration-electric adsorption processs;

A new technique for measuring COD of refinery waste water with microwave sealed digestion apparatus was developed using copper sulfate as catalyst.

The extraction of organic constituents in four kinds of refinery waste water with CH2Cl2 was conducted in alkalic and acidic conditions, respectively.

In order to investigate the feasibility of biofiltration elimination of malodor from oil refining wastewater treatment plant,two biofilters in series packed with a mixture of compost,bark and lava,which each consisted of three segments were used in this study.

In the study, Fe/Cu micro-electrolysis was used to treat oil refining wastewater, withthe help of chemical flocculation in pretreated treatment and similar Fenton oxidization inadvanced treatment.

The results of its pilot operation showed that MBR for treating oil-refining wastewater had good quality of the effluent;the average values of COD,ammonia-nitrogen,oil and phenol in effluent could lower to 39mg/L,2mg/L,3mg/L,and below 0.

Therefore, it is interested in seeking for the treatment process of oil-refining Wastewater with effective feasibility, credible economy and convenient management.
