To the wastewater treatment project in Mosslom people daily expenses and chemistry plant in changzhi province,the thesis analysed the pioduce and quality and the ingredient of polluting material of oil-fat wastewater,meanwhile,integrating engineering example, a set of process route line about wastewater treatment was selected,which was dependable in the technology and reasonable in the process.

Preparation of an ASP system using high salinity water from oilfield sewage treated by electrodialysis;

It is difficult for the traditional physical and chemical process to dispose the oilfield sewage up to the discharge standard.

In view of the weaknesses of SY/T 5329-94 in determining oil content of oilfield sewage,a discussion is made on the basis for improvements in standard oil preparation,solvent for extraction,wave lengths for color comparison,and the drawing of typical curve.

The Research of Skidded Oily Water Treatment Equipment;

Study on the Stabilization Mechanism and Oil/Water Separation Chemicals of Polymer Flooding Produced Oily Water;

In order to make the oily water to the quality of return to oil field,the power free oil-water separator, which had function of coagulation,sedimentation and filtration,was used,the coagulant added amount to be optimized based on the test results.
