Study On Yulin Refinery Wastewater Treatment And Modifying Process

To solve the problem of water resources shortage and reduce the environmental pollution caused by the discharged waste in the petrochemical company,a research of advanced wastewater treatment process was carried out in the trial-scale test.The aim of the research was to develop an advanced treatment process based on the core technique of ultrafiltration and reverse osmosis treatment for the petrochemical waste.This technique took the petrochemical waste attained the national discharge standards as the test wastewater and made it to meet the quality demand of supplementary water for the industrial circular cooling water.Aiming at the problems existing in present oilfield wastewater treatment,the wastewater quality of Yulin refinery was monitored and researehed in this paper.This paper did a targeted research,combining the operation situation of wastewater treatment devices in Yulin refinery,it found out the shortage and defect of materialization treatment technical in traditional wastewater treatment processes,and did evaluation research on the effect of ultrafiltration and reverse osmosis technology in oilfield of project case.Laboratory experiment selected the anti-scale and corrosion inhibition pharmaceutical for Yulin refinery wastewater treatment.In the above study over Yulin refinery,combining the transformation of wastewater treatment device,this paper raised the "biochemical treatment + ultrafiltration and reverse osmosis" programs,which is for wastewater station's transformation in the future.
