Optimize The Membranes Technology Of Daqing Petrochemical Company Wastewater Reusing Device

With the rapidly increasing population in the world and the development of industry, the world is facing a serious water crisis, 1 / 3 of the population are in a tension ofwater . Petrochemical enterprises face this problem more serious, onthe one hand there is a sharp contradiction between supply and demand of water resources, on the other hand the waste of water resources is serious, fuel consumption of water processing and consumption and emissions of water are huge . Wastewater reusing technology,which not only significantly reduce water consumption and sewage efflux, but also reduce the cost, is used by Daqing Petrochemical Company in November 2004.Wastewater Reusing device mainly includ reverse osmosis membranes and membrane technology. Through more than a year of operation,it has been found that the effect of "double membrane" relateswith the fluctuations of upstream water, the frequency of film's anti-washing, the time of backwashing and the consumption of Pharmacy. At present, the output of the device is 7000 t / d, if the whole system would be further optimized, the potential of this device is very huge.In this paper, it use Daqing Petrochemical Company wastewater reusing devices astarget devices demostrating the principle of double membrane sewage treatment process in the refining of the film production water and sewage blocking the low rate of the problem, it ? the field of energy saving , the water balance and the comprehensive utilization of research projects.This paper the sewage treatment device used by Daqing Petrochemical Company membrane used to purify the sewage water recycling water market, water quality and stability, reverse osmosis membranes for treatment to purify the sewage water desalination, water stable, two-run films , The cleaning process of cleaning effectbad, the water rate to analyze the reasons for declining to identify the relevantfactors, the operating parameters of the scene changes, statistical data accountingoperations, the best set of operating parameters, the best film Cleaning and regeneration process, improving the efficiency of membrane and water-rate approach. The content of glycerin monostearate was determined with oxidation process of periodic acid, the structure of glycerin monostearate was characterized with determining melting point, analyzing infrared spectrum and mass spectrum.
