Advanced Wastewater Treatment

Our country is short of water, the demand for water is increasing in production and life with the rapid development of economic society. The shortage of water has become a bottleneck of development of our national economic society, protecting limited water and harnessing the resource of water has been an important strategic task.The dissertation summaries some current treating processes of sewage and analysis the process and offer feasible treating technological process of water in Daqing Oilfield Methanol Plant. The method of combination of Biochemistry and electronic oxidation is adopted to treat the sewage. It shows that COD, chlorine ion, suspension can be decreased and PH can be adjusted, in the meantime, calcium ion, magnesium ion, alkaline ion and phosphorus ion can be decreased by taking the measure, the standard of treating water is good according to national ones of recycling water. We ought to see that the amount of supply of fresh water is decreased after the sewage is harnessed and save the resource of water and decrease the cost of production and improve the economic benefit of enterprise.
