Jinxi Petrochemical Company Sewage Treatment Study

Water is one of essential base substances in daily life and production. Water used must be discharged with all kinds of polluted substances,which brings severe danger to the environment influences the normal life and production activities of the society,even does harm to the people's health. With the development of production and progress of the socity,the pollution of water turns more and more prominent.People come to realize it is important to harness the sewage,therefore many kinds of techniques of sewage-harnessing have been shown.Jinxi Petrochemical Complex Company of China Petroleum is located to the west of Liaoning province,and near the Bay Bohai where water is scarce,and pollution is serious.The environmental protection departments of the nation,province and municipality pay more attention to pollutin than before, the strict policy is established to ensure the qualified sewage discharging.The enterprise's former sewage plant can not meet the environmental protection in the field of procession and capacity. The thesis gives an deep research on harnessing sewage as follows base on the fact of factories.(1) According to the investigation and study to the situation of the sewage,the shortage is found,and the sollution is brought forward ,predisposing facitlities improved and strengthened.A/O biochemical system added.(2) The way of the landfill of solid waste is confirmed for polluted mud produced during the process of disposing sewage,and the main part of landfill of solid waste is researched critically ,and the film of HDPE ,which has the leading opinion ,is brought forward in the way of constuction and examination.(3) The recycling techniques of sewage that STS and Sta Maria Water AB Companies aim at Jinxi Petrochemical Complex Company is researched to prove its feasibility.(4) The shortage is found in water supply and drainage,and the technical project of saving water and decreasing pollution is brought forward,furthermore the medicament of disposing recycling water is researched.Many feasible techniques and projects of disposing sewage are found,which is the outcome that disposal of sewage,the landfill of solid waste, recycling sewage,saving water and decreasing pollution and so on,a series of disposing sewage are researched and analysed ,merged into pratical production,therefore the better effect is received in practical application.
