| After nearly ten years of development and progress,the process and technology of wastewater treatment in refining and chemical enterprises have made rapid progress.They have been widely used in reality.Chemical treatment,p Hysical treatment and biological treatment have improved obviously in the processing technology and equipment,especially in the combination treatment of wastewater treatment.With the characteristics of pertinence,good treatment effect and reasonable layout,it has gradually become a mainstream technology of wastewater treatment in refining and chemical enterprises.A chemical enterprise has adopted the technology of "iron carbon filler micro electrolysis + ozone oxidation" technology to treat the wastewater of three hydroxymethyl propane unit.After a period of operation,it can not meet the requirements of pollutant discharge.The characteristics and processing technology of wastewater in a chemical enterprise are analyzed and analyzed.After the study,the "anaerobic pond(AF)+ high efficiency aerobic fixed membrane bio-reactor(HFBM)+ aerobic tank + coagulation air flotation" treatment process was decided.In this paper,the relevant equipment of the project is described in detail,and the project is analyzed and evaluated from the aspects of project overview,process,construction and transportation,automatic control and electric meter,building and structure,environment and so on.In the end,it is proved that the design plan of a technological transformation project for wastewater treatment in a chemical enterprise is suitable for the actual situation of the enterprise and is feasible. |
