Abstract: Due to the different types of petrochemical products,the performance of the water quality is very different,because of the increasingly stringent standards; the difficulty of plant to study sewage treatment is increasing. This paper selects the object of salt sewage treatment device containing a petrochemical,data statistics and analysis of existing sewage treatment water quality,pretreatment stage problems,biochemical treatment problems,and according to different problems and put forward feasible measures and suggestions. By improve the accident tank,increase water quality improvement analysis of frequency fluctuation test,pre flotation device to improve the effect of pretreatment with the addition of special strains,improve the efficiency of biological treatment and other measures,the basic realization of optimal operation,and improve the removal efficiency of pollutants,sewage discharge standard target.
