Study on Optimization Process of Containing Phenol Wastewater Treatment with Pulse Corona

LIU Cheng-lun~(1,2),YANG Yu-ling~1 (1 College of Chemistry and Chemical Engineering,Chongqing University,Chongqing 400044,China;2 Key Lab.for the Exploitation of Southwest Resources and Environmental Disaster Control Engineering of Ministry of Education,Chongqing University,Chongqing 400044,China)  
The optimization process is obtained after analyzing the quality items of wastewater.It is concluded that electrode arrangement way is the way of stainless steel awl and plane iron.Continuous discharging is of benefit to destruction in former 0~60 min when the concentration of phenol solution is high,and discharging at regular intervals is more effective to the decrease of Chemical Oxygen Demand(COD) in 60~90 min when the concentration of the solution is low.Moreover,the changing trend of COD in the solution is steep in former procedure for the awl electrode anode.The decrease degree of COD is obvious for the awl electrode cathode in later procedure.In addition,it is helpful to prevent the increase of conductivity when NaOH is added into the solution.The curve of Biochemical Oxygen Demand ∶Chemical Oxygen Demand(BOD_5/COD) vs.time is a parabola.
