Enhanced Effect Of Micropores On Dielectric Barrier Discharge And Its Application In P-Chlorophenol Wastewater Treatment

p-chlorophenol,a powerfully toxic,environmentally hazardous,hardly degradable organic compound,is treated with advanced oxidation,one of which is isoionic discharge.The issues of the technique are electrode protection,generation of active species.The construction of micro-porous structure in medium is employed to solve the problem due to medium discharge promote.In addition,the apparatus for micro-porous discharge promote,the aqueous treatment apparatus for micro-porous discharge promote,the micro-porous bubble apparatus coupled with isoionic discharge are self-made in the research.The discharge promotion mechanism and the ozone generation are studied in the apparatus of micro-porous discharge promote.It is discovered that the discharge process functions as micro-hollow cathode to promote discharge promote in medium,in addition,ozone generation is associated with air rate,voltage and micro-pore quantities.Ozone generation in the apparatus is more than that in traditional double-medium promote to prove the significance of micro-porous discharge promote.Aqueous p-chlorophenol is treated in the aqueous treatment apparatus of micro-porous discharge promote to check the energy efficiency of the various micro-pores.The discharge details are probed.Based on structural feature of the apparatus,micro-bubble is attempted in isoionic body.The result shows the degradation of p-chlorophenol is affected by its initial concentration,pH,salty content,voltage,air flow.In addition,micro-pore aids chlorophenol degradation and low energy consumption,whereas micro-bubble in isoionic body favors wastewater treatment.In the isoionic discharge body coupled with micro-bubble apparatus,discharge promote in multi-porous medium & micro-porous medium achieved in combination between isoionic body and micro-bubble technique.The treatment efficiency reaches over 95%.In summarization,micro-pore functions as discharge promote in medium to improve ozone generation & low energy consumption in the medium.In addition,micro-porous discharge promote in medium achieves in micro-bubble in isoionic body.The mass transfer between isoionic phase and aqueous phase is improved,and so does wastewater treatment.
