Abstract


The plasma treatment technology is booming at home and abroad in recent years as a the depth water treatment methods . The subjects developed high-pressure pulsed discharge plasma water treatment device has a simple structure, electrical parameters easily adjustable , wide adaptability , easy to maintain , reliable operation . The device is not only different from the water treatment device with the general electrohydraulic pulse , but can save energy consumption by more than 30% compared with the traditional the ozone generators treatment apparatus currently used , better treatment effect . This paper introduces the principle of high voltage pulse discharge plasma treatment technology , analysis of the relevant factors of the impact of the effect of plasma water treatment , according to is handle the volume of wastewater to determine discharge electrode of a number of methods and equipment rational allocation of the whole device . The experimental device , respectively, and a garbage dump garbage permeate of Chongqing a factory coking wastewater experimental study to identify the main technical parameters of the treatment effect . The device also only after precipitation and filtration of drinking water for sterilization and disinfection , the experimental results show that : after 15 to 30 minutes to process , the kill rate of more than 95% of the E. coli and other microorganisms . The experimental study of the subject , to find out how to determine the main parameters of the plasma treatment equipment .
