RESUMO
The application of resonance charging circuit to electro-hydraulic impulse apparatus for treating wastewater is introduced in this paper.The circuit permits the graduating increase of current without influence from time.The unique change of voltage on capacitor is favorable for the recovery of electric strength of electro-hydraulic impulse apparatus.The theory and design method of resonance charging circuit are provided.
RESUMO
It is an urgent task to purify drinking water and treat industrial wastewater at present.In this paper,the operating principle of the electro -hydraulic impulse apparatus and its sterilization effect is introduced,which is effective in purifying drinking water and treating wastewater.Based on the laboratorial data and theory analysis,method of parameter selection for the apparatus is also presented.
RESUMO
The electrohydraulic impulse water treatment equipment is developed to purify the drinking water and treat with the wastewater from industry production and living.Taken as the negative electrode,the air jet nozzle can input the air or oxygen into the working chamber,and thus the equipment is turned into a generator of low-temperature plasma ozone and its sterilization effect is vastly enhanced.According to experimentations and references,the factors that influence the erosion of electrode are discussed in detail in this paper.The metal ions in water have to be limited during the electrohydraulic impulse sterilization,or the sterilization effect will be weaken.
