摘要
利用电液压脉冲技术控制水体中的藻类,改变电液压脉冲放电系统和电极的结构,使电液压脉冲装置既具有高压、高温、强紫外线、空化流、冲击波和自由基等作用,而且又是一台在水体内直接产生臭氧的发生装置。对这种直接在水体内产生臭氧的发生装置的结构和影响臭氧产率的主要因素进行分析,并对本装置的主要电气参数,水下臭氧发生装置的一组电极的有效作用范围进行了论述。研究表明,采用本技术后不仅能直接在水体内产生臭氧,使臭氧和水体的反应在被处理的水体中完成,而且在高压、高温、强紫外线、空化流、冲击波和自由基等的辅助作用下,使水体更好地发生离解反应和氧化,通过调节放电脉冲频率和电流的脉冲幅值等参数来调节所需要的臭氧量,从而更有助于湖泊水体富营养化的治理。
In order to study on controlling water body algae,an underwater ozone generator has been developed by electro-hydraulic power impulse technology according to altering the discharge electrode.The structure of underwater ozone generator and the factors influencing ozone productivity have been discussed.Electrical performance of electro-hydraulic power impulse technology have been established and the electrode effective working areas of the ozone generator has been also calculated.The results show that dissociation reaction of lake water and radical oxidation happen by increasing the ozone of electro-hydraulic power impulse technology.Moreover,the production and reaction of ozone are completed in lake water body.By adjusting the electric field intensity,discharged pulse frequency and pulse amplitude of the current,ozone can be obtained as requirement,and it benifit to control eutrophication of water body.
