A parallel operation of three atmospheric non-thermal argon plasma jets was applied for leachate treatment with water sample in strong acidic condition $(mathbf{pH} < 2)$. Three cases with different gap distances for 1.5, 3 and 4.5 cm were employed with a $4.5 mathbf{kV}_{text{rms}}$ 50 Hz AC neon sign transformer power source for 60 minutes. In this time, the influence of electrode gap distance $(text{G}_{text{d}})$ of argon plasma jet on the degradation of refractory organic compounds in biotreated landfill leachate was observed. Some key parameters of water quality including pH, DO, temperature, COD and the macromolecules, such as humic and fulvic substances, were measured before and after treatment. The result showed that the maximum removal of COD (33.9%), fulvic (53.3 %), humic (32.2%), and visible humic substances (57.2%) was found with the operating condition in 4.5 cm $text{G}_{text{d}}$ case. It could be confirmed that atmospheric non-thermal Ar plasma had the potential to effectively reduce the refractory organic compounds in wastewater which could be exploited for post-treatment of biotreated landfill leachate.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"56 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77876247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the background interference, the multi-bounce effect is unavoidable and will contaminate the measuring result greatly. In this paper, a novel method to eliminate the multi-bounce effect via 3D imaging technique is proposed. Compared with the traditional methods, high-resolution 3D microwave image can separate the desired image from the multi-bounce false images in the image domain by using the difference of the transmission paths. Simulation results show that this method can clearly eliminate the multi-bounce effect of the outdoor RCS measurement.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"14 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74281019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduced single-stage inverter has buck-boost feature, which provides the desired output AC voltage.
