Relations among applied voltage, current, area of electrodes and distance between electrodes were quantified. Two experimental tanks including water re-circulating type and fixed batch type were set up and amount of waste water were both 100 liter. Electrodes were made from stainless steel. 6 plates of 1.4m x 1cm x 1mm and 4 plates of 60cm x 1cm x 1mm were used in the re-circulating and fixed batch tanks, respectively. The removal rate at the first 10 minutes for the waste water at 500μS/cm EC and initial TSS of 200-500 ppm in the re-circulating tank was about 30-40 %. For the waste water at 250-750μS/cm EC and initial TSS of 500 ppm, the highest removal rate at the first 10 minutes was 56.7 %. The TSS removal rates in direct relation to the EC values of the waste water. The removal rate at the first 10 minutes for the waste water at initial TSS of 200-500 ppm and 2 mS/cm EC in the fixed batch tank was 40-50 %. Compare both systems using waste water at 750μS/cm EC and initial TSS of 500 ppm, the removal rate for the fixed batch type at the first 20 minutes was less than the re-circulating type. However, the situation reverse after 1 hour of treatment. The final TSS for the fixed batch type and re-circulating type treatments were 40 and 100 ppm, respectively.中文摘要 i 英文摘要 iii 目錄 iv 圖目錄 vi 表目錄 ix 第一章 前言 1 第二章 文獻探討 3 2.1、水中微氣泡產生 3 2.2、電解水產生之化學反應 4 2.3、電解水的一般應用 6 2.4、廢水的產生、成分與處理 8 2.5、電解設備去除污水中微粒之原理 14 2.6、操作影響因素 15 2.7、設備特性 17 2.8、電解浮除法之應用 20 第三章 實驗設備與方法 25 3.1、前置研究之研究設備與方法 25 3.2、氣泡除污之研究設備與方法 28 第四章 結果與討論 34 4.1、導電度、極板距離和電壓與水中電流之間的關係 34 4.2、循環式浮除設備的設計與初測效果 41 4.3、循環式浮除設備對水中懸浮固體之去除效果 54 4.4、靜置式浮除設備對水中懸浮固體之去除效果 62 第五章 結論 63 參考文獻 71 附錄 74757893 bytesapplication/pdfen-US電解浮除廢水處理waste-water-treatmentTSS-removalelectrolysis電解法用於廢水處理Waste Water Treatment by Electrolysisthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/52827/1/ntu-93-R87631007-1.pdf
