1、萬方數(shù)據(jù)介質(zhì)阻擋放電反應(yīng)器降解甲苯及其結(jié)構(gòu)優(yōu)化研究復(fù)旦大學(xué)碩士論文從降解產(chǎn)物來看，催化管不會(huì)產(chǎn)生硝基化合物，副產(chǎn)物的種類和產(chǎn)生量也相對(duì)較少，初步看來適合工業(yè)推廣。在絕對(duì)濕度為O．4％，初始濃度為208mg／m3的條件下，面．面催化管的甲苯降解率高達(dá)88．6％，能耗僅為187kWh／kg。(5)比較相同初始濃度下排管式反應(yīng)器和套管式反應(yīng)器的甲苯降解率和能耗發(fā)現(xiàn)，兩種類型反應(yīng)器的降解率差異不大。排管式反應(yīng)器在能處理大通風(fēng)量有機(jī)污染物的同時(shí)，又能維持相對(duì)較低的能耗，值得工業(yè)推廣。另外，排管式反應(yīng)器降解甲
2、苯的副產(chǎn)物少，副產(chǎn)物含量較低，初步看來能較好的解決套管式反應(yīng)器結(jié)焦嚴(yán)重的I'口-J題。在外施電壓為10800V，流速為2m／s，初始濃度為270mg／m3的條件下，套管式反應(yīng)器和排管式反應(yīng)器的降解率分別為57．4％和59．0％，對(duì)應(yīng)的能耗分別193kWh／kg和251kWh／kg。關(guān)鍵詞：甲苯，介質(zhì)阻擋放電，降解率，能耗結(jié)構(gòu)優(yōu)化II萬方數(shù)據(jù)介質(zhì)阻擋放電反應(yīng)器降解甲苯及其結(jié)構(gòu)優(yōu)化研究復(fù)旦大學(xué)碩士論文AbstractAsoneofthemostimportantformerbodyofPM2．5，Ph
