簡介：Y654608HSB高效微生物技術(shù)處理城市污水一體化裝置研究環(huán)境工程專業(yè)研究生楊光指導(dǎo)教師姚建、龔健我國地表水水體污染主要來自于工業(yè)和城鎮(zhèn)，其中50以上來自城市污水。特別是像攀枝花這樣的山地城市，城市污水點多面廣，大型污水廠建設(shè)用地緊張，污水收集難度極大。因此，需要一種結(jié)構(gòu)簡單緊湊，占地面積少的污水處理裝置。通過調(diào)研、考察和前期小試，經(jīng)認真分析研究后，決定采用HSB高效微生物技術(shù)，結(jié)合常見的一體化污水處理裝置，改進傳統(tǒng)的長流程工藝為短流程工藝，研制集好氧、兼氧、厭氧和污泥自回流為一體的“HSB高效微生物技術(shù)處理城市污水一體化裝置”。中試結(jié)果表明“HSB高效微生物技術(shù)處理城市污水一體化裝置”占地面積少，投資省能耗低，運行成本低凈化率高，污泥產(chǎn)生量小，僅為傳統(tǒng)活性污泥法的110120工藝簡單，機電設(shè)備少，操作維修方便，管理成本低出水水質(zhì)好，各項指標均優(yōu)于國家一級排放標準GB89781996。和其它活性污泥法相比較，更加適合在像攀枝花這種居住區(qū)分散、建設(shè)用地緊張的西部地區(qū)的山地城鎮(zhèn)推廣。同時，“HSB高效微生物技術(shù)處理城市污水一體化裝置”中試的成功經(jīng)驗，也為焦化、造紙、印染、制藥、制糖等領(lǐng)域的高難度工業(yè)生化污水的處理，起到了良好的借鑒作用。關(guān)鍵詞HSB微生物城市污水一體化裝置USINGHSBHIGHEFICIENTMICROBIALTECHNOLOGYWHICHCOULDUNIFYTHEAEROBICANOXICANAEROBICANDSLUDGEAUTORETURNMEDISCALETESTINDICATEDTHISINTEGRATIVEEQUIPMENTUSINGHSBHIGHEFICIENTMICROBIALTOOKUPLESSPLACEREQUIREDLESSINVESTMENTEXHAUSTEDLESSENERGYCOSTLESSDURINGOPERATIONTHEPURIFYINGRATEOFITWASHIGHANDTHESLUDGEYIELDWASLITTLEONLY110120OFTHETRADITIONALACTIVESLUDGETECHINCSTHEELECTRIFIEDMACHINESUSEDWASFEWANDITCANBEOPERATEDANDREPAIREDEASILYTHEMANAGEMENTCOSTWASALSOLOWWHATSMORETHEQUALITYOFTHETREATEDOUTWATERWASGOODEVERYINDEXWASBETTERTHANTHEFIRSTLEVELOFTHENATIONALEMISSIONCONTROLCRITERIONGB89781996COMPAREDWITHTHEOTHERACTIVESLUDGETECHNICSITWASMORESUITABLEFORTHISNEWTECHNOLOGYTOGENERALIZEINTHEMOUNTAINOUSTOWNSSUCHASPANZHIHUAINTHEWESTREGIONSMOREOVERTHESUCCESSFULEXPERIENCEOFTHEMEDISCALETESTOFTHISNEWTECHNOLOGYCOULDBEUSEDFORREFERENCEINTHETREATMENTOFTHEHIGHSTRENGTHINDUSTRIALWASTEWATERWHICHCAMEFROMFIELDSSUCHASCOKINGPAPERMAKINGDYINGPHARMACYSUGARREFININGANDSOONKEYWORDSHSBMICROBIALMUNICIPALWASTEWATERINTEGRATIVEEQUIPMENTS

簡介：隨著住宅改革和人民生活水平的提高，大量建筑材料和裝飾裝修材料被人們所使用。這些建材和裝飾裝修材料釋放的甲醛，三苯等揮發(fā)性有機化合物VOCS，VOLATILEGANICCOMPOUNDS已成為室內(nèi)污染的主要來源。由室內(nèi)裝修釋放的有害氣體造成室內(nèi)環(huán)境污染越來越引起人們的關(guān)注。本課題針對室內(nèi)裝修污染提出烘焙排風(fēng)及生物處理一體化技術(shù)。整個技術(shù)可以分為烘焙排風(fēng)稀釋和后期生物處理兩個階段。首先采用烘焙與排風(fēng)的復(fù)合作用加速污染物的揮發(fā)速度，并對室內(nèi)污染進行稀釋，然后經(jīng)過生物處理裝置來處理排向大氣的有害氣體。通過以上方法可以簡便高效地去除室內(nèi)裝修有害物質(zhì)，同時避免了對室外環(huán)境造成污染，是解決室內(nèi)裝修污染和改善室內(nèi)外環(huán)境與空氣品質(zhì)行之有效的新方法。應(yīng)用烘焙排風(fēng)及生物處理一體化技術(shù)對室內(nèi)甲醛和三苯的去除效果進行研究，結(jié)果表明甲醛的濃度降低率在268～52％，苯、甲苯和二甲苯的濃度降低率在73～100％。在其他因素相同的條件下，含間歇性通風(fēng)比無間歇性通風(fēng)技術(shù)對室內(nèi)環(huán)境中有害氣體的去除效果好。對于烘焙排風(fēng)階段，本文在詳細分析揮發(fā)性有機化合物擴散機理的基礎(chǔ)上，利用數(shù)值計算模型，結(jié)合已得到的實測數(shù)據(jù)確定出烘焙排風(fēng)的最佳方案。對不同烘焙時間、烘焙溫度、通風(fēng)時間、換氣次數(shù)下?lián)]發(fā)性有機化合物的排放量、室內(nèi)濃度變化進行了探討。提高烘焙溫度、換氣次數(shù)，延長烘焙時間、通風(fēng)時間均可以增大揮發(fā)性有機化合物的排除量，但各項因素所起到的作用效果有所差異。對于生物處理階段，本文采用吸附生物膜理論進行了動力學(xué)分析，與實驗數(shù)據(jù)的對比顯示，兩者有良好的相關(guān)性。相關(guān)系數(shù)苯R09995、甲苯R09996、二甲苯R09996。烘焙排風(fēng)后的有害氣體經(jīng)過生物處理再排入大氣時，甲醛、苯、甲苯、二甲苯的凈化效率分別為100％、489％～73％、662％～947％、663％～90％。本文的研究結(jié)果對簡便有效地解決室內(nèi)裝修空氣污染問題提供了新方法，并為確定烘焙排風(fēng)稀釋及生物處理一體化技術(shù)的最佳方案提供了理論依據(jù)和技術(shù)參數(shù)。

簡介：隨著我國經(jīng)濟的快速發(fā)展和生活水平的日益提高，提高對分散式污水的處理率和處理水質(zhì)已勢在必行。然而，傳統(tǒng)的脫氮除磷工藝要求較大的污泥回流量和硝化液回流量，需要較高的污水處理成本及管理操作要求，并不適合我國分散式污水的處理要求。為此，本文在充分分析已有工藝特點的基礎(chǔ)上，設(shè)計了一種新型、高效的一體化反應(yīng)器，并對其性能進行了實驗研究。整個實驗研究由三個部分組成第一部分以模擬生活污水為處理對象，主要考察HRT、溫度等對反應(yīng)器的處理性能的影響；第二部分是為了進一步提高反應(yīng)器的脫氮性能，探討在分段進水時的處理性能；而第三部分是在綜合分析前兩部分研究結(jié)果的基礎(chǔ)上，確定處理工藝和工況條件，并以實際的生活污水為處理對象進行驗證實驗。獲得的主要研究結(jié)果如下1設(shè)計和制作了一種以分散式生活污水為處理目標的高效的一體化反應(yīng)器。其主要特點為多級AO串聯(lián)，無混合液及污泥回流，以過濾床代替二沉池，反應(yīng)器均采用多孔彈性材料為載體，在高效去除有機物和氮磷的前提下，既簡化了工藝流程，降低了能耗又方便了運轉(zhuǎn)管理。2第一部分的研究結(jié)果表明，在實驗水溫范圍內(nèi)，當HRT為12H時，反應(yīng)器對污染物的去除率與HRT為9H時相比沒有明顯的提高，但HRT為12H或9H時的污染物去除率均明顯高于HRT為6H，因此HRT取9H較為合適。水溫的變化對有機物的去除影響不大，但對NH3N和、TN的去除影響比較顯著。水溫由15℃上升至25℃時，NH3N和TN的去除率分別增加了373％和221％。在HRT為9H、水溫為25℃，以及模擬生活污水中COD、NH3N、TN、TP、SS的濃度分別在350～450、264～369、270～385、17～26及267～345MGL范圍內(nèi)時，相應(yīng)的污染物去除率分別達到了957％、970％、514％、635％及939％，處理水水質(zhì)指標均能滿足城鎮(zhèn)污水處理廠污染物排放標準GB189182002中的一級排放標準。3第二部分的研究結(jié)果表明，盡管采用了分段進水方式，反應(yīng)器對TN的去除率并沒有得到提高，沒有能夠?qū)崿F(xiàn)提高脫氮率的預(yù)期目標。不過，由于分段進水的方式可以分散進水負荷、提高抗沖擊負荷的性能，因此在實際應(yīng)用中仍有一定的價值。4由于一段進水與多段進水的處理性能幾乎無差別，因此第三部分的實驗采用了一段進水的方式。實驗結(jié)果表明，反應(yīng)器在HRT為9H、水溫為25℃，以及實際生活污水中COD、NH3N、TN、TP、SS的濃度分別為290～384、282～364、320～413、223～366、以及280～326MGL時，相應(yīng)的去除率分別達到904％、835％、551％、651％、以及937％。由于生物學(xué)方法除磷是有一定的局限性，處理水質(zhì)指標中除了TP濃度之外，其它水質(zhì)指標均可滿足城鎮(zhèn)污水處理廠污染物排放標準GB189182002中的一級排放標準。因此總體上看，本文設(shè)計的反應(yīng)器具有良好的去除性能。上述研究結(jié)果表明了本文設(shè)計的一體化裝置具有構(gòu)造簡單、結(jié)構(gòu)緊湊、管理方便、無回流系統(tǒng)等特點，并且在HRT僅為9H，且無二沉池的條件下，不僅具有很高的有機物、SS去除能力，而且還具有較好的脫氮除磷能力。因此，該新型一體化裝置在分散式生活污水處理領(lǐng)域具有良好的應(yīng)用前景。
