2、綜合工藝集成技術

2.1、霧(wu)化充氧技術與(yu)浮(fu)選法

污(wu)水(shui)(shui)經閉路循(xun)環高(gao)速噴(pen)射入特殊湍流(liu)裝置形成(cheng)霧化，增大與(yu)空氣(qi)的(de)接(jie)觸(chu)界面，在一(yi)定壓(ya)力下溶(rong)(rong)合成(cheng)溶(rong)(rong)氣(qi)水(shui)(shui)，氣(qi)水(shui)(shui)溶(rong)(rong)解度達(da)到一(yi)定比例時，溶(rong)(rong)解氧(yang)(yang)濃度保持在12mg/l左右，部份污(wu)染(ran)物(wu)在高(gao)濃度溶(rong)(rong)解氧(yang)(yang)的(de)情況下發生化學反應，被直(zhi)接(jie)氧(yang)(yang)化分(fen)解。溶(rong)(rong)氣(qi)水(shui)(shui)通過釋(shi)放器將壓(ya)力迅速恢(hui)復到常壓(ya)，釋(shi)放出的(de)大量微(wei)(wei)氣(qi)泡(pao)(pao)吸咐凝聚于(yu)污(wu)水(shui)(shui)中(zhong)懸浮(fu)(fu)雜質上，造成(cheng)雜質整體比重小于(yu)污(wu)水(shui)(shui)的(de)狀態，依靠(kao)微(wei)(wei)氣(qi)泡(pao)(pao)的(de)浮(fu)(fu)力，使(shi)其上浮(fu)(fu)至水(shui)(shui)面，從而達(da)到固(gu)液分(fen)離的(de)目(mu)的(de)。

2.2、生物流化床原理(li)

生(sheng)(sheng)物(wu)流(liu)(liu)化(hua)(hua)床內裝有(you)特種懸浮(fu)狀可流(liu)(liu)化(hua)(hua)性(xing)生(sheng)(sheng)物(wu)載體(ti)，載體(ti)利用流(liu)(liu)體(ti)動力學原理使(shi)其懸浮(fu)流(liu)(liu)化(hua)(hua)，溶(rong)氣水(shui)(shui)釋放的微(wei)氣泡吸(xi)附在載體(ti)上，向好氧微(wei)生(sheng)(sheng)物(wu)提(ti)供(gong)充足的溶(rong)解氧。在特定(ding)條件下，污(wu)水(shui)(shui)作為(wei)微(wei)生(sheng)(sheng)物(wu)培(pei)養基，培(pei)養出微(wei)生(sheng)(sheng)物(wu)菌群，形成以最適宜增殖的微(wei)生(sheng)(sheng)物(wu)為(wei)中(zhong)心，與多(duo)種多(duo)樣生(sheng)(sheng)物(wu)相(xiang)結(jie)合的一個生(sheng)(sheng)態系，并吸(xi)附凝聚大(da)量(liang)的微(wei)生(sheng)(sheng)物(wu)菌膠體(ti)，固定(ding)在懸浮(fu)載體(ti)上，溶(rong)解性(xing)有(you)機(ji)質在好氧微(wei)生(sheng)(sheng)物(wu)作用下，促進有(you)機(ji)質的生(sheng)(sheng)化(hua)(hua)分(fen)解進程，使(shi)有(you)機(ji)質轉化(hua)(hua)成無機(ji)質。

2.3、A/OWH工藝與除磷脫(tuo)氮

因為(wei)好氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)無(wu)法(fa)(fa)徹底去除污(wu)(wu)水(shui)中的(de)(de)(de)(de)(de)磷和氮，在(zai)(zai)設計污(wu)(wu)水(shui)處理(li)方案時(shi)(shi)，一(yi)定要分別選用(yong)(yong)厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)與好氧(yang)(yang)(yang)(yang)工藝(yi)（A/O或(huo)A2/O）相(xiang)搭(da)配，并(bing)要求一(yi)定的(de)(de)(de)(de)(de)回流比(bi)，這樣必然導致水(shui)力停留時(shi)(shi)間(jian)長，而(er)且難以控制厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)和好氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)之間(jian)的(de)(de)(de)(de)(de)動(dong)(dong)態(tai)平衡，無(wu)法(fa)(fa)消除磷的(de)(de)(de)(de)(de)釋放與吸(xi)(xi)收(shou)之間(jian)的(de)(de)(de)(de)(de)時(shi)(shi)間(jian)差。A/OWH工藝(yi)是指在(zai)(zai)同一(yi)裝置內(nei)混合存(cun)在(zai)(zai)兩種相(xiang)同密度、其(qi)(qi)它物(wu)(wu)(wu)理(li)特性(xing)不同的(de)(de)(de)(de)(de)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)載體(ti)(ti)，使(shi)其(qi)(qi)分別適合厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)微(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)和好氧(yang)(yang)(yang)(yang)微(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)的(de)(de)(de)(de)(de)生(sheng)(sheng)(sheng)(sheng)長條件，由(you)于A/O混合，厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)與好氧(yang)(yang)(yang)(yang)同步進行。厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)載體(ti)(ti)具(ju)有極(ji)大的(de)(de)(de)(de)(de)比(bi)表(biao)面積，工作時(shi)(shi)載體(ti)(ti)表(biao)面首先凝聚著(zhu)好氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)，并(bing)由(you)里向(xiang)(xiang)外逐(zhu)漸堵塞(sai)載體(ti)(ti)空(kong)間(jian)，形成(cheng)一(yi)個(ge)碩大的(de)(de)(de)(de)(de)封閉式的(de)(de)(de)(de)(de)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)團，這時(shi)(shi)外部(bu)(bu)溶(rong)解氧(yang)(yang)(yang)(yang)無(wu)法(fa)(fa)滲透進去，造成(cheng)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)團內(nei)部(bu)(bu)厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)環境(jing)，在(zai)(zai)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)團中心好氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)逐(zhu)步被(bei)厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)所(suo)替代，厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)活性(xing)不斷增(zeng)強，同樣，厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)菌從(cong)里向(xiang)(xiang)外逐(zhu)漸分解掉生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)團內(nei)部(bu)(bu)被(bei)包裹(guo)的(de)(de)(de)(de)(de)有機(ji)質(zhi)(zhi)，直(zhi)到(dao)整個(ge)菌膠體(ti)(ti)從(cong)載體(ti)(ti)上脫落。然后，隨著(zhu)載體(ti)(ti)的(de)(de)(de)(de)(de)懸浮運動(dong)(dong)及流體(ti)(ti)的(de)(de)(de)(de)(de)推(tui)動(dong)(dong)力，包裹(guo)在(zai)(zai)里面的(de)(de)(de)(de)(de)水(shui)質(zhi)(zhi)與外部(bu)(bu)的(de)(de)(de)(de)(de)水(shui)質(zhi)(zhi)自(zi)動(dong)(dong)交(jiao)換，重復A/O交(jiao)替過(guo)程。A/OWH工藝(yi)就是利用(yong)(yong)除磷菌在(zai)(zai)厭(yan)(yan)(yan)(yan)(yan)(yan)(yan)氧(yang)(yang)(yang)(yang)條件下釋放磷，在(zai)(zai)好氧(yang)(yang)(yang)(yang)條件下吸(xi)(xi)收(shou)磷的(de)(de)(de)(de)(de)多次(ci)交(jiao)替過(guo)程，從(cong)而(er)達到(dao)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)除磷的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。同樣氨氮在(zai)(zai)有氧(yang)(yang)(yang)(yang)存(cun)在(zai)(zai)的(de)(de)(de)(de)(de)環境(jing)下，通過(guo)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)硝化過(guo)程將污(wu)(wu)水(shui)中的(de)(de)(de)(de)(de)有機(ji)氮和氨氮氧(yang)(yang)(yang)(yang)化為(wei)硝態(tai)氮，在(zai)(zai)缺氧(yang)(yang)(yang)(yang)環境(jing)下通過(guo)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)的(de)(de)(de)(de)(de)硝化過(guo)程將硝態(tai)氮還(huan)原(yuan)為(wei)氮氣從(cong)水(shui)中逸(yi)出，部(bu)(bu)份(fen)氨氮被(bei)微(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)新陳代謝所(suo)利用(yong)(yong)而(er)變(bian)成(cheng)細胞組成(cheng)部(bu)(bu)份(fen)，并(bing)逐(zhu)漸老化轉變(bian)成(cheng)剩(sheng)余污(wu)(wu)泥從(cong)系統中排出。

2.4、重力過濾法

污水(shui)經(jing)生化(hua)和物(wu)化(hua)的共同作用，溶解性(xing)有機物(wu)和比重較(jiao)輕(qing)的懸(xuan)浮(fu)物(wu)得(de)(de)到徹底去除，部份比重較(jiao)大、難分解的固體(ti)物(wu)仍存(cun)在水(shui)中(zhong)，PS型生物(wu)流(liu)(liu)化(hua)床污水(shui)處理設備利用流(liu)(liu)化(hua)區出水(shui)的重力流(liu)(liu)過(guo)(guo)濾(lv)(lv)(lv)(lv)，過(guo)(guo)濾(lv)(lv)(lv)(lv)時以石英砂（或纖維球(qiu)、活(huo)性(xing)炭、過(guo)(guo)濾(lv)(lv)(lv)(lv)膜等）截留(liu)水(shui)中(zhong)固體(ti)雜質或菌膠體(ti)，反洗時水(shui)流(liu)(liu)逆(ni)向通過(guo)(guo)濾(lv)(lv)(lv)(lv)料(liao)(liao)層，使濾(lv)(lv)(lv)(lv)料(liao)(liao)層膨脹(zhang)懸(xuan)浮(fu)，借水(shui)流(liu)(liu)剪(jian)切和顆粒(li)濾(lv)(lv)(lv)(lv)料(liao)(liao)間(jian)的碰撞摩擦力清洗濾(lv)(lv)(lv)(lv)料(liao)(liao)層，過(guo)(guo)濾(lv)(lv)(lv)(lv)和反洗兩(liang)個過(guo)(guo)程(cheng)交替(ti)進行，從(cong)而(er)使水(shui)最終獲得(de)(de)澄清。

3、兼具好氧與厭氧的懸浮填料（AOF復合填料）
