一、結構特點及用途

　　膜片(pian)(pian)(pian)式微孔(kong)曝氣(qi)(qi)(qi)(qi)器主要(yao)由曝氣(qi)(qi)(qi)(qi)底座(zuo)、上螺旋壓(ya)蓋、空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)均流(liu)板、合成(cheng)(cheng)(cheng)橡(xiang)膠膜片(pian)(pian)(pian)等組成(cheng)(cheng)(cheng)，合成(cheng)(cheng)(cheng)橡(xiang)膠膜片(pian)(pian)(pian)上開(kai)有2100—2500個按一(yi)定規則排列的開(kai)閉式孔(kong)眼，充氣(qi)(qi)(qi)(qi)時，空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)通過布氣(qi)(qi)(qi)(qi)管道，空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)均流(liu)板均勻進(jin)入橡(xiang)膠膜片(pian)(pian)(pian)之(zhi)間，在空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)壓(ya)力作用(yong)下(xia)(xia)，使膜片(pian)(pian)(pian)微微鼓起，孔(kong)眼張開(kai)，達到布氣(qi)(qi)(qi)(qi)擴散的目的。停(ting)止供氣(qi)(qi)(qi)(qi)時，由于(yu)膜片(pian)(pian)(pian)和空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)均流(liu)板之(zhi)間壓(ya)力漸漸下(xia)(xia)降，使孔(kong)眼逐漸閉合，當壓(ya)力全部消失后，由于(yu)水壓(ya)作用(yong)和膜片(pian)(pian)(pian)本身的回彈作用(yong)，將膜片(pian)(pian)(pian)壓(ya)實于(yu)空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)均流(liu)板上，鑒于(yu)上述(shu)構造以及(ji)膜片(pian)(pian)(pian)本身的良好彈性(xing)，曝氣(qi)(qi)(qi)(qi)池中的混合液(ye)不(bu)可能倒灌，因(yin)此，不(bu)會沾污孔(kong)眼。另一(yi)方面，當孔(kong)眼開(kai)啟時，由于(yu)橡(xiang)膠的彈性(xing)作用(yong)，空(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)中所含的少量(liang)塵埃(ai)，也(ye)不(bu)會造成(cheng)(cheng)(cheng)曝氣(qi)(qi)(qi)(qi)器的孔(kong)隙堵塞(sai)。

　　該曝(pu)氣器具有耐腐蝕、布氣均勻、微孔可變不堵塞、氧(yang)利用(yong)率(lv)和動力(li)效(xiao)率(lv)高等特點。應(ying)用(yong)于市政及工業廢水中(zhong)曝(pu)氣及生化處理(li)工程(cheng)中(zhong)。

二、技術指標

三、布置、安裝

1、曝氣器均勻布置(zhi)于曝氣池(chi)底(di)，其表面距池(chi)底(di)約200-300mm，間距按設計(ji)要求均勻布置(zhi)。

2、進氣管(guan)的設(she)置(zhi)應考慮壓力平衡，每組(zu)支管(guan)應設(she)置(zhi)閥(fa)門(men)，便于調(diao)節空氣量(liang)，并在支管(guan)末(mo)端(duan)設(she)置(zhi)氣壓排(pai)水管(guan)，以排(pai)除(chu)因安裝調(diao)試或(huo)停機(ji)時流入(ru)管(guan)內的積水。
