曝氣機的安裝維護

 微孔(kong)(kong)(kong)曝氣(qi)(qi)管(guan)(guan)(guan)的(de)(de)形式(shi)有(you)很(hen)多(duo)，目前較為常用(yong)(yong)(yong)(yong)的(de)(de)有(you)兩種(zhong)(zhong)：一(yi)種(zhong)(zhong)是由(you)粗瓷或(huo)剛玉等(deng)燒(shao)結(jie)而成(cheng)(cheng)的(de)(de)普通曝氣(qi)(qi)管(guan)(guan)(guan)，這(zhe)種(zhong)(zhong)管(guan)(guan)(guan)壁(bi)(bi)(bi)在(zai)燒(shao)結(jie)過(guo)程(cheng)中(zhong)產生(sheng)許多(duo)極微小(xiao)的(de)(de)孔(kong)(kong)(kong)隙，它(ta)的(de)(de)主要(yao)特點(dian)(dian)是能產生(sheng)微小(xiao)的(de)(de)氣(qi)(qi)泡(pao)，氣(qi)(qi)泡(pao)直(zhi)徑(jing)(jing)(jing)約0.1～0.2mm，氣(qi)(qi)、液接觸(chu)面(mian)積大(da)，氧(yang)(yang)(yang)利(li)(li)用(yong)(yong)(yong)(yong)率(lv)高，一(yi)般(ban)可達(da)到20～25%;其缺(que)點(dian)(dian)是氣(qi)(qi)壓損失較大(da)，易(yi)堵塞(sai)，送入(ru)的(de)(de)空(kong)氣(qi)(qi)需經¬過(guo)濾處理，易(yi)損壞，一(yi)旦(dan)損壞，氧(yang)(yang)(yang)利(li)(li)用(yong)(yong)(yong)(yong)率(lv)就(jiu)開(kai)始快速下(xia)降。另一(yi)種(zhong)(zhong)是管(guan)(guan)(guan)式(shi)膜(mo)(mo)片(pian)(pian)微孔(kong)(kong)(kong)曝氣(qi)(qi)管(guan)(guan)(guan)。這(zhe)種(zhong)(zhong)曝氣(qi)(qi)管(guan)(guan)(guan)的(de)(de)安裝方(fang)式(shi)與前一(yi)種(zhong)(zhong)基本(ben)一(yi)樣，但其自(zi)(zi)身的(de)(de)結(jie)構卻有(you)很(hen)大(da)的(de)(de)區別，它(ta)是由(you)一(yi)個用(yong)(yong)(yong)(yong)ABS或(huo)UPVC制成(cheng)(cheng)的(de)(de)管(guan)(guan)(guan)子作(zuo)(zuo)為布氣(qi)(qi)管(guan)(guan)(guan)，管(guan)(guan)(guan)壁(bi)(bi)(bi)上開(kai)有(you)通風孔(kong)(kong)(kong)，布氣(qi)(qi)管(guan)(guan)(guan)外周覆蓋(gai)著合(he)成(cheng)(cheng)橡(xiang)膠制成(cheng)(cheng)的(de)(de)膜(mo)(mo)片(pian)(pian)，膜(mo)(mo)片(pian)(pian)被金屬卡子固(gu)定在(zai)管(guan)(guan)(guan)子上。在(zai)合(he)成(cheng)(cheng)橡(xiang)膠膜(mo)(mo)片(pian)(pian)上用(yong)(yong)(yong)(yong)激光等(deng)方(fang)法打出均(jun)勻分布的(de)(de)孔(kong)(kong)(kong)眼(yan)。曝氣(qi)(qi)時，空(kong)氣(qi)(qi)通過(guo)管(guan)(guan)(guan)壁(bi)(bi)(bi)上的(de)(de)通氣(qi)(qi)孔(kong)(kong)(kong)進入(ru)膜(mo)(mo)片(pian)(pian)與管(guan)(guan)(guan)壁(bi)(bi)(bi)之間(jian)，在(zai)壓縮空(kong)氣(qi)(qi)的(de)(de)作(zuo)(zuo)用(yong)(yong)(yong)(yong)下(xia)，使膜(mo)(mo)片(pian)(pian)微微鼓起，孔(kong)(kong)(kong)眼(yan)張(zhang)開(kai)，達(da)到布氣(qi)(qi)擴(kuo)散(san)的(de)(de)目的(de)(de)。停止(zhi)供氣(qi)(qi)，氣(qi)(qi)壓消(xiao)失后，膜(mo)(mo)片(pian)(pian)本(ben)身在(zai)彈性作(zuo)(zuo)用(yong)(yong)(yong)(yong)下(xia)使孔(kong)(kong)(kong)眼(yan)自(zi)(zi)動閉合(he)，由(you)于水(shui)壓的(de)(de)作(zuo)(zuo)用(yong)(yong)(yong)(yong)，膜(mo)(mo)片(pian)(pian)壓實在(zai)管(guan)(guan)(guan)壁(bi)(bi)(bi)上。因此(ci)(ci)，污水(shui)不會(hui)倒流而堵塞(sai)孔(kong)(kong)(kong)眼(yan)。但由(you)于這(zhe)種(zhong)(zhong)膜(mo)(mo)片(pian)(pian)的(de)(de)開(kai)孔(kong)(kong)(kong)直(zhi)徑(jing)(jing)(jing)直(zhi)接影(ying)響到氧(yang)(yang)(yang)的(de)(de)利(li)(li)用(yong)(yong)(yong)(yong)率(lv)，因此(ci)(ci)，開(kai)孔(kong)(kong)(kong)直(zhi)徑(jing)(jing)(jing)應適當。開(kai)孔(kong)(kong)(kong)直(zhi)徑(jing)(jing)(jing)過(guo)大(da)，氧(yang)(yang)(yang)的(de)(de)利(li)(li)用(yong)(yong)(yong)(yong)率(lv)較低，開(kai)孔(kong)(kong)(kong)直(zhi)徑(jing)(jing)(jing)過(guo)小(xiao)，氧(yang)(yang)(yang)利(li)(li)用(yong)(yong)(yong)(yong)率(lv)高，但阻力(li)增(zeng)大(da)。

曝氣設備適用范圍廣，可用于工業廢水處理和生活污水處理，也可用于河道、湖泊等地表水的處理、地下水除鐵除錳的給水處理；可用于活性污泥法曝氣池曝氣攪拌、調節池均質攪拌、污水處理廠的曝氣沉砂、好氧池曝氣、混凝池攪拌、化學法的反應池攪拌均合等場合。正確的安裝維護曝氣機以免損傷!
 曝氣機是通過散氣葉輪，將“微氣泡”直接注入未經處理的污水中，在混凝劑和絮凝劑的共同作用下，懸浮物發生物理絮凝和化學絮凝，從而形成大的懸浮物絮團，在氣泡群的浮升作用下“絮團”浮上液面形成浮渣，利用刮渣機從水中分離；不需要清理噴嘴，不會發生阻塞現象。
安裝維護：
  本設備可根據曝氣池結構特點、待處理水的水量、水質指標變化等任意調節空氣量、靈活選擇安裝位置、布置方式、噴射角度、潛水深度等。本設備通常將射流器安裝在散流器上，潛水泵單獨布置，并采用軟管連接，以便水泵吊出維護，避免設備維護時放空池水，同時，搬運、吊裝、拆卸更方便。
  由于(yu)射流(liu)(liu)器(qi)和散流(liu)(liu)器(qi)屬于(yu)靜(jing)止設(she)(she)備，無須運轉維護，潛水(shui)泵選用專業廠家產品，質量易于(yu)保證，因此，本設(she)(she)備基本不需(xu)要頻繁(fan)維護，一般對潛水(shui)泵每年例行維護一次。
