class="NyNewsdetail_con"> <div>　　DTRO碟管式反滲透膜技術是現(xiàn)在垃圾滲濾液處理中有用的技能之一，雖然這個技能本身具有必定的抗污染性，但是在整個出產(chǎn)運轉(zhuǎn)過程中假如它長時間沒有得到有用的維護，再加上水質(zhì)中的污染物長時間的堆積，膜污染就會發(fā)生。此刻膜的透過率會減小，膜通量下降，膜的壽數(shù)大大縮減，同時也使出產(chǎn)運轉(zhuǎn)本錢不斷的進步。所以在整個工藝運轉(zhuǎn)過程中，要根據(jù)膜的工藝、浸透量、膜的功能等因素做好分析，并加以正確的方法對DTRO碟管式反滲透膜進行維護改進。</div><div align="center"><img src="http://img70.hbzhan.com/9/20191220/637124546302409923176.png" alt="DTRO碟管式反滲透膜" width="400" height="271" align="" border="0" /></div><div>　　因碟管式反浸透膜技能在處理過程中要求進水為酸性，因而需要對要處理的滲濾液參加工業(yè)鹽酸以調(diào)節(jié)其PH值，經(jīng)過對膜材料進行實驗，確認PH的范圍。使膜始終處于偏酸的作業(yè)情況下，才能確保膜的壽數(shù)到達5年以上。<br /> </div><div>　　關于調(diào)整PH之后的廢水要進行水溫的操控，一般水溫要求操控在5度以上，才能確保膜片運轉(zhuǎn)效率高。在操作壓力必定的條件下，溫度的升高可以下降膜污染的速度。<br /> </div><div>　　DTRO碟管式反滲透膜要進行定時的清洗與維護，但在清洗過程中要注意操作壓力對膜污染的影響，在膜運轉(zhuǎn)初級階段，由于膜與溶質(zhì)之間的吸附效果較大，此刻進步操作壓力可以使更多的溶質(zhì)分子浸透過去，進而使膜污染下降。然而操作壓力的不斷添加會導致膠體物質(zhì)在膜外表的沉積速度添加，這樣又進一步加快了膜污染的速度。因而，在實際操作過程中關于操作壓力確實認要根據(jù)實際情況合理選擇，并且為了更好的操控膜通量，應當設定相應的戒備值，當跨膜壓差到達必定值時，進行膜清洗。</div>
