【導(dǎo)讀】A2O-MBR反應(yīng)器在17LMH流量下連續(xù)運行210天。然后在兩周內(nèi)逐步提高設(shè)。熱化學(xué)消化污泥運行在一個固定的pH. 值和溫度(75℃)下，可溶解的COD含量為25%。過程被送回厭氧罐。污泥的厭氧消化對COD和總磷的去除沒有任何影響。運行中,MBR通過膜過濾壓差保持相對穩(wěn)定。研究結(jié)果表明,所提出的流程配置在不降低處理。水水質(zhì)的情況下，有可能減少剩余污泥的產(chǎn)生。剩余污泥的減少和脫氮除磷是污水處理廠兩個相關(guān)的重要課題。MBR過程由于具有更長。的污泥齡，所以處理程度更高,污泥的產(chǎn)量相對較低。泥的產(chǎn)量大概降低28-68%，這取決于所用的污泥齡。在MBR反應(yīng)器內(nèi)這個問題可以通過引進污泥分解技術(shù)來解決。解和生化處理是污泥減量化處理的基礎(chǔ)。是在有氧與缺氧交替的情況下通過聚磷微生物的過度攝取而達到的。此外，工業(yè)化對磷資源的需求在不斷地增長，在許。較低的轉(zhuǎn)速混合，以保證混合物中的懸浮固體始終處于懸浮狀態(tài)。濾膜的工作面積為。第38天時MLSS的濃度已經(jīng)達到8100mg/L。
