懸浮物對源水生物預(yù)處理裝置運行的影響和沖除
摘要: 探討了懸浮物對源水生物預(yù)處理裝置運行的影響程度和影響機理.中試設(shè)備模擬工程的生產(chǎn)條件,研究了懸浮物在填料上的積累規(guī)律,優(yōu)化出適合大型源水生物預(yù)處理工程的填料沖泥方法、沖泥強度、沖泥周期等;提出了源水生物預(yù)處理裝置運行時填料沖泥的判斷方法. Abstract: The influence extent and reason of suspended solid (SS) on polluted raw water bio-pretreatment op eration were studied in this article. On the condition of simulating an imperial project, the accumulation characteristics of silt on the packings in the biotreatment pond was analyzed, a modified aero-water backwashing method was optimized and now used to imperial project. Finally, it is proposed that the total NH4+ -N removal efficiency, water headloss and biofilm changes can be used as references to the SS backwashing cycle of polluted raw water biotreatment running. 作 者: 陳洪斌 梅翔 高廷耀 周增炎 CHEN Hong-bin MEI Xiang GAO Ting-yao ZHOU Zeng-yan 作者單位: 陳洪斌,高廷耀,周增炎,CHEN Hong-bin,GAO Ting-yao,ZHOU Zeng-yan(同濟大學(xué)環(huán)境科學(xué)與工程學(xué)院,)梅翔,MEI Xiang(南京大學(xué)環(huán)境科學(xué)與工程學(xué)院,)
