3.結(jié)論
影響污泥產(chǎn)生的因素很多，如細(xì)胞溶解、隱性生長、生物捕食和解偶聯(lián)等，根據(jù)這些影響因素進(jìn)行適宜的工程設(shè)計(jì)可以極大地影響微生物的新陳代謝過程，從而降低剩余污泥的產(chǎn)量。污水好氧處理的污泥減量技術(shù)有兩個(gè)不足：需氧量的增加引起曝氣費(fèi)用的上升；營養(yǎng)物的釋放影響出水水質(zhì)，加重了脫氮除磷的負(fù)擔(dān)。長期運(yùn)行產(chǎn)生的生物適應(yīng)將給解偶聯(lián)劑的應(yīng)用帶來負(fù)面影響。這些研究說明了污泥減量的潛力很大，需要進(jìn)一步深入研究和開發(fā)污泥減量技術(shù)。
