摘要:為了推動(dòng)城鎮(zhèn)污水低碳高效脫氮，提出了一種雙區(qū)序批式短程硝化厭氧氨氧化脫氮技術(shù)。通過設(shè)置底部厭氧氨氧化顆粒污泥區(qū)和上部絮體污泥短程硝化區(qū)，實(shí)現(xiàn)了高速率脫氮。在進(jìn)水無有機(jī)物、氨氮濃度為58.18 mg/L以及水力停留時(shí)間為1.66 h的情況下，容積氮去除速率高達(dá)675 mg/（L?d），出水總氮濃度為13.19 mg/L。宏基因組分析結(jié)果表明，絮體污泥中氨氧化菌相對(duì)豐度為14.70%，而氨氧化菌與亞硝酸鹽氧化菌相對(duì)豐度之比為10.77，亞硝態(tài)氮積累率為81%。顆粒污泥中厭氧氨氧化菌相對(duì)豐度為23.22%，總氮去除速率為7.53 mg/（gMLSS?h）。該技術(shù)脫氮速率高、占地面積小，有望為用地緊張的城鎮(zhèn)中心污水處理廠減污降碳升級(jí)改造提供新的技術(shù)選擇。
Abstract:To promote low-carbon and efficient nitrogen removal from urban wastewater, a two- zone sequential batch nitritation and Anammox technology was proposed. By establishing a bottom Anammox granular sludge zone and an upper floc sludge nitritation zone, high-rate nitrogen removal was achieved. Under the conditions of no organic matter in the influent, ammonia nitrogen concentration of 58.18 mg/L, and hydraulic retention time of 1.66 hours, the nitrogen removal rate reached 675 mg/(L-d), with an effluent total nitrogen concentration of 13.19 mg/L. Metagenomic results indicated that the relative abundance of ammonia-oxidizing bacteria (AOB) in the floc sludge was 14.70%, while the abundance ratio of AOB to nitrite-oxidizing bacteria (NOB) was 10.77, with a nitrite accumulation rate (NAR) of 81%. The relative abundance of Anammox bacteria in the granular sludge was 23.22%, and the total nitrogen removal rate was 7.53 mg/(gMLSS·h). This technology, with its high nitrogen removal rate and small footprint, is expected to provide a new technical option for reducing pollution and carbon emission in upgrade of wastewater treatment plants in urban centers with limited land availability.
