摘要:以某垃圾填埋場(chǎng)老齡垃圾滲濾液為處理對(duì)象,構(gòu)建了一套前置亞硝化反硝化-部分亞硝化(PN)/厭氧氨氧化(A)工藝的中試系統(tǒng),探究其對(duì)該老齡垃圾滲濾液低碳脫氮處理的快速啟動(dòng)與適用性。結(jié)果表明,在已有培養(yǎng)成熟的厭氧氨氧化菌種基礎(chǔ)上,該中試系統(tǒng)僅用23 d就達(dá)到了15 kg/d的氨氮去除量;通過前置反硝化去除滲濾液中的大部分可生化有機(jī)物后,系統(tǒng)對(duì)老齡垃圾滲濾液中氨氮、總氮和COD的平均去除率分別可達(dá)到95.1%、94.3%、67.9%;經(jīng)濟(jì)核算結(jié)果表明,該工藝的處理成本(以去除NH4+-N計(jì))僅為9.3 元/kg,遠(yuǎn)低于硝化-反硝化工藝。
Abstract:This paper constructed a pilot-scale system consisting of pre-nitritation/denitrification, partial nitritation (PN) and Anammox (A), and investigated its rapid start-up and applicability for removing nitrogen in the aged landfill leachate with low organic pollutants concentration from a landfill. Seeded with existing mature Anammox bacteria, the pilot system achieved a removal of 15 kg/d ammonia nitrogen in just 23 days. After pre-denitrification to remove most of the biodegradable organic pollutants in the leachate, the average removal rates of ammonia nitrogen, total nitrogen, and COD from the aged landfill leachate reached 95.1%, 94.3% and 67.9% respectively. The economic calculations showed that the treatment cost of this process was only 9.3 yuan/kg, which was significantly lower than that of the nitrification-denitrification process.
