【摘要】：為考察生物炭三維電極對(duì)水中氨氮的作用機(jī)制,以生物炭為反應(yīng)介質(zhì)構(gòu)建三維電極反應(yīng)器,研究其對(duì)無氯水體中氨氮的去除效果,并探究水中氨氮的轉(zhuǎn)化機(jī)理.結(jié)果表明,生物炭三維電極可以在短時(shí)間內(nèi)對(duì)氨氮高效去除(氨氮初始質(zhì)量濃度ρ0=100 mg/L,t=3 h,η=45.72%),去除過程符合一級(jí)動(dòng)力學(xué)模型,且氨氮的轉(zhuǎn)化過程是一個(gè)消耗OH-的反應(yīng)過程.反應(yīng)器系統(tǒng)中反應(yīng)產(chǎn)物分析證明,生物炭吸附作用對(duì)氨氮去除貢獻(xiàn)甚微,氨氮主要通過直接氧化和間接氧化作用得以去除,最終轉(zhuǎn)化為等量的N2和NO3--N而得以去除.
[Abstract]:In order to investigate the action mechanism of biochar three dimensional electrode on ammonia nitrogen in water, a three dimensional electrode reactor was constructed with biological carbon as reaction medium to study the removal effect of ammonia nitrogen in chlorine free water and the mechanism of ammonia nitrogen conversion in water. The results showed that the removal of ammonia nitrogen (100 mg 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) of ammonia nitrogen was highly effective in a short period of time, and the removal process was in accordance with the first-order kinetic model, and the conversion process of ammonia nitrogen was an OH- consuming reaction process. The analysis of reaction products in the reactor system showed that biochar adsorption had little contribution to ammonia nitrogen removal. Ammonia nitrogen was removed mainly by direct oxidation and indirect oxidation, and then converted to the same amount of N _ 2 and no _ 3-N.
