摘要:
为了考察垃圾渗滤液中有机物对其厌氧氨氧化反应的影响,保证晚期垃圾渗滤液的深度脱氮,采用短程硝化SBR联合厌氧氨氧化SBR(ASBR)两级系统处理氨氮为(2 000±100)mg/L、COD为(2 200±200)mg/L的实际晚期垃圾渗滤液进行试验研究.短程硝化SBR运行了100 d,亚硝酸盐积累率达到了95%以上.ASBR采用进水逐步加大渗滤液掺入比例的方式进行驯化.实验结果表明,随着掺入比例的增大,进水可降解COD增加到150 mg/L左右时,ASBR的氮负荷速率从1.20 kg/(m3·d)降到了0.28 kg/(m3·d),氮去除速率从1.10 kg/(m3·d)下降到了0.19 kg/(m3·d),表明系统趋于崩溃.当ASBR进水可降解COD再次降低到50 mg/L左右时,系统的厌氧氨氧化菌活性得到了恢复,最大的氮负荷速率和氮去除速率分别达到了1.55和1.20 kg/(m3·d).定量PCR试验表明,当系统的厌氧氨氧化菌活性得到恢复后,厌氧氨氧化菌占全细菌的比例达到了试验期间的最大值1.94%.
Abstract:
In order to investigate the effect of organics in the mature landfill leachate on the Anammox process treating mature landfill leachate, a combined process consisting of nitritation sequencing batch reactor(SBR)and anaerobic ammonium oxidation sequencing batch reactor(ASBR)was developed. The real mature landfill leachate with ammonia of(2000±100)mg/L and COD of(2200±200)mg/L was used in this study. After 100 days, the ratio of NO2-/NOxx- reached 95% or more in SBRni. ASBR was acclimated under the filling mode of increasing the mature landfill leachate gradually to supply the ammonia. The results show that the biodegradable COD is increased with the ratio of mature landfill leachate in the filling of ASBR. When the biodegradable COD in the filling increases to 150 mg/L, nitrogen loading rate(NLR)of ASBR decreases from 1.20 kg/(m3·d)to 0.28 kg/(m3·d), and nitrogen removal rate(NRR)decreases from 1.10 kg/(m3·d)to 0.19 kg/(m3·d). This indicates that the system tends to collapse. When the biodegradable COD decreases to 50 mg/L, the maximum NLR and NRR increases to 1.55 kg/(m3·d)and 1.20 kg/(m3·d), respectively, which indicates that the activity of Anammox is recovered. Besides, the quantitative PCR(polymerase chain reaction)shows that the proportion of Anammox in the bacteria increases to 1.94% when activity of Anammox becteria is recovered.
