EFFECT OF HYDRAULIC LOADING ON LEACHATE TREATMENT BY THE AGED REFUSE REACTOR
-
摘要: 构建3个微曝气(0.1 L/min)矿化垃圾反应器进行渗滤液处理,研究较长时期内不同水力负荷对矿化垃圾处理渗滤液效果的影响。结果表明:随着水力负荷的增加,反应器对渗滤液中有机污染物和氮污染物的降解能力降低。在试验运行稳定阶段,水力负荷为28,42,56 L/(m3·d)时,COD平均去除率分别为88%、66%、56%;NH+4-N平均去除率分别为94%、90%、71%;TN平均去除率分别为52%、50%、45%。当水力负荷>42 L/(m3·d)时出现NO-2-N累积现象,且水力负荷越大NO-2-N累积越严重。建议微曝气矿化垃圾反应器处理渗滤液过程中水力负荷不宜大于42 L/(m3·d)。Abstract: The paper conducted the micro-aerated aged refuse reactor for leachate treatment and studied the longterm effect of hydraulic loading on leachate treatment． Ｒesults indicated that with the increase of hydraulic loading，the degradation of organics and nitrogen pollutants from leachate were reduced． In the stable stage，when the hydraulic loading reached 28，42， 56 L/( m3·d) ，the average COD removal were 88%，66%，56%，the average NH+ 4 －N removal were 94%，90%，71%，the average TN removal were 52%，50%，45%，respectively． However，once the hydraulic loading more than 42 L/( m3·d) ， the nitrite accumulation would appear and trend to be more serious with greater hydraulic loading． As a result，a proper hydraulic loading less than 42 L/( m3·d) was suggested during the leachate treatment by the micro-aerated aged refuse reactor．
