ASBR处理中晚期垃圾渗滤液中试研究

通过ASBR中试反应器处理某垃圾填埋场内垃圾渗滤液,在不调节pH的条件下,探讨了水力停留时间、搅拌方式和进水氨氮浓度对ASBR反应器处理中晚期垃圾渗滤液的影响。结果表明：当HRT=4 d时,间歇搅拌和氨氮浓度低于800 mg/L时,ASBR反应器达到最佳,ASBR反应器对COD、TN和SS的平均去除率为32.04%、10.5%和32.63%,渗滤液可生化性由0.39提高到0.46;进水氨氮浓度大于800 mg/L,即FA〉62.59 mg/L时会抑制有机物的降解。

Pliot Study on the Treatment of Landfill Leachate with ASBR Technology

Through the test of the actual landfill leachate from one landfill with ASBR technology,pH value of not regulating conditions,discussed hydraulic residence time（HRT）,the way of stir and influent concentration of ammonia nitrogen how to influence the test of the actual landfill leachate with ASBR,the results of the pliot scale experimept are as follows： when HRT=4 d,intermittent stir and concentration of ammonia nitrogen are less than 800 mg/L,ASBR reactor is best,the average removal rate of ASBR reactor to COD,TN and SS respectively was 32.04%,10.5% and 32.63%;biodegradability of leachate raise from the 0.39 to 0.46 after ASBR teated;when the concentration of ammonia nitrogen is more than 800 mg/L,FA62.59 mg/L,organic degeneration will be inhibited.
