摘 要: | 通过接种具有厌氧氨氧化性能的污泥,采用序批式厌氧反应器(ASBR)处理垃圾渗滤液,研究水力停留时间(HRT)、pH、温度等对厌氧氨氧化反应过程的影响并确定各因素的最佳控制范围。结果表明,在本试验条件下,HRT、pH和温度的适宜范围分别为24 h、7.5~8.5和35℃。在此条件下,进水NH~+_4-N浓度为150 mg/L,NO~-_2-N浓度为160 mg/L,COD浓度为300 mg/L时,出水NH~+_4-N、NO~-_2-N、TN、COD平均浓度分别为15.5 mg/L、0.01mg/L、43.2 mg/L和152.1 mg/L,相对应的平均去除率分别为89.7%、99.9%、86.1%和47.6%。

Abstract: | Anaerobic ammonium oxidized sludge is inoculated into the equipment of sequencing batch reactor (ASBR ) to dispose of the landfill leachate ,to study the effect of HRT ,pH and temperature to the anaerobic ammonium oxidation pro-cess and to determine the optimal controlling range .Results shows that ,the optimal HRT ,pH and temperature of the exper-iments are 24 h ,7 .5~8 .5 and 35 ℃ .Under such circumstance ,the influent concentration of NH4+ -N ,NO2- -N and COD are 150 mg/L ,160 mg/L and 300 mg/L ,and the average effluent concentration of NH4+ -N ,NO2- -N ,TN and COD are 15 .5 mg/L、0 .01 mg/L、43 .2 mg/L and 152 .1 mg/L ,with the average removal rate are 89 .7% ,99 .9% ,86 .1%and 47 .6% respectively . |
