摘要
研究采用吹脱—水解酸化—SBR工艺处理含高浓度氨氮的垃圾渗滤液。结果表明,采用吹脱预处理可去除废水中60%以上的氨氮,有利于后续生物脱氮和脱碳的进行。生物水解酸化处理在降低废水CODCr值的同时,可以提高废水的可生化性。该方法将曝气期分为二段,并设置缺氧反硝化期,可明显提高氨氮的去除率。
Using ablution-hydrolysis acidification-SBR process treat landfill leachate with highly concentrated amino nitrogen. The results show that amino nitrogen over 60% in wastewater is moved using ablution-hydrolysis acidification-SBR process. The process is useful for tail biological method to denitrification and decarbonization. The processing of biological hydrolysis-acidification decreases concentration of CODCr and improves possibility of the biological degrativities of wastewater. This method set aeration time of two step and oxygen-free denitrification time, obviously improve moved rate of amino nitrogen.
