摘要
本试验采用规整填料塔对城市垃圾渗滤液中的氨氮进行了脱除研究。研究结果表明 ,在现场试验条件下 ,当渗滤液的水质在pH 7~ 9,CODCr2 0 0 0~ 10 0 0 0mg/l,BOD580 0~ 6 0 0 0mg/l,氨氮 10 0 0~ 5 0 0 0mg/l,悬浮物为 2 5 0mg/l时 ,吹脱塔的氨氮脱除效率可保持在 90 %以上 ,试验的药剂成本在 3元 /m3
A structured packing tower is used in the experiment for separating NH 3-H from the leachate of city waste landfill.The results show that the separating ratio of NH 3-H of the tower keeps up to 90%,the medicament cost is under 3 yuan per stere leachate when the leachate qualities are pH7~9,COD Cr 2~10kg/l,BOD 50.8~6kg/l,NH 3-H 1~5kg/l and SS 250mg/l at present experimental conditions.
