| 摘 要： | 为木炭运用于沼液吸附处理及循环利用提供理论依据,在沼液中加入木炭与活性炭进行静态吸附试验,分析木炭对沼液中氨态氮(NH4+-N)、总磷(TP)、化学需氧量(COD)的吸附效果。结果表明:木炭对沼液中高浓度的NH4+-N、TP和COD均有一定的吸附作用,其吸附容量分别为2.19mg/g、0.5mg/g和18mg/g;活性炭对NH4+-N的吸附效果比木炭好,其饱和吸附容量是木炭的1.73倍;木炭与活性炭对沼液中TP和COD的吸附效果相差不大;木炭可以作为吸附材料处理沼液中的NH4+-N、TP及COD。

| Abstract: | A static adsorption experiment was conducted by putting charcoal and activated carbon into biogas and the absorption levels of NH+4-N,TP and COD in the biogas were analyzed to provide theoretical basis for charcoal’s application in biogas adsorption and recycling.The results showed that charcoal has certain absorption on NH+4-N,TP and COD of high concentrations in biogas and the absorption capacities are 2.19 mg/g,0.5 mg/g and 18 mg/g respectively.However,activated carbon has higher absorption level on NH+4-N than charcoal by 0.73 times;And their absorption capacities on TP and COD are more or less the same;charcoal can be used for NH+4-N,TP and COD treatment in biogas as adsorbing material. |
