为提高猪场沼液中氨氮和总磷的去除效果，采用铁碳微电解法预处理方法，在常温条件下研究铁和碳的等温吸附及吸附动力学，确定铁和碳的最大吸附量，消除其在微电解作用下的吸附影响。结果表明：活性炭粉对氨氮、总磷吸附符合 Freundlich 方程，铁粉对氨氮、总磷的吸附符合 Langmuir 方程；准二级动力学模型适用铁粉及活性碳粉对氨氮及总磷的吸附，铁和碳在猪场沼液中吸附2 h 可达饱和吸附。当（20±1）℃时，铁碳比为1∶1，pH 为3，反应时间为120 min 时去除效果较好，氨氮的去除率为34．01％，总磷的去除率为97．23％。

To enhance the removal efficiency of nitrogen and phosphorus in piggery biogas slurry,iron carbon was used as the electrode of the micro-electrolysis to study the removal of nitrogen and phosphorus in piggery biogas slurry.The isothermal adsorption and the adsorption kinetics of the iron and the carbon were studied and analyzed sparely in the ambient temperature,so that the maximum absorption capacity could be tested,then the effect of absorption could be removed under the micro-electrolysis condition.As the results showed,the adsorption isotherms of activated carbon powder and iron powder accorded with Freundlich equation and Langmuir equation respectively.Pseudo-second order kinetic model was applicable for adsorption of iron powder and activated carbon powder to ammonia nitrogen and phosphorus.The saturated absorption accomplished when the iron and the carbon were dip in the piggery biogas slurry separately to 24 hours,when T=(20±1)℃,iron carbon mass ratio reached 1∶1,pH=3,reaction time reached 120 min,the most reasonable removal result was found,that is,the removal ratio of phosphor was 97.23%,ammonia nitrogen was 34.01%.
