摘　　要：针对猪场废水的危害和难处理性分析了温度、氨氮和COD对序批式生物膜反应器（SBBR）处理猪场厌氧消化液的除磷效果的影响。实验结果表明,（1）一定温度范围内温度升高不利于SBBR对厌氧消化液的除磷作用;（2）随着进水厌氧消化液氨氮浓度的增加,SBBR对总磷的去除效率从刚开始93.5%降到38.1%,氨氮浓度的升高不利于总磷的去除;（3）过量的碳源会导致反应器除磷效果下降,进水COD浓度宜在800~900 mg/L。With the hazard and intractability of swine wastewater,it was analyzed that the temperature,ammonia nitrogen and COD impact on the SBBR phosphorus removal of swine＇s anaerobic digestion.The results showed that：（1） in a certain range of temperatures,the higher of the temperature,the lower of phosphorus removal;（2） with the increase of the influent ammonia nitrogen concentration in anaerobic digestion,the rate of phosphorus removal reduced from 93.5% to 38.1%,so the increase of ammonia nitrogen concentration would result in the decrease of pH value,which was detrimental to the removal phosphorus;（3） an excessive amount of carbon source would decrease the efficiency of phosphorus removal,so the appropriate influent COD concentration arranged from 800 mg/L to 900 mg/L.
