摘要：试验研究了在不同浓度微生物制剂、不同氨氮质量浓度、不同温度与pH等条件下，复合微生物制剂去除氨氮的效果。试验表明，复合微生物制剂对改善水质，降低水体中的氨氮具有明显作用。结果显示，使用复合微生制剂的最佳质量浓度是10.00 mg/L，在氨氮质量浓度为4.44 mg/L、温度为35 ℃时制剂的氨氮去除率最高，在碱性的环境中去除氨氮效果优于酸性环境。

Abstract：The effects of compound microorganism preparation on removing ammonia nitrogen were studied by different conditions. The results showed the compound microorganism preparation improved water quality and decreased significantly the ammonia nitrogen in water. The compound microorganism preparation of 10 mg/L was the most optimal quality concentration and the effects of decreasing ammonia nitrogen was the best as the quality concentration of ammonia nitrogen was lower than 4.44 mg/L ,and were the better at temperature of 35 ℃ and the alkaline water
