研究了蛭石吸附污水中氨氮的吸附容量以及蛭石去除氨氮的等温吸附曲线，探讨了水中pH、温度、浓度对氨氮去除量的影响以及饱和蛭石再生后的效果，结果表明，蛭石的饱和和吸附量为20.83 mg/g；蛭石吸附量在pH2.0～6.0范围内随着pH的增大而增大，最佳pH为4.0～6.0温度在15℃～35℃范围内，吸附量随温度的升高减小；氨氮的去除率随着蛭石用量的增加而增加，这为蛭石作为一种新型填料提供了基础数据和理论依据。

This paper researched on NH_4-N capacity adsorption of vermiculite and adsorption isothem, and discussed the influence of pH、temperature、density on removal rate of NH_4-N and regeneration of saturated vermiculite. The experimental results showed that:saturated adsorption capacity of vermiculite is 20.83?mg/L; At pH level:2.0～6.0, Adsorption capacity of vermiculite increase with pH growing, and the optimal pH value:4.0～(6.0);At temperature value: 15℃～35℃, absorption capacity vermiculite inverse to temperature. This confirms basic parameters...
