| 摘 要： | 研究了膨胀蛭石对氨氮的吸附容量及pH、温度、进水氨氮浓度和膨胀蛭石用量对氨氮去除率的影响.结果表明,膨胀蛭石对氨氮的饱和吸附量为17.32 mg.g-1;氨氮去除率在pH 4.0~7.0范围内大于65%;在进水氨氮浓度低于200 mg.L-1时,氨氮去除率随着进水氨氮浓度增加而增大,为膨胀蛭石作为一种新型填料提供了基础数据和理论依据.

| Abstract: | The present study was conducted to determine the adsorption capacity of NH4-N by expanded vermiculite and to test the influence of pH value,temperature,ammonium concentration and applied quantity of expanded vermiculite minerals on the removal rate of ammonium.The saturated ammonium adsorption capacity of expanded vermiculite was found to be 17.32 mg·g-1,and the removal rate of NH4-H is over 65% within pH4.0～7.0.If the NH4-H density is increasing from 200 mg·L-1,the removal rate of NH4-N will be rising.The basic data and theoretical discussion from the present study support the use of expanded vermiculite as a new medium for removal of nitrogen in wastewater treatment. |
