中文摘要:

利用天然沸石和泥炭作为原材料,水泥既作为粘结剂又作为原材料,同时添加一定量的外加剂,研制了一种具有一定抗压和抗拉强度并同时具有脱氮除磷功能的新型环保合成材料。实验结果表明,天然沸石:泥炭质量比为7:1,合成材料的耐水性能良好,其抗压强度高于混凝土实心砖等级标准中的最低等级MU15,抗拉强度高于混凝土结构设计规范标准中的最低等级C15,对氨氮和总磷的去除效果良好,遵循Langmuir和Freundlich吸附等温模型及准二级动力学模型。

英文摘要:

The article investigated a new environment-friendly synthetic material which is made of natural zeolite,peat,cement and additive.Here natural zeolite,peat and cement are raw material,and the cement is also used as inorganic gelatinization.The synthetic material with good compression strength and tensile strength is effective in removing ammonium nitrogen and phosphorus.The experiment result showed that with a mass ratio for natural zeolite and peat is 7:1,the material achieves a compressive strength higher ...
