【摘要】 通过实验分析了粉煤灰、空心砖屑、煤渣和活性炭四种填料对生活污水中污染物(COD、NH3-N、TP)的吸附能力与吸附类型。实验结果显示:空心砖屑对氨氮和总磷的吸附容量明显大于其它几种填料,且四种填料的吸附容量都是随着吸附剂量的增大而增大;活性炭对COD的吸附容量稍大于其它几种填料,吸附剂量对各填料吸附COD效果的影响存在差异。同时,实验发现四种填料对COD、NH3-N、TP的吸附均符合Freundich规律。更多还原

【Abstract】 This paper analyzes media’s absorbing capability for domestic wastewater pollutant(COD、NH3-N、TP)and its absorbing type by doing experiments with fly ash,hollow brick crumbs,coal cinder and active carbon etc.four media.The results showed that for NH3-N and TP,the absorbing capacity of hollow brick crumbs was obviously better than these of the other three.Their absorbing capacity was all enhanced as the absorbing dosage increased.For COD,the absorbing capacity of active carbon was a little better than others.Absorbing dosage affected each media to a certain extent,and all the adsorption of the four medias towards COD?NH3-N and TP follows the Freundich rule.更多还原
