摘要
针对水中低浓度的锰离子不易去除的问题,研究并比较了纳米分子筛和两种硅藻土(CD02和CD010)在静态条件下的除锰性能.考察了吸附材料投加量、吸附时间、进水pH值对除锰效果的影响.结果表明:投加量分别为分子筛1.5 g/L、硅藻土2.0g/L,吸附时间30 min,进水pH值为7左右时,处理效果达到最佳,其中经过分子筛处理的水可以满足《生活饮用水水质卫生规范》的要求.并且对三种材料的静态吸附等温线进行了拟合.
Considering the difficulties on removal of low concentration manganese ion from water,the performance of manganese ion removal under static condition using adsorption materials like nano-molecular sieve and two kinds of diatomite(CD02 and CD010) was studied and compared.The effects of adsorbent amount,adsorption time and pH value of inlet water on removal performance were investigated.The results indicate that it can arrive to optimization treatment when putting nano-molecular sieve 1.5,g/L and diatomite 2....
