硅碳素处理含锰地下水的试验研究

对硅碳素（ANJ．SIC）和锰砂去除锰的效果进行试验研究。试验表明：ANJ．SIC有较好的除锰效果，当原水含锰量为2．06～2．34mg／L，流速范围在5．2—16．11m／h变化时，去除率在100％～94％，相同情况下锰砂的去除率在43％～32％。流速发生变化时，ANJ．SIC维持的出水达标时间发生变化，流速越大，ANJ．SIC达到吸附饱和的时间越短。ANJ．SIC各层对锰的去除率随时间变化单调下降，并呈下降减缓的趋势。去除率没有集中在某一部分的现象，各层均有一定的去除能力。

Study on the resistance of ANJ. SIC removal manganese which in the groundwater

The study of effects on removal manganese which in the groundwater by ANJ.SIC and manganese sand was carried out.Tests showed that ANJ.SIC have better results in removaling manganese which in the groundwater,when the raw water concentration range 2.06mg/L-2.34mg/L,velocity range 5.2m/h-16.11m/h changes,the removal rate of between 100%-94%,the same circumstances of the removal of manganese sand in between 43%-32%.Changes in velocity,ANJ.SIC maintainS the standards of the time change in water flow rate the greater the ANJ.SIC saturated absorption,the shorter the time.ANJ.SIC at all levels of the manganese removal rate monotonic decline over time,and the trend of slow decline.Removal rate of removal is not concentrated in a certain part of the phenomenon,at all levels have the ability to remove certain.
