以葡萄糖及豆奶粉为碳氮源,采用不控制温度及pH的方式,在厌氧条件下探究不同m(COD)/m(SO42-)、HRT和进水Fe2+负荷对硫酸盐还原菌处理酸性矿山废水效果的影响。结果表明,在进水pH为3.0左右,水温为26～27℃,进水Fe2+的质量度低于450mg/L,m(COD)/m(SO42-)大于1.5的条件下,SO42-去除效果稳定,平均去除率在80%以上;而m(COD)/m(SO42-)大于2.0时,COD有较好的降解效果,Fe2+平均去除率在90%以上,重金属的平均去除率在99%以上。
Using glucose and soy milk as carbon and nitrogen sources, the effects of different m (COD) / m (SO42 -), HRT and influent Fe2 + loading on the acidity Effect of Mine Wastewater Effect. The results showed that under the conditions of influent pH of about 3.0, water temperature of 26 ~ 27 ℃, Fe2 + influx less than 450mg / L, and m (COD) / m (SO42-) greater than 1.5, SO42- removal efficiency And the average removal rate is more than 80%. When m (COD) / m (SO42-) is more than 2.0, COD has good degradation effect, the average removal rate of Fe2 + is above 90% and the average removal rate of heavy metals is above 99% the above.
