摘　　要：为研究火山灰陶瓷滤料对煤层气采出水中铁、锰的去除效果,采用模拟配水分析了pH值、滤料厚度、滤速和运行时间对处理效果的影响,采用原水分析了反冲洗效果。结果表明:最佳pH为8,铁、锰去除率分别达到98.8%和98.4%;铁锰去除率与滤料厚度呈正相关关系,40 cm和60 cm厚度的滤料对铁锰的去除率较为接近,分别为97.1%~97.5%和98.4%~98.8%;铁锰去除率与滤速呈负相关关系,滤速为1 m/h和2 m/h两种情况下的去除效果较为相近;原水实验在进行12 h后,稳定性降低,铁锰的去除率分别降低至95.7%和80.4%。In order to explore the effect of pozzolan ceramic filter on the removal of iron and manganese in coal-bed methane produced water,the influences of pH,filter thickness,filtration rate and running time on the treatment effect was analyzed with simulated water.The effect of backwash was explored with raw water.The results show that the optimum pH is 8,and the removal rates of Fe and Mn are 98.8%and 98.4%,respectively.The removal rates of iron and manganese are positively correlated with the thickness of the filter material.The removal rates of iron and manganese for 40 cm and 60 cm thickness filters are relatively close,97.1%~97.5%and 98.4%~98.8%,respectively.The removal rates of iron and manganese are negatively correlated with the filtration rate,and the removal rates are similar when the filtration rates are 1 m/h and 2 m/h.For the raw water experiment,after operation for 12 h,the stability decreases,and the removal rates of iron and manganese decrease to 95.7%and 80.4%,respectively.
