| 摘 要： | 以洞庭湖区地下水为水源,通过调节试验原水的pH值,考察不同pH值条件下铁锰去除效果的变化,试验结果表明：随着pH值的升高,铁的去除从最初没有效果（pH值小于6.5）到接触氧化除铁（pH值在6.5～7.5）,再过渡到空气氧化除铁法（pH值大于7.5）;锰的去除在pH值大于5.0时为生物除锰法,在pH值小于5.0时生物除锰丧失了除锰能力.

| Abstract: | With groundwater in Dongting Lake zone as source water,the variety of the effect of iron and manganese removal in different pH range was investigated by adjusting pH values of the experimental raw water.The results of the test show that,there is no effect on iron removal when pH value below 6.5,with the rising of the pH value,the method for the removal of iron is altered from contacting-oxidation(6.5 < pH < 7.5) to air-oxidation(pH > 7.5).And the method for the removal of manganese is micro-oxidation while the pH value is higher than 5.0,on the contrary,when the pH value is less than 5.0,the manganese-removing ability of micro-oxidation method is lost. |
