| 摘 要： | 通过静态试验,分别研究了氧化时间、水温、氧化剂投加量等因素对次氯酸钠预氧化效果的影响。试验结果表明,在原水水质pH值为7.8～8.2,浊度为6.0～18.0NTU,CODMn的质量浓度为4.2～6.7mg/L,UV254值为0.094～0.141,水温为6.0～15.0℃时,次氯酸钠投加量12.5mg/L,经20min氧化后,CODMn去除率达到25%左右,再经过混凝沉淀后,CODMn去除率达60%左右。

| Abstract: | The effects of oxidation time,water temperature,dosage of oxidant and some other factors on the results of the sodium hypochlorite pre-oxidation were studied respectively through the static test.The results of the test show that,under the condition that the pH value of the raw water is 7.8-8.2,the turbidity is 6.0-18.0 NTU,the mass concentration of CODMn is 4.2-6.7 mg/L,the value of UV254 is 0.094-0.141,the water temperature is 6.0-15.0 ℃,12.5 mg/L of sodium hypochlorite is added,the removal rate of CODMn reaches about 25% after 20 min of oxidation,and then through the coagulation-sedimentation,the removal rate of CODMn reaches about 60%. |
