| 中文摘要 |
| 针对姚江水源受污染的现状和原传统净水工艺去除污染效率低、药耗大等缺点,对宁波市梅林水厂的传统净水工艺进行了改进,并对改进前后的去除污染效率进行了对比试验研究。结果表明,在姚江水质为pH6.5-7.6、浊度7-20NTU、色度25-37度、NH4+-N0.25-9.0mg/L、NO2--N0.025-0.25mg/L、CODMn6-18.9mg/L的条件下,改进后的生化工艺系统对浊度、色度、NH4+-N、NO2--N及CODMn的平均去除率比传统工艺分别提高了24.5%、30.0%、58.5%、70.0%和27.5%,除污染效果明显优于传统净水工艺;并且可节约矾耗50%以上和氯耗77%左右。 |

| The parellel tests to remove the pollutants by improving the conventional drinking water purification process have been conducted at Meiling water plant,Ning Bo City,because of pollution of water resource in Yao River and the conventional process with a low removal efficiency of pullutants and a high coagulant and chlorine demand.The results show the improved biochemistry process for drinking water can reach an average increase of 24.5%、30.0%、58.5%、70.0% and 27.5% respectively for the removal efficiency of turbidity、colorization、NH4+-N、NO2--N and CODMn under the condition of pH6.5-7.6、turbidity 7-20mg/L、colorization 25-37 degree、NH4+-N 0.25-9.0mg/L、NO2--N 0.025-0.25mg/L and CODMn 6-18.9mg/L for raw water in Yao River.It is better than the conventional process in removing the pollutants and can also save coagulants of above 50% and chlorine of about 77%. |
