【摘要】 武汉市余氏墩水厂和走马岭水厂都属于武汉市东西湖自来水公司,但两水厂制水工艺有不同之处。通过分析两水厂1年的出厂水浊度、氨氮、COD_Mn及去除率,对比了两水厂运行能耗、原水水质及工艺区别,分析了不同原水水质及制水工艺对出厂水水质的影响。结果表明,原水水质对工艺处理效果有较大影响。余氏墩水厂出厂水浊度为0. 18 NTU,去除率为99. 07%;氨氮浓度<0. 03 mg/L,去除率为76. 54%; COD_Mn为1. 90 mg/L,去除率为31. 88%。走马岭水厂出厂水浊度为0. 16 NTU,去除率为98. 41%;氨氮浓度<0. 02 mg/L,去除率为74. 71%; COD_Mn为1. 64 mg/L,去除率为32. 80%。由于走马岭水厂自动化程度更高,其运行能耗较低。余氏墩水厂和走马岭水厂耗矾量年平均值分别为26. 38、9. 74 kg/10³m³,耗氯量年平均值分别为3. 25、2. 69 kg/10³m³。更多还原

【Abstract】 Wuhan Yushidun Waterworks and Zoumaling Waterworks belong to Wuhan Dongxihu Water Supply Company. The water treatment processes of the two waterworks are different. Through the analyses of turbidity,ammonia nitrogen,and COD_Mnof the finished water and their removal rates of the two waterworks for one year,the operation energy consumption,the raw water quality,and the water treatment process of the two waterworks were compared,and the influence of raw water quality and water treatment process on the finished water quality was studied. The results showed that the raw water quality had large impact on the treatment efficiency. The finished water quality of Yushidun Waterworks were as follows: turbidity was 0. 18 NTU,removal rate was 99. 07%; ammonia nitrogen was less than 0. 03 mg/L,removal rate was 76. 54%; COD_Mnwas 1. 90 mg/L,removal rate was 31. 88%. The finished water quality of Zoumaling Waterworks were as follows: turbidity was 0. 16 NTU,removal rate was 98. 41%;ammonia nitrogen was less than 0. 02 mg/L,removal rate was 74. 71%; COD_Mnwas 1. 64 mg/L,removal rate was 32. 80%. Zoumaling Waterworks showed lower operation energy consumption due to higher level of automation. The annual average dosage of alum at Yushidun Waterworks and Zoumaling Waterworks were 26. 38 kg/10³ m³ and 9. 74 kg/10³ m³,respectively; the annual average dosage of chlorine was3. 25 kg/10³ m³ and 2. 69 kg/10³ m³,respectively.更多还原
