摘要
阐述了自来水厂原水预处理和深度处理工艺改造的必要性,对可用技术方法的有效性、经济性及存在的问题进行了探讨。调研了两家分别采用常规处理技术、常规处理与深度处理相结合的自来水厂的典型年份春、夏两季的出水水质,发现在进水相同的情况下,经过工艺改造的水厂净水效果明显更优。提出了原水预处理采用“预氯化一粉末活性炭联用”、水厂深度处理采用“预臭氧一混凝、沉淀、过滤一后臭氧、活性炭一消毒”的改造方案建议。
The necessity of raw water pretreatment and advanced treatment process upgrades in waterworks is expounded,and the effectiveness,economical efficiency and existent issues of available technologies are discussed.Surveys on the effluent quality of two waterworks respectively using conventional treatment process and that combined with advanced treatment process were carried out in spring and summer of a typical year.It was found that under the condition of same influent,the water purification effect in the process-upgraded waterworks was evidently more superior.Suggestions have been given on the upgrading schemes of raw water pretreatment by using"a combination of pre-chlorination with powdered activated carbon"and advanced treatment by using"pre-ozonisation plus coagulation,sedimentation and filtration,plus post-ozonisation and activated carbon,and then disinfection".
