博乐市农村饮用水工程净化处理工艺应用

Application about Purification Technology in Rural Drinking Water Project in Bole City

为解决新疆博乐农村地区水资源紧张、饮用水安全难以保障等问题,文章在饮用水水源特点及常规处理工艺的基础上,提出了由沉淀、粗滤、慢滤、消毒等多个净化工艺组成的慢滤工艺,并确定了各净化工艺设计技术参数,分析了慢滤工艺净化处理前后水源中有机物氨氮、重金属铜和铁含量变化关系,得到慢滤技术净化处理水源时,有机物氨氮、重金属铜和铁的净化率分别为83.4%、 85.9和89.5%;慢滤工艺技术简单,造价成本低,修建规模可以依据需要供水人数进行确定,净化处理后水源达到《生活饮用水卫生标准》要求。研究结果为慢滤工艺在新疆博乐农村地区推广使用提供理论依据。

In order to solve the problems about shortage of water resources and difficulty in safe drinking water in Bole rural areas in Xinjiang,in this paper,the author,based on the analysis on the characteristics of drinking water sources and their traditional treatment processes,put forward slowly filtrating process being composed of sedimentation,coarse filtration,slow filtration,disinfection and so on purification processes,determined the design technical parameters relative to each purification process,analyzed the relationships among the content of organic ammonia nitrogen,heavy metal copper and iron in the water source before and after purification and treatment by slowly filtrating process,and obtained under the condition of slowly filtrating process being used,the purification rates of organic ammonia nitrogen,heavy metal copper and iron are respectively 83.4%,85.9%and 89.5%.The new process is simple in technology,low in cost,and the construction scale can be determined based on the number of water users.After purification,the water quality of the source can be met the requirement in relevant "Health Standard of drinking water in Life".
