- 摘要:
- 嘉兴市地处杭嘉湖平原,饮用水水源为地表河网水,历史上受到严重的污染。回顾了近40年来,随着水源水质的变化和饮用水标准的不断提高,嘉兴饮用水处理技术的应对措施和发展历程,总结了从常规处理工艺到生物预处理工艺、深度处理工艺以及水源湿地技术的发展必要性和特点,尤其是根据科学原理,以工程技术措施系统解决冬季低温期除氨氮的难题,为饮用水厂的建设和发展提供了一个技术思路。
- Abstract:
- Jiaxing City is located in the Hangjiahu Plain. The source of drinking water is the surface river network water, which has suffered severe pollution in history.This paper reviews the solutions and development of drinking water treatment technology in Jiaxing City in the past 40 years with the changes in water quality and continuous improvement of drinking water standards, and summarizes the development necessity and characteristics from the conventional treatment technology to biological pretreatment technology, advanced treatment technology and water source wetland treatment technology. In particular, according to scientific principles, engineering and technical measures have been used to systematically solve the difficulty of removing ammonia nitrogen in the low temperature period in winter, which could provide a technical method for the construction and development of drinking water plants.
