给水处理工艺技术文献综述
[摘要]给水处理的主要任务和目的就是通过一定的处理方法去除水中的杂质，从而得到优良和安全的水供人们使用。到20世纪初，饮用水净化技术已经基本形成了现在被人们普遍称之为常规处理工艺的处理方法，即混凝、沉淀、过滤和消毒。这中工艺成为了目前饮用水的主要工艺。本文简要交代了目前给水面临的问题，水处理工艺的情况以及高效的热门的水处理技术。

Literature review on treatment technology of water supply
Abstract: The main task and purpose of water treatment is to remove impurities in water by certain treatment methods, so as to obtain good and safe water for people to use. By the beginning of the 20th century, drinking water purification technology has basically formed what is now commonly known as the conventional treatment process, namely coagulation, precipitation, filtration and disinfection. This process has become the main process of drinking water. This paper briefly describes the current problems faced by water supply, water treatment process and efficient hot water treatment technology.

饮用水常规工艺的主要目标是去除水源水中的悬浮物、胶体杂质和细菌。混凝是向原水中投加混凝剂，使水中难以自然沉淀分病的悬浮物和胶体颗粒互相聚合形成大颗粒的絮体。沉淀是将混凝后形成的大颗粒絮体通过重力分离。过滤则是利用颗粒状滤科载留经沉淀后出水中残留的颗粒物，进一步去除水中杂质，降低水中的混浊度。过滤之后采用消毒方法来灭活水中致病微生物，从而保证饮用水的卫生安全性。
