消毒技术在自来水厂的应用探析

摘要:自来水厂的水是人们饮用水的直接来源,因此,自来水厂的水的安全性是保障人们生命健康安全的重要基础。如何采用有效的消毒技术对自来水进行消毒是水处理中保证水质的首要前提。本文介绍了国内的自来水厂常用的几种消毒技术,主要有液氯消毒、次氯酸钠消毒、臭氧消毒、紫外线消毒等等,并详细分析比较每种技术的优劣。希望各项消毒技术能在应用过程中不断完善,从而在应用中更有效的发挥消毒效果,保证饮用水质。

Analysis on the application of disinfection technology in waterworks

Abstract:The water from the waterworks is the direct source of drinking water for people. Therefore, the safety of the water from the waterworks is an important basis for ensuring people's life, health and safety. How to use effective disinfection technology to disinfect tap water is the primary premise to ensure water quality in water treatment. This paper introduces several disinfection techniques commonly used in domestic waterworks, including liquid chlorine disinfection, sodium hypochlorite disinfection, ozone disinfection, ultraviolet disinfection, etc., and analyzes and compares the advantages and disadvantages of each technique in detail. It is hoped that the disinfection technology can be improved continuously in the application process, so as to play the disinfection effect more effectively in the application and ensure the drinking water quality.

Key words:Water works; Disinfection technology; Water treatment

1.前言

水是生命之源 ,是人类赖以生存的基本物质。俗话说:人能三日无粮,不可一日缺水这形象地说明了水的重要作用。水是如此重要的,但是通过一些医学专家的研究,水同样是很多疾病的传播介质。据世卫组织统计,目前全球超过 80%的疾病是通过不干净的饮用水传播出来的。水质决定着人的体质,于是自来水的消毒处理是保证我们人类合格用水的关键一步。当前我国的大部分自来水厂采用的消毒方法是通过氯化法进行消毒处理的,但是通过这种方法处理的自来水会产生一些卤化有机物,而这些卤化有机物中很多是致癌物或诱变剂,常规处理工艺对氯化法产生的副产物不能有效地进行去除。
