农村供水中消毒副产物的形成与调控技术探讨

Discussion on the Formation and Regulation Technologies of Disinfection By-products in Rural Water Supply

摘要:

由于农村地区通常采用较简单的供水和处理技术,因此解决消毒过程中形成的消毒副产物(Disinfection By- products, DBPs)问题尤为重要。消毒副产物是在使用氯或其他消毒剂处理水时,消毒剂与水中的自然有机物和无机物反应而形成的化合物。这些副产物包括但不限于三氯甲烷、卤代乙酸等,长期接触这些物质对人体健康造成不良影响。为了有效去除或减少DBPs,文章评价了包括物理、化学及生物技术在内的多种处理方法。通过合理选择和组合不同的水处理技术,可以有效减轻DBPs的影响。未来的研究需进一步探索低成本且适合农村地区的DBPs控制策略,以提高农村居民的饮用水质量和安全。

Abstract:

Since relatively simple water supply and treatment technologies are usually adopted in rural areas, it is particularly important to solve the problem of Disinfection Byproducts (DBPs) formed during the disinfection process. Disinfection byproducts are compounds formed by the reaction of disinfectants with natural organic and inorganic substances in water when chlorine or other disinfectants are used to treat water. These byproducts include but are not limited to chloroform, haloacetic acids, etc. Long- term exposure to these substances will have adverse effects on human health. In order to effectively remove or reduce DBPs, this paper evaluates a variety of treatment methods including physical, chemical and biological technologies. The impact of DBPs can be effectively mitigated by reasonably selecting and combining different water treatment technologies. Future research needs to further explore low- cost DBPs control strategies suitable for rural areas to improve the quality and safety of drinking water for rural residents.
