水源在输送过程中有关问题的研究

Study on the problems caused by the water transportation

从水厂出来的水源各项标准均已达标,水源在输送至用户的过程中,需要经过各种材质的管道及设备,由于管道本身及设备的老化、污染、放射性、损坏等问题,再加上施工不规范,便造成到户水质污染。本文主要从管道的材质及设备上着手,说明了早期管材的一些弊端,并论述了目前市场上适用的各种新型管材的特性。无论旧管道改造,还是新管道铺设,通过重视管道材质选择、设备及管材防腐处理、规范施工及运行维护等方面,一定会改善输送过程造成的水质污染问题。

The water which comes from waterworks is fit for the water criterion. The water is transported to the user by many pipes and equipments. Because the pipes and equipments will be aging, polluted, radioactive, ruined and nonstandard constructed, the water is always polluted. This paper mainly analyses the material of the pipes and equipments and shows the fault of the pipes and equipments which used before. The paper also dilates on the property of the new pipes and equipments used recently. On the change and building of pipes＇ engineering, the water pollution can be solved by attaching importance to choose the pipes, antisepticising the pipes and equipments, constructing standardized, running maintenance.
