近十年来,我国给水事业取得极大进展,供水量不断增加,新建和扩建了大量水厂。节能作为评价给水系统工程效益好坏的标准之一,就显得特别的重要,现就水厂及管网设计运行中节能降耗问题谈几点看法,以供参考。一选择合理的供水系统在进行给水工程的规划设计中,就应注意节能问题。 1 在条件适宜时应采用分质、分压或分区供水系统。 2 对于用水量较大的用户,宜采用循环供水系统。 3 在条件允许时应尽可能使水厂位于用户的中心位置。 In the past ten years, great progress has been made in the water supply industry in our country, water supply has been constantly increasing, and a large number of water plants have been newly built and expanded. As one of the criteria to evaluate the efficiency of water supply system engineering, energy conservation is of particular importance. Here are some opinions on saving energy and reducing consumption in the design and operation of waterworks and pipe networks for reference. A reasonable choice of water supply system in the planning and design of water supply projects, we should pay attention to energy-saving issues. 1 When conditions are appropriate, the use of sub-quality, partial pressure or district water supply system. 2 for larger users, should adopt a circular water supply system. 3 Where possible, the water plant should be located in the center of the user as far as possible.
