xurl}3uor)yOngshuI循环用水 (circulaling water·use) 由一个工厂、车间或工段的给水、排水系统组成一个闭路循环的用水系统,将系统内产生的废水。经适当处理后重复使用,不补充或少量补充新鲜水,而不排放或少排放废水的用水方式。工业冷却用水在冷却生产设备和产品过程中,水温升高,其化学性质变化不大,但冷却水降温后长期循环使用,水中某些溶质浓缩,尘土积累,微生物滋长,可以造成设备管道内垢物沉积或对金属设备管道北京印染厂的净水站腐蚀,因此必须对其进行水质稳定处理,才能使循环用水系统正常运行。循环用水系统一般由以下几部分组成:①生产过程中的热交换器;②冷却塔或冷却池;③循环水泵及集水池。在水资源日趋紧缺的情况下,用循环冷却水系统代替直流冷却水(一次用水)系统,逐步实现闭路循环冷却用水,不断提高水的重复利用率是今后工业发展的趋势。工业废水的循环利用,水质的处理比较复杂,需要用特殊的处理工艺,处理回用成本较高,不如冷却用水循环利用普及。(陈志恺)
