Ltd., and proposed optimization methods for 环水母管，经原水池由升压泵增压，分别进入2 台反 systems of industrial backwater, water purification, make-up 应沉淀池进行混凝、澄清处理，单台反应沉淀池出力 water, refining treatment, and chemical water treatment. Through 为400 t/h 。出水一路进入工业水池，经工业泵送入全 equipment modification and system optimization, more than 100 厂工业水系统，另一路进入2 座空气擦洗滤池进行过 thousand tons of industrial water can be saved; the output of water in a mixed-bed cycle will increase to 45 thousand tons 滤，分别进入生活水池、消防水池和清水箱。 regarding the make-up water system, and 200 thousand tons 1.2.2 补给水处理系统 regarding the refining system. The paper also discussed the next 补给水系统由活性炭过滤器、一级除盐加混床组 study on the operation of high-speed mixed-bed ammonification 成，系统出力为2 120 t/h。一级除盐阳树脂型号为 and the implementation of oxygenation. 0017，阴树脂型号为213，混床阳树脂型号为D001-MB， KEYWORDS: supercritical unit; water treatment; system 阴树脂为D201-MB[1] 。炭床采用气、水反洗，一级除盐 optimization; all volatile treatment(AVT); combined water 采
