浊环水净化后用于净环补水的应用 柴艳红1 （鞍钢股份有限公司热轧带钢厂，鞍山 114021 ） 摘 要 钢铁企业轧钢系统浊环水是指在钢铁轧制过程中的冷却用落地水，除浊环系统原有水量，还包括净环及其 他系统用水后的落地水。排除浊环系统冷却蒸发掉的水，浊环系统的总体水量在系统的运行过程中是不断增加的， 这种运行方式将导致浊环系统吸水井溢流。同时，由于净环系统的蒸发和泄漏导致净环系统不断补充净化河水，如 果采用一种过滤方法将浊环水净化，作为净环补水的水源，这样既可以防止浊环溢流损失又可以满足净环补水的需 求。本系统的投入可以有效地解决这一问题，提高钢铁企业轧钢用水的利用效率，减少外排水量以及外排水对环境 的污染，在提高钢铁企业经济效益的同时增加了社会效益。 关键词 钢铁企业 浊环水 净化 净环水 The Application of the Purification of Sewage for New Water Chai Yanhong (Hot Strip Mill of Angang Co.,Ltd.，Anshan,114021) Abstract The sewage water of the steel rolling is the landing water which is used in the rolling process for cooling water. Apart from profiting by the supplying water of the sewage system , the system also includes the landing water of other systems. Although there is a part of water would evaporate, the recycling water is continuous increased which can make the absorbing well overflow. At the same time, by the evaporation and leakage of the new water system ,the clean-up river water has been added to the system continuously. If using a method to purify the sewage and turn it into the source of new water, it can prevent overflowing losses and environmental pollution and meet the needs of the new water. By using this system can solve the above mentioned problem effectively and raise the efficient use of the water, reduce the drainage and the environmental pollution ,improve the efficiency of the enterprises.
