摘要： PROBLEM TO BE SOLVED: To provide an effluent treatment method used in a line for pickling a steel strip, which can pickle the steel strip in a solution having a constant acid concentration without increasing an effluent treatment load even when water is sprayed to front and rear sides of a squeeze roll so as to prevent the surface of the steel strip from being nonuniformly dried, and to provide an effluent treatment facility therefor.
SOLUTION: The effluent treatment method used in the line for pickling the steel strip comprises: sending sprayed water to an effluent treatment tank together with an acid removed by a squeeze roll, when water is sprayed onto the steel strip in either a front side or a rear side of the squeeze roll which is installed in an outlet of a pickling tank in the line for pickling the steel strip; and returning the acid removed by the squeeze roll to the pickling tank, when water is not sprayed in any of the front side and the rear side of the squeeze roll.

摘要翻译：要解决的问题：提供一种用于酸洗钢带的废水处理方法，其可以在具有恒定酸浓度的溶液中腌制钢带，而不增加流出物处理负荷，即使当喷洒水时挤压辊的前侧和后侧，以防止钢带的表面不均匀地干燥，并为其提供流出物处理设备。
解决方案：用于酸洗钢带的流水处理方法包括：将水喷射到前面的钢带上时，将喷射水与通过挤压辊除去的酸一起送到流出物处理槽中挤压辊的侧面或后侧，其安装在用于酸洗钢带的线中的酸洗槽的出口中; 并且当挤压辊的前侧和后侧中的任何一侧没有喷射水时，将由挤压辊除去的酸返回到酸洗槽。版权所有（C）2007，JPO＆INPIT
