粒状腐植酸净水剂处理含铜废水的研究

Processing of Copper-bearing Wastewater with HumicAcid Type water Purifier

以重庆市南桐风化煤为原料制备粒状腐植酸净水剂，用静态实验法找出了处理含铜废水的适宜条件，再用动态实验法处理含Ｃｕ２＋１２４ｍｇ．Ｌ－１的镀铜漂洗水，当出水Ｃｕ２＋浓度低于国家排放标准即１．０ｍｇ．Ｌ－１时，工作吸附容量为３２．４ｍｇ．ｇ－１；饱和吸附容量为４５．８ｍｇ．ｇ－１，初步展示了一种处理含铜废水的新方法。

This thesis presents a new method of processing copper_bearing wastewater. The humic acid type water purifier, in form of particles, is manufactured from weathered coal of Nantong Mining Area in Chongqing. Through static test, the optimum condition on treating copper-bearing waste water has been found out. Then the washing water for copper plating, which contains Cu2+ 124 mg.L-1, is treated by dynamic test. When the concentration of Cu2+ in the outlet water is lower than the national standard for draining (1.0 mg.L-1), the working capacity of absorption is 32.4 mg.L-1 and the saturation capacity of absorption is 45.8 mg.L-1.
