本發明有關一種以流體化床結晶技術合成鹼式氧化鎳結晶物之方法。此方法除了具有高效去除水中鎳離子之外，且可減少化學藥劑的使用。再者，該方法不需要在流體化床反應槽內使用異質擔體。調整水質條件包括pH、截面負荷、水力停留時間等，採用流體化床均質結晶系統回收鎳鹽的結晶顆粒以去除廢水中鎳離子。該方法所獲得的處理效率與結晶顆粒純度高，具有高的利用潛力。 The present invention relates to a method of synthesizing granular basic nickel oxide from nickel-contained wastewater by using fluidized-bed crystallization technology. In addition to a high efficiency of nickel ions removal from water, the method also can reduce the usage of chemical agents. Furthermore, this method has no need to apply heterogeneous carriers in the fluidized-bed reactor. By varying the operation conditions of pH, nickel surface loading and hydraulic retention time, nickel ions can be removed from wastewaters in a fluidized-bed homogeneous crystallization (FBHC) system by recovering crystallization of nickel salts. This method has a very high application potential because of high treatment efficiency and crystal purity.
