【摘要】 探讨了以改性天然磷灰石为原料制备颗粒状重金属废水处理剂的造粒方法和影响因素,结果表明:按-100目占75%的改性磷灰石配加6%A l和0.2%N-1,水分10%,造球12min,烘干后700℃焙烧20min制得的颗粒化水处理剂的抗压强度为18.14kg/cm2、比表面积为3.25m2/g、去除Pb2+能力为112.28mg/g。
【英文摘要】 The pelleting methods for preparing granular adsorbent for heavy metals by using modified natural apatite as raw material were explored.The factors influencing removal results of heavy metals were also researched.The test results indicated that the new wastewater treatment agent possesses 18.14kg/cm2 compression strength,3.25m2/g specific surface and removal efficiency of 112.28mg/g Pb2+ under the following optimal conditions:the fraction of-100mesh of the modified natural apatite accounts 75%,clay A1 is 6%...
