【摘要】 用天然状态的硫铁矿处理模拟含Pb2+废水,探讨了废水酸度、吸附时间及废水中的Pb2+初始浓度对Pb2+吸附效果的影响,发现利用硫铁矿吸附处理含铅废水具有吸附量大、处理效果好的优点,经处理后的含Pb2+废水已达国家排放标准(Pb2+<1.0mg/L),并对其实验机理进行了初步探讨.更多还原

【Abstract】 The wastewater treatment of removing lead by pyrites adsorption was studied.The influences of acidity,adsorption time and initial concentration of lead in wastewater on the adsorption of Lead were studied.The advantages of this method were large adsorptive capacity.The wastewater after treated achieves the national discharge standard.The mechanism of the treatment was discussed.更多还原
