【摘要】 选用河沙为滤料,研究了直接过滤法处理低浓度含Pb2+废水的条件。实验表明,滤料粒径0.5~0.7 mm,滤层厚度0.8 m,滤速8~11 m/h,pH控制在9.0~9.5范围内,可有效去除废水中的Pb2+离子。更多还原

【Abstract】 The condition of treating leaded wastewater was dicussed by using of directly-filtration（method.）The results showed that Pb²⁺ was removed effectirly when the grit used as filter with the diameber beteveen 0.5 mm and 0.7 mm,the height about 0.8 m,the fitering speed between 8 m/h and 11m/h at the pH between 9.0 and 9.5.更多还原
