Abstract: To improve the lead-absorption capacity of natural zeolite，a study on activation method，including soaked in inorganic acid，alkali and salt，have been carried out.Results showed that by activation treatment，natural zeolite can strongly absorb Pb↑2+ in waste water.Especially，the zeolite activated with 2 mol/L sodium chloride had the best effect of removing lead from water and its absorbent capacity was increased by 89.96% than that of natural zeolite.The static experiment results showed that the optimum static absorption time was 120 min； raw water pH should be controlled at 5.0 to 6.0，and the absorption process conformed to Freundlich isothermal line q<SUB>e</SUB>=25.08 ρ<SUB>e</SUB><SUP>0.319 3</SUP>.The dynamic results showed that the adsorption rate of activated zeolite to Pb↑2+ was greater than that of activated carbon and when the concentration of Pb↑2+ in waste water was 213.64 mg/L，maintaining velocity of flow from 2.36~2.82 mL/s，and the breakthrough capacity was 55.62 mg/g，the treatment capacity of the former was 1.44 times larger than that of the latter.
