通过堆肥吸附水体中重金属铜和锌的试验，探究吸附时间、水体pH值、堆肥添加量、振荡速率、重金属离子浓度等对水体中重金属铜和锌去除率的影响。结果表明：堆肥在添加量为8~10 g/L，重金属离子初始浓度为100~200 mg/L、pH值在3~4的条件下吸附量最大，而振荡速率的影响不大；水体中铜和锌的吸附动力学方程符合准二级动力学方程，以化学吸附为主。

Through conducting experiment on adsorptio of Cu2+ and Zn2+ in waterbody by compost, the inlfuences of adsorption time, pH value of waterbody, adding amount of compost, stroke speed, and concentration of heavy-metal ions on removal rate of Cu2+ and Zn2+ in waterbody were evaluated. The results showed that compost had the largest adsorption amount when adding amount, initial concentration of heavy-metal ions and pH value were 8~10 g/L, 100~200 mg/L and 3~4, respectively, and the stroke speed had little inlfuence on it; the adsorption kinetic equation of Cu2+ and Zn2+ in waterbody could be descr...
