摘　　要：通过改变吸附剂量和制革废水浓度,考察了粉煤灰、鹅卵石和砂土这三种基质对制革废水的处理效果。结果表明:随着吸附剂量的增加,制革废水的出水浓度逐渐减小。比较四种浓度梯度下三种基质对制革废水的处理效果,得出基质更适于处理低浓度废水。对制革废水的处理效果:粉煤灰>鹅卵石>砂土。The treatment efficiency of leather wastewater with fly ash,cobble and sand was studied through changing adsorption capacity and tanning wastewater concentration to the COD,NH4＋-N,Chloride,Cr6＋ and total chromium contents in tanning waste water.Results showed that,with the increase of adsorption dose,the effluent concentration of tanning wastewater decreased gradually.The substrate was more suitable for low tanning wastewater concentration,comparing with the treating efficiency of four tanning wastewater concentrations.The treating efficiency of tanning wastewater was fly ashcobblesand.
