摘要:

以钼酸铵为改性剂,对天然膨润土进行无机改性,制得钼酸铵无机改性土用于屠宰废水的处理。实验结果表明:在投加膨润土质量浓度为15g/L、pH=5、搅拌时间为10min、离心时间10min的条件下,COD去除率可达90%,达到了预期目标。

关键词: 钼酸铵, 膨润土, 屠宰废水

Abstract:

Ammonium molybdate inorganic modified bentonite has been prepared by using ammonium molybdate as modifying agent, modifying natural bentonite. It is used for treating slaughtering wastewater. The optimized conditions for wastewater treatment are as follows:the dosage of ammonium molybdate modified bentonite is 15 g/L, pH is 5, stirring time and centrifugation time are 10 min respectively. Its maximal removal efficiency of COD is 90%, reaching the predicted target.

Key words: ammonium molybdate, bentonite, slaughtering wastewater
