摘要:

矿产资源生产过程中产生大量酸性矿山废水,其酸性强、硫酸盐含量高,且重金属离子种类多,易造成环境污染。试验采用生物炭吸附—沉淀法去除酸性矿山废水中重金属离子,生物炭以玉米秸秆为原料,在600 ℃下热解制?桑疾炝似涠运嵝钥笊椒纤型コ挠跋欤约吧锾课郊镣迅皆偕蟮奈侥芰Γ恢蟛捎贸恋矸ㄈコ渌亟鹗簦砗蠓纤懈魑廴疚锎锏GB 8978—1996 《污水综合排放标准》一级排放标准要求。

Abstract:

The production process of mineral resources generates a large amount of acid mine drainage,which is highly acidic,has a high sulfate content,and contains multiple heavy metal ions,easily leading to environmental pollution.In this experiment,biochar adsorption-precipitation method was used to remove heavy metal ions from acid mine drainage.The biochar was produced from corn stalk through pyrolysis at 600 ℃.The study investigated its effect on copper removal from acid mine drainage and the adsorption capacity of the regenerated biochar adsorbent.Subsequently,the precipitation method was used to remove other heavy metals,and the treated wastewater met the Class I discharge standard requirements of GB 8978-1996 Comprehensive Wastewater Discharge Standard.
