摘要
水利地基施工过程中不可避免地会造成地下水污染,为保证地下水环境健康,进行生态修复处理可以对地下水污染起到控制作用,为此提出水利地基施工地下水污染生态修复处理工艺。以某处水利工程地基修建地区为例,设置16个采样点,采集地下水样本。设计生态混凝土层、铁粉+活性炭+人造沸石层和植物分解层等三层生态修复处理工艺,针对地下水样本开展多层净化处理。实验结果表明:经过三层工艺处理后,污水的总磷、总氮、氨氮、悬浮物的含量明显降低,去除率均达到了80%~90%以上,证明了所研究水污染处理工艺的有效性。
Groundwater pollution was inevitable during the construction of water conservancy foundations.In order to ensure the health of the groundwater environment,ecological remediation treatment could play a control role in groundwater pollution.Therefore,the ecological remediation treatment process for groundwater pollution during water conservancy foundation construction has been proposed.Taking a water conservancy project foundation construction area as an example,16 sampling points were set up and groundwater samples were collected.Three layers of ecological remediation treatment processes,including ecological concrete layer,iron powder+activated carbon+artificial zeolite layer,and plant decomposition layer,were designed,and groundwater samples were subjected to multi-layer purification treatment.The experimental results show that after the three-layer process treatment,the content of total phosphorus,total nitrogen,ammonia nitrogen,and suspended solids in the sewage was significantly reduced.The removal rate reaches 80%to 90%,which proves the effectiveness of the water pollution treatment process studied.
