| 摘 要： | 通过土壤柱实验,研究了土壤含水层处理工艺对污水处理厂二级处理出水的处理效果。初步讨论了土壤含水层处理工艺对各种污染物的去除机理,并评价了不同回用途径再生水对人体的健康风险。研究结果表明:土壤含水层处理工艺能够有效去除二级处理出水中的有机物和重金属离子,对大肠菌和粪大肠菌的去除率大于99.9%。健康风险评价结果显示:再生水的健康风险主要来自致癌物质,终生致癌风险在10-6数量级,而非致癌物质的健康危害风险在10-9数量级。 |

| Abstract: | Effect of soil aquifer treatment (SAT)on the secondary treatment effluent was investigated using soil-column experiments. Removal mechanism for various pollutants were primarily examined,and public health risks of reclaimed wastewater was assessed. Results showed that organic matter and heavy metal can be effectively removed from the secondary effluent,with removal efficiency of both total and fecal coliform more than 99.9%. The health risk assessment indicated that the health risk of reclaimed wastewater by SAT came from carcinogenic risk which was in negative six orders of magnitude while for chemicals in negative ten orders of magnitude. |
| Keywords: | artificial groundwater recharge soil aquifer treatment effluent from secondary treatment regeneration health risk assessment |
