采用一套生物试验（水蚤急性毒性、遗传毒性、雌激素和抗雌激素毒性）评价再生水回用于实验室规模的人工地下水回灌系统的安全性。采用1 mg O3·（mg DOC）− 1的臭氧氧化预处理，对4种有毒物质均有较好的去除效果，去除率在56%~ 99%之间。在渗流层中，负责毒性的化合物被有效地去除比散装有机化合物。然而，它们在饱和含水层处理过程中优先被去除，每碳质量的所有毒性效应下降了20- 50%。因此，建议在水回用前在含水层中旅行一个月以上。由于UV 254与毒性数据显著相关，因此可以作为毒性的指标。通过生物安全性评价，土壤含水层处理与臭氧氧化相结合，可提供毒性不高于常规天然饮用水源的新水源。
A set of bioassays (acute toxicity to Daphnia, genotoxicity, estrogenic and antiestrogenic toxicity) was used to evaluate the safety of reclaimed water reuse in a lab-scale artificial groundwater recharge system. Ozonation of 1mg O3·(mg DOC)−1was used as the pretreatment and was proved to be effective in removing the four toxicity, with removal ratios ranging from 56% to 99%. In the vadose layer, the responsible compounds for toxicity were less efficiently removed than the bulk organic compounds. However, they were preferentially removed during the saturated aquifer treatment, with all the toxic effects per carbon mass dropping by 20–50%. Therefore, more than one month traveling in the aquifer is suggested before water reuse. Since UV254was significantly correlated with the toxicity data, it could serve as an indicator of the toxicity. With the bioassay-based safety evaluation, the combination of soil aquifer treatment and ozonation could provide new water sources with no higher toxic than the conventional natural drinking water source.
