摘要

勃兰登堡州是德国缺水和干旱现象日益严重的地区，中水回用可以抵消饮用水供应、农业灌溉和工业用水之间的竞争。在勃兰登堡州，集中式和分散式再生水源可分别替代 245% 或 28% 的农业灌溉用水。针对这种再利用方案，研究了有机微污染物的去向，包括二苯甲酸酯 (DZA) 和卡马西平 (CBZ)。通过溶液计研究和温室盆栽实验，分析了有机微污染物在当地沙质土壤中的滞留以及向芝麻菜根部和叶片的转移情况。研究发现，DZA 可垂直迁移，并在芝麻菜根部或根部积累，根部浓度系数为 1,925 ± 34%，但由于分子的固有特性，生物浓缩系数较低。CBZ在沙质土壤中不具流动性，但在芝麻菜根部和叶片中的累积系数分别为 70 ± 7% 和 155 ± 12%。强烈建议进一步研究植物对更多物质的潜在吸收和地下水富集，并在中水回用前对废水进行三级处理。

Potential and risks of water reuse in Brandenburg (Germany) – an interdisciplinary case study

For Brandenburg, a region in Germany with increasing water shortage and drought events, water reuse can counteract competition scenarios between drinking water supply, agricultural irrigation, and industrial use. Centralized and decentralized sources for reclaimed water are found to potentially substitute 245 or 28% of irrigation water, respectively, in agriculture production in Brandenburg. For such a reuse scenario, the fate of organic micro-pollutants is examined for diatrizoate (DZA) and carbamazepine (CBZ). Retention in local sandy soil and transfer into roots and leaves of arugula are analyzed in lysimeter studies and greenhouse pot experiments. Vertical transport was found for DZA and accumulation in or on arugula roots with a root concentration factor of 1,925 ± 34% but a low bioconcentration factor due to intrinsic molecule properties. CBZ was not found to be mobile in the sandy soil but accumulates in arugula roots and leaves by factors of 70 ± 7% and 155 ± 12%, respectively. Further research on potential plant uptake and groundwater enrichment for more substances is highly recommended as well as tertiary wastewater treatment prior to water reuse.
