The effectiveness of UV-based processes (UV and UV/H(2)O(2)) for the removal of pharmaceuticals in real wastewater using bench-scale experiment setup with a treatment capacity of 10 m(3)/day was investigated. Forty-one kinds of pharmaceuticals including 12 antibiotics and 10 analgesics were detected in secondary effluent used for tested water. For UV process a good removal seems to be expected for just a few pharmaceuticals such as ketoprofen, diclofenac and antipyrine. Especially, the removal efficiencies of macrolide antibiotics such as clarithromycin, erythromycin and azithromycin for UV alone process were found to be very low even by the introduction of considerable UV dose of 2768 mJ/cm(2). For UV/H(2)O(2) process, a 90% removal efficiency could be accomplished in 39 pharmaceuticals at UV dose of 923 mJ/cm(2), indicating that it will be possible to reduce UV energy required for the effective pharmaceuticals removal by the combination of H(2)O(2) with UV process.
采用处理能力为10立方米/天的实验室规模实验装置，研究了基于紫外线的工艺（紫外线和紫外线/过氧化氢）对实际废水中药物的去除效果。在用作测试水的二级出水中检测到41种药物，包括12种抗生素和10种镇痛药。对于紫外线工艺，仅对少数几种药物（如酮洛芬、双氯芬酸和安替比林）有望实现良好的去除效果。特别是，发现即使引入高达2768毫焦/平方厘米的紫外线剂量，单独的紫外线工艺对克拉霉素、红霉素和阿奇霉素等大环内酯类抗生素的去除效率也非常低。对于紫外线/过氧化氢工艺，在紫外线剂量为923毫焦/平方厘米时，39种药物的去除效率可达90%，这表明通过将过氧化氢与紫外线工艺相结合，有可能降低有效去除药物所需的紫外线能量。
