Abstract

Excessive ammonia is a common pollutant in the wastewater, which can cause eutrophication, poison aquatic life, reduce water quality and even threaten human health. Ammonia in aqueous solution was converted using various systems, i.e., ozonation (O), ultrasound (US), catalyst (SrO-AlO), ultrasonic ozonation (US/O), ultrasound-enhanced SrO-AlO (SrO-AlO/US), SrO-AlO ozonation (SrO-AlO/O) and ultrasound-enhanced SrO-AlO ozonation (SrO-AlO/US/O) under the same experimental conditions. The results indicated that the combined SrO-AlO/US/O process achieved the highest NH conversion rate due to the synergistic effect between US, SrO-AlO and O. Additionally, the effect of different operational parameters on ammonia oxidation in SrO-AlO/O and SrO-AlO/US/O systems was evaluated. It was found that the ammonia conversion increased with the increase of pH value in both systems. The NH(aq) is oxidized by both O and ·OH at high pH, whereas the NH oxidation is only carried out through ·OH at low pH. Compared with the SrO-AlO/O system, the ammonia conversion was significantly increased, the reaction time was shortened, and the consumption of catalyst dosage and ozone were reduced in the SrO-AlO/US/O system. Moreover, reasonable control of ultrasonic power and duty cycle can further improve the ammonia conversion rate. Under the optimal conditions, the ammonia conversion and gaseous nitrogen yield reached 83.2% and 51.8%, respectively. The presence of -butanol, CO, HCO, and SO inhibited the ammonia oxidation in the SrO-AlO/US/O system. During ammonia conversion, SrO-AlO catalyst not only has a certain adsorption effect on NH but accelerates the O decomposition to ·OH.

摘要

过量的氨是废水中常见的污染物，它会导致富营养化，毒害水生生物，降低水质，甚至威胁人类健康。采用各种体系，如臭氧化（O）、超声（US）、催化剂（SrO-AlO）、超声臭氧化（US/O）、超声增强 SrO-AlO（SrO-AlO/US）、SrO-AlO 臭氧化（SrO-AlO/O）和超声增强 SrO-AlO 臭氧化（SrO-AlO/US/O），将氨在水溶液中转化。结果表明，由于 US、SrO-AlO 和 O 的协同作用，SrO-AlO/US/O 联合工艺达到了最高的 NH 转化率。此外，还评估了不同操作参数对 SrO-AlO/O 和 SrO-AlO/US/O 体系中氨氧化的影响。发现两种体系中氨转化率均随 pH 值的升高而增加。在高 pH 值下，氨既被 O 氧化，也被·OH 氧化，而在低 pH 值下，氨的氧化仅通过·OH 进行。与 SrO-AlO/O 体系相比，SrO-AlO/US/O 体系中氨的转化率显著提高，反应时间缩短，催化剂用量和臭氧消耗减少。此外，合理控制超声功率和占空比可以进一步提高氨的转化率。在最佳条件下，氨转化率和气态氮产率分别达到 83.2%和 51.8%。-丁醇、CO、HCO 和 SO 的存在抑制了 SrO-AlO/US/O 体系中氨的氧化。在氨转化过程中，SrO-AlO 催化剂不仅对 NH 具有一定的吸附作用，而且还加速了 O 的分解生成·OH。
