摘要:
为缓解C市某污水处理厂尾水潜流人工湿地基质堵塞问题，通过“叉车提升+重力自流”方式将35%的H2O2投加到人工湿地试验单元格。投加H2O2后，试验单元格出水流量从（4.90±0.12） m3/h提升到（6.42±0.25） m3/h；加药后有黄褐色泥水混合物流出，说明H2O2在一定程度上能缓解人工湿地基质堵塞问题。投加H2O2会短暂降低人工湿地的处理性能，但在加药60 d后，对NH4+-N和NO2--N的去除率恢复到加药前水平，对COD、TP、TN、NO3--N的去除率有所提高。微生物群落结构分析表明，投加H2O2可改善好氧环境，这为好氧菌的生长创造了适宜条件，但是会抑制基质内部硝化菌的活性；在加药60 d后，亚硝化菌属Nitrosomonas和反硝化菌属Arenimonas的丰度增加，在一定程度上优化了基质内部微生物群落结构。
Abstract:
Hydrogen peroxide (H2O2) with concentration of 35% was introduced into the experimental cells of a constructed wetland using a combination of forklift lifting and gravity self-flow, to address the issue of media blockage in the constructed wetland caused by the underflow of tailwater from a wastewater treatment plant in City C. After the addition of H2O2, the outflow rate in the test cell increased from (4.90±0.12) m3/h to (6.42±0.25) m3/h. Following the introduction of the chemical, a yellowish-brown mud-water mixture was observed to flow out, suggesting that H2O2 could effectively mitigate the issue of media blockage in the constructed wetland to some extent. The introduction of H2O2 led to a temporary decrease in the treatment efficiency of the constructed wetland. Nevertheless, after dosing for 60 days, the removal efficiencies of NH4+-N and NO2--N reverted to pre-dosing levels, while the removal efficiencies of COD, TP, TN, and NO3--N increased. Analysis of the microbial community structure revealed that the introduction of H2O2 to enhance the aerobic environment provided favorable conditions for the proliferation of aerobic bacteria, yet it suppressed the activity of nitrifying bacteria within the media. After dosing chemical for 60 days, the abundance of the nitrosating bacterium Nitrosomonas and the denitrifying bacterium Arenimonas increased, thereby contributing to the optimization of the microbial community structure within the media to a certain extent.
