Key Technologies Study for Combined Treatment of Black and Odorous Water and Sediments Using Aeration Technology and Constructed Wetlands

本文针对黑臭水体和黑臭底泥对环境的影响，通过对黑臭水体和黑臭底泥的输入和源解析进行研究，采用曝气生物技术治理，并对工艺参数进行调整，去除水中的悬浮物、有机物、营养盐等污染物，改善水质。从曝气量、曝气间歇时间、曝气位置三个角度分析了曝气治理黑臭水体污染物及黑臭底泥效果，同时采用曝气技术与人工湿地技术有机结合，分析不同条件对水体TN、NH₃-N、TP和COD去除率的影响。最终形成基于曝气技术与人工湿地组合处理黑臭水体污染物及黑臭底泥关键技术，为河道治理提供参考。
This paper addresses the environmental impact of black and odorous water bodies and sediment. By studying the inputs and source analysis of black and odorous water bodies and sediment, aeration biological technology is applied for treatment, and process parameters are adjusted to remove pollutants, such as suspended solids, organic matter, and nutrients, thereby improving water quality. The effects of aeration on the removal of pollutants from black and odorous water bodies and sediment are analyzed from three perspectives: aeration volume, aeration interval, and aeration location. Additionally, the organic combination of aeration technology and constructed wetland technology is used to analyze the impact of different conditions on the removal rates of TN, NH₃-N, TP, and COD in water bodies. Ultimately, a key technology for the combined treatment of pollutants in black and odorous water bodies and sediment using aeration technology and constructed wetlands is developed, providing a reference for river management.
