- Abstract:
- Water ecological restoration measures often prioritize source control and pollution interception, synergistically enhancing water purification through external interception and internal degradation, serving as a crucial strategy in water environment management. However, the foundational work of source control and pollution interception in county?level cities is frequently inadequate, necessitating ecological restoration efforts under conditions of incomplete sewage interception, which undoubtedly poses a significant challenge to urban river ecological restoration. This study focuses on the issue of direct discharge of domestic sewage into drainage ditches, exploring ecological restoration measures for branch drainage canals and the main channel of the Rang River in Ruichang. By implementing the measures of ecological permeable dam + ecological water grass + aeration on the sewage channel, the filtration interception and contact oxidation effects are effectively utilized to degrade directly discharged domestic pollutants, creating conditions for the ecological restoration of the Rang River. By implementing measures such as internal cleaning, external interception, enhanced purification, and system restoration, the goal of restoring the ecological system of Rang River and improving water quality can be achieved.
