把黄孝河变得更美（我家门前有条河）

Core Viewpoint - The article highlights the successful environmental remediation of the Huangxiao River in Wuhan, showcasing the efforts and innovative solutions implemented to improve water quality and enhance urban resilience [2][6]. Group 1: Project Background - Huangxiao River serves as an important drainage channel in Wuhan, with a total length of 10.7 kilometers, comprising a 5.3-kilometer underground section and a 5.4-kilometer open channel [3]. - The river previously suffered from severe pollution, with black water and foul odors, prompting the need for comprehensive water environment management [3][4]. Group 2: Project Implementation - In 2016, the first phase of the Huangxiao River and Airport River water environment management project was initiated, which included the installation of a steel dam to intercept sewage [4]. - The second phase of the project began to address ongoing pollution and drainage capacity issues, leading to the construction of a 250,000 cubic meter underground retention pool and a facility for treating overflow pollution [4][5]. Group 3: Innovative Solutions - The design team conducted extensive research and field studies, ultimately proposing a solution that involved partitioning the large retention pool into multiple chambers to enhance efficiency and reduce maintenance pressure [5]. - The project resulted in the construction of three underground retention pools with a total capacity of 450,000 cubic meters, significantly improving the control of overflow pollution during rainy seasons [5]. Group 4: Project Outcomes - The retention pools were completed in December 2021 and have been operational since September 2022, successfully maintaining the water quality of Huangxiao River at Class IV or above [6]. - The area above the retention pools has been transformed into a park, enhancing community engagement and quality of life for local residents [6].
