- Abstract:
- Based on the analysis of green drainage system development status around the world, the green concept and connotation of urban green drainage system was revealed, which is safe, low-carbon, efficient, ecological and intelligent. A green drainage system planning process was proposed through research based on the problems of insufficient green concept and system coordination in China’s drainage system planning. The green core evaluation index and evaluation method of drainage system were innovatively constructed to support the green attributes evaluation of the planning scheme. The planning scheme optimization of the drainage system was systematically implemented combing with the critical tasks of pipe network optimization, rainfall pollution control, sewage treatment efficiency improvement, water system construction and water resources recycling. The key technologies in the stages of investigation and analysis of current situation, scheme generation and effectiveness evaluation were sorted out. This work will provide all-round support for the compilation of planning schemes, such as implementation steps, evaluation methods and key technologies, and help the green and high-quality development of urban drainage system.
