Composite drainage net is a drainage system that combines different materials and functions, which can effectively prevent and control water pollution. It achieves the reduction and prevention of water pollution through measures such as centralized treatment of sewage, purification of rainwater, and improvement of water resource utilization. The following is the effect of composite drainage network on water pollution prevention and control:


Use advanced treatment technology to realize centralized treatment of sewage. The composite drainage network adopts advanced sewage treatment equipment, such as biofilm reactors, activated carbon adsorbers, etc., which can efficiently remove organic matter, ammonia nitrogen, phosphorus and other harmful substances in sewage, and reduce the generation and spread of water pollution. At the same time, through the installation of sewage interception ports and interception facilities, sewage can be effectively collected and discharged, preventing it from directly entering natural water bodies, and protecting the overall water quality of the water environment.


Optimize the treatment of rainwater to reduce runoff pollution. The composite drainage network adopts a variety of rainwater treatment methods, such as flood storage and detention areas, wetland treatment, etc., which can effectively promote the seepage and natural purification of rainwater, and reduce the impact and pollution of rainwater runoff on water bodies. In addition, the composite drainage network can also collect and utilize rainwater resources, such as irrigation, landscaping, etc., to improve the efficiency of water resource utilization.


Improve the comprehensive utilization rate of water resources. The composite drainage network separates the rainwater and sewage, so that the sewage can be treated in a centralized manner, and the rainwater can be properly utilized, realizing the separate utilization of sewage and rainwater. Through the treatment of sewage and the reuse of rainwater, the comprehensive utilization rate of water resources can be improved and the waste of water resources can be reduced.


Reduce urban waterlogging and water pollution. Composite drainage network can reduce rainwater runoff and sewage discharge by setting sewage interception outlets, recharge wells and anti-seepage walls, and prevent urban waterlogging. At the same time, the composite drainage network can also collect and treat sewage from roads, construction sites and other places, preventing it from directly entering the water body and reducing the occurrence of water pollution.


Protect the long-term stability of the water ecological environment. By diverting and treating sewage and rainwater, the composite drainage network reduces the possibility of sewage entering the water body and avoids damage to the water ecological environment. At the same time, through the seepage and natural purification of rainwater, the ecological balance of the water body is maintained, and the long-term stability of the water ecological environment is maintained.


Improve the sustainable development capacity of the city. The composite drainage network can improve the sustainable development ability of the city through comprehensive utilization of water resources, reduction of water pollution and prevention of urban waterlogging. It can not only protect water resources and reduce environmental pollution, but also improve the ecological quality of the city and the quality of life of residents, and promote the economic and social development of the city.


In a word, the composite drainage network has played an important role in water pollution prevention and control. It can effectively reduce the generation and spread of water pollution and protect the overall water quality of the water environment through centralized treatment of sewage, purification of rainwater, and improvement of water resource utilization. At the same time, it can also reduce the occurrence of urban waterlogging, protect the long-term stability of the water ecological environment, and improve the sustainable development capacity of the city.
