Common ecological restoration methods for river regulation
Strengthening river regulation and improving river water quality are of great significance to improving people's living environment. As a specialist in sewage treatment equipment, Kinglv environmental protection has participated in river pollution control projects many times and is familiar with various methods of river rehabilitation. Today, we share common ecological restoration methods.
1. Microbial treatment
Microorganisms specially cultivated and screened are added to the river channel as a growth promoter to accelerate the decomposition of harmful substances in the river channel, convert it into harmless substances, promote the purification of water resources in the river channel, and promote the river channel. The growth of self-owned microorganisms enhances the natural degradation ability of river channels for pollutants and improves the self-cleaning function of river channels.
2. Relying on aquatic plants to purify
The method of purifying aquatic plants can purify sewage to a large extent. This method essentially uses aquatic plants capable of absorbing degrading pollutants to purify, but it should be noted that no matter what kind of aquatic plants are If there is a certain load limit, if the water pollution is too strong, it will exceed the limit that the aquatic plant can bear, which is not conducive to its growth, and can not achieve the purpose of purification. Therefore, the application of this method must be less serious. When it is done.
3. Construction of constructed wetlands
The constructed wetland can not only treat wastewater but also has beautiful appearance. It has the advantages of protecting the ecological environment, high efficiency and low cost, and can be directly used for treating domestic sewage. It is a wastewater treatment system consisting of matrix, plants and microorganisms. When the sewage passes through, the sewage is intercepted, and then the pollutants are filtered. The harmful substances are adsorbed near the plants, and the pollutants are absorbed by the plants.
