Intelligent scientific and technical wetland unit combined river-way ecological remediation system

Abstract

The invention relates to an intelligent scientific and technical wetland unit combined river-way ecological remediation system. The system is arranged on two sides of a river way and the bottom of theriver way, at least one high-yield treatment unit is arranged on the sides of the river way and comprises a high-yield vertical flow wetland module and a high-yield surface flow wetland module, and the high-yield vertical flow wetland module is used for receiving and treating external water and conveying the external water treated by the high-yield surface flow wetland module into the river way.By utilizing the combined river-way ecological remediation system, the problem that a single wetland unit is low in treatment efficiency is solved, and the river-way ecological remediation system canbe utilized for solving the problems of the pollution treatment of different scales of river ways and complex pollution sources of the river ways when being flexibly combined with multiple other wetland modules; and the river-way ecological remediation system can also be utilized for treating different emergency weather conditions such as high instant flow in a daily weather and a storm period, high continuous water yield in the storm period and few water bodies in a drought period as well as emergency pollution sources.

Description

technical field [0001] The invention relates to the technical field of river water pollution control, in particular to a river ecological restoration system combined with intelligent technological wetland units. Background technique [0002] With the rapid development of urbanization and industrialization, more and more rivers have been polluted to varying degrees. If they are not treated in time, the rivers will develop into black and smelly rivers. Traditional river management methods mainly include: 1. Building rubber dams, sluice dams and other structures to intercept river channels, which can intercept slightly larger floating objects. This method is hardened facility construction, which focuses on interception and cannot be realized. The function of ecological restoration of the river channel; 2. Cleaning up silt, diverting water and changing water, by cleaning up the silt deposited on the bottom of the river and replacing the sewage in the river, the effect of river m...

Problems solved by technology

Traditional river management methods mainly include: 1. Building rubber dams, sluice dams and other structures to intercept river channels, which can intercept slightly larger floating objects. This method is hardened facility construction, which focuses on interception and cannot be realized. The function of ecological restoration of the river channel; 2. Cleaning up silt, diverting water and changing water, by cleaning up the silt deposited on the bottom of the river and replacing the sewage in the river, the effect of river management can be achieved. This method can only solve one stage in a single implementation For water quality problems, the treatment effect lasts for a short time and needs to be implemented periodically; 3. Build a water treatment system and an ecological slope next to the river, and lead the sewage in the river and the sewage flowing out of the river to the water treatment system and the ecological slope At present, this method mainly adopts a single method, such as planting, ecological pond, vertical flow, etc., but no effective combination is used; 4. Physical aeration, the sludge at the bottom of the river and The river water is aerated to achieve the purpose of degrading pollutants. This method can only remove less pollutants, and the removal efficiency is not high; 5. Biological dosing, by adding microorganisms and chemicals to the river to eliminate pollutants , this way is prone to secondary pollution

At present, in the process of river course management, the above-mentioned treatment methods have not been effectively combined flexibly, and a treatment system has not been formed. The applicability is narrow, the wetland part is small, the treatment module is single, the treatment degree is not high and the effect is not obvious, and the sludge is inconvenient. , the odor problem is difficult to solve
