Embodiment 1

[0031] A method for ecological purification of black and odorous river water, comprising the steps of:

[0032] (1) Select a section of the river to be treated with relatively straight banks and relatively gentle water flow, and set up garbage grids in the upstream and downstream of the water flow direction of the river section;

[0033] (2) Constructed wetlands are arranged at intervals perpendicular to the river bank in the river section. The number of constructed wetlands is not less than two. The upstream constructed wetlands are higher than the downstream constructed wetlands. An ecological floating bed is fixed on the surface of the wetland, and the water surface soilless cultivation technology is used to plant aquatic plants on the ecological floating bed, and the downstream artificial wetland is equipped with a microbial strain delivery device in the upstream direction of the water flow;

[0034] (3) Regularly clean up the garbage near the garbage grid, maintain the aq...

Embodiment 2

[0043] figure 1 and figure 2 Shown, a kind of method for the ecological purification of black and odorous river course water body, comprises the steps:

[0044] (1) Select a section of the river to be treated with relatively straight banks and relatively gentle water flow, and set garbage grids 1 at the upstream and downstream of the flow direction of the river section;

[0045] (2) There are two constructed wetlands 2 perpendicular to the river bank in the river section. The upstream constructed wetland 21 is higher than the downstream constructed wetland 22. The water body subsurface velocity of the upstream constructed wetland 21 is much smaller than the river's water flow velocity. The surface of the constructed wetland 2 An ecological floating bed 23 is fixed, and the water surface soilless cultivation technique is adopted to plant aquatic plants 24 on the ecological floating bed 23, and the downstream artificial wetland 22 is provided with a microbial strain feeding d...

Abstract

The invention belongs to the field of ecological treatment of water environment, and discloses a method for ecologically purifying a black and odorous riverway water body. The ecological water body purification of the black and odorous riverway, realized by arranging an artificial wetland in a black and odorous riverway seriously polluted by city sewage and utilizing the comprehensive soil-plant-microorganism action, is less in investment, high in efficiency, stable in treatment effect, low in running cost, convenient to maintain, and has a good landscape ecology effect.

Description

technical field [0001] The invention belongs to the field of water environment ecological management, relates to a method for ecological purification of black and odorous river water, and is especially suitable for the ecological purification of black and odorous river water seriously polluted by urban sewage. Background technique [0002] Eutrophication of water quality is the process of deteriorating water quality due to the enrichment of nutrients such as nitrogen and phosphorus in water. In recent years, with the development of industry and the increase of population, human pollution of water resources has become more and more serious. Industrial wastewater, Urban domestic sewage and farmland fertilizers and pesticides are discharged without treatment, ecological damage and water quality deterioration continue to occur. Eutrophic water will promote the rapid reproduction of algae, some of which will emit a fishy smell. When the algae die and decompose, the COD and BOD va...
