Abstract

The invention relates to a method for ecologically restoring water by full-space in-situ nitrogen and phosphorus interception. The method comprises the following steps: (1) setting a unit bio-film carrier structure; (2) immobilizing the bio-film carrier; (3) controlling a pollution source discharge opening or the angle of a rain water runoff pollution source merging into a water body; and (4) setting an ecological floating bed. According to the method, combination of the ecological floating bed technology and the bio-film technology is adopted, the bio-film carrier is set to be a semi-closed basket structure, so that the in-situ bio-film culturing effect can be improved, the bio-film culturing speed is high, the effect is good; the layout of the ecological floating bed and the bio-film is optimized on the basis of the pollutant transmitting and spreading properties in the stream junction region, and in-situ nitrogen and phosphorus interception and treatment on the important pollution source and pollution region of polluted water can be realized. The method has strong adaption to environmental temperature changes and water flowing speed changes, has a good nitrogen and phosphorus removing effect, and can be applied to nitrogen and phosphorus interception and treatment for urban inland water areas.

Description

technical field [0001] The invention relates to a full-space in-situ nitrogen and phosphorus interception water ecological restoration method, which belongs to the technical field of water treatment. Background technique [0002] Ecological floating beds are usually used for ecological restoration of urban and rural water pollution or construction of urban wetland scenic spots and so on. The buoyancy of the floating bed is used to support the aquatic plants, so that the aquatic plants can grow in a fixed area, so that the aquatic plants absorb and degrade the pollutants in the water body through the developed root system; at the same time, the root system also provides a good fixation carrier for the growth of microorganisms in the water, which plays a role of " The role of "biofilm carrier", and finally transfer it out of the water body in the form of harvesting plants, so as to achieve the purpose of purifying water quality. [0003] The biofilm method uses microorganisms...
