Problems solved by technology

[0003] However, due to the complexity of river pollution sources and treatment conditions, it is impossible to use a fixed model to control river pollution. For some river pollution caused by eutrophication, the above-mentioned methods are used to control the effects, costs, and The standard speed is not necessarily ideal

Embodiment Construction

[0021] The present invention will be described in detail below through specific embodiments.

[0022] Choose a suitable area upstream of the river to be treated, and arrange an ecological backflow device based on a photoelectric reactor. This device uses the natural killing and disinfection effects of foamed nickel and ultraviolet rays to stain the water in the pipeline of the flow channel to kill Function to eliminate all kinds of harmful bacteria and viruses in the water body. Afterwards, select the water area to be treated in its downstream, and then salvage the algae in the water as far as possible to clean up, and then start to build the water surface floating bed: select a number of bamboo poles with a diameter of about 80-120mm, and fix them crisscross into a frame with a spacing of 70-80mm. grid. Canna is planted at the intersection of each frame, and the canna is fixed on the floating bed frame by a loop with adjustable circumference, and the loop is set into a double l...

Abstract

A technological process comprehensive treatment method of the urban pre-dam engineering composed of the sewage interceptions method, microorganism method, ecological return flow method, floating bed method and multi-step food chain construction method in the water is provided, which is characterized in that: the ecological return flow method adopts the photoelectric reaction device composed of nickel foam and ultraviolet luminescent tube as the equipment of the upstream water to kill algae and harmful bacteria and the photoelectric reaction device promotes the water flow to accelerate the aerobic-facultative flora growth. In the floating bed method, the benefit of the microorganism method is increased through increasing the light transmission amount of the floating bed. The method of combining the ecological floating bed and the floating plants is adopted to inhibit and clean the algae in the water. The multi-step food chain construction method in the water forms the stepped flora by bank protection plants near the bank, the emergent vegetation, floating plants and sunken plants of various varieties based on different water depth, which effectively converts the organic pollutant such as nitrogen and phosphor in the water with low cost.

Description

Technical field [0001] The invention relates to a comprehensive treatment method for an urban front storage project, which belongs to the category of pollution control technologies or methods for urban small watersheds. Background technique [0002] In the treatment of pollution in some small areas of the city, the comprehensive treatment method using the urban front-repository project has been proved to be a more effective method. For this reason, the present inventor proposed a pollution control method for urban front-reservoir that is characterized by "blocking, suction, fishing, and irrigation" alone, using a combination of sewage interception, ecological floating bed, and aeration spray; The process method of the urban front library project composed of pollution method, microbial method, aeration method and ecological reflux method. [0003] However, due to the complexity of river pollution sources and treatment conditions, it is impossible to use a fixed model to treat river...
