[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-6 , the present invention provides a technical solution: an enhanced device for a comprehensive ecological interception system, including a rainwater outlet ecological retention zone, an ecological interception net, and a river mouth ecological interception and enhancement system material group. The rainwater outlet ecological retention zone is arranged at each rainwater discharge outlet on the river course. The ecological interception net is horizontally intercepted between the river surface and the river bottom of the river course, and multiple ecological interception nets are arranged on the corresponding river course. The river mouth ecological interception and enhancement system material group is arranged at the confluence of the tributary river course and the main river course.

[0025] Through the setting of the rainwater outlet ecological retention zone, the initial rainwater is purified before being discharged into the river course, reducing the impact of initial rainwater pollution on the water quality of the river course;

[0026] Through the setting of the ecological interception net, the garbage in the river course can be filtered, improving the river course cleaning efficiency and the river course sanitation effect;

[0027] Through the setting of the river mouth ecological interception and enhancement system material group, using the comprehensive treatment measures of plants and microorganisms to reduce the impact of pollutants at the tributary mouth on the water quality of the main river course, thereby realizing the function of the estuary ecological buffer zone.

[0028] The rainwater outlet ecological retention zone includes a fixed pile fence surrounding a quadrilateral. The four sides of the fence are surrounded by tight bamboo fence pieces to form four fence surfaces. The bottom of the fence is sealed with a permeable cloth. A gravel layer, a zeolite layer, and a planting soil layer are sequentially arranged from bottom to top within the upper-opening fence. Emergent plants are planted on the planting soil layer. The emergent plants include one or more combinations of iris, canna, thalia dealbata, and lophatherum gracile.

[0029] The implementation points are at each rainwater discharge outlet. The biological retention zone is 2 meters wide, and the length is adjusted according to the actual situation;

[0030] Implementation method: Use 4-meter-long pine wood piles to surround the edge. Bamboo fence pieces and permeable cloth are arranged inside the pine wood piles to prevent the loss of fillers. The biological retention zone is 0.5 meters deep and filled with fillers such as gravel, zeolite, and planting soil, with filling thicknesses of 0.1 m and 0.2 m respectively. Emergent plants are planted on it, such as iris, canna, thalia dealbata, and lophatherum gracile, etc.

[0031] The ecological barrier net includes fixed pipes, filter nets, and floating balls. The lower ends of the fixed pipes are fixed to the bottom of the river channel, and multiple fixed pipes are evenly distributed on both sides and in the middle of the river channel and are arranged in the same horizontal direction. The bottom edge of the filter net is fixed on the fixed pipes at the bottom of the river channel. Multiple floating balls are evenly arranged on the upper edge of the filter net, and the net surface of the filter net abuts against the fixed pipes through the river water in the river channel.

[0032] At each position corresponding to the fixed pipes on the upper edge of the filter net, a collar is provided, and the filter net and the fixed pipes are matched through the collars.

[0033] The width of the barrier net is 2 meters. The ecological barrier net is fixed with 4-meter-long galvanized steel pipes and driven into the river bottom. The filter net uses an 80-mesh net level for interception, and floating balls are connected above the filter net, and the height can be automatically adjusted according to the water level. The height of the barrier net is flush with the water surface, which does not affect the passage of boats such as cleaning boats. And the pores of the barrier net are relatively large and will not completely block the water. In special situations such as flood seasons, it can be removed and reinstalled after the flood season.

[0034] In case the water quality of the tributary river channel is relatively poor, in order to prevent the direct inflow of the tributary river water and generate a relatively large pollution load at the confluence, ecological interception system strengthening measures can be set up. The material group of the ecological interception strengthening system at the river channel mouth includes combined fillers, ecological substrates, and ecological floating islands. The ecological floating islands are laid on both sides of the river channel, and combined fillers are suspended below both ecological floating islands, and ecological substrates are laid between the two ecological floating islands.

[0035] The ecological substrates sink to the bottom of the river and are evenly arranged in multiple numbers, and the distance between adjacent two ecological substrates is 1 meter.

[0036] Emergent plants are planted on the ecological floating islands and cooperate with the combined packing. A special film-forming material is made of fibers with super strong surface adsorption to transfer more organic pollutants to the surface of the film-forming material. At the same time, a large number of microorganisms attach to the surface of the film-forming material. The micro A / O environment and microporous structure on the surface layer of the film-forming material create suitable conditions for the growth of nitrifying bacteria, denitrifying bacteria and algae. Finally, through the metabolic synthesis of algae and the ammonification, nitrification and denitrification of various bacteria, nitrogen pollution in the water is adsorbed, intercepted and removed, and organic pollutants are adsorbed and biologically oxidized, and finally the organic matter is decomposed or transformed into microbial components, thus purifying the water quality. In the film-forming material water ecosystem, phosphorus in the water body can be removed through the absorption of microorganisms and aquatic plants and the mineralization of microorganisms. For polluted suspended solids, the film-forming material can create a gentle hydraulic environment to accelerate the sedimentation of suspended solids; and promote their full sedimentation during the collision between the suspended solids and the film-forming material; finally, the biological flocculation on the surface of the film-forming material causes the suspended solids to be adsorbed and finally fall to the bottom of the water with the shedding of the biological film.

[0037] An ecological filter island is composed of combined packing, ecological substrates and ecological floating islands. By using the adsorption function of mineral packing, a structure for removing pollutants in water is achieved by adsorbing suspended pollutants in the water body. During rainfall, the floating islands set on both banks can collect surface runoff. When the initial rainwater mixed with pollutants and suspended particles enters the ecological filter island along the riverbank, the filter island has a certain filtering and sedimentation effect on the suspended solids in the water and also has an absorption effect on the pollutants in the water body. The construction area of the filter island is matched with plants for beautification, which can not only provide a certain biological habitat for the river channel, but also provide a place for the attachment and reproduction of microorganisms.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
