| titleOfInvention | Original-position denitrification reactor in flowing water area |
| abstract | The invention discloses an original-position denitrification reactor in a flowing water area. The original-position denitrification reactor in the flowing water area comprises a grit chamber, a hydraulic drop dam, a reaction tank and a retention wall, wherein the retention wall is formed by cobblestones in stacked mode, and the grit chamber, the hydraulic drop dam, the reaction tank and the retention wall are arranged in sequence along the water flowing direction. The lower layer of the reaction tank is filled with a saw dust layer, a polyvinyl chloride (PVC) pipe used to collect denitrification tail water is laid at the bottom of the saw dust layer and is close to the cobblestoned retention wall, water outlets of the PVC pipe are connected with flexible drainage underground pipes, the flexible drainage underground pipes penetrate through the bottom of a riverbed under the cobblestoned retention wall and are exposed on the surface of the downstream riverbed behind the cobblestoned retention wall, and drainage faucets are mounted on water outlets of the flexible drainage underground pipes. A sticky sand layer and a gravel layer are laid side by side on the saw dust layer, wherein the sticky sand layer is close to the retention wall, and the gravel layer is close to the hydraulic drop dam. The denitrification reactor is made of local materials, and is simple to construct and low in cost; the fall changes of the flowing water area from top to bottom can be used to carry out sand settling and hydraulic drop oxygenation treatment, and continuous treatment and purification of a polluted water area can be achieved; and high-concentration nitrogen in streams which flow into lakes or reservoirs, drainage channels, city watercourses and other flowing water areas can be effectively removed. |
