The utility model discloses an implement including following technological effect:
the utility model discloses a distributed rural sewage wetland rapid filtration system in alpine region construction cost is low, can effective treatment sewage, it uses to suit in the more scattered mountain area of population distribution, mountain original region and the former district construction of dun, sewage is in proper order through septic tank, grid equalizing basin, the fast filtering pond of wetland handles the back, it is effectual to get rid of pollution index such as BOD, COD, SS, nitrogen, phosphorus, seldom have the stench and propagate the mosquito and fly phenomenon moreover, especially can effectively solve the winter frostproofing problem in the cold areas in the north.
Drawings
Fig. 1 is a schematic view of the distributed rural sewage wetland rapid filtration system in the alpine region of the embodiment of the utility model.
In the figure: 1. a septic tank; 10. a sewage inlet pipeline; 11. an exhaust hole; 2. a grid adjusting tank; 20. a grid net; 21. solar submersible pumps; 3. a wetland fast filter tank; 4. roadside drainpipe networks.
Detailed Description
The present invention will be described in detail with reference to the following embodiments and the accompanying drawings, wherein the described embodiments are only intended to facilitate the understanding of the present invention, and do not limit the present invention in any way.
Referring to fig. 1, the distributed rural sewage wetland rapid filtration system in the alpine region provided by the embodiment includes a septic tank 1, a grid regulating tank 2 and a wetland rapid filter tank 3; the septic tank 1 comprises a sewage inlet pipeline 10, and the septic tank 1 is connected to the grid regulating tank 2 through a pipeline; the grid adjusting tank 2 is internally provided with a grid net 20 and a solar submersible pump 21, and the solar submersible pump 21 is connected to the wetland fast filter tank 3 through a pipeline. The utility model discloses a distributed rural sewage wetland rapid filtration system in alpine region's sewage treatment flow is: sewage is converged and enters a septic tank 1, suspended organic matters in the domestic sewage are removed by utilizing the principles of sedimentation and anaerobic fermentation, condensate is decomposed at the bottom of the tank, and hydrate in the middle layer enters a grid adjusting tank 2 through a pipeline. 50% -60% of suspended matters can be removed from the septic tank 1. The grid equalizing basin 2 utilizes the grid net 20 to intercept the bigger floater and suspended solid in the aquatic, promotes the wetland fast filter 3 by solar energy immersible pump 21 after homogenization quality of water and the water yield, equalizing basin clearance: and SS: 5 percent. The wetland fast filter 3: the wetland fast filtration system in the alpine region is a combination of an undercurrent type artificial wetland and a fast filtration system, and is suitable for the alpine region. The system is operated as a wetland system when being beneficial to plant growth in summer, and is mainly used as a rapid filtration system for filtration when the weather is cold and the water quantity is small in winter, so that pollutants in water are removed. The wetland rapid filtration system fully utilizes the functions of a biological film growing on the surface of the filler, rich plant roots, surface soil, filler interception and the like, prolongs the retention time, and improves the treatment effect and the treatment capacity.
Referring to fig. 1, specifically, the top of the septic tank 1 is provided with an exhaust hole 11 to avoid high pressure in the other chambers.
