Embodiment 1

[0043] The present invention makes full use of the topographic conditions of mountain-type tourist destinations, and provides a multi-stage tubular swirling oxygenated biological filter for sewage treatment based on relevant hydraulic and aerodynamic principles and in combination with the advantages of biological aerated filters. Equipment and treatment methods, it has the advantages of no power, low construction cost, and the use of slope terrain according to local conditions. Solve the problems of facility construction and long-term operation.

[0044] Such as Figure 1-4 As shown, a multi-stage tubular swirl oxygenation biological filter sewage treatment system is composed of a percolation tank 1, a swirl oxygenation tube 2, a biofilter 3 and a vertical flow sedimentation tank 4. The percolation tank 1 is filled with a percolation tank filter material layer 7; the swirling flow oxygenation pipe 2 is composed of a transition section 8, an oxygenation section 9 and a water d...

Embodiment 2

[0050] Embodiment 2 is basically the same as Embodiment 1, and the difference is that Embodiment 2 is a single-stage unpowered tubular cyclone oxygenated biological filter,

[0051] Such as Figure 5 As shown, the sewage treatment system of the tubular swirl oxygenation biological filter is composed of a percolation tank 1, a swirl oxygenation pipe 2, a biofilter 3 and a vertical flow sedimentation tank 4. The percolation tank 1 is filled with a percolation tank filter material layer 7; the swirling flow oxygenation pipe 2 is composed of a transition section 8, an oxygenation section 9 and a water distribution section 10, which are arranged according to the slope of the terrain, and the transition section is provided with an air outlet 5, The oxygenation section is provided with a swirling device 11, and the water distribution section 10 is provided with an air inlet 6; the biological filter 3 and the vertical flow sedimentation tank 4 are separated by a partition, and the bio...

Embodiment 3

[0053] A method for treating sewage in a multi-stage tubular swirling oxygenated biofilter, the steps of which are as follows:

[0054] A, according to embodiment 1 system construction described a kind of multi-stage tubular swirl oxygenation biofilter sewage treatment system;

[0055] B. Sewage enters the infiltration tank 1 from the water inlet pipe, passes through the filter material layer 7 of the infiltration tank, filters out suspended solids, and enters the swirl oxygenation pipe 2;

[0056] C, sewage in the swirl oxygenation pipe 2 swirl flow downwards through the swirl device 11, because the position and the air temperature at the air outlet 5 of the transition section of each swirl oxygenation pipe are higher than the water distribution section 10, so the air From the air inlet 6 of the water distribution section 10, it flows reversely along the pipeline to the air outlet 5 of the transition section 8, and in the oxygenation section 9, it is in convective contact wit...

Abstract

The invention belongs to the field of water treatment and discloses a multi-stage tubular cyclone aeration type sewage treatment system with a biological filter and a treatment method. The system mainly comprises a percolation tank, a cyclone aeration pipe, the biological filter and a vertical flow sedimentation tank. The percolation tank is filled with bagged particle filter materials and used for effectively removing suspended matters in sewage by anaerobic percolation. The cyclone aeration pipe comprises a transition section, an aeration section and a water distribution section and used for cyclone aeration of sewage. The biological filter is filled with particle fillers and used for removing contaminants such as carbon, nitrogen and phosphorus under aerobic and facultative conditions by filler attached microorganisms, and the vertical flow sedimentation tank realizes chemical phosphorus removal according to requirements. According to the treatment method, unpowered aeration and degradation of contaminants can be realized, problems of construction and long-term operation of sewage treatment facilities under mountain topography conditions are solved, and low construction cost, extremely low operation cost and simplicity in management and maintenance are realized.

Description

technical field [0001] The invention relates to the field of water treatment, and more specifically relates to a sewage treatment system and a treatment method of a multistage tubular swirl oxygenated biological filter. Background technique [0002] Mountain-type tourist destinations are different from other types of scenic tourist destinations based on natural landscapes such as seashores, lakes, rivers, and karst caves, and have unique ecological and water environment characteristics. Because most of the mountains have large undulations, low water storage capacity, strong water erosion, wind erosion or even freeze-thaw action, or bare bedrock, or shallow soil layers, and slow plant growth, the self-regulating ability of the ecosystem is very low. Under the interference of natural force and man-made, it is easy to change. Any excessive and unreasonable development and utilization will destroy the landscape, reduce the living space of animals and plants, and cause the declin...
