Problems solved by technology

[0004] In recent years, people have begun to use constructed wetlands to treat discharged sewage. Constructed wetlands mainly use the physical, chemical and biological synergies of soil, artificial media, plants and microorganisms to treat sewage. However, the existing The soil microbial treatment system of reed beds in dry land is usually built in terraces and pools, which are bulky and occupy a large area; and in winter, plants will hibernate, hindering the treatment of sewage, and at the same time cannot solve the foul smell emitted by sewage

Embodiment 1

[0039] A device for treating sewage by using upland reeds, comprising a plurality of upland reed bed soil microbial treatment systems for connecting with sewage sources, each upland reed bed soil microbial treatment system includes a support tank, and the inside of the support tank is from top to bottom There are reed layer 1, soil microorganism layer 2 and filter layer 13 in sequence.

[0040] A plurality of the upland reed bed soil microbial treatment systems include a pretreatment tank 3, a sedimentation denitrification tank 4, a sedimentation anaerobic tank 5, a contact oxidation tank 6, an intermittent oxidation tank 7, a contact filter tank 8 and a discharge tank connected in sequence 9. The pretreatment pool 3 is used to connect with the sewage source.

[0041] In the first embodiment above, if figure 1 Shown, the present invention comprises pretreatment tank 3, precipitation denitrification tank 4, precipitation anaerobic tank 5, contact oxidation tank 6, intermittent...

Embodiment 2

[0046] The bottoms of the precipitation denitrification tank 4, the precipitation anaerobic tank 5, the contact oxidation tank 6, the intermittent oxidation tank 7, the contact filter tank 8 and the discharge tank 9 are respectively provided with a circulation pump 10, and each circulation pump 10 passes through the sewage The sludge transfer pipe is fixedly connected to the pretreatment tank 3, and each of the sludge transfer pipes is provided with a valve.

[0047] A reservoir 11 is arranged between the pretreatment tank 3 and the precipitation denitrification tank 4, and the pretreatment tank 3 is provided with a lift pump 12, and the lift pump 12 is connected to the reservoir 11 through the first drainage pipe. One side of the reservoir 11 is connected, and the other side of the reservoir 11 is connected with the precipitation denitrification tank 4 through the second drainage pipe.

[0048] The difference between embodiment two and embodiment one is that embodiment two in...

Embodiment 3

[0051] The filter layer 13 includes a volcanic rock layer and a ceramsite filler layer arranged up and down in sequence.

[0052] The difference between embodiment three and embodiment one is that embodiment three provides a specific filter layer 13, the upper surface of filter layer 13 is formed by accumulation of volcanic rock, and the outer surface of volcanic rock is uneven, which increases the filter material and The contact area of ​​sewage pollutants. At the same time, volcanic rock is the best living place for microorganisms, which can improve the removal rate of pollutants such as nitrogen and phosphorus by microorganisms attached to the filter material. The lower layer of volcanic rock is a ceramsite packing layer, which is set in The bottom of the volcanic rock is in close contact with the root system of the plant, which is conducive to better fixing the root microorganisms, so that the microorganisms in the soil can better treat the sewage.

Abstract

The invention discloses a device and a method for treating sewage by using dry land reeds, and belongs to the technical field of sewage treatment.The device comprises a plurality of dry land reed bed soil microbiological treatment systems used for being connected with a sewage source, and each dry land reed bed soil microbiological treatment system comprises a supporting groove; a reed layer, a soil microorganism layer and a filtering layer are sequentially arranged in the supporting groove from top to bottom; the plurality of dry land reed bed soil microbiological treatment systems are constructed to treat sewage, each dry land reed bed soil microbiological treatment system comprises a supporting groove, the occupied area is reduced, a filtering layer is arranged in the groove, a soil microbiological layer is arranged on the filtering layer, and drought-resistant and cold-resistant plants such as reeds are planted in the soil microbiological layer. The root system of the reed can be inserted into the sewage in the supporting groove after growing, nitrogen and phosphorus in the sewage are absorbed and treated, impurities and pollutants in the sewage can be treated by microorganisms, and the problem that the sewage emits odor is solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment device and a treatment method using dryland reeds. Background technique [0002] In recent years, my country's sewage treatment has achieved unprecedented development. With the improvement of people's living standards and the continuous acceleration of urbanization, the demand and consumption of corresponding fresh water resources are also increasing. Sewage treatment plants have played a huge role in solving the problem of water pollution in our country, and have greatly alleviated the crisis of water pollution in our country. As the source and indispensable resource of human survival, water was generally believed to be inexhaustible, resulting in an extreme shortage of water resources and deteriorating water quality, which brought a series of threats to the survival and development of cities. ecological environment problems. [0003] my...
