Problems solved by technology

Most of the existing constructed wetlands are relatively large-scale wetlands, the operation system is too large, and it is difficult to manage. The wetland matrix is ​​frequently blocked and dredging is difficult. By simulating the matrix, soil, plants and microorganisms in the artificial wetland, various biological Adsorption, absorption and purification of various pollutants in sewage and sludge through comprehensive operations such as chemistry, physics, etc., to achieve the purpose of safe discharge

Embodiment 1

[0024] see Figures 1 to 6 , a detachable constructed wetland domestic sewage treatment system provided by the present invention includes a water collection tank 1 and a body 2, the body 2 includes a first cavity 3 and a second cavity 4, the bottom of the first cavity 3 Several water holes 31 are provided, and the diameter of the water holes 31 is 1 to 2 cm. After the preliminary purification of the first cavity 3, the sewage flows out from the water holes 31 into the second cavity 4. The first cavity 3 is connected to the second cavity 4 through a detachable connecting piece 5, the connecting piece 5 is a sleeve with an internal thread 51, and the first cavity of the external thread 32 is provided at one end and the lower end of the sleeve body 3, the other end of the sleeve is connected with the second cavity 4 with the external thread 32 on the upper end, the internal thread 51 and the external thread 32 are matched and connected, and the second cavity 4 is connected with t...

Embodiment 2

[0029] The difference between this embodiment and embodiment 1 is that: the thickness of the soil layer 8 is 20 cm; the thickness of the zeolite layer 9 is 10 cm, and the particle size is 1 mm; the thickness of the limestone layer 10 is 8 cm, and the particle size is 5 mm. The second cavity 4 is filled with soil layer 11, wheat husk layer or sawdust layer 12, quartz sand layer 13 and ceramsite layer 14 successively from top to bottom, and the thickness of the soil layer 11 is 8cm; the wheat husk layer Or the thickness of the sawdust layer 12 is 15cm; the thickness of the quartz sand layer 13 and the ceramsite layer 14 are both 10cm.

Embodiment 3

[0031] The difference between this embodiment and embodiment 1 is that: the thickness of the soil layer 8 is 30cm; the thickness of the zeolite layer 9 is 20cm, and the particle size is 5mm; the thickness of the limestone layer 10 is 15cm, and the particle size is 8mm. The second cavity 4 is filled with a soil layer 11, a wheat husk layer or a sawdust layer 12, a quartz sand layer 13 and a ceramsite layer 14 successively from top to bottom, and the thickness of the soil layer 11 is 15 cm; the wheat husk layer Or the thickness of the sawdust layer 12 is 25cm; the thickness of the quartz sand layer 13 and the ceramsite layer 14 are both 20cm.

[0032] The working principle of the domestic sewage treatment system of the present invention is as follows: firstly, the domestic sewage is transported to the first cavity 3 and the primary filter 15, and then passes through the soil layer 8 with vegetation, the zeolite layer 9 and the limestone layer 10 for primary purification. , the f...

Abstract

The invention provides a detachable constructed wetland-based domestic sewage treatment system. The detachable constructed wetland-based domestic sewage treatment system comprises a water collecting tank and a body, wherein the body comprises a first cavity and a second cavity; the first cavity is connected with the second cavity through a detachable connecting component; the second cavity is communicated with the water collecting tank; a plurality of supporting nets are arranged inside the first cavity and the second cavity; the first cavity is sequentially filled with a soil layer with a vegetation area, a zeolite layer and a limestone layer from top to bottom; the second cavity is sequentially filled with a soil layer, a wheat husk layer or a wood chip layer, a quartz sand layer and a ceramsite layer from top to bottom. Through the simulation of a variety of biological, chemical and physical properties and the like of a matrix, soil, plants and microorganisms in a constructed wetland, various pollutants in sewage and sludge are comprehensively adsorbed, absorbed and purified, so that the purpose of safe discharge is achieved. The detachable constructed wetland-based domestic sewage treatment system is miniaturized and modularized, the dredging convenience thereof is improved, and the sewage treatment efficiency of the wetland is not affected while the convenience is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a detachable artificial wetland domestic sewage treatment system. Background technique [0002] Constructed wetland is a kind of artificially constructed comprehensive ecosystem similar to natural wetland. Constructed wetland system gives full play to the advantages of biological coexistence, material recycling and resource recycling in the ecosystem, greatly reduces the cost of pollution control, and realizes The purification of sewage prevents the spread and impact of pollutants to obtain the best benefits of sewage treatment. The convenience and operability of constructed wetlands play an important role in practical applications. It helps to remove pollutants in the matrix, and is also conducive to expanding the application range of wetlands and increasing their feasibility. Most of the existing constructed wetlands are relatively large-scale wetlands, the operation ...
