Problems solved by technology

[0002] Sewage treatment has always been the top priority of environmental protection work. With the continuous enrichment of living resources, the nitrogen and phosphorus content in our daily domestic sewage is getting higher and higher, which has seriously exceeded the discharge standard. For rural areas Domestic sewage is a huge irrigation water resource, but if the sewage cannot be treated well, the irrigation water will pollute the land, even affect the growth of crops and pollute the agricultural products, making them inedible, so now more and more More and more places pay attention to the treatment and utilization of domestic sewage in rural areas
[0003] However, in actual operation and use, the existing sewage treatment devices are generally larger in size, and it is difficult for the smaller sewage treatment devices to achieve a higher effect of dephosphorization and nitrogen removal. The utilization and irrigation of sewage cause a large amount of waste of water resources and water pollution. Therefore, a new type of dephosphorization and nitrogen removal device for domestic sewage is needed to solve the above problems

Embodiment 1

[0037] Such as figure 1 As shown, a domestic sewage dephosphorization and nitrogen removal device for agricultural irrigation mainly includes an aeration assembly (1), a filter assembly (2), and the aeration assembly (1) and the filter assembly (2) are connected by pipes; figure 1 , 2 As shown, a plurality of reinforcing columns (4) for strengthening the aeration component (1) and the filter material component (2) are provided between the aeration chamber body (11) and the bottom tank (22). By arranging the reinforcing column (4), the overall stability of the device can be significantly improved, and the connection effect between the aeration chamber body (11) and the bottom tank (22) can be enhanced.

[0038] Such as figure 1 , 2 , 3, the aeration assembly (1) mainly includes an aeration chamber body (11), an annular aeration ring (12), and a central air distribution pipe (13); the upper part of the aeration chamber body (11) is provided with a useful For the filler net ...

Embodiment 2

[0050] Basically the same as Example 1, the difference is that the filter material is composed of 12 parts of ceramsite, 8 parts of zeolite, 7 parts of quartz sand, 4 parts of manganese sand, and 9 parts of volcanic rock according to the number of parts by mass; The filter material prepared by the system has a remarkable effect on the adsorption of nitrogen and phosphorus in domestic sewage.

Embodiment 3

[0052] Basically the same as Example 1, the difference is that the filter material is composed of 15 parts of ceramsite, 9 parts of zeolite, 8 parts of quartz sand, 5 parts of manganese sand, and 10 parts of volcanic rock according to the mass parts; The filter material prepared by the system has a remarkable effect on the adsorption of nitrogen and phosphorus in domestic sewage.

Abstract

The invention discloses a domestic sewage dephosphorization and nitrogen removal device for agricultural irrigation, which mainly includes an aeration assembly and a filter assembly; There are multiple groups of air rings in the lower part of the aeration chamber body, and the central air distribution pipe is arranged in the center of the bottom surface of the aeration chamber body, and the central air distribution pipe is connected with the aeration ball set in the built-in groove of the annular aeration ring through the air guide ring and the air guide pipe; The filter material component includes multiple sets of filter material bins and bottom tanks. The filter material bin is cylindrical and has a built-in rotating filter material bucket. The body is arranged at equal intervals in the circumferential direction between the aeration bin body and the bottom tank, and communicated with the aeration bin body and the bottom tank through pipes. The device of the invention is light and easy to use, can effectively improve the removal effect of nitrogen and phosphorus in biological sewage, is energy-saving and environment-friendly, and is more in line with the use needs of agricultural irrigation.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage dephosphorization and nitrogen removal device for agricultural irrigation.
