The water outlet hole is located on the opposite panel of the water inlet hole, the diameter is 2cm, and the distance from the top of the barrel is 10~15cm.

[0094] The use method of the device is as follows:

[0095] For rural households without water quality assessment requirements or using the effluent for farmland and vegetable fields, the biochemical barrel can be directly connected after the septic tank, and then the effluent can be discharged. The treated water can be fully utilized by soil and economic crops for self-purification, which not only reduces the construction investment and operation cost of the sewage treatment device, but also fully realizes the reuse of nutrients in the sewage;

[0096] For rural households in areas with relatively tight land or scattered land, the adjusting barrel, the biochemical barrel and the sedimentation and reuse barrel can be assembled into an integrated sewage treatment device, or connected through a pipeline after the septic tank and connected through a pipeline barrel, so as to fully place the barrel in a suitable place according to the local conditions. The whole can be used in different areas with different terrain characteristics

[0097] The specific value of the biochemical barrel aeration system of the device is determined according to the water quality requirements of the inlet and outlet water. When the apparent bubbles are obviously lower than the bubbles at the completion of debugging, it is determined that the blockage occurs. The aeration pump can be adjusted to the maximum and kept for 10-20 minutes. The amount of attachments on the filler is reduced by gas washing, and the blocked filler is unblocked. Then the exhaust pipe is opened to quickly remove the attachments and the sediment at the bottom of the barrel. Then the normal water inlet and aeration amount are restored. The power system adopts two options of external power supply and photovoltaic + power storage, which can reduce the coordination difficulty during the construction period and the power consumption during the operation period.

[0098] The use method includes two types of construction method and operation method.

[0099] The low-energy consumption fabricated sewage treatment device for rural households in the application has the following advantages:

[0100] The adjustment unit, biochemical unit and sedimentation and reuse unit in the use method of the application can be flexibly arranged according to the location of the scattered household septic tank outlet and the terrain during the construction period. They can be placed in a complete set or arranged in series according to the terrain and topography, which improves the application range of the overall device, especially in small plots or hilly and mountainous areas. At the same time, the same functional units can be arranged in series or parallel, which improves the breadth and applicability of the device in scale use.

[0101] The power system of the device in the use method of the application is selected according to the acceptance of the project by the local villagers during the construction period. If the villagers have high cooperation degree, external power supply can be directly selected. If the cooperation degree is low and the area is not sensitive to non-water environment, photovoltaic + power storage system can be selected. If the cooperation degree is low and the area is sensitive to non-water environment, photovoltaic + power storage system and external power supply can be selected.

[0102] The power system in the operation method in the use method of the application is selected according to the acceptance of the project by the local villagers. If the villagers have high cooperation degree, external power supply can be directly selected. If the cooperation degree is low and the area is not sensitive to non-water environment, photovoltaic + power storage system can be selected. If the cooperation degree is low and the area is sensitive to non-water environment, photovoltaic + power storage system and external power supply can be selected.

[0103] The biochemical unit in the use method of the application is adjusted according to the water quality during the operation period. The stable and standard aeration value of the biochemical barrel is determined. If the filler is slightly blocked during the operation period, the amount of short-time aeration and the residual material in the barrel can be selectively increased to solve the filler blockage. If the filler is seriously blocked, the filler can be removed and then put into the biochemical barrel to solve the filler blockage.

[0104] In the operation period of the sediment reuse unit in the method of the present application, if the effluent is used as irrigation water, the sediment reuse unit does not need to add slow-release disinfection tablets and can be directly used for irrigation. If the effluent enters a receiving water body with high water quality requirements, slow-release disinfection tablets and phosphorus removal filter fillers must be added to the sediment reuse unit to ensure the water quality of the effluent.

[0105] The above embodiments are only preferred technical solutions of the present application and should not be regarded as limitations of the present application. The protection scope of the present application should be based on the technical solutions recited in the claims, including equivalent replacement solutions of the technical features recited in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present application.
