Embodiment 1

[0029] see figure 1 , Figure 4-6 As shown, the present embodiment 1 provides a rural domestic sewage treatment system, which includes:

[0030] Septic tank 1

[0031] The purification tank 1 is buried under the permafrost layer, and the construction should be carried out according to the local geological and climate conditions. The purification tank 1 has a casing 11, and an insulation layer 111 is provided outside the casing 11. The insulation layer 111 can adopt common insulation materials such as glass wool, foamed polyurethane, and the like. The casing 11 has a water inlet 112 and a water outlet 113, and the casing 11 is divided by several partitions 12 to form five cavities. The partitions 12 have openings that communicate with two adjacent cavities. The five cavities are connected sequentially.

[0032] Along the water flow direction, the five cavities are inclusion removal tank 13 , anaerobic filter bed tank 14 , carrier flow tank 15 , sedimentation tank 16 and dis...

Embodiment 2

[0055] see figure 2 As shown, the main difference between Embodiment 2 and Embodiment 1 is that: this Embodiment 2 does not use the solar heat collecting device 2 , and replaces it with a wind energy heating device 4 .

[0056] The solar energy heating device 4 includes a fourth temperature sensor, a solar power generation device 44 , a wind power generation device, a solid heat storage block 41 and a second heat exchange tube 42 . The solid heat storage block 42 is pierced with heating wires, and the heating wires are connected to solar power generation equipment and wind power generation equipment. The solid heat storage block 41, the electric heating wire and the second heat exchange tube 42 are in close contact with each other to realize mutual heat exchange; the solid heat storage block 41 can be heated by the electric heating wire for heat storage, and the second heat exchange tube 42 can be heated by the electric heating wire When the temperature rises, when the solar...

Embodiment 3

[0060] see image 3 In this embodiment 3, the wind energy heating device 4 and the solar heat collecting device 2 are installed at the same time, and the wind energy heating device 4 and the solar heat collecting device 2 are connected to the first heat exchange tube 18 at the same time. The specific structures of the wind-solar energy heating device 4 and the solar heat-gathering device 2 are as in Embodiment 1 and Embodiment 2. At this time, the cloud management platform 6 can select an operation strategy according to the specific working conditions collected. In the present embodiment 3, the cloud management platform 6 mainly includes:

[0061] A temperature acquisition module, configured to acquire temperature information of the first temperature sensor, the second temperature sensor, the third temperature sensor, the fourth temperature sensor and the fifth temperature sensor;

[0062] The judging module stores a set threshold value related to the first temperature senso...

Abstract

The invention relates to a rural domestic sewage treatment system. The system comprises a purification tank, a wind-solar energy heating device, a solar energy heat collecting device, an air heating device and a cloud management platform; heat exchange pipes are arranged in an anaerobic filter tank and a carrier flowing tank of the purification tank, and the solar energy heat collecting device andthe wind-solar energy heating device are used for transforming wind energy and solar energy into heat energy of hot water, and inputting the hot water to the heat exchange pipes. The air heating device is connected with an air pump used for being configured indoors, and an air vent of the air pump is communicated with an aeration pipe of the carrier flowing tank through a breather pipe; moreover,based on nodes of the system, the cloud management platform monitors an operation strategy of a data remote intelligent control system. The domestic sewage treatment system is configured with multiple auxiliary heating means of solar heating, wind-solar energy heating, indoor air heating and the like, and according to local real-time working conditions, the operation strategy is chosen, so that the operation cost of heating is greatly reduced.

Description

technical field [0001] The invention relates to rural sewage treatment and resource utilization, in particular to a rural domestic sewage treatment system. Background technique [0002] At present, the activated sludge method is commonly used in most urban sewage treatment plants. With the development of rural areas, it has gradually become one of the mainstream solutions for rural sewage treatment and resource utilization. [0003] However, in the northern region and the western alpine region of China, the sewage treatment effect is greatly affected by the ambient temperature. With the decrease of water temperature, the activity of activated sludge gradually decreases, the sedimentation becomes worse, and the removal of organic matter, nitrification and denitrification are greatly affected. Big hit. When the temperature is lower than 15°C, the activity of microorganisms at room temperature will drop sharply, and the nitrification effect will be significantly reduced; when ...
