After the irrigation of unconventional water, on the one hand, the serious non-point source pollution problem caused by direct irrigation of untreated sewage can be avoided, and important nutrients for plant growth can be provided, soil organic matter can be increased, and soil fertility and productivity level can be improved. On the other hand, the input of excessive nutrients, toxic chemicals and pathogens in the unconventional water into the environment ecosystem can also cause a certain degree of environmental pollution, which may endanger the environment and human health. Irrigation with treated unconventional water can improve the utilization efficiency of nitrogen, phosphorus and other nutrient substances in irrigation water, save fertilizer, water and increase yield, and reduce the input of excess pollutants into the environment ecosystem, which has important significance for the alleviation of China's water resources crisis, the prevention and control of non-point source pollution and the promotion of circular economy development.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific implementation of the utility model is described in detail below in combination with the drawings.In the following description, a lot of specific details are set forth in order to fully understand the utility model.However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific implementation.

[0021] As shown in Figure 1 The dry area rural multiple water source collection and comprehensive pretreatment wetland device provided by the embodiment of the utility model comprises a concrete pool 1, a water treatment pool 2 and a water storage regulating pool 3 are arranged on the inner side of the concrete pool 1, and the water treatment pool 2 is located upstream of the water storage regulating pool 3.

[0022] The water treatment pool 2 is internally sequentially provided from top to bottom with a soil layer 4, a harmless solid waste mixture layer 5 and a gravel layer 6, and salt-tolerant aquatic plants 7 (such as cattails, water chives, salt pines and reeds) are planted on the upper side of the soil layer 4;

[0023] The water storage regulating pool 3 is communicated with an external force pump through a first water taking pipe 8 at the upper end, the water storage regulating pool 3 is communicated with a water level siphon pump 9 at the lower end on the outer side, and the water outlet end of the water level siphon pump 9 is communicated with an irrigation pipeline 10 and a second water taking pipe 11.

[0024] The length, width and height of the concrete pool 1 are 4-5 meters * 1.5-2 meters * 1.5-2 meters, and the size of the water treatment pool 2 and the water storage regulating pool 3 is determined according to requirements (for example, length, width and height: 2-2.5 meters * 0.75-1 meter * 1.5-2 meters).

[0025] As preferred, the concrete pool 1 in the embodiment of the utility model is covered with 5-10cm thick hollowed plastic plate 12, the hollowed plastic plate 12 surface is provided with a plurality of aperture 5-10cm hole, salt water resistant plant 7 and first water pipe 8 stretch out from the hole. People can walk through the hollowed plastic plate 12, and it can also be opened and closed. At the same time, it can facilitate the first water pipe 8 to stretch in and pump water.

[0026] As preferred, the water level sensor 13 is arranged on the top of the water storage regulating pool 3. The water level in the water storage regulating pool 3 can be monitored by the water level sensor 13.

[0027] As preferred, the concrete pool 1 in the embodiment of the utility model is located at a lower topography or below a slope, and the height of the water storage regulating pool 3 is 0.05 meters lower than that of the water treatment pool 2.

[0028] As preferred, the thickness of the soil layer 4 is 0-0.5 meters (±0.1 meter), and the distance between the top of the soil layer 4 and the top of the concrete pool 1 is 10-15 cm. The thickness of the harmless solid waste mixture layer 5 is 0.5-1.0 meters (±0.2 meters), and the thickness of the gravel layer 6 is 1.0-1.5 meters (±0.2 meters).

[0029] As preferred, the harmless solid waste mixture layer 5 in the embodiment of the utility model adopts large-particle agricultural solid waste (walnut shells, wood chips, straw residues, etc.) with a diameter of 0.5-1.5 cm, and the gravel layer 6 adopts large-particle gravel with a diameter of 0.5-1.0 cm.

[0030] Multi-source water collection process:

[0031] Rainwater: directly enters from the hollowed plastic plate 12, and the surface runoff formed by the rainwater flows into the soil slope;

[0032] Salt water and brackish water: pumped from the river or underground and poured in by using a water pump and a connecting pipe.

[0033] Rural domestic sewage: pumped from the comprehensive node of the village drainage network by using a water pump and a connecting pipe.

[0034] It should be noted that only the upper part of the rural domestic sewage is pumped, and the underlying sediment solids should not be stirred, otherwise it will cause great pollution to the multi-source mixed water. The proportion of rural domestic sewage to other water sources should be less than 1:8. In this way, the concentration of rural domestic sewage is controlled, the fertility of the reclaimed water is ensured, and the soil of the farmland is not polluted.

[0035] After the multi-source water is treated by the water treatment pool 2, it can be pumped at any time during the water storage process in the water storage regulating pool 3 (i.e. the water intake pool) by using an external force pump or a water level siphon pump 9. After pumping, the water is filtered by using a laminated / sand filter, and irrigation can be performed.

[0036] If irrigation is not needed during the water storage process, after the water is stored, the water level sensor 13 sends a signal, and the water level siphon pump 9 starts to pump water into the external irrigation water storage tank, and is used when needed. If there is too much water, the irrigation pipeline 10 directly uses the green micro-sprinkling irrigation or drip irrigation on the green land above the device.

[0037] Because this mode is suitable for farmland in arid regions with severe water shortage, the drip irrigation mode is preferred when used in farmland, so that the amount of water source and the amount of pollutants can be controlled, and because the drip irrigation flow and water volume are small, the water does not need to be treated too clean, which can reduce costs and will not cause waste and pollution; At the same time, a small amount of nutrients can be irrigated with water, which can improve plant growth efficiency and yield.

[0038] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more; The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and is not indicative or implied that the device or element referred to must have a particular orientation, structure and operation. Therefore, it cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make any modification, equivalent replacement and improvement within the technical range disclosed by the present application, as long as it is within the spirit and principles of the present application.
