the invention provides an in-situ recycling system for rural domestic sewage treatment facility effluent, which is shown in fig. 1, and comprises a fish pond 104, a first planting bed 102, a second planting bed 103 and a water supply pump 402; at the altitude, the first planting bed 102, the second planting bed 103 and the fish pond 104 are arranged in sequence from top to bottom; the water supply pump 402 is used to deliver water from the fish pond 104 to the first planter bed 102.
Based on the structure, the invention is characterized in that eutrophic water in the fish pond 104 is conveyed to the first planting bed 102, bacteria decompose ammonia nitrogen in the water into nitrite in the first planting bed 102, nitrifying bacteria decompose the nitrite into nitrate, the nitrate is absorbed by plants in the water planting pipes as nutrients, meanwhile, the plants purify the water, the water treated in the first planting bed 102 is conveyed to the second planting bed 103 after passing through the overflow weir 105, the water in the first planting bed 102 is conveyed to the second planting bed 103, bacteria can decompose ammonia nitrogen in the water into nitrite in the second planting bed 103, nitrifying bacteria decompose the nitrite into nitrate, the nitrate is absorbed by plants in the water planting pipes as nutrients, meanwhile, the plants purify the water in a deeper step, and the water discharged from the overflow weir 105 of the second planting bed 103 is returned to the fish pond 104. Through the circulation, the water quality of the reclaimed water can be improved, the eutrophic water can be converted into water suitable for aquatic organisms to survive, and meanwhile, the nutrient substances in the eutrophic water can be used as fertilizer for plants, so that the aim of changing waste into valuables is fulfilled, the waste of water resources is reduced, and the recycling channel of the reclaimed water is increased. In addition, at the altitude, the first planting bed 102, the second planting bed 103, and the fish pond 104 are arranged in sequence from top to bottom; thus, after the eutrophic water is pumped up to the first planting bed 102, the eutrophic water flows into the second planting bed 103 and the fish pond 104 from top to bottom, and only one water supply pump 402 is needed, so that the operation cost is relatively low. The required water pipes are reduced, and the blockage of the water pipes can be reduced relatively.
In the present invention, a heating device is provided in the fish pond 104, and the heating device is electrically connected to and controlled by an external control system. The heating device is convenient for fish discomfort caused by too low temperature in the water tank when the air temperature is low, and the temperature detection device is also arranged in the fish tank 104 and is connected with an external control system; the temperature detection device detects the water temperature in the fish pond 104 at any time and feeds the water temperature back to an external control system in real time, and the external control system controls the operation of the heating device in real time according to the information fed back by the temperature detection device.
In the invention, the first planting bed 102 and the second planting bed 103 are provided with overflow weirs, when the water in the first planting bed 102 reaches a certain height, the water overflows to the second planting bed 103 through the overflow weirs 105, and when the water in the second planting bed 103 reaches a certain height, the water flows back to the fish pond 104 through the overflow weirs 105.
In the present invention, nitrate concentration detection means are provided in the first planting bed 102 and the second planting bed 103. Although the eutrophic water body can convert nitrate to be absorbed by plants, the condition that the concentration of nitric acid is insufficient or too high exists, so the nitrate concentration detection device 9 is arranged to detect the concentration of nitrate in water at any time, nitrate is added to improve the concentration when the concentration is insufficient, and water is added to dilute the concentration when the concentration is too high so as to ensure the normal growth and development of plants.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
