Background Art

[0002] Eutrophication of water bodies is caused by excessive use and development of human life and industrial and agricultural production. Every year, the country invests a lot of energy in governance and prevention and control, and has achieved remarkable phased results, but there is still a long way to go to meet national governance standards. On the one hand, some rivers and lakes have been polluted for a long time and it is difficult to reverse; on the other hand, the backward current agricultural production methods will also cause more or less pollution to the environment. Environmental protection is related to the long-term development of agriculture and society. The main way to control eutrophication of water bodies caused by organic pollution is biological purification. The principle is to remove excessive nitrogen, phosphorus and other elements in the water through biological absorption. The treatment methods mainly include the establishment of ecological wetlands, multi-stage purification pools and ecological floating beds. These treatment methods occupy a large area, the amount of engineering is also large, the reusability of facilities is not high, and there are also requirements for site conditions. A large amount of capital investment is required, and generally no economic benefits are generated. Therefore, apart from state funding, some companies and individuals engaged in planting and breeding production are unable to obtain economic benefits from participating in environmental governance, and are not very enthusiastic about treating eutrophic water. They still continue traditional production methods, relying on increasing inputs to obtain outputs, which in turn aggravates the process of eutrophication of water bodies. Summary of the invention

[0035] Example 2

[0036] The system described in Example 1 is specifically applied to intensive production projects, as follows:

[0037] The eutrophic water body is used as raw material to enter the snail and clams breeding workshop 2 from the water inlet 1, and ring-edge snails and pearl clams are cultivated. The breeding workshop pond 6 is 40 meters long, 20 meters wide and 1.5 meters deep. The breeding workshop pond 6 is provided with an arc frame, which is covered with a sun film in winter to increase temperature and covered with a sunshade net in summer to reduce temperature, so that the water temperature of the breeding workshop is controlled within the range of 20-30°C. The breeding workshop pond 6 is a cement pool or aquaculture film is laid, and the composite board 7 is evenly arranged inside. The composite board 7 is 2 meters long and 1 meter wide, with a rotating shaft 11 at one end and an annular cylinder 8 at one end, and the annular cylinder 8 has a gap. The rotating shaft 11 can be inserted into the annular cylinder 8 of another composite board 7 and rotated at a full angle. The two composite boards 7 are folded into a 45° angle, so that the composite boards 7 are connected end to end, and the total length is equal to the short side length of the bottom of the pond 20 meters, and they are placed in parallel with a spacing of 1 meter in the long side direction. The length direction of a single composite board 7 is a serrated folding board 9, and there are reinforcing rods 10 on the upper and lower sides. After the combined plate 7 is placed, the snail species and the mussel species are put in a suitable place for breeding during the first production, and the raw material water is added to 1.2 meters deep. After two months, there are many young snails, and the method of catching the big ones and keeping the small ones to retain the parent snails per square meter is carried out later. The mussel species are put in a suitable place for breeding according to the hanging bag method of conventional pearl mussels. The combined plate 7 plays the role of precipitation and the organic matter in the raw material water, and can also grow into a layer of biofilm, providing abundant natural bait for the snails and mussels, and along with the continuous breeding of the snails, the whole pond bottom and the combined plate 7 are distributed. Because the snails and mussels have a good precipitation effect on the eutrophication water, about 5 days, when the water becomes clear, the water in the snail and mussel breeding workshop can be all discharged into the crop planting workshop, and then the raw material water of equal amount is added immediately. The snails are harvested once every 3 months or so, and about 0.75 kilograms are harvested per square meter on average each time.

[0038] After the organic matter is removed in the snail and clam breeding workshop 2, the clear raw water contains rich inorganic salts such as nitrogen and phosphorus.

[0039] Crop Planting Workshop 3: Connected to the snail and clam breeding workshop 2 by a distribution pipe, it consists of three shallow pools, each 40 meters long, 20 meters wide, and 0.5 meters deep, and the total volume is equal to that of the snail and clam breeding workshop 2. The shallow pool is divided into 50 planting blocks 13 with a width of 1.5 meters and a length of 8 meters without water flow obstruction, and there is a 0.5-meter-wide passage 12 between the blocks for management and walking. A single planting bed 14 is 20 centimeters wide and 1.5 meters long, with an adjustable height, and includes a fixed frame base 21, a planting trough 22, and a vine frame. The fixed frame base 21 is in the shape of an "I" character, and at the three-pronged intersection of the "I" character, there is a vertical pipe 18 with a height of 1 meter. The two vertical pipes 18 are connected by a 1.5-meter crossbeam 20, and there are adjustment holes and pins on the wall of the vertical pipe 18 for adjusting the height of the vine frame; the vine frame is 1 meter high and has a column 17 at its lower end that can be inserted into the vertical pipe 18 to support the vine frame. The trellis includes a horizontal net 15, a vertical net 16 and a pole 17 from top to bottom. There are also adjustment holes on the pole 17; the planting groove is a "V"-shaped groove, with an upper width of 20 cm, two inclined surfaces of 30 cm width and a length of 1.5 meters. Its two ends are closed, and there are mesh holes 19 in the middle of the two inclined surfaces. The two ends of the "V"-shaped groove are respectively fixed to the upper ends of the vertical pipe 18. When planting non-vine crops in the planting bed 14, there is no need for a trellis; when planting vine crops, a trellis is inserted. When planting water spinach, water celery, melon, etc., solid particles such as diatomaceous earth are used to press the seedlings when the crops are transplanted, and the water level is added to the upper edge of the mesh holes 19. The crop roots extend out of the mesh holes 19 to absorb nutrients in the water.

[0040] After the nutrient salts are removed in the crop planting workshop 3, the water becomes pure, but contains plankton, aquatic insects and crop root and leaf fragments brought in and bred from the raw water.

[0041] Water purification fish workshop 4: connected to the back of the planting workshop 3 through a collecting pipe, and the other end is connected to the outlet pipe 5. The pond of water purification fish workshop 4 is 40 meters long, 30 meters wide and 1.5 meters deep, which is 1.5 times the volume of the snail and clam breeding workshop. The pond of water purification fish workshop 4 is stocked with 300 filter-feeding silver carp, 50 grass carp and 2,000 omnivorous crucian carp, which feed on plankton, aquatic animals and crop root and leaf fragments.

[0042] Raw water adding process: Raw water enters snail and clam breeding workshop 2, crop planting workshop 3, and water purification fish workshop 4 from water inlet 1 in turn, and is then discharged out of the system through outlet pipe 5. When the water in the snail and clam breeding workshop 2 becomes clear, from back to front: two-thirds of the water in the water purification fish workshop 4 is drained, the crop planting workshop 3 is emptied into the water purification fish workshop 4, the snail and clam breeding workshop 2 is emptied into the crop planting workshop 3, and the snail and clam breeding workshop 2 is filled with new raw water to start a new cycle.

[0043] After passing through the water purification workshop 4, the organic matter and nutrients in the water are transformed into snails, clams, fish and economic crops, and the discharged water is transparent low-nutrient water. The total area of ​​the factory is 4,400 square meters, with an annual output of 2,400 kg of snails, with an output value of more than 12,000 yuan; 3,000 kg of crops, with an output value of 9,000 yuan; 300 kg of fish, with an output value of more than 3,000 yuan per mu, and the water quality is also purified. Compared with ordinary planting and breeding, it has achieved significant economic, social and ecological benefits.
