Description

Technical Field

[0001] The invention relates to the technical field of aquaculture tail water treatment, in particular to a device for irrigating crops with agricultural aquaculture tail water. Background Art

[0002] Aquaculture tail water is the water discharged after the water quality changes due to factors such as the metabolism of farmed animals, feed residues, drug use, and various biological activities in the water during the aquaculture process. Aquaculture tail water contains a large amount of organic matter, ammonia nitrogen, nitrite, nitrate, heavy metals and other pollutants. The arbitrary discharge of these substances will enter rivers and lakes through surface runoff, causing eutrophication of water bodies, triggering massive reproduction of algae, forming algal blooms, consuming oxygen in the water, causing hypoxia in the water, and a sharp increase in COD, which in turn affects the survival of aquatic organisms and even affects higher animals through the food chain.

[0003] Ecological damage: Direct discharge of aquaculture tailwater will destroy the ecological balance of the water body and affect the diversity of aquatic organisms. For example, excessive nutrients will cause some aquatic plants to overgrow, while other aquatic organisms may die due to lack of oxygen or deterioration of water quality.

[0004] Disease transmission: Organic matter in aquaculture tail water is a nutrient for pathogens, which can provide conditions for the reproduction and growth of pathogenic bacteria, increase the possibility of disease in farmed organisms, and thus affect human health.

[0005] Soil pollution: The discharge of aquaculture tail water may also cause soil pollution, especially in coastal areas, where the discharge of aquaculture tail water may affect the surrounding farmland and soil quality.

[0006] The existing aquaculture tailwater treatment methods are divided into the following situations:

[0007] 1. Some farmers may directly discharge aquaculture tail water into nearby water bodies (such as ditches, pits, rivers), which may cause pollution to the surrounding water environment.

[0008] 2. Simple sedimentation: Some farmers may use a simple sedimentation method to allow the solid particles in the tail water to settle to the bottom of the water, and then discharge the upper water. Although this method can remove some solid impurities, it has limited effect on removing harmful substances dissolved in water.

[0009] 3. Biological treatment: Some farmers use microorganisms in the water to purify the tail water naturally. For example, by planting aquatic plants (water hyacinth, duckweed, reed, etc.) in the breeding pond, the plants absorb the nutrients in the water. However, this method has a slow purification efficiency and high manpower and material costs. At the same time, microorganisms will also participate in the water purification process.

[0010] 4. Chemical treatment: Some farmers may use some chemical agents to treat aquaculture tailwater, such as disinfectants, flocculants, etc., to kill pathogens in the water and remove some pollutants. However, during use, some farmers do not regulate the dosage, which will have adverse effects on the water ecosystem.

[0011] In summary, most of the existing aquaculture tail water is discharged directly into the river, which not only causes waste of resources, but also causes water pollution. The aquaculture tail water cannot be fully utilized. Therefore, an agricultural aquaculture tail water irrigation crop equipment is provided. Summary of the invention

[0052] Working principle: A method for treating aquaculture tail water by using an agricultural aquaculture tail water irrigation equipment. The equipment is used to treat aquaculture tail water, and then the equipment is used to irrigate the crops with the aquaculture tail water. The specific operation process is as follows:

[0053] Step 1: First, the aquaculture tail water is transported to the treatment pool, and conventional irrigation water is added to the treatment pool at a ratio of 3:7. In the treatment pool, polyaluminium chloride flocculant is added for stirring and flocculation treatment;

[0054] Step 2: Connect the water inlet pipe 9 to the water pump in the tailwater tank through a hose;

[0055] Step 3: According to the planting width of the field, the distance between the anti-skid rollers 205 at the bottom of the trolley frame 1 is controlled by the remote control device so that the anti-skid rollers 205 can move in the field ditch;

[0056] Specifically: first, the first motor 203 is used to drive the roller mounting frame 204 to rotate, thereby adjusting the moving direction of the anti-skid roller 205, and then the first electric telescopic rod 208 is used to push the slider 206 to move, thereby driving the anti-skid roller 205 to move to both sides. Under the push of the first electric telescopic rod 208, the third motor on the anti-skid roller 205 also works, thereby driving the anti-skid roller 205 to rotate. After the distance between the two anti-skid rollers 205 is adjusted, the first motor 203 is used to drive the roller mounting frame 204 to rotate, thereby rotating the roller mounting frame 204 to a suitable angle, and then the third motor is used to drive the anti-skid roller 205 forward or backward;

[0057] When the height of the equipment needs to be adjusted to prevent the equipment from being too low and causing damage to the seedlings, the hydraulic oil pump in the hydraulic control box 7 can be controlled to work, so that the hydraulic oil in the hydraulic oil tank is sucked into the hydraulic cylinder 201, and the telescopic rod of the hydraulic cylinder 201 is extended to adjust the height of the entire equipment;

[0058] Step 4: While the entire equipment is moving, turn on the water pump to pump the flocculated tail water in the tail water pool into the tail water treatment box 3, open the solenoid valve at the bottom of the reagent tank 302, and add a certain amount of disinfectant to disinfect the flocculated tail water. When the equipment moves forward, it will shake, so that the tail water and the disinfectant are fully stirred. The tail water is filtered through the first filter screen 308 and the second filter screen 309. The substances filtered out by the first filter screen 308 (coarse filter screen) include uneaten feed, leftover bait, feces of aquatic animals such as fish and shrimp, algae residues, dead small fish and shrimp or large organisms, as well as mud and other debris in the water body; the purpose of filtering is to eliminate the risk of large particles clogging the equipment and pipelines, and to prevent these large particles from entering the fine filter screen to reduce the risk of affecting the operation of the entire equipment.

[0059] The second filter 309 (fine filter) mainly filters tiny suspended particles, such as small feed powder, decomposed aquatic animal feces, small microorganisms, algae, etc. It can also filter out some colloidal substances that may exist in the aquaculture water, such as dissolved organic matter and protein substances. The second filter can intercept them more accurately. Purpose: It can further improve the water quality. By removing the colloidal substances and suspended organic matter in the aquaculture water, the water body can be made clearer, the turbidity of the aquaculture water can be reduced, and it is closer to the recycling standard and emission standard. On the other hand, it can also prevent certain tiny pollutants from being discharged into natural water bodies. Otherwise, these pollutants may affect the growth and health of other organisms, cause disease infection, reduce the oxygen dissolving capacity of the water body, etc. Then, the first centrifugal pump 8 is used to work to transport the treated tail water in the tail water treatment box 3 to the water spray plate 403 through the water pipe 405, and the water is sprayed out through the water spray port on the water spray plate 403;

[0060] Step 5: The gears in the reduction box 406 are driven to rotate by the second motor 407, thereby driving the water spray plate 403 to rotate, so as to adjust the water spray angle, thereby adjusting the range of the water spray. The solenoid valve on the connecting pipe 404 can also be opened to allow the spray port on the spray plate 402 to spray water mist, so that the water mist can be sprayed on the leaves of the crops while spraying water.
