Description

[Technical field]

[0001] The present invention relates to the technical field of water body purification in fish ponds, and in particular to a human ecological purification system and method for improving water quality. [Background technology]

[0002] A fish pond is a body of water designed for the capture or cultivation of fish, especially a pond with a structure for enclosing fish. In general, an ideal pond should have the following characteristics: large area, deep water, sufficient sunlight, a water source, good water quality, and easy transportation. This allows for improved fish growth and production, and is also suitable for production management. The current situation regarding water quality control for fish ponds is as follows:

[0003] (1) Regular replenishment of new water Typically, new water is replenished every 7 to 10 days, with 15 to 20 cm of water being added. If the water quality deteriorates, it must be changed. The color of the water should be kept grass green or brown, and transparency should be 30 to 40 cm, but specific standards are measured using a water quality monitoring device. It is also possible to adjust the water quality by periodically adding quicklime. Generally, 1 mu (approximately 667 m) of water is added every two weeks. 2 ) Dissolve 15kg to 20kg of quicklime in water and spread it over the entire pond.

[0004] (2) Strengthening oxygen supply measures Intensive aquaculture ponds should be equipped with dedicated oxygenators. These should be operated between 2:00 and 3:00 pm on sunny days, and whenever there is a risk of oxygen deficiency. Oxygen can also be supplied using chemicals such as oxygen supplements.

[0005] (3) Use of microbial preparations It is necessary to quickly remove leftover food and waste to prevent water pollution. In water bodies with a lot of bottom mud, microbial preparations can be used to improve the bottom sediment and suppress the growth of anaerobic bacteria and viruses, thereby preventing the occurrence of fish diseases and oxygen deficiencies. When fish farming continues for a long period of time in a fish pond, the fish waste ferments at the bottom of the pond, and the ammonia nitrogen concentration in the pond increases. As a result, the water quality deteriorates, it emits a foul odor, plants grow abnormally, and the amount of oxygen in the water decreases. Current water purification methods mainly involve filtering the water using electronic devices or reducing the ammonia nitrogen concentration using chemical means, but they have the problem of being expensive. Especially in the plains of southern China, where water resources are abundant, there are fish ponds in almost every paddy field. Under these circumstances, it is a challenge to utilize the eco-cycle to purify the water in the fish ponds and save the cost of aquaculture. Therefore, a human ecological purification system and method for improving water quality are required. [Prior art documents] [Patent documents]

[0007] SUMMARY OF THE PRESENT DISCLOSURE In order to solve the above technical problems, the present invention provides a human ecological purification system and method for improving water quality. [Means for solving the problem]

[0008] A human ecological purification system for improving water quality includes a fish pond, a microbial purification pond, a rice field, a sedimentation pond, an aeration pond, a first pipe, a second pipe, a third pipe, a fourth pipe, and a fifth pipe. The fish pond has a drainage outlet connected to the water inlet of the microbial purification pond through a first pipe, and the microbial purification pond has a drainage outlet connected to the water inlet of the rice field through a second pipe. The rice field has a drainage outlet connected to the water inlet of the sedimentation pond through a third pipe, and the sedimentation pond has a drainage outlet connected to the water inlet of the aeration pond through a fourth pipe. Furthermore, the aeration pond has a drainage outlet connected to the water inlet of the fish pond through a fifth pipe. A pump is installed in the middle of each of the first pipe, the second pipe, the third pipe, the fourth pipe, and the fifth pipe, and these five pumps provide power to the water flow in the corresponding pipe.

[0009] A supply oxygen pipe having micropores is provided at the bottom of the fish pond, and a first air pump is provided at the air supply end of the supply oxygen pipe to supply oxygen to the supply oxygen pipe. Furthermore, a water quality monitoring device is provided at the edge of the fish pond to monitor water quality parameters. Activated sludge is laid at the bottom of the microbial purification pond. The aeration pond includes a micropore aeration pipe, an aeration tank, an ozone pipe, an air pipe, and an aeration pipe. The micropore aeration pipe is fixed to the bottom of the aeration pond, and an ozone generator and a second air pump are fixed to the edge of the aeration pond. The exhaust port of the ozone generator is connected to the aeration tank through the ozone pipe, and the exhaust port of the second air pump is connected to the aeration tank through the air pipe. Furthermore, the exhaust port of the aeration tank is connected to the air inlet of the micropore aeration pipe through the aeration pipe.

[0010] Furthermore, a feeding device is provided at the edge of the fish pond, and the feeding device is located above the water supply port of the fish pond. The feeding device includes a feeding rack and a remote control, and the feeding rack is fixed to the edge of the fish pond. A feeding tank is provided above the feeding rack, and the bottom of the feeding tank is fixedly connected to a feeding pipe. A remote valve is provided at the bottom of the feeding pipe, and the opening and closing of the remote valve is wirelessly controlled by the remote control. Feeding is performed by remotely operating the remote valve using the remote control, and the fish food is evenly distributed throughout the fish pond by the water flowing through the water supply port of the fish pond. Further, an agitator is fixedly connected to the bottom of the settling tank. The agitator includes an agitator motor and a motor base, and the motor base is fixedly connected to the bottom of the settling tank. The agitator motor is fixed above the motor base, and an agitator fan for agitating the water is rotatably connected to the output shaft of the agitator. The agitator brings the coagulant into sufficient contact with the water, and finally performs a sedimentation treatment.

[0011] Furthermore, the method for purifying water quality using the above-mentioned human ecological purification system for improving water quality includes the following steps:

[0012] S1: Fish seedlings are released into the fish pond for aquaculture. The fish are fed remotely by opening and closing the remote valve at the bottom of the feeding pipe using a remote control, and the water quality of the fish pond is monitored using a water quality monitoring device.

[0013] S2: When the oxygen concentration in the water is monitored to be below 3 mg / L, start the first air pump and let air pass through the micro-pore oxygen supply pipe through the first air pump to improve the oxygen concentration in the water.

[0014] S3: When the ammonia nitrogen concentration in the water is detected to exceed 0.02 mg / L, ecological circulation is initiated. The pump in the first pipe is operated to send the water with ammonia nitrogen exceeding the standard value to the microbial purification pond, and a microbial preparation is added to the microbial purification pond. The amount of the microbial preparation added is 120 to 180 g / m 3 This process produces microbially decomposed water.

[0015] S4: The pump in the second pipe is operated to send the biodegraded water from the biopurification pond to the rice paddy. The plants absorb the ammonia nitrogen in the biodegraded water and purify it, obtaining water for the rice paddy.

[0016] S5: The pump in the third pipe is operated to send the rice field water to the settling tank. A flocculant is added to the settling tank, and the amount of the flocculant added is 100 to 150 g / m 3 This allows the suspended solids in the rice paddy water to settle, yielding settled water.

[0017] S6: The pump in the fourth pipe is operated to send the settled water to the aeration pond. The ozone generator and the second air pump are started, and the second air pump extracts air and mixes it with ozone, which is then aerated into the settled water through the mixed gas pipe. This process sterilizes the settled water, replenishes oxygen, and produces aerated water.

[0018] S7: Operate the pump in the fifth pipe to send the aerated water to the fish pond through the fifth pipe. At this time, the supply water flow rate of the fifth pipe is made to match the discharge water flow rate of the first pipe, forming a closed loop for water purification.

[0019] Furthermore, the microbial preparation is composed of the following weight ratio components: 1-3 parts by weight of protease, 9-15 parts by weight of activated carbon, 9-11 parts by weight of Bacillus subtilis spores, 4-7 parts by weight of lactic acid bacteria, 10-15 parts by weight of Pleurotus eryngii fungus residue, 4-7 parts by weight of quicklime, and 15-20 parts by weight of photosynthetic bacteria. The microbial preparation can effectively decompose fish waste and provide necessary nutrients to rice fields.

[0020] All of the above ingredients are commercially available products, specifically as follows: protease is "NHU-Protease 1000" from Zhejiang Xinhecheng, activated carbon is "HY-AC1000" from Hangzhou Huayuan, Bacillus subtilis spore bacteria is "Haida-BS01" from Qingdao Haida Biological, lactic acid bacteria is "JLB-LAB01" from Junlebao, king oyster mushroom residue is "JL-KOMR100" from Shandong Jinluo, quicklime is "XTC-QL100" from Hunan Xiangtan Chemical, and photosynthetic bacteria is "TB-PSB100" from Zhejiang Tianbang.

[0021] Furthermore, the flocculant is composed of the following weight ratio components: 10-15 parts by weight of pectin, 13-20 parts by weight of diatomaceous earth, 13-15 parts by weight of polyferric chloride, 7-9 parts by weight of polyaluminum silicate, 8-13 parts by weight of polyacrylamide, 4-7 parts by weight of sodium carbonate, and 5-10 parts by weight of disodium ethylenediaminetetraacetate (EDTA-2Na). The flocculant has the effect of settling impurities and mud in rice paddies.

[0022] The above ingredients are also commercially available products, specifically as follows: pectin is purchased from Qingdao Bright Moon Seaweed Group Co., Ltd., diatomaceous earth is industrial grade diatomaceous earth from Shanxi Yunshidai Nano Materials Co., Ltd., polyferric chloride is PFC-I type product from Shandong Tianyi Chemical Co., Ltd., polyaluminum silicate is purchased from Henan Hengchang Environmental Protection Technology Co., Ltd., polyacrylamide is PAM-HP product from Beijing Hengju Chemical Co., Ltd., sodium carbonate is industrial pure soda from Tangshan Sanyou Chemical Co., Ltd., EDTA-2Na is EDTA-2Na product from Shanghai Kaisai Chemical Co., Ltd.

[0023] Furthermore, in step S1, the culture density of fish seedlings is 600-1200 fish / cubic meter. The frequency of remote feeding using a remote control is once at 6-7 am and once at 4-5 pm in the spring and autumn seasons. In summer, feeding is once at 6-7 am, and once at 8-9 am and once at 2-3 pm in winter. The above feeding method is optimal because the water body will be polluted if the feeding frequency is too high.

[0024] Furthermore, in step S4, earthworms are cultivated in the rice paddy. Seeds of the earthworm, the williammenii, and the giant earthworm are introduced into the rice paddy in a mass ratio of 8:1:1, and the introduction amount is 2 to 3 kg / mu (approximately 667 m 2) Cultivating earthworms in rice paddies not only breaks down organic matter to provide the rice with the nutrients it needs, but the earthworms can also be reintroduced into fish ponds as fish food. The ratio of earthworms affects the purification effect of this system, but the inventor's repeated experiments confirmed that setting the mass ratio of seedlings of Echinochloa nigricans, Echinochloa nigricans, and Echinochloa nigricans at 8:1:1 promotes the growth of earthworms and provides optimal results in breaking down microorganisms and organic matter accumulated in the water.

[0025] Furthermore, after harvesting each year, the rice straw is dried in the sun until the moisture content is 3-5%. The dried rice straw is put into a crusher to be crushed, and rice straw pieces are obtained after crushing. The rice straw pieces are 5-10 cm long and are returned to the rice paddies to be used as food for earthworms. By crushing the rice straw and using it as food for earthworms, an ecological cycle is created.

[0026] Furthermore, the treatment time with the microbial preparation in step S3 is 1 to 2 days, and the treatment time with the flocculant in step S5 is 10 to 24 hours. Effect of the Invention

[0027] The beneficial effects of the present invention are as follows: The present invention is characterized by recycling water from a fish pond with water from a rice paddy. Water with a high ammonia nitrogen concentration in the fish pond is decomposed by a microbial preparation in a microbial purification pond, and fish waste and fish food residues are decomposed. The decomposed wastewater is sent to a rice paddy, where the rice absorbs the ammonia nitrogen. Organic matter that has not been decomposed is decomposed by earthworms, and the wastewater is then treated in a settling pond. In the settling pond, suspended matter in the water is settled, and the settled wastewater is sent to an aeration pond, where the organic matter in the water is decomposed by ozone oxidation through aeration, and bacteria in the wastewater are sterilized. In addition, sufficient contact between the air and the water improves the oxygen concentration in the water. The treated water is then returned to the fish pond through the fifth pipe.

[0028] Furthermore, the earthworms are fed to farmed fish as fish food, and rice straw is used as food for the earthworms, thus realizing an ecological cycle.

[0029] The present invention is environmentally friendly and energy-saving, as it purifies water through an ecological method and does not introduce any new pollutants in the process. Moreover, the use of earthworms as fish feed reduces the cost of fish farming. [Brief description of the drawings]

[0052] Compared with Example 3, Example 4 provides a method for purifying water quality using a human ecological purification system to improve water quality, which was tested in a specific fish pond. The method includes the following steps:

[0053] S1: Fish seedlings are released into the fish pond 1 for cultivation. The remote control 152 is used to remotely operate the remote valve 155 at the bottom of the first and fifth feeding pipes 4 to feed the fish. The water quality of the fish pond 1 is monitored using the water quality monitoring device 14. The culture density of the fish seedlings is 600 fish. The frequency of remote feeding is as follows: once each at 6 am and 4 pm in spring and autumn, once each at 6 am in summer, and once each at 8 am and 2 pm in winter. The above feeding method is optimal, as feeding too frequently will pollute the water body.

[0054] S2: When the water quality monitoring result confirms that the oxygen concentration in the water is 2.8 mg / L, start the first air pump 13. Air is passed through the first and second micropore oxygen supply pipes via the first air pump 13 to improve the oxygen concentration in the water.

[0055] S3: When the water quality monitoring results confirm that the ammonia nitrogen concentration in the water is 0.05 mg / L, the eco-cycle is started.

This microbial preparation effectively breaks down fish waste and provides necessary nutrients to rice paddies.

This flocculant causes impurities and mud to settle in the rice field.

[0059] S6: The extraction pump 11 in the fourth pipe 9 is operated to send the settled water to the aeration basin 5. The ozone generator 55 and the second air pump 56 are started, and air is extracted by the second air pump 56, mixed with ozone, and passed through the air mixing pipe 57. This mixed gas is used to disinfect the settled water and replenish the oxygen in the settled water, thereby obtaining aerated water.

[0060] S7: The extraction pump 11 in the fifth first pipe 0 is operated to send the aeration water to the fish pond 1 through the fifth first pipe 0. At this time, the supply water flow rate of the fifth first pipe 0 is made to match the discharge water flow rate of the first pipe 6, thereby forming a closed loop for water purification. EXAMPLES

[0061] Compared with Example 3, Example 5 provides a water purification method using a human ecological purification system to improve water quality, which was tested in a specific fish pond. The method includes the following steps:

[0062] S1: Fish seedlings are released into the fish pond 1 for cultivation.

The frequency of remote feeding is as follows: once each at 6 am and 4 pm in spring and autumn, once each at 6 am in summer, and once each at 8 am and 2 pm in winter. The above feeding method is optimal, as feeding too frequently will pollute the water body.

[0063] S2: If the water quality monitoring result confirms that the oxygen concentration in the water is 2.5 mg / L, start the first air pump 13. Air is passed through the first and second micropore oxygen supply pipes via the first air pump 13 to improve the oxygen concentration in the water.

[0064] S3: When the water quality monitoring results confirm that the ammonia nitrogen concentration in the water is 0.03 mg / L, the eco-cycle is started. The extraction pump 11 in the first pipe 6 is operated to send the ammonia nitrogen water exceeding the standard value to the microbial purification pond 2. A microbial preparation is added to the microbial purification pond 2 at a dosage of 150 g / m 3 The treatment time for the microbial preparation is 1.5 days, and biodegraded water is obtained.

[0065] The microbial preparation is composed of the following weight ratios: 2 parts protease, 12 parts activated carbon, 10 parts Bacillus subtilis spores, 5 parts lactic acid bacteria, 13 parts Pleurotus eryngii residue, 5 parts quicklime, and 18 parts photosynthetic bacteria. This microbial preparation effectively breaks down fish waste and provides necessary nutrients to rice paddies.

[0066] S4: The extraction pump 11 in the second pipe 7 is operated to send the microbially decomposed water in the microbial purification pond 2 to the rice paddy 3. The plants absorb the ammonia nitrogen in the microbially decomposed water and purify it, obtaining water for the rice paddy 3.

[0067] S5: The extraction pump 11 in the third pipe 8 is operated to send the rice field 3 irrigation water to the settling tank 4. A flocculant is added to the settling tank 4 to settle suspended matter in the rice field 3 irrigation water. The amount of flocculant added is 130 g / m 3 The processing time is 18 hours.

[0068] The flocculant is composed of the following weight ratios: 13 parts pectin, 15 parts diatomaceous earth, 14 parts polyferric chloride, 8 parts polyaluminum silicate, 10 parts polyacrylamide, 5 parts sodium carbonate, and 8 parts disodium ethylenediaminetetraacetate (EDTA-2Na). This flocculant causes impurities and mud to settle in the rice paddy.

[0069] S6: The extraction pump 11 in the fourth pipe 9 is operated to send the settled water to the aeration basin 5. The ozone generator 55 and the second air pump 56 are started, and air is extracted by the second air pump 56, mixed with ozone, and passed through the air mixing pipe 57. This mixed gas is used to disinfect the settled water and replenish the oxygen in the settled water, thereby obtaining aerated water.

[0070] S7: The extraction pump 11 in the fifth first pipe 0 is operated to send the aeration water to the fish pond 1 through the fifth first pipe 0. At this time, the supply water flow rate of the fifth first pipe 0 is made to match the discharge water flow rate of the first pipe 6, thereby forming a closed loop for water purification. EXAMPLES

[0071] Compared with Example 3, Example 6 provides a water purification method using a human ecological purification system to improve water quality, which was tested in a specific fish pond. The method includes the following steps:

[0072] S1: Fish seedlings are released into the fish pond 1 for cultivation. The remote control 152 is used to remotely operate the remote valve 155 at the bottom of the first and fifth feeding pipes 4 to feed the fish. The water quality of the fish pond 1 is monitored using the water quality monitoring device 14. The culture density of the fish seedlings is 1,200 fish. The frequency of remote feeding is as follows: once each at 7 am and 5 pm in spring and autumn, once each at 7 am in summer, and once each at 9 am and 3 pm in winter. The above feeding method is optimal, as feeding too frequently will pollute the water body.

[0073] S2: When the water quality monitoring result confirms that the oxygen concentration in the water is 0.29 mg / L, start the first air pump 13. Air is passed through the first and second micropore oxygen supply pipes via the first air pump 13 to improve the oxygen concentration in the water.

[0074] S3: When the water quality monitoring results confirm that the ammonia nitrogen concentration in the water is 0.04 mg / L, the eco-cycle is started. The extraction pump 11 in the first pipe 6 is operated to send the ammonia nitrogen water exceeding the standard value to the microbial purification pond 2. A microbial preparation is added to the microbial purification pond 2, with the amount of the preparation being 180 g / m. 3 The treatment time for the microbial preparation is two days, and biodegraded water is obtained.

[0075] The microbial preparation is composed of the following weight ratios: 3 parts protease, 15 parts activated carbon, 11 parts Bacillus subtilis spores, 7 parts lactic acid bacteria, 15 parts Pleurotus eryngii residue, 7 parts quicklime, and 20 parts photosynthetic bacteria. This microbial preparation effectively breaks down fish waste and provides necessary nutrients to rice paddies.

[0076] S4: The extraction pump 11 in the second pipe 7 is operated to send the microbially decomposed water in the microbial purification pond 2 to the rice paddy 3. The plants absorb the ammonia nitrogen in the microbially decomposed water and purify it, obtaining water for the rice paddy 3.

[0077] S5: The extraction pump 11 in the third pipe 8 is operated to send the rice field 3 irrigation water to the settling tank 4. A flocculant is added to the settling tank 4 to settle suspended matter in the rice field 3 irrigation water. The amount of flocculant added is 150 g / m 3 The processing time is 24 hours.

[0078] The flocculant is composed of the following weight ratios: 15 parts pectin, 20 parts diatomaceous earth, 15 parts polyferric chloride, 9 parts polyaluminum silicate, 13 parts polyacrylamide, 7 parts sodium carbonate, and 10 parts disodium ethylenediaminetetraacetate (EDTA-2Na). This flocculant causes impurities and mud to settle in the rice field.

[0079] S6: The extraction pump 11 in the fourth pipe 9 is operated to send the settled water to the aeration basin 5. The ozone generator 55 and the second air pump 56 are started, and air is extracted by the second air pump 56, mixed with ozone, and passed through the air mixing pipe 57. This mixed gas is used to disinfect the settled water and replenish the oxygen in the settled water, thereby obtaining aerated water.

[0080] S7: The extraction pump 11 in the fifth first pipe 0 is operated to send the aeration water to the fish pond 1 through the fifth first pipe 0. At this time, the supply water flow rate of the fifth first pipe 0 is made to match the discharge water flow rate of the first pipe 6, thereby forming a closed loop for water purification.

[0081] As a result of comparing Examples 4 to 6, Example 6 showed the most excellent purification effect in purifying the water quality of the fish pond, and also had the highest efficiency, so Example 6 is determined to be the best example. EXAMPLES

[0082] Example 7 is based on Example 6, and adds a method of cultivating earthworms in the rice field 3 in step S4. Seedlings of Pheretima, Metaphire guillelmi, and Pheretima pectinifera are introduced into the rice field 3 at a weight ratio of 8:1:1, and the introduction amount is 2 kg / ridge (1 ridge = approximately 667 m). 2 )

[0083] Cultivating earthworms in rice paddies not only breaks down organic matter and provides the nutrients needed for rice cultivation, but the earthworms can also be reused as feed for fish in fish ponds. EXAMPLES

[0084] In Example 8, compared to Example 6, in the earthworm cultivation in the rice field 3 in step S4, seedlings of Pheretima, Metaphire guillelmi, and Pheretima pectinifera are introduced into the rice field 3 in a weight ratio of 8:1:1, with an input amount of 2.5 kg / m2 (1 m2 = approximately 667 m2). By cultivating earthworms in the rice field using this method, organic matter can be decomposed to provide nutrients necessary for rice cultivation, and the earthworms can be reused as feed for fish in the fish pond. EXAMPLES

[0085] In Example 9, compared to Example 6, in the earthworm cultivation in the rice field 3 in step S4, seedlings of Pheretima, Metaphire guillelmi, and Pheretima pectinifera are introduced into the rice field 3 in a weight ratio of 8:1:1, with an input amount of 3 kg / ridge. By cultivating earthworms in the rice field using this method, organic matter can be decomposed to provide nutrients necessary for rice cultivation, and the earthworms can be reused as feed for fish in the fish pond. As a result of comparing Examples 7 to 9, Example 9 had the highest production volume of earthworm culture and was determined to be the most suitable example. EXAMPLES

[0086] Example 10 is an improvement over Example 9 in that it uses rice straw after harvesting. In this example, rice straw after harvesting is dried in the sun every year until the moisture content is 3%. The dried straw is then put into a grinder and crushed to obtain straw pieces 5 cm long. These straw pieces are returned to the rice paddy and used as food for earthworms. The crushed rice straw is used as food for earthworm cultivation, creating an eco-cycle. EXAMPLES

[0087] Example 11 is an improvement over Example 9 in that it uses rice straw after harvest. In this example, rice straw after harvest is dried in the sun every year until the moisture content is 4%. The dried straw is then put into a grinder and crushed to obtain straw pieces 8 cm long. These straw pieces are returned to the rice paddy and used as food for earthworms. EXAMPLES

[0088] Example 12 is an improvement over Example 9 in that it uses rice straw after harvest. In this example, rice straw after harvest is dried in the sun every year until the moisture content is 5%. The dried straw is then put into a grinder and crushed to obtain straw pieces 10 cm long. These straw pieces are returned to the rice paddy and used as food for earthworms.

[0089] As a result of comparing Examples 10 to 12, Example 10 was determined to be the most suitable example since it had the best crushing effect and was mixed well with the muddy soil of the rice paddy field.
