Description

Technical Field

[0001] The invention relates to the technical field of fish pond water purification, and in particular to a humanistic ecological purification system and method for improving water quality. Background Art

[0002] A fish pond is a place for fishing or raising fish, specifically the internal compartments of a fish pond or the enclosure net that encloses the fish. Generally, an ideal pond requires a large area, deep water, sufficient sunlight, unobstructed water sources, fertile water quality, and convenient transportation, so as to facilitate the growth of fish, increase production, and facilitate production management.

[0003] Water quality control for fish pond water:

[0004] 1. Add new water regularly: Generally, add new water every 7 to 10 days, and add 15 cm to 20 cm of water. When the water quality deteriorates, the water should be changed. The water color should remain grass green or brown, and the transparency should be 30 cm to 40 cm. Quicklime can also be used to adjust the water quality regularly. Generally, 15 kg to 20 kg of quicklime per mu is used every half month to dissolve the water in the whole pond and sprinkle it once.

[0005] 2. Strengthen oxygenation measures: Intensive ponds should be equipped with special aerators, which should be turned on for oxygenation between 2 and 3 pm on sunny days. In addition, they can be turned on for oxygenation when there is a danger of floating heads. Oxygenators and other related drugs can also be used for oxygenation.

[0006] 3. Use microbial preparations: Remove leftover bait and dirt in time to prevent water pollution. Microbial preparations should be used in water bodies with a lot of bottom mud to improve the bottom quality, inhibit the reproduction of various anaerobic bacteria and viruses, and prevent the occurrence of fish diseases and hypoxia.

[0007] After fish have been raised in fish ponds for too long, fish feces ferment at the bottom of the pond, resulting in an increase in the ammonia nitrogen content in the fish pond, deteriorating water quality in the fish pond, stinking, and excessive growth of plants, resulting in a decrease in oxygen content in the pond. Existing water purification methods mostly use electronic equipment to filter the water, or use chemical methods to reduce the ammonia nitrogen content in the water, which is costly. In the southern plains of my country, water resources are abundant, and almost every rice field has a fish pond. How to use the ecological cycle to purify the water used in the fish pond to save the cost of fish pond farming has become a problem. Therefore, a humanistic ecological purification system and method for improving water quality is needed. Summary of the invention

[0016] S3. When the ammonia nitrogen content in the water is monitored to be greater than 0.02 mg / L, the ecological cycle is started, the water pump in pipeline 1 is turned on, the water with excessive ammonia nitrogen is passed into the microbial purification pool, and microbial agents are added to the microbial purification pool.

[0018] S5. Turn on the pump in pipeline 3 to pass the paddy field water into the sedimentation tank, and sprinkle flocculant into the sedimentation tank. The amount of flocculant sprinkled is 100-150g / m 3 , so that the suspended matter in the paddy field water is settled to obtain settled water;

[0019] S6. Turn on the water pump of pipeline 4 to pass the sedimentation water into the aeration tank, start the ozone generator and air pump 2, and air pump 2 extracts air and ozone to mix and pass it into the mixed air pipe to disinfect the sedimentation water and replenish oxygen in the sedimentation water to obtain aerated water;

[0020] S7. Turn on the water pump in pipe five to pump the aerated water to the fish pond through pipe five. The water inlet flow rate of pipe five is consistent with the water outlet flow rate of pipe one, forming a closed loop of water purification.

[0021] Furthermore, the microbial agent is composed of the following ingredients in parts by weight: 1-3 parts of protease, 9-15 parts of activated carbon, 9-11 parts of Bacillus subtilis, 4-7 parts of lactic acid bacteria, 10-15 parts of Pleurotus eryngii residue, 4-7 parts of quicklime, and 15-20 parts of photosynthetic bacteria.

[0022] The above ingredients are all commercially available products, such as protease is "NHU-Protease 1000" from Zhejiang Xinhecheng, activated carbon is "HY-AC1000" from Hangzhou Huayuan, Bacillus subtilis is "Haida-BS01" from Qingdao Haida Biological, lactic acid bacteria is "JLB-LAB01" from Junlebao, Pleurotus eryngii residue is "JL-KOMR100" from Shandong Jinluo, quicklime is "XTC-QL100" from Hunan Xiangtan Chemical, and photosynthetic bacteria is "TB-PSB100" from Zhejiang Tianbang.

[0023] Furthermore, the flocculant is composed of the following ingredients in weight: 10-15 parts of pectin, 13-20 parts of diatomaceous earth, 13-15 parts of polyferric chloride, 7-9 parts of polyaluminum silicate, 8-13 parts of polyacrylamide, 4-7 parts of sodium carbon, and 5-10 parts of disodium ethylenediaminetetraacetate. The flocculant settles the debris and soil in the rice field.

[0024] The above ingredients are all commercially available products, such as pectin purchased from Qingdao Mingyue Seaweed Group Co., Ltd., diatomaceous earth is industrial-grade diatomaceous earth from Shanxi Yunshidai Nanomaterials Co., Ltd., polyferric chloride is PFC-I type product of Shandong Tianyi Chemical Co., Ltd., polyaluminum silicate is purchased from Henan Hengchang Environmental Protection Technology Co., Ltd., polyacrylamide is PAM-HP product of Beijing Hengju Chemical Co., Ltd., sodium carbon is industrial soda ash from Tangshan Sanyou Chemical Co., Ltd., and disodium ethylenediaminetetraacetate is EDTA-2Na product of Shanghai Kaisai Chemical Co., Ltd.

[0025] Furthermore, the fry breeding density in step S1 is 600-1200 fry / cubic meter, and the remote feeding times through the remote control are: once at 6-7 am in spring and autumn, once at 4-5 pm, once at 6-7 am in summer, once at 8-9 am in winter, and once at 2-3 pm. Too many feeding times will cause water pollution, so the above feeding method is the most effective.

[0026] Furthermore, in the step S4, for rice field cultivation of earthworms, seedlings of Pheretima circumflexus, Pheretima william, and Pheretima commissuri are placed in the rice field at a mass ratio of 8:1:1, and the amount of placement is 2-3 kg / mu. Cultivating earthworms in rice fields can not only decompose organic matter to provide necessary nutrients for rice, but also put the earthworms back into the fish pond as fish food. The ratio of each earthworm will affect the purification effect of the system. According to repeated experiments by the inventor, it is found that setting the mass ratio of Pheretima circumflexus, Pheretima william, and Pheretima commissuri seedlings to 8:1:1 is not only conducive to the growth of earthworms, but also achieves the best effect on the decomposition of microorganisms and organic matter accumulated in water.

[0027] Furthermore, the rice straw harvested each year is air-dried until the moisture content is 3-5%, and the dried straw is placed in a crusher for crushing. After crushing, straw segments are obtained, and the length of the straw segments is 5-10 cm.

[0029] The beneficial effects of the present invention are:
