Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and particularly relates to a tail water treatment system for the breeding of spiny breasted frogs. Background Art

[0002] The breeding of spiny breasted frogs requires high water quality, and clean and clear mountain spring water needs to be used. As an amphibian, spiny breasted frogs breathe oxygen in the air with their lungs and do not consume dissolved oxygen in the water body. During the breeding process, live feeds such as yellow mealworms are mainly fed. The residual baits have little pollution to the water body in a short time, and the excreta of spiny breasted frogs become the main pollution source. Therefore, the tail water of spiny breasted frog breeding has the characteristics different from that of fish breeding tail water, such as high dissolved oxygen, so additional oxygenation is not required for tail water treatment; low water temperature and low microbial decomposition efficiency; small water flow rate, etc.

[0003] At present, there is a lack of a special tail water treatment system designed for the breeding of spiny breasted frogs in the market. Most farms either lack effective treatment measures or directly apply the tail water treatment system of fish pond breeding, resulting in poor treatment effects. The tail water is difficult to meet the discharge standards and cannot be effectively recycled, and it is only used as a decoration to cope with environmental protection inspections. Therefore, it is particularly urgent to develop a set of tail water treatment system suitable for the breeding characteristics of spiny breasted frogs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tail water treatment system for the breeding of spiny breasted frogs, which can effectively remove pollutants in the breeding tail water, purify the water quality, achieve the up-to-standard discharge or recycling of the tail water, and promote the ecological balance of the farm through scientific and reasonable layout and treatment process flow.

[0019] The following will further explain and illustrate the present utility model in conjunction with the drawings of the specification, so as to be better understood by those skilled in the art.

[0020] Example 1

[0021] As Figure 1 shown, a tail water treatment system for breeding of Paa spinosa includes a sedimentation tank 1, a filtration tank 2, a microbial purification tank 3, an aquatic organism purification tank 4 and a return water tank 5.

[0022] At the upper part of one end of the sedimentation tank 1, there is a sedimentation inlet, and the sedimentation inlet is connected to the overflow trough of the breeding pond. The breeding tail water discharged from the breeding farm is centrally collected into the sedimentation tank 1. The volume of the sedimentation tank is designed such that the hydraulic retention time is greater than 3 h, the average water depth is 1.5 m, and the length-width ratio is greater than 3:7 and less than 4:6. Omnivorous fish such as carp and crucian carp are placed in the sedimentation tank, and the fish stocking amount is 5% of the breeding amount of Paa spinosa. If there are too many fish in the sedimentation tank, they should be fished out in time. At the other end of the sedimentation tank 1, there is a sedimentation outlet connected to the filtration inlet of the filtration tank 2, and a filtration outlet is arranged at one end of the filtration tank 2 away from the filtration inlet.

[0023] The area of the filtration tank is 1 / 10 of that of the sedimentation tank, and the depth is the same. At the bottom of the sedimentation tank 1 and the filtration tank 2, there is a connected conical first sewage discharge tank 6. At the bottom end of the first sewage discharge tank 6, there is a first sewage discharge pipe 7. A fish-proof net 8 is arranged between the first sewage discharge tank 6 and the sedimentation tank 1 and the filtration tank 2. The water body flows from the upper part of the sedimentation tank 1 to the first sewage discharge tank 6, and then from the first sewage discharge tank 6 to the upper part of the filtration tank 2. At the lower part of the filtration tank 2, there is a first supporting layer 9. The first supporting layer 9 divides the filtration tank into upper and lower layers for water body circulation. Coarse sand with a particle size of 3 - 5 cm is placed above the supporting layer 9. Through the physical filtration effect of the coarse sand, particulate suspended matter is further removed, reducing the subsequent treatment pressure.

[0024] The filtration outlet of the sedimentation tank 2 is connected to the purification inlet of the microbial purification tank 3 through a pipeline, and a purification outlet is arranged at one end of the microbial purification tank 3 away from the purification inlet. At the bottom of the microbial purification tank 3, there is a conical second sewage discharge tank 10. At the bottom end of the second sewage discharge tank 10, there is a second sewage discharge pipe 11. At the lower part of the microbial purification tank 3, there is a second supporting layer 12. The second supporting layer 12 divides the microbial purification tank 3 into upper and lower layers for water body circulation. The pipeline connects from the filtration outlet located at the upper part of the filtration tank 2 to the purification inlet of the microbial tank 3 located below the second supporting layer 12. Volcanic stones are placed above the second supporting layer 12. The filling amount of volcanic stones is 1 m for every 500 kg of Paa spinosa bred. 3 Volcanic stones, the thickness of the volcanic stone filler does not exceed 3 m, and the volume of a single microbial purification tank does not exceed 3 cubic meters. The water flows through the volcanic stone filtration tank, and the porous structure of the volcanic stones can effectively adsorb and decompose pollutants such as water-soluble organic matter, ammonia nitrogen, and phosphorus, improving the water quality.

[0025] The purification outlet is connected to the inlet of the aquatic organism purification pond 4 through a pipeline, and the other end of the aquatic organism purification pond 4 is provided with an outlet which is connected to the return water pond 5 through a pipeline. The depth of the aquatic organism purification pond is 20 CM, and the residence time of the water body is controlled for 1 h. A large number of calamus are planted in the pond, which not only serves as a shade plant source for the farm of Paa spinosa, but also can absorb nutrients such as nitrates and phosphates after aerobic decomposition through the plant roots to further purify the water quality. When the calamus grows vigorously, transplant it in a timely manner, which can not only reduce the content of water body nutrient salts, but also provide shade materials for the farm.

[0026] Among them, the residence time of the water body in each treatment pond is controlled by changing the pumping flow of the water pump set on the pipeline connecting between the treatment ponds at all levels. The water flowing into the recovery pond 5 after the above multi-stage treatment reaches or exceeds the discharge standard, or is recycled after disinfection. The area can be large or small, depending on local conditions. For example, it is convenient to lift water and disinfect for recycling.

[0027] The tail water treatment system for the farm of Paa spinosa of the present invention effectively solves the current problem of tail water treatment for the farm of Paa spinosa through scientific and reasonable layout and treatment technology, realizes the effective purification and recycling of the tail water, and has important significance for promoting the sustainable development of the Paa spinosa breeding industry.
