Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the utility model discloses a high-efficiency low-carbon comprehensive planting and breeding system for fisheries, which is shown in figures 1-6 and comprises a breeding unit, a resource utilization and transformation unit, a planting unit and an oxygen-enriched repair unit.

The culture unit can be a culture pond or an intensive culture facility. The waste water of the culture unit is discharged and then enters a resource utilization and conversion unit which is used as a main drainage pipeline on one hand and a three-dimensional organic waste utilization and conversion facility on the other hand. This unit is down trapezoidal, the intermediate position is hung the cage and is hung and support the freshwater mussel, the bottom sets up portable collection device and breeds benthonic animals such as the ring arris snail, the function that this unit can be realized is, the freshwater mussel is through powerful filter feeding effect, settle down fast with organic waste in breeding the waste water, the deposit is in the unit bottom, it can effectively ingest and promote organic matter's degradation and reuse to breed benthonic animals such as the ring arris snail in the bottom, organic matter degradation produces nutritive salt, freshwater mussel and ring arris snail discharge ammonia, these soluble nutritive salt are along with breeding waste water entering planting unit. In the planting unit, the culture wastewater contains nutrient salts such as nitrogen and phosphorus, but most of granular substances such as organic wastes are effectively utilized in the resource utilization and conversion unit and are partially converted into soluble nitrogen and phosphorus nutrient salts which can be directly absorbed and utilized by economic crops such as rice and the like. The rice planting unit comprises 9 field blocks which are of a serial connection structure, and aims to realize longer hydraulic retention and higher nutrient salt utilization efficiency, nutrient salts in the breeding tail water are purified through absorption and utilization of plants such as rice, and finally flow into the oxygen-enriched repairing unit, the unit is a water inlet channel, the channel structure is consistent with the water outlet channel, but a mussel breeding cage is not arranged, animals such as mussels and periwinkle snails are not bred, emergent aquatic plants are planted in the middle of the water inlet channel, hygrophytes are planted in the revetments on two sides, a water pumping device is arranged on one side of the unit close to the breeding unit, on one hand, water is pumped out from the planting unit and is injected into the breeding unit, on the other hand, water dissolved oxygen is increased, and accordingly cyclic utilization and multistage utilization of resources are achieved. The breeding unit and the resource utilization and conversion unit are connected in a pipe-pulling mode through the inspection well, breeding tail water flows out of the bottom of the breeding system through the inspection well by utilizing water level difference, and the advantage that the breeding tail water flows out of the bottom is that large bottom power can be generated, and more breeding particle wastes can be taken away.

The specific operation process is as follows:

the aquaculture wastewater in the aquaculture unit is discharged into a drainage channel, the drainage channel is a resource utilization and conversion unit, the aquaculture wastewater flows in the drainage channel, organic particle wastes in the wastewater are preliminarily removed after the aquaculture wastewater is cooperatively purified by mussels, treponema annulatum and the like in the flowing process, and then the aquaculture wastewater flows into the planting unit. The planting unit is 9 paddy fields and establishes ties, breed after the waste water flows through 9 paddy fields, absorption and utilization through the paddy field, effectively got rid of the nutritive salt such as nitric acid nitrogen in the waste water of breeding, ammonia nitrogen, nitrite nitrogen and active phosphorus, thereby reach the purpose that the resource was synthesized and is recycled, go into the ditch of intaking after planting the unit outflow, oxygen boosting restores the district promptly, emergent aquatic plant and hygrophyte further absorb the utilization in the ditch, nutritive salt further gets rid of, emergent aquatic plant has certain promotion and regulatory action to promoting and stabilizing water dissolved oxygen content simultaneously, there is pumping equipment at the ditch end, go into the breed unit through lifting water and sprinkling irrigation, play the oxygenation effect, the breed waste water after being purified also flows into again and breeds unit cyclic utilization.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
