Description
Technical Field
The invention relates to a closed running water pond culture system, and belongs to the technical field of pond water body purification.
Background
At present, the pollution of the river water body is more serious due to the substandard discharge of industrial wastewater and domestic sewage, and the resistance of the river culture is gradually increased. Thus, many aquaculture farms are diverted from river channels to ponds. Conventional pond culture is typically performed in relatively confined waters with certain limitations. On the one hand, the traditional pond is a relatively closed ecological system, and the self-purification capacity of the water body is relatively poor. The culture pond has various matters such as residual branches and fallen leaves of aquatic plants, residual baits, excrement and the like accumulated for a long time, and the matters cannot be degraded in time, so that organic matters such as nitrogen, phosphorus and the like and nutrient salt are excessive, the ecological system of the pond is unbalanced, and the healthy growth and the production quantity of aquatic products are influenced. On the other hand, blind drainage and water replacement in the traditional pond culture are high in cost and cause pollution to river channels. When water is changed and fresh water is introduced, residual components of pesticides and fertilizers can be introduced into the pond, so that heavy metal and organic matter in the water are polluted, and fishes are poisoned and die; the newly introduced water body may also contain new unknown elements, which are very easy to cause the stress reaction of the aquatic products, resulting in diseases, slow growth and even death. When the water body is discharged, a large amount of harmful substances are usually accumulated in the water body of the traditional pond culture system, and if the harmful substances are directly discharged, not only is the waste of water resources caused, but also the environmental pollution problem is caused.
The closed type circulating water culture is a novel culture process which is mainly used for treating culture water through technologies such as physical filtration, biological purification, denitrification oxygenation, sterilization and disinfection and the like and recycling, can effectively purify and adjust the water quality of a pond and cannot cause environmental pollution. At present, the closed type circulating water culture has the defects of high construction and operation cost, complex maintenance process and the like. For example, chinese patent CN201410585119X discloses a cultivation system for recycling sewage, which not only solves the problem of sewage treatment, but also realizes water resource recycling, but also has the problems that the system occupies a large area, and at least fifteen acres of land are required to realize the circulation of ideal water resources, and is difficult to popularize in some areas with shortage of land resources. CN208972345U proposes a pond circulating water annular groove culture system, which comprises an annular groove area, a purification area and a culture sewage treatment area on the bank, wherein the pond water body circularly flows through the annular groove area and the purification area; through the annular groove including push away water oxygenation device, annular breed unit, tank bottom micropore oxygenation device and be located the breed in the middle of the groove deposit filth collection device and breed sewage treatment discharging equipment and will breed the preliminary purification treatment of sewage and discharge the purification zone back again for rivers in the annular groove are rotatory continuously. But the process is more complex and the later maintenance is more difficult. Therefore, a closed running water pond culture system which is low in early-stage economic investment, easy to maintain, capable of recycling water resources and free of secondary pollution is urgently needed to be designed.

After a period of time, the feeding area 7 accumulates more dirt such as plant residual branches and leaves, residual bait and the like, and the dissolved oxygen in the water is reduced. At the moment, the submersible water impeller 9 is started, so that the dirt is collected and settled in the bionic aquatic weed area under the action of water power. After the sewage is settled to a certain degree, the sewage suction pump 10 is started to pump the sewage to the settling area 2. The sedimentation zone 2 can settle the dirt in the water body, and when the water level of the sedimentation zone 2 reaches the top of the flow partition wall 6, the water overflows to the filtering zone 3. The straw layer and the zeolite filter layer in the filtering area 3 further filter and intercept the dirt in the water body, and the straw is subjected to compost fermentation to decompose the intercepted dirt. The filtered water body flows into the planting pipeline 20 from the water tank of the filtering area 3, and various plants such as goldfish algae, waterweed algae, phalaris arundinacea, cattail, wild rice shoots, canna, alocasia esculenta and the like are planted in the planting pipeline 20 to remove heavy metal elements such as copper, silver, mercury, cadmium and the like in the water body. The water body after sedimentation, filtration and plant treatment flows into the water purification area 5 from the filtration area 3 through the planting pipeline 20, and the culvert pipe 13 arranged in the water purification area 5 circularly flows into the bottom of the culture area 1. After the submersible water impeller 9 and the sewage suction pump are started for 101-2 hours, the water body in the culture area 1 almost reaches the healthy culture standard, and at the moment, the submersible water impeller 9 and the sewage suction pump 10 can be closed and started.
It should be noted that the time for starting the submersible water impeller 9 and the sewage suction pump 10 can be increased or shortened according to the actual conditions of the water quantity and the cleanness degree of the water body. In addition, the number of the submersible water impeller 9 and the sewage suction pump 10 can be increased or decreased according to the size of the culture area 1, and the installation position of the submersible water impeller 9 can also be moved according to the length-width proportion of the culture area 1.
