Description

Water body purification system of aquaculture pond

Technical Field

The utility model relates to an aquaculture equipment technical field, in particular to water clean system in aquaculture pond.

Background

In common words, "fish culture is performed first, water is cultured well," fish is cultured well in good water ", water quality is very important for fish culture, and the existence of ammonia nitrogen in the culture water is an invisible killer for aquatic animals. The ammonia nitrogen mainly comes from the decomposition of fertilizers, feeds, excrement, bottom organic matters and bacteria, and the proportion of the ammonia nitrogen is increased due to the increase of the pH value, the temperature and the salinity of external pollution. Causing excessive organic matters in the water body, low transparency, aging water quality, higher pH value of the water body and oxygen deficiency of bottom water.

In addition, oxygen is one of the essential conditions for fish to live. The breathing of aquatic animals consumes oxygen, and the decomposition of organic matters and bottom mud in water also consumes a large amount of oxygen, so that the oxygen content of the water body in the pond is reduced, particularly the water body at the bottom layer of the pond.

Most of the existing oxygenation modes adopt a running water machine to oxygenate, namely, the running water machine drives an impeller to rotate through a motor, and then water in a pond is stirred and beaten, so that air above the pond is partially dissolved in the water in contact with the water, oxygenation to the water is realized, but the water only can reach the upper layer is oxygenated, and oxygenation to the lower layer cannot be realized. And part of the oxygen-enriched air is pumped to the bottom of the pond through a pipeline and an oxygen increasing machine, so that the oxygen increasing of the lower water body is realized. In the water body purification and oxygenation mode, residues of organic matters still exist in the water body, so that the water body has more impurities.

In the method for purifying the water body of the aquaculture pond disclosed in the chinese patent CN200610059750.1, the water body is pumped into the purification tank by a water pump through a water pump, suspended organic matters in the aquaculture wastewater are separated by utilizing the shallow layer precipitation principle, and the nitrogen removal, detoxification, oxygen supplementation, algae inhibition and bacteria inhibition are performed by utilizing the thin water layer natural photochemical catalytic oxidation principle, so that the purification efficiency is low, and substances in the water body beneficial to plant growth are not fully utilized, which does not meet the ecological requirements.

Referring to fig. 7 and 8, specifically, the first purifying tank 301, the second purifying tank 302 and the third purifying tank 303 are provided with drain outlets at the bottoms thereof, the drain outlets are provided with plungers 33, the plungers 33 are used for blocking the drain outlets, that is, when the drain outlets are not needed, the plungers 33 are inserted into the drain outlets, and when the drain outlets are needed, the plungers 33 are pulled out, so that the purifying tanks 31 are communicated with the drain pipes 39. A sewage draining pipeline 39 is connected below the sewage draining port. In the process of purifying the water body in the purifying tank 31, which is also the process of precipitating impurities in the water body, the impurities are required to be discharged after being precipitated to a certain thickness, so that drain outlets are arranged at the bottoms of the first purifying tank 301, the second purifying tank 302 and the third purifying tank 303. Preferably, the drain outlet is disposed in the corresponding purification tank 306 of the purification tank 31. In order to prevent the blockage of the sewage pipeline 39 and facilitate the cleaning after the blockage, a sand well 310 is connected in series in the middle of the sewage pipeline 39.

In the above, the number of the partitions 304 in the purge tank 31 can be increased as appropriate, that is, the number of the purge tanks 31 can be increased as appropriate.

The utility model discloses in, transversely set up first pipeline 21 through the bottom in the pond 1 of aquaculture aquatic products, first pipeline 21 is connected with purifying groove 31 through second pipeline 23 and third pipeline 29, and first pipeline 21 is good at second pipeline 23 far away, be connected with first aeration pipe 41 on second pipeline 23, utilize pneumatic pump 26 to go into high-pressure gas toward the inside pump of first aeration pipe 41, and explode inside second pipeline 23 from miniature aeration hole, because the water pressure of first aeration pipe 41 below is greater than the water pressure of top, and first pipeline 21 is good at second pipeline 23 far away, and the weight of atmospheric pressure is lighter than the water, therefore, the water inside and in first aeration pipe 41 top of second pipeline 23 is exerted pressure upwards by atmospheric pressure, realize the promotion to the water, and then discharge from third pipeline 29 and get into purifying groove 31. Wherein, when the air pressure is used for lifting the water body, the air is mixed with the water body, so that the oxygen content of the water body is increased, and the purification efficiency of the water body in the purification tank 31 is improved; the inside of the purifying tank 31 is partitioned into a purifying tank 306 and a water passing tank 305 by a partition 304, and the partition 304 is spaced from the bottom of the purifying tank 31, a plurality of purifying tanks 31 are connected end to end, and the water passing tank 305 of the purifying tank 31 is communicated at the upper end with the purifying tank 306 of the adjacent purifying tank 31, so that the water passing through the inside of the purifying tank 31 flows in a wave shape, and the path of the water passing through the inside of the purifying tank 31 is maximized, that is, the purifying time is increased; at the inside vegetation adsorbed layer 35 that is provided with of purification groove 31, substances such as ammonia nitrogen in the vegetation adsorbed layer 35 can the absorption water for further purification of water, and substances such as ammonia nitrogen become vegetation nutritive material, promote the vegetation to grow, can also be used as the food of the aquatic products in the pond 1 after the vegetation grows, consequently form ecological cycle.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
