According to the utility model, a strong bacterial bed is constructed at the bottom of the circulating water culture pond, so that organic matters such as fish manure and residual bait which are continuously produced can be efficiently decomposed, digested and absorbed, and a benign ecological balance is achieved, so that the stability of water quality is ensured.
Description
Technical Field
The utility model relates to the technical field of culture ponds, in particular to a device for promoting the diversification of the water body habitat of a circulating water culture pond.
Background
In the industrial circulating water aquaculture facilities of the current mainstream, an aquaculture pond is generally designed to be round, the bottom is in an inverted conical shape, and a drainage system is arranged at the tip of the conical shape, so that the sewage disposal design has the advantages that water in the fish pond can be pushed by a water pump to move along a circular track, and solid pollutants such as fish dung and residual bait in the water body are concentrated towards the center of the bottom; when the drainage system is started, most pollutants can be carried away by less water due to the limiting effect of the conical bottom, so that the aim of economical pollution discharge is fulfilled.
However, although the design can timely clear out fish manure and residual baits, the design needs to be additionally supported by a sewage treatment system, and high-concentration sewage needs to be discharged regularly, so that a certain environmental protection risk exists.
Disclosure of Invention
The utility model aims to solve the defects of the prior art and provide a method for constructing a habitat which is beneficial to the activity of aerobic microorganisms at the bottom of a culture pond, and promoting and enhancing the digestion effect of the culture pond on organic matters so as to achieve the aims of high efficiency, environmental protection and tail water emission reduction.
The utility model is realized by the following technology:
a device for facilitating diversification of a water habitat of a recirculating aquaculture pond, comprising: the device comprises a culture pond, an inclined hole plate filter bed, a circulating water pump and an aeration disc.
The inclined hole plate filter bed is arranged at the bottom of the culture pond, and the thickness is preferably between 10 cm and 20 cm; the inclined hole plate filter bed is preferably made of one or more materials selected from sponge, wet curtain paper, coconut shell and palm, and the loose material has large surface area and is favorable for the adhesion and growth of microorganisms.
The inclined hole plate filter bed is uniformly provided with storage holes penetrating through the inclined hole plate filter bed so as to facilitate the flow of water rich in oxygen to pass through, thereby providing continuous dissolved oxygen for microorganisms in a loose structure and ensuring that aerobic microorganism flora always stays in advantage; the aperture of the containing hole is 1-2cm, and forms an included angle of 5-45 degrees with the vertical direction, so that a special three-dimensional structure is formed, the precipitated fish manure and residual bait can be divided into a plurality of small units and are enclosed in a microorganism-rich micro-habitat, and therefore the decomposing and absorbing efficiency is greatly improved.
An aeration disc is arranged in the culture pond and is arranged above the inclined hole plate filter bed, so that oxygen is quickly dissolved into the water body, and the oxygen content of the water body is increased;
the circulating water pump is arranged in the culture pond, so that water at the bottom of the culture pond can be conveyed to the upper part of the culture pond and sprayed out at a position higher than the horizontal plane of the culture pond, and the water falls back to the culture pond, thereby promoting the water to flow circularly all the time;
the flowing water body rich in dissolved oxygen is a necessary environment for the inclined-hole plate filter bed to run well, and a large amount of small molecules (decomposition effect of bacteria on organic matters) such as ammonia nitrogen generated locally are transferred in time while the dissolved oxygen is provided for the aerobic microbial flora cultivated on the inclined-hole plate filter bed, and are uniformly dispersed into the culture water body along with water flow, so that the water body is quickly absorbed and utilized by bacteria, microalgae, plants and the like.
The beneficial effects of the utility model are as follows: by constructing a strong bacterial bed at the bottom of the circulating water culture pond, organic matters such as fish manure, residual bait and the like which are continuously produced can be efficiently decomposed, digested and absorbed, and benign ecological balance is achieved, so that the stability of water quality is ensured.
