Description

Fish farming oxygen supply and water quality improvement device {omitted}

The present invention relates to an oxygen supply and water quality improvement apparatus for fish cultured water, and more particularly, to remove oxygen supply, ammonia nitrogen, floating matters, and bacteria by discharging ultra-small cells into the cultured water of a fish farming tank. A supply and water quality improvement apparatus.

Under natural conditions, fish usually live freely in a good water environment of 1 to 2 water levels and at their own water temperature, survive by feeding and excreting, and in farmed fish, breathe with oxygen dissolved in water in a limited aquatic space, It grows by eating the feed fed from the outside and discharging the excreta, and the dissolved oxygen in the water is limited, and this oxygen is consumed by the respiratory action of the fish. Suspensions are generated and ammonia nitrogen, which is harmful to fish growth, is also released, resulting in contaminated farming water.

Looking at the example of the conventional fish farming, the sea cages were popular in the early days, but in recent years, the land fish farming has become popular.

In land fish farming, aquaculture tanks have been established on the ground, flow-through fisheries that keep inflow and outflow, and circulating filtered fisheries that filter and reuse used aquaculture tanks.

Water flow improves the water quality in aquaculture tanks by continuously introducing and draining new cultured water from the outside to supply oxygen, and the suspended solids and ammonia nitrogen in the culture water flow to the outside as they flow out.

 The circulating filtration method blows compressed air into the cultured water from the outside to dissolve oxygen in the water, or discharges and dissolves it in water while vaporizing the compressed oxygen in a sealed container from a specialized company. The filtered water is transferred to a sand-filled sand filtration device for filtration, and the filtered water is circulated to the aquaculture tank.Ammonia nitrogen removal is used to control supplementary water inflow and keep the input of fish at a low density. In order to delay and control, a large amount of floating water is introduced into the sand filtration system, which causes clogging in a short time. Therefore, the backwashing is frequently performed and treatment efficiency is lowered. After the filtration, the filtered water was introduced into the biological treatment chamber and subjected to biological treatment, The method of circulating aquaculture tanks by reducing monia nitrogen is adopted. This treatment method also involves sterilization of fish by the excretion of fish while the cultured water stays in the culture tank, causing bacteria to multiply and damage the growth of fish. I'm using antibiotics.

As shown above, in the conventional land fish farming, the flowing water continuously inflows and outflows of fresh aquaculture in which oxygen is dissolved, thus limiting the supply of aquaculture waters, and especially in the case of groundwater, it is difficult to secure water, The contaminated water is sent to rivers and lakes as it is to contaminate the water system.In the circulating filtration system, a blower is operated to blow compressed air into the water to dissolve the oxygen in the water, or to compress the oxygen into the sealed container. Dispensing and dissolving in cultured water is expensive, and it is expensive to carry out screen filtration and biotreatment to remove suspended solids and ammonia nitrogen in the cultured water. Bacteria multiply and cause damage to fish and use antibiotics. The problem is that antibiotics remain when shipped.

In order to solve the above problems, the present invention generates ultra-micro-cells from the micro-micro-bubble generating apparatus and discharges them directly into the cultured water where fish live, saturating the dissolved oxygen level of the cultured water, while maintaining the dissolved oxygen saturated state. Oxygen discharged to contact with ammonia nitrogen to oxidize and decompose ammonia nitrogen, and suspended matters and bacteria in cultured water are separated and removed from the surface by ultra-fine foam immediately after occurrence in fish tanks. Bacteria attached to the body are also floated to the surface by the adsorption and adhesion of ultra-miniature cells, so that the use of antibiotics is suppressed and the quality of the culture tank is maintained continuously.

The smaller the diameter, the stronger the adhesion and adhesion, the more the oxygen dissolved in the water, without being released into the atmosphere, and dissolved in the water. Once the dissolved oxygen level in the water becomes saturated, it contacts the ammonia nitrogen and releases the ammonia nitrogen. It is preferable to employ a line mixer type ultra-fine foam generator having excellent oxidation / decomposition treatment, and excellent in ultra-micro-foam production.

In the present invention, the culture tank 1, the ultra-miniature foam generator 8, and the purification apparatus 12 are main apparatuses, and the apparatuses are formed by connecting the main apparatuses 1, 8, 12 to each other.

Purification The treated water is again supplied as bubble water to the ultra-fine foam generator 8 so that the cultured water of the culture tank 1 is circulated.

By discharging the super-micro foam cloth directly into the water of the culture tank to saturate the dissolved oxygen level in the water and maintaining the saturation state, the oxygen continuously discharged is directly contacted with the ammonia nitrogen and oxidized and decomposed to release the ammonia nitrogen which is harmful to fish. Removed immediately after discharge.
