Abstract

PROBLEM TO BE SOLVED: To provide the subject system designed to obviate such problems involved in conventional treatment systems as the mass exchange of raising water and environmental change due to e.g. cleaning a filter tank. SOLUTION: This culture water treatment system is such one as to make use of an ozone froth cyclone treatment, a fluidized tank treatment of denitrified simple elements, and an osmosis filtration with automatic cleaning function.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to aquaculture water treatment technology.

[0002]

2. Description of the Related Art Conventionally, there is an apparatus for treating cultured water by performing biological filtration after ozone treatment.

[0003]

In the conventional treatment system, the accumulated nitrate and turbid components must be replaced with water and the filter medium must be washed, and the cost of the environment adversely affects the living body. There was a problem.

[0004] It is an object of the present invention to provide a culture water treatment system which enables non-replacement water and no maintenance and can maintain a stable environment.

[0005]

In order to achieve the above object,
The ozone-mixed air is converted into fine bubbles (using an ejector, mixer, etc.) to form a cyclone flow, and solids are settled to promote sedimentation. The ozone foam reactant is continuously discharged as a concentrated foam outside the system.

At the same time, the oxygen is efficiently dissolved by the ejector, and at the same time, the spraying force is used to flow the simple substance to efficiently perform the biological treatment, and the simple substance is treated with a hydrophilic urethane sponge (cellulose foam, polyvinyl, The use of several mm square to several cm square allows anaerobic treatment to proceed inside the aerobic treatment alone on the surface, making it possible to decompose nitrate, which is a concentrate after biological treatment.

The use of the contact oxidation treatment and the osmosis filtration together with an automatic cleaning mechanism using an air lift makes it possible to finish the treated water to a higher degree and to minimize the treatment cost.

The desired processing level can be achieved by an arbitrary combination of the above items.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, (1) an ozone-mixed air is finely introduced by an ejector or a static mixer, etc., and is introduced into a cyclone flow. A heavy solid content is formed at a lower portion by centrifugal force. The components are continuously discharged to the top as concentrated foam.

The oxygen is supplied by the ejector of (2), and the living body is made to be in a uniform flow state by the jet flow, so that the aerobic treatment is efficiently performed on the surface of the single body and the anaerobic treatment is performed inside the single body, and nitrification and denitrification are performed. Is performed in one processing tank.

(3) shows an embodiment of a final treatment mechanism having an automatic cleaning function utilizing an air lift by using both contact oxidation and permeation filtration.

FIG. 1 shows an example of processing in which the functions of the respective items are combined.

[Brief description of the drawings]

FIG. 1 is a flow sheet diagram showing the structure and flow of a system.
