らがその経営や振興に大きな負担となっている。BACKGROUND OF THE INVENTION In the livestock industry, there is a problem that the location is being displaced to a remote place such as a mountain area due to a problem such as a bad smell, a problem of treatment of livestock effluent, and a management by liberalization of importation of livestock products. There are problems such as changes in the environment, etc., which are a great burden on management and promotion.

l) is contained in high concentration, and the treated water obtained by subjecting it to water treatment for BOD reduction or the like has a salt-containing composition close to brackish water in seawater or a mixed region of seawater and freshwater. In other words, it meets the conditions necessary for the growth of marine and brackish seafood.

類の養殖を行なうようにした養殖方法を提供する。For this purpose, according to the present invention, livestock wastewater is guided to a water treatment apparatus mainly for biological treatment to purify the wastewater, and the purified water from the water treatment apparatus is treated. The present invention provides a cultivation method in which effluent water is allowed to flow into a culture pond and fish and shellfish are cultured in the culture pond.

ストを掛けることなく行なえるということである。[0006] As described above, by cultivating fish and shellfishes using livestock wastewater treatment water in conjunction with livestock, costs associated with livestock wastewater treatment can be absorbed, and overall economic efficiency can be improved. What is particularly important here is that the effluent from livestock sewage meets the conditions necessary for the growth of marine and brackish seafood, and therefore the cultivation of more economical marine and brackish seafood has been promoted in the mountains. The department can do this without any extra costs.

っている。[0007] It is also important to provide conditions that facilitate advanced treatment of livestock effluents, since the costs associated with livestock effluent treatment can be absorbed. In other words, the livestock industry is forced to seek a location in the mountainous area as described above, but there are also conditions in the mountainous area where easy processing such as discharging water to vacant land can be adopted. Water pollution near the water source is likely to have a wide range of effects, and it is particularly important to promote the advanced treatment of wastewater by providing conditions that facilitate advanced treatment.
【０００８】養殖対象の魚介類としては、例えば汽水を

養殖例が見られる魚介類ならば何れも可能である。[0008] As the fish and shellfish to be cultured, for example, clams that prefer brackish water, and as the seafood, any fish and shellfish, such as sea bream and hamachi, which have already been seen in many farming cases can be used.

It is also possible to circulate. Recycling water in this way can, in part, improve the effective use of water resources and, in part, increase the salt concentration, and obtain more suitable water for aquaculture of seafood. it can.

理装置を用いる。In the present invention, the purification treatment of livestock wastewater is also an important factor. In this purification treatment, biological treatment is mainly used to prevent contamination of the treated water with harmful chemical substances and the like. It is important in that, for example, a biological treatment such as an activated sludge method or a methane fermentation method which is already used in the treatment of swine wastewater is also possible, but preferably, a BOD of about several to several tens ppm is preferred. A water treatment apparatus that stably enables advanced treatment as described above, and that enables easy treatment with a small amount of sludge and the like.

In order from the upstream, a sedimentation block for putrefaction treatment, a first anaerobic condition block for filling with a filter material for biofilm formation and treating under anaerobic conditions, and a filter material formed by adhering a polysaccharide to a porous material are preferably filled. A first aerobic condition block,
A second anaerobic condition block provided with an adsorbent layer filled with an adsorbent capable of adsorbing ammonia nitrogen and providing an assimilate layer filled with bacterial assimilates in a continuous state in the assimilatory layer, and an anaerobic condition, and A porous material is filled with a filter medium formed by adhering a polysaccharide, and a second aerobic condition block which is aerobic is continuously provided.

に硝酸態に変えられる。Each block in this water treatment apparatus functions as follows. That is, in the sedimentation block, large suspended matter is settled and putrefaction treatment is performed, and in the first anaerobic condition block, biodegradation by an anaerobic bacterium having a high decomposition treatment ability such as a BOD component under a high load condition is performed. Processing is performed. In the first aerobic condition block,
The aerobic bacteria fixed on the filter medium decompose the BOD component and the like with high efficiency and supply sufficient dissolved oxygen, and the dissolved oxygen sufficiently converts the nitrogen content in the water to be treated into a nitrate state.

クトンの発生などを防ぐ上で大切なことである。From these, a denitrification treatment is performed in a second anaerobic condition block. This denitrification treatment is described in Japanese Patent Application No. 4-29.
This method is based on the denitrification method previously proposed as No. 6533, and is different from the conventional method in which nitrate nitrogen in water is simply removed as nitrogen gas by denitrifying bacteria. This method incorporates a process of converting ammonia nitrogen into highly toxic ammonia and removing this ammonia nitrogen by adsorption with an adsorbent.As a result, multiple types of coexisting biological treatments can be used simultaneously and compared. The feature is that high denitrification treatment can be performed with a simple and simple equipment structure. It is important to sufficiently remove nitrogen, which is a eutrophic component, in order to prevent the occurrence of excessive plankton in a culture pond.

となる。[0014] Finally, in the second aerobic condition block, the same treatment as in the first aerobic condition block is performed, and the continuous combination of the above treatments is combined with the supply of microorganisms to the above-mentioned soil, so that high-load wastewater is discharged. More advanced processing becomes possible.
【００１５】また、このような水処理装置については、

It is more preferable that a storage section for storing soil in which microorganisms are established is connected to the sedimentation block and that the storage section supply the soil to the sedimentation block.

The microorganisms are supplied to each biological treatment block. And as a result,
Biological treatment can efficiently function even for high-load wastewater. For example, even for livestock wastewater with a high load such as a BOD of several hundred to several hundreds of ppm, the BOD is reduced to about several ppm. Such advanced processing can be performed.

For example, a soil containing a large amount of anaerobic bacteria such as paddy soil is preferable. Further, if the storage part of the soil is used also for removing the offensive odor in the sedimentation block, the design becomes more rational. That is, the storage part is provided in the middle of the exhaust path of the sedimentation block, and the soil to be stored therein is mixed with a material having a large deodorizing power, such as fir galacton, which is carbide of rice hulls. Try to remove the bad smell of the block.
