る。2. Description of the Related Art So-called fish stocks for stocking captured saltwater fish as live fish and aquaculture of hatched fry are seawater in the bay (the liquid to be treated used in the following description is synonymous with seawater. Depending on the necessity of expression, it is performed by directly circulating seawater in a cage that directly uses the liquid to be treated or seawater) or an artificial fish tank on land. Of these, fish farming in fish cages is susceptible to industrial wastewater, domestic wastewater, pollution of seawater itself such as red tide, and weather, so that fish storage and aquaculture using a fish tank has been receiving attention in recent years.

が低く、海水を充分に浄化できるものではなかった。However, in such artificial fish storage and aquaculture, a small amount of seawater in a fish tank is used for excretion of saltwater fish, metabolites such as body fluids and scales, residual food, and garbage. , Because it is contaminated with impurities such as rust, a separate water purification device must be used, but the porous materials such as barley stone, ceramics and zeolite used as adsorbents in this water purification device decompose impurities. The treatment capacity for removal was low, and seawater could not be sufficiently purified.

ていた。Therefore, not only the septic tank of the water purification device needs to be backwashed frequently and the adsorbent needs to be replaced in a relatively short period of time, but also regular replacement of seawater is required. It was very expensive and time consuming. Further, in the above-mentioned water purification device, in order to secure a certain amount of treatment capacity, it is necessary to have the same volume as that of the fish tank, and it cannot be installed without a considerable space. In general, for the storage and cultivation of saltwater fish, it is necessary to manage the seawater in a fish tank within a temperature range of approximately 15 to 20 ° C, cooling in summer and heating in winter. Since the cooling device is of a motor type, it consumes a lot of power and is extremely noisy. Also, because seawater is cooled through the cooling pipe, rust occurs on the cooling pipe and other parts, and the service life of the cooling device is as short as about 2 years. It was a thing. Furthermore, in recent years, various non-exchange water aquaculture devices have been proposed, which do not require long-term exchange of seawater in a fish tank, but none of them can treat impurities sufficiently satisfactorily. The treatment of ammonia eluted from the feed into the liquid to be treated was performed only by adsorption with an adsorbent, and the decomposition treatment by microorganisms was not effectively performed. In addition, water-soluble phosphates such as sodium, potassium, and ammonium phosphates, which are harmful when accumulated, are mostly removed by the microorganisms living in the porous material of the adsorbent, but are hardly removed from the liquid to be treated. It was impossible, and it was a major factor in alienating the development of the non-exchange water culture device.

る。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water purification apparatus for decomposing impurities contained in seawater in a fish tank by using effective microorganisms. , By treating with a suspension removal device that separates other impurities that cannot be decomposed by microorganisms, and effectively removes the water-soluble phosphate in the impurities that were previously difficult to remove, using both these devices, The aim is to enable fish storage and aquaculture without changing the seawater in the fish tank for a long time.
