Example two

Fig. 9 is a block diagram of a circulating water purifying apparatus for temporary aquaculture equipment according to an embodiment of the present invention, as shown in fig. 9, an embodiment of the present invention provides a circulating water purifying apparatus for temporary aquaculture equipment, including a nitrification tank, a refrigerator, a second circulating water pump, and a circulating water filtering apparatus for temporary aquaculture equipment according to any one of the first embodiment; the circulating water filtering device is used for conveying the treated circulating water to the nitrification box for nitrification treatment, and the second circulating water pump is used for pumping the nitrified circulating water to the refrigerator for refrigeration treatment and conveying the refrigerated circulating water to the fish tank.

Due to the design of the filter device in the first embodiment, the whole occupied area of the filter device is relatively small, and therefore the effect of circulating water purification in an effective space can be achieved better. The water purifying equipment provided by the embodiment of the utility model can realize the simultaneous feeding of water, thus greatly reducing the refrigeration energy consumption; the overall refrigeration efficiency is improved, and the water purification treatment can be better realized.

The principle of the scheme design of the embodiment of the utility model is mainly the process from oxygen consumption to anaerobism; because during the fish rearing process; the bait, the feces of the fish and the fish can continuously consume the dissolved oxygen in the water; after a period of time, if the impurities in the water are not removed, the dissolved oxygen in the water is reduced, and the living environment of the fishes becomes severe due to the overstocked excrement baits in the water; the deterioration is reflected in a decrease in the concentration of dissolved oxygen in water and accumulation of the above-mentioned impurities, which makes the environment less aesthetically pleasing. The scheme of the embodiment of the utility model improves the purification degree of the circulating water; harmful substances such as excrement, bait and the like in the circulating water are filtered through the coarse filtering device, so that on one hand, substances consuming dissolved oxygen in the water are eliminated, and on the other hand, purer circulating water quality is provided for subsequent nitrification and filtration; most harmful impurities are filtered after rough filtration, and then the circulating water entering the rough filtration is further treated by a jet module of a protein separator, because the jet module is arranged; by continuously compressing and pressurizing the air in the protein separator, on one hand, more impurities of organic protein are filtered, and on the other hand, the density of oxygen dissolved in water is greatly improved; compared with the existing scheme, the scheme of the embodiment of the application obviously improves the density of the dissolved oxygen in the water. Through the process, the process from oxygen consumption to anaerobic treatment of the circulating water is well completed, and the dissolved oxygen in the circulating water is improved. Instead of directly filling oxygen into water like the existing scheme, on one hand, the water energy and oxygen resources can be saved, on the other hand, the cost is reduced, because water can be continuously circulated, and dissolved oxygen in water is increased through jet flow, so that excessive oxygen injection is not needed by other devices. After filtering through above-mentioned two modules, can the filtering most harmful substance for follow-up health degree that enters into the circulating water in the nitrifying bacteria crowd obviously improves, makes harmful substance to the infringement of nitrifying bacteria crowd reduce, can improve purification filter effect from the one hand, also can improve this purifier's life-span greatly.
