The present invention relates to a water purification device of various fish farms and wastewater treatment plants. More specifically, the water quality is purified using a biological treatment device without separate aeration tanks and filtration facilities for activating microorganisms in fish farms or wastewater treatment plants. It is to be done. In particular, the microbial contact media is installed on the frame shelf, but the end of the microbial contact media is submerged in water, and the upper end of the microbial contact media is exposed to the upper surface of the surface to promote aerobic microbial propagation, thereby contaminating the pollutants of the fish farm or the water quality of the wastewater treatment plant. The present invention relates to a water purification system for a fish farm and a wastewater treatment plant, which can be purified by a treatment method.

Conventional fish farm water purification device is to install a separate artificial water plants to clean the contaminated water by itself, and to install a water wheel to increase the amount of dissolved oxygen by supplying oxygen in the process of stirring the water in the fish farm And, a number of filters were put in the fish farm water so that the remaining sludge adhered to the filter, and then the filter was washed separately to manage the water of the fish farm. However, the above methods are very insignificant to purify the water quality, so the purification of the water quality is not made, and there is a problem in that a separate purification device is installed to purify the water quality and the sediment layer in which fish dung and feed are accumulated is cleaned separately.

Therefore, in order to effectively purify the water quality of the fish farm or wastewater treatment plant, a separate water treatment device must be installed, which requires facility cost and installation space. In particular, even if a purification facility is installed, inconvenience of replacing a filter or filtering member is required. There was this.

Looking at the prior art of the prior art, the "fish farm tank purification device" of the registered utility model No. 235664 is "ultraviolet light member consisting of an inlet tube and an ultraviolet lamp connected to the body of the vessel-type device, the drain pipe of the tank Wow; A filter member comprising a filter installed to enable infinitely orbital motion by a drive roll connected to the drive motor and a connecting member and a plurality of driven rolls; An activated carbon member which is filled with activated carbon in a net of a predetermined size; A filtration member made of a plurality of bio balls in which harmful bacteria are parasitic; Dissolved oxygen device is attached to the middle of the supply pipe connected to the circulation pump to supply the cleaning member and the cleaning member and the plurality of washing tubes and nozzles for spraying the washing water to the filter of the filter member by a separate washing pump to the tank. Purification device for fish farming tank equipped with supply member 'was provided, but Utility Model No. 235664 also installed facilities such as ultraviolet member, filter member, activated carbon, filtration member, washing member, etc. as a means for purifying water in farms. In order to purify the water quality, there is a problem in that the filter member, activated carbon, filtration member and the like need to be washed and replaced from time to time. Therefore, such a water purification apparatus has a problem in that management costs are increased as time passes.

In addition, "Sewage Purification Device of Fish Farm" of Patent Publication No. 2003-74852, "Fish fences installed in rivers, seas or reservoirs, etc. in order to prevent the rearing of fish raised, and fish that are dropped in the lower portion of the fish fence A sewage collecting outlet for collecting sewage contaminated by the feed or excreta of the sewage, a sewage discharge pipe connected to a lower end of the sewage collecting outlet to discharge sewage outward, and a sewage discharged from the sewage discharge pipe up and down at a predetermined interval; It can be seen that it consists of a multi-layer purification means for purifying sewage up to a predetermined reference value while dropping the upper surface of a plurality of flow plates that are zigzagly arranged on one side and the other side, but this is also a sewage collection port at the bottom of the fish fence. To transfer the collected sewage to the purification means installed on one side through the sewage discharge pipe As a treatment system, the sewage of a fish farm is treated with a multi-stage purification means, and the purified water is supplied again. Therefore, the cleaning and management of the purification means for treating the sewage is complicated, and the water of the fish farm is not a biological treatment method. There is a problem that must be managed continuously by selecting an artificial treatment method.
