The present invention relates to an apparatus for circulating drain water in a farming water tank, which reprocesses farming water drained from the farming water tank for farming various kinds of fish to resupply reprocessed farming water to the farming water tank and, more specifically, to a multipurpose circulation chamber for recycling drain water from a farming water tank, which supplies farming water, drained from the farming water tank and flowing into a pumping chamber located at a lower side of a chamber pipe, to a water pressure adjustment chamber located at an upper side of the chamber pipe, whereas making farming water, supplied from the pumping chamber, strongly collide with farming water, stored in the water pressure adjustment chamber, thereby reasonably recycling the farming water in a manner of removing a gas constituent like carbon dioxide contained in farming water, simultaneously supplying oxygen by external air in the strong farming water collision process and then resupplying the corresponding farming water into the farming water tank; optimizing a solid constituent in farming water drained from the farming water tank for a large scale building type farming water tank which has a solid constituent collection device for water level adjustment to primarily collect the solid component within the farming water tank and a water stream generator forming a swirl type flow of farming water stored in the farming water tank, thereby preventing unnecessary abuse of farming water and reducing a final processing load of farming water; and simultaneously having a function of changing water stream states of farming water stored in the farming water tank by adjusting the water level of the water pressure adjustment chamber connected to the water stream generator. |
