TH7574C3 - Water circulation system for aquaculture - Google Patents

Abstract

DC60 (30/03/55) invention of this Involves the development of a circulating system for aquaculture in a closed system, with a closed water recirculation system consisting of a raw water pond for sedimentation. Water storage ponds for use in culture ponds Nursery pond And the treatment pond is divided into 3 parts: sedimentation pond, filter pond and biological pond for water quality treatment. The used sea is of better quality and can be used again in the aquaculture system. And also can be more A semi-closed water circulation system that helps to maintain the nutrients in seawater in the aquaculture system in equilibrium, thus reducing costs and reducing the frequency of water change in aquaculture systems unlike circulating and treatment systems.

Claims (3)

1. The circulating system for marine aquaculture consists of a raw water tank for sedimentation. Water reservoirs for use in aquaculture systems and pumps A culture pond with porous substrate and a water quality treatment pond for reuse in the culture system. An additional characteristic is that a semi-closed water circulation system has been added, partially discharging the water from the pond. Cultured to the effluent pond Then pump the raw sea water that has been filtered by flow through the water pipes into the system. Alternative culture To adjust the balance of organic nitrogen compounds to balance and to adjust the water not turbid. 2. Water circulation system for marine aquaculture according to claim 1, where the water quality treatment pond consists of a sedimentation pond that precipitates suspended solids in wastewater. Pond filter, which serves to filter things Contamination that comes with wastewater And biological ponds with materials and microorganisms to help filter Serves to improve and heal Wastewater from raising pond for better quality, biological material used in pond It is characterized by that the sea water or the wastewater that is used from the culture pond will pass into the sedimentation pond and Filter sump to filter out contaminants attached to wastewater first. It enters the biological pond with water quality treatment 2 times, the first time increasing the oxygen content in the water and treating the water quality with bacteria, then releasing the said sea water or wastewater through the filter system with coarse sand and rocks. Artificial corals for water quality treatment are The second with a group of bacteria capable of converting nitrogen organic compounds into compounds Inorganic nitrogen The ammonia content in the water is converted to nitrite compounds, nitrate and nitrogen gas, respectively. All the water that has undergone the treatment of various parts will be placed in the well. With a bunch of sea grapes (Caulerpa racemosa) to absorb excess mineral content in order to obtain sea water of suitable quality for further use in aquaculture systems. 3. Water circulation system for marine aquaculture according to claim 1 or 2, where the material used in the pond Treatment can be selected from coarse filter, glass fiber, fine filter, coarse sand, bio-ball or rock, artificial coral or grape-bunch algae. The one The most appropriate is to use together.
