A method for improving water treatment efficiency in energy-efficient culture ponds

Abstract

The invention relates to a method for improving the water treatment efficiency of an energy efficiency culture pool. A circulating culture system comprises a culture pool zone for culturing eating fishes and a purifying pool zone for culturing filter-feeding aquatic animals; a drainage channel of the culture pool zone is enclosed by a purse net to form an independent zone, and floating aquatic plants are arranged in the independent zone to form an anaerobic zone; the purifying pool zone is enclosed by a purse net to form two independent zones, and according to the flow direction of water, only filter-feeding shellfishes are arranged in a first zone, only floating aquatic plants are arranged in a second area, and the rest water surface is open and a small number of filter-feeding fishes are put therein; in the purifying pool, an aerobic zone, an anaerobic zone and an aerobic zone are sequentially formed; the circulating culture system provides a water-lifting circulating power by virtue of a water impeller arranged at the jointing edge of the culture pool and the purifying pool; the water impeller is closed once every three days, and the closing time is 24 hours, so that the staying time of water in the purifying zone is prolonged; when the water impeller is closed, standby emergency aeration and oxygenation is started in the culture zone.

Description

technical field [0001] The invention relates to an energy-efficient aquaculture pond, in particular to a method for improving the water treatment efficiency of an energy-efficiency aquaculture pond, and belongs to the technical field of energy-efficiency aquaculture pond water treatment. Background technique [0002] The energy-efficiency pool mainly adopts a separate culture method to separate the filter-feeding fish from the feeding fish, so as to avoid the problem of difficulty in catching. Moreover, part of the water surface of the energy-efficiency pool is a purification area, and part of the water surface is a breeding cement pool, so that the breeding The system is more efficient and saves water. [0003] Whether the energy-efficiency pool can play an efficient and water-saving role depends on whether the purification zone can effectively remove nitrogen and phosphorus from the aquaculture discharge water in a timely manner to achieve water recycling. In the past des...
