A system for improving water quality in flowing water pond culture

Abstract

The invention discloses a system for improving the quality of breeding water of a running water pond. The system comprises a pond body, wherein a water inlet is formed in one side of an opening of thetop of the pond body; a filter tower and a purifier are arranged on one side of the pond body; a plurality of sewage discharge holes are uniformly formed in the bottom wall of the pond body; a sewagedischarge tube is arranged on the lower part of the pond body; a plurality of water inlet holes are uniformly formed in the side, which is positioned on the pond body, of a water purifying tube; theother side of a water inlet tube is connected with a water tube in a penetrating manner; an oxygen supply tube is arranged in the water purifying tube; the top of the side, which is positioned on thepond body, of the oxygen supply tube is uniformly connected with a plurality of air spraying tubes in a penetrating manner; and the other side of the oxygen supply tube is connected with an air tube in a penetrating manner. The water purifying tube is matched with a filter tower to filter water on the bottom of the pond body, impurities in the water are removed, and the quality of the water on thebottom of the pond body is improved; and a purifier is matched with the oxygen supply tube to provide full and high-quality fresh air for the bottom of the pond body, the oxygen content of the wateris increased, and the bottom environment of the pond body is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture ponds, in particular to a system for improving the water quality of aquaculture ponds. Background technique [0002] Running water fish farming is a method of high-density fish farming in flowing water bodies. During the feeding process, fresh water is continuously injected and old water is discharged to maintain sufficient dissolved oxygen and good water quality, and then fed with nutrient-rich feed, you can Obtain a yield that is dozens of times higher than ordinary pond fish farming. The main feature of the intensive flowing water fish farming method is to maintain the balance of the water body environment throughout the breeding process, and to realize water-saving, energy-saving and efficient intensive fishery production methods with the help of effective biological, mechanical, chemical and other means and corresponding facilities . Running water fish farming generally uses mountain st...

Problems solved by technology

[0003] Running water fish farming is to raise a large number of fish in a small water body. In order to keep the water quality fresh, the water in the fish pond must be continuously flowed and exchanged, and the fish feces, residual bait and dirt must be discharged out of the pond in time. However, cold-water fish cultured in flowing water , In the process of sub-cold water fish, the feces excreted by the fish in the pond and the leftover bait cannot be discharged in time and effectively, the waste deposited in the pond is excessive, the pool water is turbid, resulting in eutrophication of the water body, easy to pollute, and the probability of fish disease is increased. Moreover, the quality of the water in the lower part of the pond is too poor, and the oxygen content in the water is low, resulting in fish not living in the lower part of the pond, and the utilization rate of the pond is greatly reduced; Scrape up the feces and sundries at the bottom, and the fish will be killed or injured. After the fish feces and sundries are mixed with water, the valve will be opened to discharge the water, feces and sundries into the Feishui ditch, which will greatly waste the scarce stream water resources. Increased farming costs and reduced profits
