Circulating water purification system for farming of Channa argus

Abstract

The invention provides a circulating water purification system for farming of Channa argus, comprising a Channa argus farming chamber, a backflushing filtering device, a collecting precipitating tank,a Hypophthalmichthys nobilis farming tank, a microbial purification deice and an ultraviolet sterilizing device. The bottom of the Channa argus farming chamber is provided with a drain pipe; the tailend of the drain pipe is communicated with the backflushing filtering device; the collecting precipitating tank is communicated with the backflushing filtering device through a backflushing blow-downpipe; the Hypophthalmichthys nobilis farming tank is communicated with the bottom of the collecting precipitating tank through a fertilizer conveying pipe; a water outlet of the backflushing filtering device is communicated with the microbial purification device; an outflow pipe of the microbial purification device is connected with a water inlet of the ultraviolet sterilizing device; a water outlet of the ultraviolet sterilizing device is connected with a water return pipe. The circulating water purification system for farming of Channa argus allows farming water to be cyclically utilized, so that mass water can be saved; the problems of Channa argus farming water recycling and waste utilization in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of snakehead cultivation, in particular to a snakehead circulating water purification cultivation system. Background technique [0002] Black fish is the common name of black snakehead [lǐ], also known as black fish, raw fish, wealth fish, snake fish, fire head fish, etc. [0003] Snakefish is ferocious by nature, has strong fecundity, and has a huge appetite. It can often eat all other fish in a certain lake or pond. Snakehead can also glide on land and migrate to other waters to find food. It can live up to 3 days away from water. Long. As early as two thousand years ago, it was listed as the top grade of insects and fish by "Shen Nong's Materia Medica" and stone honey, bee cock, beeswax, oysters, tortoise shells, mulberry ticks, sea clams, Meretrix meretrix, and carp. Snakefish is a common edible fish in China, with large body, fast growth and high economic value. Black fish has few bone spurs, high me...

Problems solved by technology

[0004] In the process of traditional snakehead farming, if the traditional extensive farming mode is still adopted, that is, natural water is used for natural farming, the waste and waste bait will be dissolved in the water, and the fish feces will sink in the bottom mud, and the breeding water will easily form rich fish. Nutritization, fish are easy to get sick and need to change the water, which will cause pollution. The polluted aquaculture water discharge to other places not only causes a lot of waste of water resources, but also produces a large amount of biological metabolites and residual waste during the aquaculture process. Residual bait, biological metabolites and residual bait cannot be well utilized, and the direct discharge of aquaculture wastewater will cause environmental pollution; factors such as aquaculture temperature and water quality cannot be effectively controlled, aquaculture lacks scientific management, and the aquaculture cycle is long. Low breeding efficiency

[0005] At present, although there is also a culture mode of snakehead circulating water purification, there are a lot of waste and waste bait residues in the polluted culture water, which cannot be discharged at one time during the purification process. It needs to be discharged through the sewage pipe with the help of filter elements or filter materials. After a period of time, the intercepted pollutants accumulate and cause the blockage of the filter element or filter material, which will reduce the water quality and water output. In this case, if it is not replaced in time, it will aggravate the water pollution and cause negative effects. No water can come out, and it is very troublesome if you change the filter element or filter material frequently
