Description

Technical Field

[0001] The invention patent relates to the technical field of fish farming, specifically, to resource treatment equipment for fish farming wastewater. Background Art

[0002] In the past 20 years, China's factory aquaculture industry has developed rapidly. However, while the aquaculture industry has developed rapidly, the aquaculture species have degenerated. In particular, the high-density aquaculture in the aquaculture area and the arbitrary discharge of industrial wastewater and domestic sewage have reduced the self-purification and regulation capacity of the aquaculture waters, and the aquatic environment has seriously deteriorated. Under this condition, the total effective nitrogen content in the aquaculture water body increases with the increase in the number of aquaculture. In pond aquaculture, 5-10% of the feed is not eaten by fish, and 25-30% of the feed eaten by fish is excreted in the form of feces. In terms of nitrogen input, feed accounts for 90-98%, in terms of nitrogen output, fish accounts for 20-27%, and deposited nitrogen accounts for 54-77%. In terms of phosphorus input, feed accounts for 97-98%, while deposited phosphorus accounts for 72-89% of output, and fish output accounts for only 8-24%. This means that except for a small part of the nitrogen and phosphorus content in the feed that is provided for the growth of aquaculture fish, most of them are deposited in the pond, causing waste and pollution. Excessive feeding of artificial feed, organic fertilizers and biological excrement cause a large amount of organic matter in the pond. Dissolved organic matter is a nutrient for bacteria, providing conditions for the reproduction and growth of pathogenic bacteria, increasing the possibility of disease in farmed organisms. Excessive organic matter decomposition requires a large amount of oxygen, making the pond prone to hypoxia and water quality deterioration, which directly affects the growth of farmed organisms.

The fish farming wastewater treatment device, by setting an electric slide rail, can make the sliding plate move horizontally on the electric slide rail, drive the cross bar to move, by setting an inner wall scraper, can scrape off the sludge adhered to the inner wall of the fish pond, by setting a pool bottom scraper, can scrape off the sludge and excrement at the bottom of the fish pond, by setting a water pipe and a nozzle, can spray water to clean the fish pond, thereby achieving the effect of scraping mud and cleaning the fish pond.
