Technical Field

The invention relates to the technical field of aquaculture, in particular to a pond runway type circulating water fish culture excrement treatment system and method.

Background

China is the first aquaculture country in the world, the total aquaculture yield in China in 2018 exceeds 5000 ten thousand tons, most (more than 50%) of aquaculture comes from pond culture, and in recent years, due to the gradual tightening of environmental protection policies, the proportion of pond culture is continuously increased by adopting the restriction of forbidden culture for part of extensive culture modes (such as reservoir culture and lake surrounding culture). But the intensive pond culture has high density and high feed coefficient, 70 to 80 percent of feed enters a water body, and residual feed and excrement of fishes and shrimps cause serious pollution to the water body, bottom mud and the like, so that the culture water body is eutrophicated. The water in the traditional pond culture mode is quite static, residual bait, fish and shrimp excrement and the like are deposited at the bottom of the pond, the water in the pond culture mode of pond circulating water flows circularly, fish and shrimp are cultured in a centralized mode, the residual bait, the fish and shrimp excrement and the like are collected in a centralized mode, the culture efficiency is improved, and the water quality is improved to a certain extent. However, there is no scientific solution for how to treat the collected residual baits, feces and other pollutants. At present, two modes are generally adopted to treat collected dirt such as residual bait, excrement and the like, and one mode is to directly discharge the collected dirt such as residual bait, excrement and the like, so that not only is the environment polluted, but also the serious waste of resources is caused (the collected dirt contains a large amount of feed); the other way is to produce fertilizer, but the problem that the collected dirt is produced into fertilizer and a large amount of manpower and material resources are needed is always troubling farmers, and the healthy, efficient and rapid development of the aquaculture industry is also limited.
