Method and device for cascaded aquatic product comprehensive cultivation with circulating water

Abstract

The invention discloses a circulating water cascade type aquatic product comprehensive breeding method and device. The controller controls the work of the well water supply system to accurately replenish water in the greenhouse rare fish breeding area and the outdoor common fish breeding area. The better water quality realizes the precious fish breeding. Greenhouse farming, the water-sewage mixture produced in the mid-range fish breeding tanks passes through the water-sewage separator for water-sewage separation treatment and the combined use of the sewage collection channel to distribute better water sources to ordinary fish culture in the outer pond, while the sludge It is collected and processed into fertilizers. In addition, the water source of common fish ponds is ecologically purified through the water purification pond and the influent pretreatment tank is used in conjunction with the ammonia nitrogen removal water purification device to make the water source a high-quality water source. Here, it enters the comprehensive breeding device. The entire comprehensive The breeding device realizes the cascade distribution from high-quality water source to ordinary water source and the cascade breeding of indoor high-quality fish species to outdoor common fish species, and establishes a new model of cascade ecological breeding from indoor to outdoor.

Description
