Tailwater treatment water-recycling system for aquaculture

Abstract

The invention relates to the technical field of aquaculture, in particular to a tailwater treatment water-recycling system for aquaculture. The system comprises a primary filtering pond, a secondary filtering pond, a settling pond, a sterilization pond, a reverse osmosis pond, an ozone pond and a standing pond; a lift pump 1 is arranged outside the primary filtering pond, a lift pump 2 is arrangedoutside the secondary filtering pond, a lift pump 3 is arranged outside the settling pond, a water inlet end of the lift pump 3 is connected with a bottom water storage cavity of the secondary filtering pond, a water outlet end of the lift pump 3 is connected to a water inlet of the settling pond, the water inlet of the sterilization pond is connected to the water outlet of the settling pond, thewater inlet of the reverse osmosis pond is connected with the water outlet of the sterilization pond, the water inlet of the ozone pond is connected with the water outlet of the reverse osmosis pond,and the water inlet of the standing pond communicates with the water outlet of the ozone pond; and a water suction pump is arranged outside the standing pond, and the water inlet end of the water suction pump is arranged at the bottom of the water outlet of the standing pond. The water circulation use is achieved after the tailwater is completely treated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and specifically relates to a tail water treatment water circulation system for aquaculture. Background technique [0002] A large amount of tail water will be produced in the process of aquaculture. These tail waters contain toxic and harmful substances produced by aquaculture organisms. At present, in most cases, these tail waters are simply discharged through drainage ditch, and the discharged tail water will cause great harm to the environment. In addition, some farms will use biospheres or filters to initially filter and treat the tail water, but this method can only filter out large particles of impurities in the tail water, and cannot achieve the purpose of removing pollution; a small number of breeding The farm will use equipment such as protein separators to purify the tail water. However, at present, these tail waters are usually discharged directly after passing through several pur...
