Abstract

The invention provides an aquaculture pollution biological ecological purification and cyclic utilization system and method. The system comprises an aquaculture ecological culture pond, a biological sedimentation tank, a double-medium biological filter tank, a deep ecological purification pond, an internal circulation ecological ditch, a water purification activation tank and a disinfection tank which sequentially communicate with one another, wherein the disinfection tank communicates with the aquaculture ecological culture pond. Through physical, chemical and biological ecological purification methods, culture water is purified, so that the culture water is recycled, and residual baits, excrement, nitrogen, phosphorus, organic matters and residual fish drugs in the culture water are effectively controlled and removed; and bottom mud discharged by the biological sedimentation tank is restored and then is utilized in farmlands or orchards. Zero emission of pollutants is realized, the aquaculture pollution biological ecological purification and cyclic utilization system and method are environmentally friendly, ecological and healthy aquaculture is realized, and the aquaculture pollution biological ecological purification and cyclic utilization system and method cause little or even no pollution to the environment, and are environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a system and method for ecological purification and recycling of aquaculture polluted organisms. Background technique [0002] The self-pollution of aquaculture is one of the important reasons that limit the sustainable development of aquaculture. There are two main types of aquaculture pollutants: one is the loss of aquaculture production inputs (bait, fishery medicine, and fertilizer); Eutrophication is the main content of aquaculture emissions. With the current feeding method, 80% of the feed is eaten by fish, but only 20% of it is used for fish weight gain, and the remaining 60% is excreted as feces; the other 20% is directly discharged into the water environment as residual bait middle. The discharge of fish and residual bait has a great impact on the water environment. In current aquaculture in our country, regardless of freshwater aquaculture or marine aquaculture,...
