Abstract
The invention discloses a 'fish-algae symbiotic' mariculture system capable of fixing carbon and removing nitrogen circularly, and aims to solve the problems of insufficient oxygen, temperature loss, unstable disinfection and high mortality rate of fishes caused by pathogenic microorganisms flowing into a fishpond in the conventional circulating water aquaculture technology. The upper part of a fish pond in the mariculture system is provided with an algae pond, a biochemical filter pond is positioned on the lateral part of the fish pond, the water outlet of the algae pond is connected with the water inlet of the biochemical filter pond through a water pipe, the biochemical filter pond is filled with filter materials, the water outlet of the biochemical filter pond is sequentially provided with a membrane filter device, an ultraviolet disinfection device and a micro-nano aeration device along the water flow direction, and a solid-liquid separation device and a protein separation device are sequentially arranged on the water pipe connecting the water outlet of the fish pond and the water outlet weir. The invention combines ozone and ultraviolet for disinfection, combines an algae pond and a biochemical filter pond, and leads the removal rate of COD and ammonia nitrogen pollutants of the mariculture wastewater to reach 90 percent through biochemical action, thereby realizing high purification and cyclic utilization of water.
Description
Technical Field
The invention relates to a mariculture system capable of circularly fixing carbon and removing nitrogen.
Background
The development of the circulating seawater culture system has important significance for the development of fishery in China. Firstly, the circulating mariculture can economically, safely and efficiently provide high-quality animal protein food for the people. In the culture process, the fishes are aquatic variable-temperature animals, and compared with the traditional mariculture mode, the circulating mariculture system can control energy consumption, feed conversion efficiency and product protein content by adjusting the temperature of the system. Secondly, the circulating mariculture system can make up the defect of marine fishing. The Ministry of agriculture has clearly established that near zero growth in the yield of fishing will be achieved, i.e. future growth in the yield of seafood will need to be done by means of artificial breeding. From the development condition of fishery in China, the sewage generated by the traditional breeding mode exceeds the regeneration capacity of natural resources. In offshore areas, soil salinization is formed due to the increase of traditional breeding yield, so that the land and protective coverings in the surrounding areas are degraded, and the ecological environment is out of balance.
In the existing recirculating aquaculture technology, the treated water is generally directly conveyed to a fish pond, and because the fishes have the most suitable growth temperature, the growth of the fishes in the fish pond is slow due to the unstable water temperature. In addition, in the prior art, the circulating treatment of the aquaculture water only depends on a biochemical treatment process, and the biochemical process has strict requirements on living conditions for dominant flora such as nitrobacteria in the filler, so that the water is easily affected by water body load fluctuation, nutrient salt, temperature and other changes, the circulating water treatment is unqualified, and the fish in the fish pond is poisoned and killed. In the prior art, the ultraviolet disinfection technology mainly adopted in the disinfection link can not clean and replace the ultraviolet disinfection equipment in time well, and the ultraviolet irradiation is insufficient due to long-time use, so that the disinfection effect is reduced, and the fish is caused to suffer from diseases caused by pathogenic microorganisms. In addition, most of the oxygen increasing modes adopted by the prior recirculating aquaculture technology are direct aeration oxygen increasing, the energy consumption is high, and the effect is not ideal. Therefore, the current circulating water culture technology has higher equipment cost and is not beneficial to the use of small-sized farms.
Disclosure of Invention
The invention aims to solve the problems of high fish fatality rate, high technical operation energy consumption and overhigh cost caused by insufficient oxygen, temperature loss and unstable disinfection of circulating water and the inflow of pathogenic microorganisms into a fish pond in the prior circulating water aquaculture technology, and provides a 'fish-algae symbiotic' seawater aquaculture system for circularly fixing carbon and removing nitrogen.
