Embodiment 1

[0026] A double-channel water treatment method for a seawater industrialized circulating water system. This method is based on the biofilm method of water treatment in the industrialized circulating aquaculture system commonly used at present. The mechanism of phytoremediation and the principle of harmonious symbiosis of multi-trophic marine organisms such as fish, shrimp, shellfish, algae, and ginseng form a new method of dual-channel water treatment for industrial circulating water systems.

[0027] like figure 2 , 3 , 4, the breeding facility of the method includes a breeding pond 1, a total return water pipeline 2, an electric regulating valve 3 during the day, an electric regulating valve 4 at night, a microfilter or a sand filter 5, a circulating water pump 6, a multi-stage shellfish Algae purification tank 7, multi-stage biofilm filter tank 8, ultraviolet sterilization and dissolved oxygen tank 9, total water inlet pipeline 10, sunlight greenhouse 11 and vortex separa...

Abstract

The invention relates to a dual-channel water processing method of a factory-like circulating sea water system and belongs to the technical field of fishery facilities and equipment. According to the invention, on the basis of a currently commonly-adopted bio-film process water treating method adopted by a factory-like circulating water aquaculture system, a cowry and algae ecological filtering channel is added in parallel. Nutrition substance in the aquaculture water body can be removed continuously and fouling can be converted to valuable sea products in the form of cowry and algae biomass and the valuable sea products can be moved outside the circulating water aquaculture system by utilizing a harmonious coexistence principle of multi-nutrition-level marine organisms such as sea fishes, shrimps, cowries, algae, sea slugs and the like, utilizing features of rapid growth and reproducible capability of large-scale seaweed and utilizing the capability of shellfishes eating residual feeds, excrement and other organic particles in the aquaculture water. The invention achieves an aim of processing aquaculture waste water at low cost and in high efficiency. Therefore, the method provided by the invention may have a good application prospect in factory-like circulating sea water aquaculture in our nation.

Description

technical field [0001] The invention belongs to the technical field of fishery facilities and equipment, and in particular relates to a double-channel water treatment method of a seawater industrialized circulating water system. Background technique [0002] Industrialized recirculating aquaculture refers to aquaculture production under fully artificial control conditions. It is an advanced industrialized aquaculture model and the only way for my country's mariculture industry to transform from an extensive aquaculture model to a modern industrialized aquaculture model. At present, in domestic and foreign industrialized recirculating aquaculture systems, the aquaculture water treatment process mainly adopts the biofilm treatment method. been noticed by people. [0003] Biofilm filtration method: it belongs to microbial repair, which uses some nitrifying bacteria in nature to absorb, degrade and transfer pollutants in aquaculture water, so as to reduce or finally eliminate r...
