RAS system by advanced Sea water treatment for fish preserve and aquaculture of high density in inner-city on land based

摘要

The present invention relates to an onshore inner-city advanced circulation filtering apparatus for use in high-density aquaculture. According to the present invention: a filtration is configured to have four processes; introduced water is caused to move at fast flow rates by using a circulation pump; nitrifying bacteria are attached to a biological membrane having large pores and propagated thereon, while separation of the bacteria from the membrane is prevented; by inducing nitrification in fluidized dual media, the treatment water, denitrified via ion transfer in an anoxic chamber, is treated to a fluidized support by means of advanced treatments in an aerobic chamber; and the advanced treatment is completed by aeration and using a liquid organic catalytic agent. Accordingly, the present invention provides a high-efficiency modular filtering apparatus, which resolves the problem associated with water quality control in the conventional regular aquaculture; due to the space-efficient compact size thereof, can be installed without being limited by the size of installation space; and provides an extremely convenient water quality control, and thus the present invention serves to facilitate onshore aquaculture in inner cities and the like.
