Process and mothod of aquaculture Nitrogen and organic loadingwastewater Removal

摘要

The present invention relates to an aquaculture nitrogen removal (ANR) system which newly utilizes a carbon source for denitrifying a land fish farm and manages organic materials and nitrogen in waste water of the fish farm by accumulating nitrifying microorganisms at a high concentration in order to express optimal nitrification. A denitrifying tank for hydrolyzing and nitrifying organic materials in culturing water, which is a reactive tank for removing organic materials and nitrogen generated in the land fish farm, is connected with a nitrifying tank which can accumulate nitrifying microorganisms at a high concentration through a pipe. Particulate and dissolved organic materials in fed water are hydrolyzed in order to be utilized as a carbon source for nitrification, so that the organic materials can be effectively removed. The organic materials are preliminarily removed in subsequent nitrification, so that a low carbon/nitrogen ratio (C/N ratio) is maintained in the nitrifying tank. Accordingly, nitrifying microorganisms can be accumulated at a high concentration, and the ANR system can autonomously and biologically remove nitrogen without injection of an external carbon source.
