Self-cleaning large-scale culture control system utilizing immobilized microorganism water

Abstract

The invention relates to a self-cleaning large-scale culture control system utilizing immobilized microorganism water. The control system comprises a microprocessor, a nutrition source supplementing system, a self-cleaning system, an oxygenation system, an ammonia nitrogen and nitrite nitrogen monitoring system, a chemical and biochemical oxygen demand monitoring system and a controller, wherein amemory and an analog-to-digital converter are arranged in the microprocessor, wherein the microprocessor is connected with the nutrition source supplementing system, the self-cleaning system, the ammonia nitrogen and nitrite nitrogen monitoring system and the chemical and biochemical oxygen demand monitoring system respectively; the controller receives data monitored by the ammonia nitrogen and nitrite nitrogen monitoring system and the chemical and biochemical oxygen demand monitoring system, and the microprocessor decides whether to start a nutrition source input pump in the nutrition source supplementing system and a sewage pump in the sewage system or not according to the obtained data. By adopting the technical scheme, the water quality condition can be monitored in real time, the material of an immobilized filler has the capacity of reducing the ammonia nitrogen concentration in the water body, and the immobilized filler can be repeatedly used after being cleaned.

Description

Technical field [0001] The invention relates to the field of aquaculture water treatment, in particular to a self-cleaning large-scale aquaculture control system using immobilized microbial water bodies. Background technique [0002] The current treatment technology of aquaculture wastewater is mainly realized by changing water, filtering or cultivating water purification microorganisms. Water exchange is a great waste of water resources, and the discharged sewage will cause more pollution to the environment, which is not conducive to the current policies of the times. The filtering method can effectively remove the solid pollutants, but to filter out the pollutants dissolved in the water, more detailed membranes and energy consumption are required, and the cost is too high. Microbial purification technology is more suitable for the treatment of aquaculture wastewater, but the microorganisms grow and multiply and are suspended in the water body, which greatly affects the color o...
