Along with the rapid development of aquaculture, aquaculture wastewater treatment has gradually attracted attention. In aquaculture wastewater treatment, disc diffuser, as an important treatment equipment, plays an important role in helping to improve the aquaculture environment water quality and sustainable development. Aquaculture wastewater is rich in organic matter and nutrients such as nitrogen and phosphorus, and if it is directly discharged into the water body, it is easy to trigger eutrophication and ecological imbalance of the water body. The disc diffuser accelerates the biodegradation process by injecting air into the wastewater to form bubbles, which promotes the contact of oxygen with the organic matter and microorganisms in the wastewater. This helps to reduce the amount of organic matter and pollutants such as nitrogen and phosphorus in the wastewater, reducing the pollution pressure on the water body.
In aquaculture wastewater treatment, the disc diffuser can provide sufficient oxygen for the microorganisms in the wastewater and promote the reproduction and growth of aerobic bacteria, thus improving the biodegradation efficiency of the wastewater. Secondly, the air bubbles of the disc diffuser can form an upward flow in the wastewater, promoting the mixing and circulation of wastewater, avoiding the production of stagnant water areas in the wastewater, and facilitating the uniform distribution of pollutants in the wastewater.
However, when the disc diffuser is applied to aquaculture wastewater treatment, some problems need to be paid attention to. First of all, according to the size of the aquaculture pond and the characteristics of the wastewater to reasonably design the arrangement and number of disc diffusers, to ensure the uniform distribution of oxygen. Secondly, the size and frequency of the bubbles need to be controlled during operation to avoid the suspended matter in the wastewater being violently stirred and affecting the water quality. In addition, regular maintenance can ensure the normal operation and service life of the disc diffuser.
As a key equipment for aquaculture wastewater treatment, disc diffuser plays an important role in improving the aquaculture environment and reducing the discharge of pollutants. Through the scientific and reasonable use of disc diffuser, it can effectively improve the efficiency of aquaculture wastewater treatment, reduce environmental risks and promote the sustainable development of aquaculture industry.
