MBBR (Moving Bed Biofilm Reactor) is a disruptive technology that has achieved significant success in the aquaculture industry.
1. Basic principles of MBBR technology
MBBR technology is based on the principle of biofilm reaction, and its core principles include the following key points:
① Carrier Materials: The plastic packing or filter media used in MBBR systems provides a large amount of surface area, creating an ideal environment for microbial growth and biofilm attachment.
② Microbial attachment: Microorganisms such as bacteria, algae and other organisms attach to the surface of the carrier to form biofilms. These microorganisms degrade and decompose organic waste.
③ Suspended bed system: The carrier exists in the water in a suspended manner. Through free movement and fluidity, it ensures a high degree of contact between wastewater and microorganisms, improving wastewater treatment efficiency.
④ Oxygen supply: The MBBR system provides oxygen through a gas supply system to meet the oxygen demand required by microorganisms to degrade waste.
2. MBBR working mechanism
The working mechanism of MBBR technology is the key to its success. The following are the basic working steps of the MBBR system:
① Wastewater enters the reactor: The aquaculture wastewater is first introduced into the MBBR reactor, which contains a bioreactor unit filled with carrier material.
② Microbial attachment: In the reactor, microorganisms begin to attach to the carrier material, forming a biofilm.
③ Waste Degradation: Microorganisms in the biofilm begin to degrade the organic matter and nitrogen compounds in the wastewater, converting them into more stable and less polluting compounds.
④ Oxygen supply: Through the gas supply system, the MBBR system maintains oxygen supply, ensuring that microorganisms have enough oxygen when degrading waste.
⑤ Clean water discharge: Treated water is discharged from the reactor and usually has a higher water quality standard and is suitable for recirculation or discharge to the environment.
3. How MBBR technology improves breeding efficiency
The reason why MBBR technology is considered the key to improving farming efficiency is that it has a positive impact in multiple aspects:
① Water quality improvement: The MBBR system can efficiently remove organic waste and nitrogen compounds from wastewater, ensuring that the water quality meets the needs of farmed species.
② Increased breeding density: Since the MBBR system takes up less space, it allows more organisms to be cultured in a limited area, thereby increasing production.
③ Recycling of water resources: The MBBR system can recycle treated water, reducing the demand for fresh water and reducing the waste of water resources.
④ Control and monitoring: The MBBR system is highly monitorable and controllable, allowing farmers to better manage and adjust the breeding environment to improve production efficiency.
Overall, MBBR technology, with its unique principles and working mechanisms, provides an efficient, sustainable and environmentally friendly water treatment solution for the aquaculture industry, thereby improving breeding efficiency and is expected to continue to be used in the aquaculture field in the future. play a key role.
