With the continuous growth of China's population and economy, people's quality of life is also constantly improving. Moreover, food factories have large scale, large wastewater volume, and complex composition. There are various methods for treating food wastewater. Today, the editor will take you to learn about the food wastewater treatment method - biodegradation.

Food wastewater treatment method - biodegradation:

The biodegradation method is equipped with two sedimentation tanks, which respectively hold two stages of activated sludge. The sedimentation tanks will reflux to the aeration tank, and the refluxed sludge is not in the same stage. The refluxed sludge can undergo enhanced regeneration, improving the adsorption capacity and activity of microorganisms, which is beneficial for removing organic matter from the waste.

The use of biodegradation in wastewater treatment in food factories not only removes a large amount of organic matter from water, but also effectively buffers and regulates it, and has the following characteristics:

1. The equipment does not require the installation of a primary sedimentation tank;

2. Strong anti toxic ability, able to tolerate various toxic compounds;

3. Strong degradation ability, capable of degrading COD into easily biodegradable BOD5 substances;

4. The wastewater treatment equipment is equipped with a sedimentation tank, which contains a high amount of organic matter and is conducive to the production of biogas;

5. If the system is damaged during the operation of the device, the system will be able to automatically restore the processing efficiency of the principle in a short period of time;

6. The equipment has strong abilities to degrade organic matter, adsorb and flocculate during operation, resulting in high wastewater treatment efficiency;

In addition to adsorption biodegradation methods, there are also hydrolysis aerobic method, sequencing batch activated sludge method, aerated biofilter method, upflow anaerobic sludge bed method, anaerobic expanded granular sludge bed method, and membrane bioreactor method for treating food wastewater.
