Description

Technical Field

[0002] Carbon source refers to the source of carbon elements required for the growth, reproduction and metabolic activities of microorganisms. The preparation device of microbial carbon source is mainly used to convert organic waste into carbon source that can be used to promote microbial growth and metabolism, thereby improving the efficiency of the biological treatment process; the aquatic processing industry (such as eel farms, seafood processing plants) produces a large amount of high-protein, high-fat waste (such as dead eels) every day. Such waste is easy to rot and stink, and breed bacteria. If it is directly landfilled or incinerated, it will not only cause a waste of organic resources, but also pollute the soil, water bodies and atmosphere; the existing carbon source preparation system has significant defects: the manual adjustment of the baffle position has low accuracy, the oil layer is easy to mix with water, and the purity of the recovered oil is poor; the static stirring blades are difficult to adapt to changes in material viscosity; the fixed-volume fermentation tank is difficult to adapt to the fluctuating feed amount of waste, which can easily cause the equipment to be idle or overloaded.
