Morphology
The meaning — a layer or bed inhabited by bacteria used in treatment — is directly and literally composed from 'bacteria' (microorganisms) + 'bed' (a layer or base). Although the term is technical, its formation follows a transparent noun+noun compounding pattern that a B1 learner who knows both words can readily infer.
Etymology
Bacteria bed comes from the image of a 'bed' of sand or gravel where tiny bacteria live and eat sewage. When dirty water flows over this bed, the bacteria break down the waste, so the phrase means a layer used to 'clean' wastewater.
