Problems solved by technology

The technologies involved in the above patents are to immerse the membrane biomodule and the electrode in the same reactor (without considering the mutual influence), the microorganisms are in a suspended state or loaded on the filler, and the source of the biofilm formation is the natural wastewater in the raw wastewater. With microorganisms, the film-forming speed is slow and has no degradation effect on refractory organic matter; in addition, the magnitude and whereabouts of the generated electric energy are not specified
