A waste water purification plant for biological treatment, and optionally mechanical and/or chemical treatment, of biodegradable material present in an aqueous environment is provided. The plant in a biological treatment part contains at least one sensor which measures fluorescent emission and/or variation therein of at least one characteristic biogenic fluorophore present in the biological treatment part which comprises a mixed culture of microorganisms, and which plant further includes a data processing device connected to the at least one sensor and a control device connected to the data processing device. The plant also contains a portion for determining quality and/or quantity of the material to be treated including an additional mixed culture of microorganisms, a sample of the biodegradable material and a further sensor or sensors for measuring fluorescent emission. |
