For bio-electrically generating electric power from organic ingredients of a waste water flowing in a flow direction, an anode is immersed in the waste water in a first spatial area, and oxygen is supplied to a cathode which is electrically connected to the anode and arranged in a second spatial area delimited from the first spatial area by means of a proton-permeable membrane. A voltage between the anode and the cathode is increased by a DC/DC converter located at the anode and the cathode, and a further voltage between a further anode in said or a further first spatial area and a further cathode in said or a further second spatial area is increased by a further DC/DC converter located at the further anode and the further cathode. A DC voltage link is charged with the DC/DC converter and the further DC/DC converter connected in parallel to the DC voltage link.

An electrolytic ion water generation method for generating strong electrolytic ion water having a pH value higher than a reference pH value through use of the same generation apparatus as an electrolytic ion water generation apparatus configured to generate electrolytic ion water having the reference pH value by setting an amount of raw water, which is to be supplied into a cathode chamber of an electrolytic bath, to be smaller than that of the raw water used for generating the electrolytic ion water having the reference pH value and setting generation conditions other than the amount of the raw water to the same generation conditions as those for generating the electrolytic ion water having the reference pH value. The raw water amount is set to a raw water amount calculated based on the following expression: pH=14+log [OH.sup.−].
