摘要： The present invention relates to a testing method for testing a state of an aeration tank in a wastewater treatment facility that uses activated sludge. The testing method comprises obtaining a difference between: a sedimentation amount when a given period of time has elapsed after an activated sludge mixed liquid collected from the aeration tank and water having a higher dissolved oxygen concentration than the activated sludge mixed liquid are poured into the same container and mixed together; and a sedimentation amount when a period of time equal to the given period of time has elapsed after the activated sludge mixed liquid collected from the aeration tank and water having a lower dissolved oxygen concentration than the activated sludge mixed liquid are poured into the same container and mixed together.

摘要： The present invention relates to an apparatus for generating electrolyzed water, which generates hydrogen water comprising hydrogen molecules in a high concentration. Two sheets of porous cathode plates each provided on the surface thereof with an ion-exchange membrane are provided across an anode plate so as for the ion-exchange membranes to face the anode plate and so as to form a space allowing water to flow therethrough, between the anode plate and each of the ion-exchange membranes, and thus four electrolysis chambers are formed. Thus, here is provided an apparatus for generating electrolyzed water in which there are formed a first water path and a second water path to feed water respectively to the first electrolysis chamber and the second electrolysis chamber formed between the anode plate and the cathode plates, and a third water path to feed water to either of the third electrolysis chamber and the fourth electrolysis chamber formed on the sides of the cathode plates on the other side of the anode plate and to feed the treated water passing through the electrolysis chamber to the other electrolysis chamber.

摘要： The present invention relates to a hydrogen water and sterile water-generating device that generates hydrogen water and sterile water by electrolysis. The hydrogen water and sterile water-generating device includes an electrolysis part that has at least two electrodes and electrolyzes water, a water introducing channel that introduces water into the electrolysis part, and a switch mechanism that switches the polarity of the electrodes between positive and negative, and hydrogen water and sterile water are generated in the same path by the switch mechanism switching the polarity of the electrodes between positive and negative during electrolysis.

摘要： The present invention relates to a shower device that changes supplied typical water to hydrogen water and sprays the hydrogen water. In a hydrogen water shower device including a storage container for a hydrogen generating agent, the storage container for a hydrogen generating agent has a surface with an opening section, and the storage container for a hydrogen generating agent is disposed relative to a water passage between a water supplier and a shower discharger so that water enters the storage container for a hydrogen generating agent from the surface with the opening section and exits from the same surface to the water passage.

摘要： This invention relates to an operation management system, a diagnostic method, and an operation management method for a wastewater treatment facility which uses activated sludge. The operation management system for a wastewater treatment facility includes: a storage means for storing a reference value for each index of a plurality of indexes indicating a state of an aeration tank; an input means for inputting a measured value of the index; a comparison means for comparing the input measured value with the reference value for each index, and categorizing each measured value as one of being within a reference value range, over the reference value, or less than the reference value; a storage means for storing diagnostic patterns, in which the diagnostic patterns are classified according to a combination of categories of: within the reference value range, over the reference value, or less than the reference value for each index, using the reference value as a reference; a checking means for checking a combination of categories of each index of the measured values against a combination of categories of each index of the diagnostic patterns, and extracting a diagnostic pattern which the combination of categories has matched; and a display means for displaying the diagnostic pattern which the combination of categories has matched.
