摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the measurement of the leak of water, in which the component of waste in creeping water can be specified and in which the damage of a measuring electrode is small. SOLUTION: In a measuring apparatus for the leak of water, an AC power supply 6 which changes a frequency ω and which can make an AC current flow across a pair of electrodes sandwiching at least two other electrodes selected from an electrode 5,... is provided. In addition, a potential difference meter 8 which measures a potential difference between the other adjacent electrodes as a pair sandwiched between the pair of electrodes is provided. In addition, an electric-characteristic-value calculating means by which an electric characteristic value (e.g. a permittivity ε) having frequency dependence is calculated on the basis of the potential difference measured by the potential difference meter 8 is provided. In addition, a leak-of-water discrimination means by which the calculated electric characteristic value between the pair of other adjacent electrodes sandwiched between the pair of electrodes is compared with every preset discrimination value so as to discriminate whether a prescribed component is contained in the leak of water is provided.

摘要： PROBLEM TO BE SOLVED: To prevent the bad effect caused by the solidification of cement fine particles when turbid water containing the cement fine particles due to spraying concrete for timbering is purified. SOLUTION: An oil component such as light oil, kerosene, gasoline, etc. is added to pressure water which is obtained by dissolving compressed air in turbid water containing the cement fine particles as a suspended substance. This pressure water is introduced into a pressure floating tank and the oil component stain SS is floated by air bubbles formed by opening the pressure water to the atmosphere to be subjected to solid-liquid separation and purified water is discharged while the sludge subjected to pressure flotation is recovered and aerobic bacteria are added by bio-remediation to decompose the oil component to take out sludge only comprising inorganic fine particles containing the cement fine particles.
