A process for treating colored liquid comprises a step of contacting a colored liquid and functional water generated by electrolysis of a water solution of an electrolyte under light irradiation, to decolorize efficiently and stably to a low chromaticity.

Method for treating colored liquid and apparatus for treating colored liquid

A method is provided for culturing a microorganism in a culture medium containing a carbon source and an electrolyzed water containing not more than 0.4 ppm chlorine produced during electrolyzing water containing an electrolyte in an electrolytic cell. The culture medium may also contain a carbon source and an acidic water having a pH value of 1-4 and a redox potential from 800 mV to 1500 mV. The acidic water is obtained by electrolysis of water in an electrolytic cell. Further, the culture medium may contain a carbon source and an alkaline water having a pH value of 10-13 and a redox potential from &minus;1000 mV to 800 mV. The alkaline water is obtained by electrolysis of water in an electrolytic cell. The redox potential for the alkaline water is determined by the use of a platinum electrode as a working electrode and a silver-silver chloride electrode as a reference electrode. The microorganism may be selected from strain J1, strain JM2N, or an artificial recombinant. The microorganism can decompose a pollutant, such as phenol, toluene, cresol, trichlorethylene and dichloroethylene.

A method for decomposing halogenated aliphatic hydrocarbon compounds or aromatic compounds characterized by contacting the compound to be decomposed with functional water under light irradiation, wherein the functional water is characterized by a hydrogen ion concentration (pH) of 1-4, an oxidation-reduction potential of 800-1500 mV (working electrode: platinum, reference electrode: silver-silver chloride) and a chlorine concentration of 5-150 mg/l, and the irradiation is carried out with light of a wavelength of 300 nm or more, with an intensity of 10 mW/cm or less. This method is carried out at room temperature under the atmospheric pressure. An apparatus for the method is also provided.

The present invention relates to a self-timer device for a motion picture camera which presents a second motor switch connected in series with the first motor switch to be closed by means of the release means at the time of the camera release, the first timer means including a governer mechanism for actually starting photographing, closing the second motor switch after the elapse of a certain determined time from the automatic photographing setting and the second timer means for stopping the camera release after the elapse of a certain determined time from the actual starting of photographing, so as to open the first motor switch and terminate the photographing. In this manner the first timer means is driven by means of a spring means as a driving source while the second timer means is driven by means of the camera driving motor as driving source and controls the timing of the start and stop of the photographing at the time of the automatic photographing.
