摘要： PURPOSE:To shorten an inspecting time by providing an image processing device which receives the output of an image sensing device and outputs only the image that is present in a luminance level which can be set arbitrarily, and providing a particle counter for counting the number of the images. CONSTITUTION:The mercury light emitted from a mercury lamp 1 is projected on a sample 7 through a collector lens 2, an exciting filter 3, a mirror 4 and an objective lens 5. At this time, the light in the specified wavelength region which is selected with the filter 3 is projected on the sample 7 and excites a fluorescent coloring matter. Of the excited light, the light in the specified wavelength region in cut in an absorbing filter 8 through the lens 5. The light is captured with a camera 10 through an eyepiece lens 9. Only an image in a luminance level which can be set arbitrarily is outputted. The image is processed in an image processing device 11. The image is displayed on a monitor 12. When the numbers of cells whose amounts of light emission are different are individually counted, the signal obtained by the image processing in the device 11 is linked to a particle counter 13. Thus the numbers of the cells corresponding to the intensities of the light can be read out.

摘要： PURPOSE:To decolor water having the color of raw sewage by carrying out integrated culture with water obtd. by treating raw sewage as a tracing source and a culture ground contg. water having the color of raw sewage, adding agar to the ground, carrying out screening culture, inoculating the resulting colony into a similar culture ground, carrying out shaking culture and treating the water having the color of raw sewage with the resulting two or more kinds of strains which are very effective in color separation of the color of raw sewage. CONSTITUTION:Integrated culture is carried out with soil, activated sludge or water obtd. by treating raw sewage as a tracing source and a culture ground consisting of water having the color of raw sewage, an extract of yeast, MgSO4.7H2O, KH2PO4 and NH4Cl. Agar is then added to the ground and screening culture is carried out. A colony formed on the agar is inoculated into a similar culture ground and shaking culture is carried out. Yellowish brown water obtd. by treating raw sewage is treated with basidiomycete and bacterium strains having >=15% rate of color separation of the color of raw sewage selected among the resulting strains. The yellowish brown water can be decolored at a low cost by the action of microorganisms in place of the conventional physicochemical method using ozone and activated carbon.

摘要： PURPOSE:To stably carry out membrane separation for a long period by bringing water to be treated into contact with org. matter decomposing bacteria and nitrifying bacteria in the presence of oxygen, removing the excess microbes by solid-liq. separation, and then injecting chlorine. CONSTITUTION:The contaminated river water contg. about 20-30ppm org. matter as TOC and about 1-5ppm ammonia nitrogen (NH4-N) is introduced from a line P1 for water to be treated into a biological reaction tank 1 wherein a plastic module 6 with microbes deposited on the surface and having about 200-400m /m specific surface is dipped, and oxygen is supplied from an air supply line P2 to decompose the org. matter and NH4-N in the water to be treated by the microbes. By this method, the deterioration of the membrane by the microbes and deposition of microbes on the membrane surface are eliminated, the decrease in the amt. of water to be treated and pressure drop can be avoided, and stable membrane separation is carried out for a long period.

摘要： PURPOSE:To carry out a coenzyme-requiring reaction in high efficiency, by immobilizing a conjugated enzyme to a carrier having high adsorptivity of the coenzyme compared with that of substrate and reaction product, supplying a coenzyme to a reactor filled with the immobilized conjugated enzyme and supplying a substrate to the reactor in a specific manner. CONSTITUTION:A carrier having high adsorptivity to a coenzyme compared with the adsorptivity to substrate and enzymatic reaction product is prepared beforehand. A conjugated enzyme is immobilized to the carrier, the carrier is filled in a reactor and a coenzyme of the conjugated enzyme is supplied to the reactor. Thereafter, a substrate is supplied to the reactor while reciprocally changing the flow direction of the substrate. The adsorption range of the coenzyme is restricted in the reactor by this process to enable the exclusive discharge of the reaction product.

摘要： PURPOSE:To effectively separate red tide plankton, by adding fine ferromagnetic particles to water containing red tide plankton to adsorb said plankton by said fine ferromagnetic particles. CONSTITUTION:Fine ferromagnetic particles are added to water containing red tide plankton to adsorb said red tide plankton and, if necessary, a flocculant is added to said water while thus treated water is passed through a first magnetic filter to collect said ferromagnetic particles. After a definite time, the first magnetic filter is washed and washing water containing red tide plankton and the fine ferromagnetic particles is passed through a second magnetic filter to separate the fine ferromagnetic particles and the red tide plankton. The separated fine ferromagnetic particles are re-utilized while the red tide plankton receives dehydration and concn. treatment.
