摘要： PURPOSE:To improve the assimilability of a cellulosic substance by the titled microorgansim capable of hydrolyzing cellulose and cultivate the titled microorganism efficiently, by hydrating the cellulosic substance, and treating the hydrated cellulosic substance with ozone. CONSTITUTION:A cellulosic substance 1, e.g. rice straw, wheat straw or bagasse, is mixed with an aqueous solution 2 containing a culture medium components, e.g. an inorganic nitrogen or inorganic salt, in a mixer 3 and hydrated. In this case, the moisture content of the cellulosic substance is adjusted to 90% or less. The hydrated cellulosic substance is then brought into contact with ozone generated by an ozonizer 7 in an ozone treating apparatus 4 by the gas-solid contact method to decompose the lignin the cellulosic substance 1. The amount of the ozone to be used is 0.005g or more based on one gram dried weight of the cellulosic substace 1. The cellulosic substance 1 is then fed from a sterilizing tube 10 to a cultivating tank 12 to cultivate the microoganism capable of hydrolyzing the cellulose therein.

摘要： PURPOSE:To make the granulation of the titled feed easy, by inoculating fibrous straws heat-treated with NaOH with a bacterium which decomposes cellulose and Basillus natto. CONSTITUTION:Fibrous straws which are ground by the grinding process 1 to have a sectional diameter 12-65 mesh and length 5-20mm. are fed to the pretreating process 2. They are dipped in an NaOH aqueous solution at 80-100 deg.C, heat-treated, washed (3), and pressed to have a water content 10-20wt%. They are then sterilized under pressure, fed to the fermentation process 4, inoculated with a bacterium which decomposes cellulose and Bacillus natto, fermented aerobically under heating so that the straws are attached each other to give a pellet shaped matter having particle diameters 5-30mm.. The pellets are fed to the drying process 5 and dried at 70-90 deg.C to give a pellet shaped coarse feed.

摘要： PURPOSE:To enable to effectively carry out the separation of mud in a stable condition against load variation of mud in reaction vessel, by providing water supply tube opening at the lower part of outlet of floating mud of mud separation tower and also, opening the lower tip end at the lower part of floating mud separation part. CONSTITUTION:The floating mud 4 is stayed on the floating separation part 8 when the mud load of the denitrification vessel 1 is large. At this time, only gas bubble and liquid are drawn out from the draw-out opening 10 and the mud is concentrated and then, the opening 10 is blocaded. Then, the liquid is sucked up from the opening 10 through the water supply tube 12 and the mud 4 is drawn out accompanied by the liquid. Recovered mud 4 sent back to the vessel 1 through the line 13, 14 and a part of it is drawn out of the system from the line 15. Treating water of the separation tower 6 is flowed in the sedimentation separating vessel 3 from the inclined connecting tube 7 and mixing of the mud 4 in the vessel 3 is prevented by the inclination of the tube 7. Hereby, stable continuous operation of mud separation apparatus is carried out.

摘要： PURPOSE:To accomplish efficient nitrification waste containing NH 4-N in high concentration and including almost no organic compounds through aeration thereof with a large amount of air. CONSTITUTION:The pH of a waste wster containing almost no organic compounds, with the ratio BOD/NH 4 -N bein less than 0.01 and the amount of NH4 -N being 100 to 1,000 ppm, is adjusted to 7 to 9. The waste water thus pH-controlled is aged at a load of NH 4 -N of 1 to 4 kg/m . day and an oxygen moving speed of 5 to 30 mMO2/1.h. In this manner, the waste water containing a high concentration of ammonic can be efficiently nitrified. When the waste contains organic compound, an organic removal process is set before the aeration process. In addition, selective removal of NH 4 -N is performed by using an adsorbent as zeolite. Then, the desorption if NH 4 -N fron the absorbent is performed by using a solution of NaCl, NaHCO3 or the like. When the amount of NH 4 -N in the desorption liquid reaches 100 to 1,000 ppm, nitrification is performed.

摘要： PURPOSE:In a solid-liquid contactor an outer cylinder for solid-liquid separation is installed at the outside of a tube body in such a way that the space between the tube and the cylinder is larger than the size of solid particles, whereby the liquid is always present in the tube to provide effective solid-liquid contact. CONSTITUTION:Gas is injected from a blowing nozzle 3 into a tube 2 installed in a water tank 1. The injected gas produces an uprising liquid flow in the tube 2 causing solid particles 5 to rise up in the tube 2. The solid particle 5 which starts flowing in the tube 2 is provided with floating force by the liquid and so smoothly rises up in the tube 2. When the particles reach the top of the tube 2, they fall down through space between the water tank 1 and an outer cylinder 6, maintaining good contact with the liquid. Thus, the solid particles 5 sucessively flow to provide good contact with the liquid.
