摘要： PROBLEM TO BE SOLVED: To produce highly oxidative water containing ozone and the like in excellent electrical efficiency with high productivity by dissolving an oxygen- rich gas in water under high pressure, then lowering the pressure to generate microfine bubbles of the oxygen-rich gas and exposing the microfine bubbles to the pulsed electric discharge. SOLUTION: Water is introduced into a high-pressure tank, an oxygen-rich gas is blown from a high-pressure bomb 6 through an aerator 7 into the water in microfine bubbles so that the oxygen-rich gas is dissolved in the water. At this time, the pressure in the high-pressure tank is measured with a pressure gauge 5 to adjust the pressure to several to several tens atmospheric pressure. The water saturated with oxygen-rich gas is transferred to the low-pressure tank 2, the pressure-reducing valve 9 is opened to reduce the pressure in the low-pressure tank. At this time, the oxygen-rich gas dissolved in the water is supersaturated with the oxygen-rich gas to generate microfine bubbles wholly in the water. High-voltage pulses are applied from the pulse power supply to the electrode 3 to generate ozone whereby the objective high-oxidative water including high concentrations of ozone and/or OH radical is obtained.

摘要： PROBLEM TO BE SOLVED: To attain efficient electric discharge in water in a discharge vessel, to modify the water and to efficiently obtain highly oxidizing water by applying AC pulse voltage to electrodes disposed opposite to each other in a non-contact state in the water in the discharge vessel and carrying out underwater electric discharge by an electric field generated in the discharge vessel by induction at the time of the reversal of potential. SOLUTION: AC pulse voltage is applied to electrodes 3 disposed opposite to each other in a non-contact state in water 2 in a discharge vessel 1 and underwater electric discharge is carried out by an electric field generated in the discharge vessel 1 by induction in the reversal of potential. By the underwater electric discharge, oxygen in the water is excited to generate ozone and the water 2 is also excited by the action of UV generated in the discharge to form OH radicals. The ozone and the OH radicals are dissolved in the water to increase the concentrations of ozone and OH radicals in the water and the objective highly oxidizing water is obtained. When fine bubbles comprising an oxygen-rich gas are allowed to exist in the water in the discharge vessel 1 and the water is exposed to a discharge atmosphere, water 2 having higher oxidizing activity is easily obtained.

摘要： PROBLEM TO BE SOLVED: To provide an aerobic treatment method for an org. waste soln. not making an apparatus large-scaled, generating no problem of residual ozone, not becoming high in cost and capable of reducing or eliminating the generation of excessive sludge. SOLUTION: An org. waste soln. introduced from a route 7 is aerobically treated by aerobic bacteria in an activated sludge tank 1 (aerobic treatment tank) and the treated soln. is introduced into a sedimentation apparatus 2 to be objected to solid-liquid separation. This separated sedimented sludge 10 is modified in a modifying apparatus 18 by high voltage pulse discharge treatment. The modified sludge is returned to the activated sludge tank 1 to be again aerobically treated.

摘要： PURPOSE:To prevent by-passing of steam and weaving phenomena and to improve the efficiency of gas-liquid contact by inclining the respective racks of a rack type gas-liquid contact device in the downgrade direction from a horizontal direction and making the differences in the liquid depth on the respective racks as small as possible. CONSTITUTION:In a gas-liquid contact device which is provided with many roughly horizontal gas-liquid contact racks 2 at prescribed intervals in a body 1 of a gas-liquid contact tower and is installed alternately laterally with downcomers 3 connecting the racks vertically, the racks 2 are inclined in the downgrade direction by an angle theta of inclination corresponding to the resistance of liquid flow in such a way that the liquid which is introduced from the bottoms of the downcomers 3, overflows from inlet weirs 5, flows onto the racks 2, flows by contacting with the steam ascending from openings 4 for passage of steam and flows downward by overflowing from outlet weirs 6 does not produce any difference in liquid depth on said racks. Since the size of the angle theta varies with the physical constants of materials to be handled and operating condition, the optimum value for the same is determined by preliminary experiment.

摘要： PURPOSE:To improve tray efficiency and to increase treatment capacity by dis posing mesh-like structural members in the froth layers of the gas-liquid mixed phases on each tray in order to fine the foam in the froth layers while maintaining the superficial velocity in a gas-liquid contact column relatively high. CONSTITUTION:A gas-liquid contact column body 1 is divided to a plurality of contact reaction chambers by means of gas-liquid contact trays 2, and these are connected vertically by means of downcomers 3. Vapor ascends by passing through the opening parts 4 of the trays 2, and enters the liquid phase retained between inlet and outlet weirs 5, 6, where it undergoes gas-liquid contact. On the other hand, liquid passes through the clearance at the bottom of the downcomer 3, overflows from the weir 5, flows onto the tray 2, and overflows from the weir 6 while contacting the steam. In this case, the gas-liquid contact state is in the form of froth of gas-liquid mixed phases, and forms a froth layer A between the weirs 5, 6. The small foams (b) produced in the opening parts 4 grow to large foams B as they ascend, and the leyer A arrives at the top surface. However, there are the mesh-like structural members 7 approximately parallel with the trays 2 in the layer A and therefore the foams B are again divided into small foams (c), whereby the gas-liquid contact areas are increased.

摘要： PROBLEM TO BE SOLVED: To manufacture high pressure oxygen gas at low cost while a heavy impurity substance is prevented from being precipitated in a method of manufacturing oxygen gas by employing a low temperature separation process. SOLUTION: This method is that liquid oxygen 25 is bled out from the bottom of a low pressure fractionating tower 21 and boosted to a given feed pressure by a liquid oxygen pump 27 and evaporated and vaporized by a main heat-exchanger 17 to produce a product oxygen gas 15. In this case, oxygen gas in the main heat-exchanger 17 is caused to flow at a velocity higher than a velocity equivalent to a terminal velocity of an oxygen liquid drip with a diameter of 200 μm calculated according to a feed pressure.
