摘要： PURPOSE:To reduce the range of control of concentrated gas and to rapidly return it to the original concentration by using a gas separation membrane module capable of sufficiently reducing the rate of change in concentration of a specified component in concentrated gas as compared to the rate of change in concentration of the specified component in natural gas. CONSTITUTION:In the treatment for separating a specified component from natural gas at a specified concentration by using a separator, one fan (or compressor) 3 and the other fan (or vacuum pump) 4 are driven to feed the natural gas from a natural gas source 1 to a gas separation membrane module 2. A pressure adjusting valve 6 is adjusted to set differential in pressure across the membrane of the gas separation membrane module 2 to a prescribed value and the natural gas is subjected to separation treatment. In this way, concentrated gas of the specified component is allowed to flow out from an outlet 21 on the impermeable side of the gas separation membrane module 2. The change in concentration of the specified component is detected by a gas concentration detecting element 5 and a flow control valve 7 is operated based on the detected signal, thereby the concentration of the specified component can always be kept constant.

摘要： PURPOSE:To reduce the reaction time, to stably and efficiently treat waste liq. and to obtain high-quality treated water at a low cost by flocculating the waste liq., separating solid and liq. and subjecting the separated liq. to wet catalytic oxidation. CONSTITUTION:The waste water as a raw liq. having a high content of org. matter and obtained by crushing night soil and/or septic tank sludge, etc., is firstly added with a flocculant and directly flocculated. The flocculated water is then subjected to solid-liq. separation. The separate liq. is introduced into a wet catalytic oxidation tower 2. A pipeline 13 for supplying an oxygen-contg. gas such as air provided with a compressor C is connected to an inlet pipeline 12, the oxygen-contg. gas is blown into the raw liq. to be subjected to wet catalytic oxidation, and the liq. is introduced into the oxidation tower 2 and oxidized in the presence of catalyst. The liq. is stably treated in a short time by this method, and high-quality treated water is efficiently obtained at a low cost.

摘要： PURPOSE:To reduce the clogging of a packed bed, by forming the lower part of a wet oxidizing tower into an inverted conical space part and stagnating the org. SS in waste water in said space part in a flowing state to dissolve the same. CONSTITUTION:In an apparatus for the wet oxidizing treatment of waste water containing a substance to be oxidized, the outer shape of the lower part of a wet oxidizing tower 1 is formed into an inverted conical part 7 whose cross- sectional area becomes small downwardly to form a space part (a) in said conical part 7 and a waste water/air introducing port 8 is further provided to the lower end of the conical part 7. When waste water is introduced from the introducing port 8, said waste water flows through the space part (a) of the inverted conical part 7 upwardly to go toward the packed bed 6 but, since the flow velocity of the waste water becomes lower toward the upper part of the space part (a), the SS in the waste water is stagnated in a flowing state and the greater part of org. SS is dissolved to reach the packed bed 6. Therefore, the clogging of the packed bed is reduced and waste water is treated efficiently in low cost.

摘要： PURPOSE:To enhance the thermal efficiency of equipment and to simplify the equipment by connecting a sludge drying process and a melting furnace and directly spraying dried sludge to a coke packed bed to melt the same. CONSTITUTION:The dried sludge from a low temp. fluidized type drying oven 3 is ground into a powdery form suitable for the spraying to a melting furnace 2 by a drying and grinding machine 6 to be charged in a coke packed type melting furnace 2. The powdery dried sludge is sprayed into the coke packed type melting furnace 2 from the tuyere 13 opened to a coke packed bed 12 along with oxygen-containing gas. In the same way, the dust in the exhaust gas recovered by a cyclone 7 is sprayed into the melting furnace 2 from the dust spray tuyere 15 equipped with an auxiliary burner 14 opened to the coke packed bed 12. By this method, the combustible component of the sludge is burnt and the non-combustible component thereof is ashed and further melted to become slag which in turn flows down through the coke packed bed 12 to be discharged from the tapping port 16 of the coke packed type melting furnace 2.

摘要： PURPOSE:To reduce the amount of cost for melting treatment by providing, to a waste melting furnace, a fluidized bed type melting furnace main body, a cyclone provided to an exhaust passage and a dust supply passage returning the solid recovered by the cyclone to a tuyere. CONSTITUTION:Oxygen-containing gas for burning coke is supplied to a coke packed bed 7 from a tuyere 14 and the waste 1 charged to a melting furnace main body 3 is melted by the heat of combustion of coke (c). The fluidized bed 20 of the waste 1 is formed on the upper surface of the coke packed bed 7 and cyclone 5 recovering the solid (d) in exhaust gas is provided to the exhaust passage 4 of the melting furnace main body 3, and the solid (d) recovered by the cyclone 5 is supplied to the tuyere 14 by a dust supply passage 6. As a result, the furnace can be made compact as a whole and it is unnecessary to provide a dryer apart from the furnace, and the amount of coke required in melting treatment can be reduced.
