摘要： PURPOSE:To reduce greenhouse effect by absorbing carbon dioxide in exhaust gas by seawater to recover the same and supplying this seawater to an algae culture basin. CONSTITUTION:The exhaust gas of a combustion furnace 1 issues from a blower 2 to be sent to an absorbing tower 3 and carbon dioxide in the exhaust gas is absorbed in seawater. The absorbing solution is supplied to an algae culture basin by a pump 4 and the exhaust gas wherein a part of carbon dioxide is absorbed is discharged to the atmosphere from the top of the absorbing tower 3. The seawater containing the algae cultured in the culture basin 5 is sent to a dehydrator 7 by a pump 6 to remove the seawater while the algae are dried if necessary to be applied to other use. By this constitution, the discharge of carbon dioxide to the atmosphere can be suppressed.

摘要： PURPOSE:To sterilize the spoiling microorganisms in a closed loop by isolating a sea water system in a plant from the sea water intake area and release area of said plant and injecting bacteriophage intermittently into the sea water retained in the closed loop obtd. in such a manner during the stop of the sea water flow. CONSTITUTION:An intake shut off gate 8 and a release water shut off gate 9 are closed to provide the closed loop of the sea water system in the plant during the stoppage of the sea water flow in the plant utilizing the sea water. The bacteriophage 7 is intermittently injected into the sea water retained in the closed loop to sterilize the spoiling microorganisms existing in the closed loop. As a result, the spoiling of the marine organisms is effectively prevented without giving any ill effects at all to the other marine organisms.

摘要： PROBLEM TO BE SOLVED: To secure an excellent film cooling performance of a cooling structure by improving the adhesion of cooling air to the inner surface of a combustion chamber. SOLUTION: The combustor has grooves 34, cooling channels, communicating with cooling air intake ports 35 and cooling air outlet ports 36 for convection cooling as the cooling air taken from the cooling air intake ports 35 flows toward the cooling air outlet ports 36. The grooves 34 are slanted in the swirling direction of the combustion gas swirling inside to make cooling air intake channels for letting the cooling air flowing out of the cooling air outlet pots 36 flow out in the swirling direction of the combustion gas.

摘要： PROBLEM TO BE SOLVED: To reduce an oxygen supply and a methanol supply by reducing a nitrous acid state nitrogen in a waste water to a gaseous nitrogen with denitrifying bacteria under an anaerobic condition after converting an ammonia nitrogen in the waste water to the nitrous acid state nitrogen. SOLUTION: Nitrite bacteria-carrying beads 39 are packed in a reactor 31 for converting to nitrous acid, and a waste water containing ammonia nitrogen is introduced, and the ammonia nitrogen in the waste water is converted to the nitrous acid state nitrogen by fluidizing the waste water with air bubbles 4 generated with a diffuser 3 by using the air from a blower 2. After that, the nitrous acid state nitrogen in the waste water is introduce into a denitrifying reactor 21 and reduced to gaseous nitrogen with the denitrifying bacteria in the denitrifying reactor 21. In this way, the oxygen supply and the methanol supply are reduced.

摘要： PURPOSE: To recover vanadium ion as solid V2 O4 in high yield by specifying the pH of soln. and ORP(oxidation/reduction potential) and precipitating the V ion as V2 O4 . CONSTITUTION: The incineration ash and water are charged into a dissolution tank 1 and mixed by an agitator. Sulfuric acid is injected from a tank 11 and a reducing agent from a tank 12, the pH of the liq. mixture is controlled to 2-3 and the ORP to 200-400mV by using a pH meter 4, ORP meter 3, controllers 5 and 6, etc., hence the elution rate of V from the ash is increased, and solid is separated from the liq. mixture. The filtrate is then sent to a reaction tank 15. Ammonia is injected from a tank 24 and hydrazine from a tank 26 and mixed by an agitator 16. The pH of the soln. is controlled to 5-7 and the ORP to -100 to 100mV by using a pH meter 17, ORP meter 18, controllers 19 and 20, etc., and the solid (V2 O4 cake) is removed by a centrifugal separator 28. Consequently, the raw ash is treated at a high concn., and the equipment and tanks can be made compact.

摘要： PURPOSE:To determine production of carbon dioxide clathrate quantitatively by previously separating solid state clathrate mixed in a solution contained in a reaction vessel through a filter and then measuring electric conductivity of solution subjected to pretreatment. CONSTITUTION:Sample water 12 containing chlorine ions is injected through a sample liquid injection pump 13 into a reaction vessel 11 while furthermore carbon dioxide 14 is injected through an injection pump 15. The vessel 11 is placed in a cooling water tank 16. Carbon dioxide clathrate reaction is then promoted while stirring water and carbon dioxide by means of a stirrer 18 coupled with a motor 17. Reaction temperature and reaction pressure are measured, respectively, through a thermometer 19 and a pressure gauge 20 and recorded on a recorder 21. At that time, a solution discharge valve 22 for measuring electric conductivity in the reaction vessel is opened to produce pressure difference with respect to the atmospheric pressure thus separating solid state carbon dioxide clathrate through a filter 24 disposed in front of a vessel 23 for measuring electric conductivity in the reaction vessel. Solution mixed with no carbon dioxide clathrate is then filled in the vessel 23 and electric conductivity thereof is measured by means of an electric conductivity meter 26 associated with a sensor 25 for measuring electric conductivity. Measurement of electric conductivity is then converted through a data analyzer 27 into a production quantity of carbon dioxide clathrate.

摘要： PURPOSE:To speedily treat the waste water incorporating emulsified oil which is difficult to treat heretofore to a desired lower oil concentration by bringing the activated sludge containing micro-organism (sticking particles taking away with the oil containing waste water into contact with the oil containing waste water. CONSTITUTION:For example, the activated sludge picked from a ship sewage treating system is put in a fluidized bed type micro-organism experimental device 1 consisting of an aeration reacting part 2 and a sedimentation part 3, and 3-5W/V% refined sand are added into the aeration reacting part 2, consisting of 100mg/l glucose, 100mg/l ammonium chloride, and 100mg/l dipotassium hydrogenphosphate, and the aeration is continued for seven days, thereby the activated sludge is stuck to the sand particles. Next the bilge which is picked from actual ship bilge tank is supplied to the aeration reacting part 2 from a bilge storage tank 4 step by step and simultaneously air is supplied to the aeration reacting part 2. Thus, emulsified oil can easily be decomposed into gaseous carbon dioxide and water.
