摘要： PURPOSE:To efficiently remove hydroxylamine, by bringing thiobacillus ferrooxidanse into contact with hydroxyl amine-contg. waste water held under an acidic condition, and aerating the waste water using oxygen and/or air. CONSTITUTION:Fe is supplied to a thiobacillus ferrooxidanse (bacteria TF)- cultivating vat 12 by a Fe supply means 11, while the bacteria TF are introduced into a hydroxyl amine-treating cell 14. Hydroxyl amine-contg. waste water is introduced into the purifying cell 14 by a supply means 13. Water purified in the purifying cell 14 is fed together with the bacteria TF through a solid-liquid separating means 15. The purified water is discharged by a purified water-discharging means 16. Bacteria TF-contg. sludge is partially disposed outside the treating system by a sludge-disposing means 17, while the remainder is fed toward the bacteria TF-cultivating vat 12 by a sludge-returning means 18.

摘要： PURPOSE:To reduce COD by an expensive and simplified biological treatment of waste water in which activated sludge is grown with sulfur particles as the main nutritive source, the activated sludge and waste water containing polythionic acid are mixed, and then the sulfur is reduced stepwise. CONSTITUTION:When activated sludge is grown with sulfur particles as the nutritive source under an aerobic condition, the polythionic acid-decomposing bacteria are also proliferated with the sulfur-oxidizing bacteria. Then, waste water containing polythionic acid and sulfur particles are flowed into the activated sludge in order to conduct the biological oxidation treatment of the waste water under an aerobic condition until polythionic acid is oxidized to sulfuric acid. In this case, when the treatment of the polythionic acid is confirmed, the charge of sulfur particles is reduced stepwise. Thus, COD present in waste water containing polythionic acid can be easily reduced by such an inexpensive and simplified treatment method.

摘要： PURPOSE:To obtain dischargeable purified water with high efficiency, by adding an NO2 salt to waste water containing NH4 , polythionic acid, S-N compounds, etc., oxidizing the waste water with sludge containing sulfur bacteria and nitrifying bacteria, and then reducing nitrogen compounds in the waste water to N2 gas. CONSTITUTION:Waste water containing NH4 , NO2 , NO3 , polythionic acid and S-N compounds is introduced into a disposal vessel 3.The waste water in the vessel 3 is kept at pH about 4 or less and a temperature of about 60 deg.C or higher. NO2-N, having a concentration at least equal to an expected N concentration of the S-N compounds, is fed to the waste water, and the waste water is agitated to decompose the S-N compounds into N2 or N2O gas and SO4 . The treated waste water is let flow into a pH-adjusting vessel 4, where the waste water is neutralized at pH about 6-8. Thereafter, the waste water is oxidized by sulfur bacteria in an aerobic disposal vessel 11 containing a sulfur compound, e.g. SCN- or the like, as a nutritious source. the waste water is further introduced into an anaerobic denitrifying vessel 2 containing denitrifying bacteria, where the waste water is agitated and fluidized to reduce most of NO2 to N2 gas.

摘要： PURPOSE:To prevent the adhesion of organisms to a plant using seawater with a simple method by removing dissolved oxygen in the seawater in one of the series wherein the supply of seawater is stopped, and providing alternately the period for retaining the deoxidized seawater and the period for feeding the seawater. CONSTITUTION:After the concn. of the dissolved oxygen reaches almost zero in the entire closed loop, a circulating pump 10 is stopped, and the supply of a deoxidizer is stopped. Valves 19 and 20 are completely closed. The deoxidized seawater is retained in a reserve series which is isolated by valves 15, 19, 20, and 16 for a specified period. Then the valves 15 and 16 are opened to supply seawater into an evaporator 5-2 from a supply pipe 4-1, and the deoxidized seawater is pushed out to the outside of the system through a discharge pipe 4-2. After valves 13 and 14 are closed, the seawater is deoxidized between the valves 13 and 14 which are made reserved, and retained for a specified period.

摘要： PURPOSE:To obtain highly reliable effect for preventing sticking organisms by closing tightly stand-by lines, stopping flow of water completely, thus blocking the supply of food and oxygen. CONSTITUTION:For example, in a system consisting of plural lines of installation, valves 11, 12 are opened and valves 13, 14 are closed, and carbureters 5-2 is reserved as a stand-by equipment. Then, sea water is filled between the valves 13, 14. The system is allowed to stand under this condition for a specified period. Thereafter, the valves 13, 14 are opened, and the line is exchanged with another line of the system. By this method, the supply of food and oxygen are blocked and sticking of organisms is prevented.
