摘要： Ultrapure water having a reduced amount of TOC and a low electrical conductivity is produced in correspondence with a variation in water quality of raw water. A first water tank has an anaerobic organic matter treatment chamber and an aerobic organic matter treatment chamber which are communicated with each other at their bottom portions. Activated carbon bags are arranged in upper portions of both the chambers, and Bincho charcoal is stowed in the lower portion of the chambers. With this arrangement, carbon compounds and organic nitrogen compounds in the water to be treated are biologically treated by microbes, thereby reducing the TOC. Furthermore, nitrate nitrogen generated through the organic nitrogen compound treatment process is denitrified by the anaerobic microbe, thereby reducing the electrical conductivity of the water to be treated. Both activated carbon towers perform an advanced treatment on remaining carbon compounds and remaining organic nitrogen compounds in the water to be treated from the aerobic organic matter treatment chamber. A controller controls the rate of circulation of the water to be treated and the rate of stirring of the water to be treated on the basis of a signal from a TOC meter, thereby ensuring the water quality of the water to be treated.

摘要： There is provided an ultrapure water production system which allows recycled waste water to be microbially treated and thereby reclaimed without causing any clogging of treatment system due to abnormal propagation of microorganisms, and which allows ultrapure water with 1 ppb or lower TOC to be obtained. This ultrapure water production system includes a lower part having an anaerobic organism treatment part (12), and an upper part which is placed above the lower part via a separating wall W.sub.B having an opening (16) and which has a biological treatment equipment including an aerobic organism treatment part (1). Since lower anaerobic microorganisms and upper aerobic microorganisms consume nutrition sources for microorganisms, treated water which is difficult for microorganisms to propagate can be obtained. Further, not only TOC but also organic nitrogen compounds are treated by the microorganisms, by which treated water with low electrical conductivity can be obtained.

摘要： A method and apparatus for wastewater treatment is provided which can prevent any decrease in permeation efficiency of a submerged membrane without involving an increase in operating cost and sludge generation, and which can treat high concentration organic wastewater efficiently and without dilution. The wastewater treatment method has the steps of: concentrating domestic sludge by means of a first submerged membrane to produce thick sludge; mixing the thick sludge into a water to be treated, and introducing the water to be treated which is so mixed with the thick sludge into an anaerobic treatment portion for anaerobically treating the same; and introducing the anaerobically treated water from the anaerobic treatment portion into an aerobic treatment portion having a second submerged membrane disposed therein to subject the water to aerobic treatment. The water to be treated undergoes treatment with the thick sludge through which its dissolved oxygen content is reduced to zero and organic substances contained therein are adsorbed by the sludge for subsequent treatment in the anaerobic treatment portion.

摘要： In a third tank, calcium carbonate mineral is filled to react with fluorine in treatment water. Then, generated treatment water containing calcium fluoride is aerated and stirred so that aerobic microorganisms are propagated, by which organic matters are treated. A fourth water tank is to perform treatment of hydrogen peroxide by anaerobic microorganisms in return sludge from a sixth tank, treatment of phosphorus by slaked lime newly added in a small amount, and secondary treatment (advanced treatment) of fluorine that has already been primarily treated in the third tank. In a fifth tank, flocs are coagulated. In the sixth tank, the coagulants are settled and separated so as to be discharged as treated water. Thus, mixed waste water of hydrogen-peroxide- and phosphorus-containing fluorine waste water and organic-matter-containing waste water is treated simultaneously with low running cost and maintenance cost.

摘要： A method and apparatus for wastewater treatment is provided which can treat persistent surface active agents and coloring substances in wastewater, and which is compact and economical. The wastewater treatment method introduces water to be treated into a charcoal tank 3 packed with charcoal 10 and treats the water therein, the water to be treated having been pretreated in a pretreatment section 2. The water under treatment is introduced from the charcoal tank 3 into an activated carbon tower 6 packed with activated carbon 17 to treat the water therein. Treatment of the water in two stages, namely, treatment by bioactivated charcoal 10 and treatment by bioactivated carbon 17, makes it unnecessary to carry out backwashing of the activated carbon tower 6 and regeneration of activated carbon 17. The service life of the activated carbon can be greatly extended.

摘要： A wastewater treating apparatus has first, second and third bioreactors. Each bioreactor has, in an upper position, a reaction/sprinkling portion for exhaust gas treatment. The first bioreactor has, in a lower position, a submerged portion including an aerobic upper portion and an anaerobic lower portion. The aerobic upper portion includes a membrane filter. A membrane concentrated liquid produced by the membrane filter is introduced into a mixing tank. A mixture of an alcohol, fine powdered material and membrane concentrated liquid from the mixing tank is introduced, together with a developer-containing wastewater, into the anaerobic lower portion, so that a granular sludge is formed therein. The granular sludge contains anaerobic microorganisms in a high concentration level and is therefore capable of treating the wastewater without necessity of wastewater dilution or use of chemicals.

摘要： Drainage water containing an organofluorine compound is introduced into a raw tank (1) and then filtered through a filtration device (4). Next, a microorganism, a micro-nanobubbling auxiliary agent and a nutrient are added thereto in a first transit tank (5) while micro-nanobubbles are generated thereinto by a micro-nanobubbling machine (7), thereby giving treated water. This treated water is then fed into an active carbon column (14) and then the above-described organofluorine compound contained in the treated water is decomposed by the microorganism as described above.
