    摘要: A waste water treatment equipment treats a fluorine waste water containing organic matter, nitrogen, phosphor and hydrogen peroxide by an anaerobic tank 3 in which a calcium carbonate mineral 9 is placed and an aerobic tank 15 in which the calcium carbonate mineral 9 is placed and into which a biologically treated water is introduced from a treatment equipment 444 of another system. Therefore, the fluorine in the waste water can be treated by the calcium carbonate mineral 9 placed in the anaerobic tank 3 and the aerobic tank 15 with the formation of calcium fluoride 11. The organic matter of the surface active agent and so on in the waste water can be treated by the microorganism included in the biologically treated water. Furthermore, nitrate nitrogen can be treated so as to be reduced to a nitrogen gas in the anaerobic tank 3, while ammoniacal nitrogen and nitrite nitrogen can be treated so as to be oxidized in the aerobic tank 15. That is, the waste water treatment equipment can highly efficiently treat the surface active agent, nitrogen, polychlorinated aluminum, macromolecular coagulant, hydrogen peroxide and phosphor in the waste water, by which the waste can be reduced.

    摘要: An apparatus for treatment of fluorine waste water has an introduction tank, a main treatment tank, a calcium hydroxide tank, a polychlorinated aluminum tank, a macromolecular flocculant tank, a settling tank, and a concentration tank. Fluorine waste water is introduced through the introduction tank into a lower part of the main treatment tank through a lower inlet pipe. Also, return sludge from the concentration tank and silicon sludge from a silicon waste water treatment system are introduced into an upper part of the main treatment tank. Thus, silicon recovered from silicon waste water is recycled for treatment of fluorine waste water. Also, unreacted chemicals, which have been loaded in the calcium hydroxide tank, polychlorinated aluminum tank, macromolecular flocculant tank, are recycled. The main treatment tank has no stirrer, and thus conserves electrical energy, but can neutralize the waste water.

    摘要: When a data bit is read out from a semiconductor read only memory device, a current-mirror type sense amplifier is electrically connected through a bit line, a first selector, a selected memory cell and a second selector to a discharging line so as to check a potential drop on the bit line, and each of the first and second selectors selectively connects the bit line or the discharging line to eight columns of memory cells by increasing the component switching transistors thereof so as to space the bit line from the discharging line, thereby increasing a margin for a bit line contact.
