    • 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.
    • 废水处理设备通过其中放置碳酸钙矿物9的厌氧池3和其中放置碳酸钙矿物9的需氧罐15处理含有有机物,氮,磷和过氧化氢的氟废水,并进入 其中生物处理的水从另一系统的处理设备444引入。 因此,废水中的氟可以通过放置在厌氧池3中的碳酸钙矿物9和形成氟化钙11的需氧罐15进行处理。废物中的表面活性剂等的有机物质 水可以被包含在生物处理水中的微生物处理。 此外,可以处理硝酸盐氮以便在厌氧池3中还原成氮气,同时可以处理氨氮和亚硝酸盐氮以在需氧罐15中被氧化。也就是说,废水处理设备 可以高效地处理废水中的表面活性剂,氮,多氯化铝,大分子凝结剂,过氧化氢和磷光体,从而可以减少废物。

    • An object of the invention of the present application is to drive data signal lines accurately by pulse width modulation driving and display gradations accurately. A PWM pattern generating circuit (12) generates 2q sets of PWM patterns associated with combinations of a gradation and the polarity of a gradation voltage. A selector (15) selects one PWM pattern from among the 2p+q PWM patterns, based on gradation data and a pattern set number. A charge and discharge control circuit (16) controls a charge and discharge circuit (17) to apply a charge voltage and a discharge voltage to a data signal line in a switching manner, based on the selected PWM pattern. One correction pulse may be selected for each data signal line from among a plurality of types of generated correction pulses, and a charge voltage may be applied to the data signal line based on the correction pulse. A plurality of charging transistors may be provided, and a charging transistor to be used may be specified for each data signal line, according to the temperature.
