    摘要: Sample water is introduced into a water bath in which aquatics live, and a gas sparingly soluble in water and giving no effect upon biological activities of aquatics is supplied to the water bath. The supplied gas and carbon dioxide gas generated by the biological activities of aquatics are collected, and a change in water quality of the sample water is detected from a concentration of carbon dioxide thus collected.Change in water quality of sample water can be rapidly detected thereby, which can be applied to detection of whether toxic materials are contained, for example, in river water flowing into a water purification plant, or not.

    摘要: There are disclosed methods for removing fluorine values from fluorine-containing waste waters, in which aluminum ions are added to fluorine-containing waste water to convert fluorine to hydroxyfluoride complexes, adding phosphoric acid or phosphate and calcium compound are added to form fluoride apatite with residual fluorine in the waste water, and the hydroxy-fluoride complex and fluoride apatite are removed from the waste water.When waste water containing a phosphate in addition to fluorine is treated, the waste water is divided, according to the fluorine concentration, into concentrated waste water having a high fluorine concentration and dilute waste water having a low fluorine concentration; calcium compound is added to the concentrated waste water to form calcium fluoride, aluminum ions are added to the dilute waste water to form a hydroxy-fluoride complex; the so treated dilute waste water is mixed with the phosphate-containing concentrated waste water from which the precipitated calcium fluoride has been removed, calcium compound is added to the mixture to form fluoride apatite, and the hydroxy-fluoride complex and fluoride apatite are removed from the mixed waste water.
