Title: Treatment of fluorine-containing waste water
Inventor: KAWAMURA KAZUSHIGE
IPC: C02F1/58
Filed: 1995-01-09
Abstract: PURPOSE:To efficiently treat waste water contg. boron and high-concn. fluorine by adding a calcium compd. to the prescribed waste liquid formed by treating waste coal combustion gases with a prescribed absorbent liquid to adjust its pH, then adding aluminum chloride and hydrochloric acid to the liquid to effect reaction and treating the liquid with a calcium compd.-contg. soln. CONSTITUTION:The calcium compd., for example, Ca(OH)2, is added to an original liquid of the waste water which is obtd. by treating the waste coal combustion gases with the absorbent liquid contg. the calcium compd. and has the fluorine concn. of >=500ppm and contains the baron, by which the pH adjustment of the liquid is executed. The pH is preferably adjusted to about 5. Aluminum chloride is thereafter added to the liquid so as to attain an aluminum concn. of >=300ppm and the hydrochloric acid is added thereto to effect the reaction and to lower the pH down to about 3. The fluorine in the waste water is then decomposed and is discharged outside the system by a co- precipitation effect. The waste water is treated with the soln. contg. the calcium compd. after this reaction, and the fluorine is removed as calcium fluoride outside the system. Then the pH of the system is adjusted to about 7.

Abstract: PURPOSE:To realize a probe scanning under a practically sufficient speed in an information recording and reproducing device, etc., performing the recording and reproducing of the information while scanning a probe along the surface of a recording medium. CONSTITUTION:The luminous flux of a linearly polarized light emitted from a light source 101 passes through a polarization plane maintaining optical fiber 102 and is made to be the form of an evanescent wave via a metallic mask 103 having a minute opening part 104 smaller than the wavelength of the light. Then, since the metallic mask and a magneto-optical recording medium are of conductors, a distance (d) can be sensed from a capacitance between them by fitting electrodes on both of them and by connecting both electrodes to a capacitance-distance senser 130 with wires. Consequently, since the area of the part of the metallic mask 103 facing to the magneto-optical medium 105 is greater as compared with the area of the minute opening part 104, accurate and broad band information of the distance (d) are obtained, Thus, a high speed probe scanning is made possible by controlling the position of the minute opening part 104 while feeding back the information of the distance (d) to an actuator 114.
