A wastewater treatment device has: an ozone generator which supplies ozone; a mixer which mixes ozone supplied from the ozone generator with wastewater and supplies ozone mixed wastewater; an ozone oxidation unit which progresses ozone oxidation in the ozone mixed wastewater while passing the ozone mixed wastewater therethrough and discharges wastewater in which the ozone has been consumed; a biological treatment unit which performs biological treatment on the wastewater discharged from the ozone oxidation unit using microorganisms; and an adjusting device which adjusts the amount of ozone to be mixed with the wastewater by the mixer so that ozone in an amount that inhibits the microorganisms of the biological treatment unit does not remain in the wastewater discharged from the ozone oxidation unit.

A coating is formed on a surface of a base material of a furnace, and includes a base layer and a sliding material layer that is formed on a surface of the base layer and contains an oxide ceramic and a compound having a layered crystal structure. The sliding material layer causes the collided ashes to be slipped and facilitates the drop off of the adhered ashes. The base material forms a heat transfer tube or a wall surface of the furnace. The coating is also applied to a coal gasification furnace, a pulverized coal fired boiler, a combustion apparatus, or a reaction apparatus containing a furnace.

Disclosed is a method for producing perchlorate, which comprises: an electrolytic step (S) wherein an electrolysis vessel (), in which a positive electrode side (A) on which a positive electrode () is arranged and a negative electrode side (A) on which a negative electrode () is arranged are divided by a cation-exchange membrane (), is used and an aqueous solution of sodium chlorate is electrolytically oxidized on the positive electrode side (A) of the electrolysis vessel (); a neutralization reaction step (S) wherein a substance an aqueous solution of which shows alkalinity is added to the aqueous perchloric acid solution that has been produced by the electrolytic oxidation on the positive electrode side, so that perchlorate is synthesized by a neutralization reaction; and a crystallization process wherein the perchlorate synthesized by the neutralization reaction is obtained as crystals. The crystallization process is composed of an evaporative crystallization step (S), or alternatively composed of three steps, namely an evaporative concentration step (S), a cooling crystallization step (S), and a separation step (S).

A light detection value determines concentration of a target component, without using a laser emitter of high laser intensity or a large light collector. By changing orientation of the laser emitter about a horizontal axis, or height of the laser emitter, a laser irradiation position on a ground or water surface is switched between first and second irradiation positions. A photodetector detects first scattered light scattering from the first laser beam at the first irradiation position, second scattered light scattering from the second laser beam at the first irradiation position, third scattered light scattering from the first laser beam at the second irradiation position, and fourth scattered light scattering from the second laser beam at the second irradiation position. A concentration calculator calculates concentration of a target component between the first and second irradiation positions, based on detection values of the first, second, third, and fourth scattered light.
