    摘要: The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions; a photocatalyst adapted to be brought into contact with the liquid in the first section; and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions. The photocatalyst may be at least one metal oxide including titanium and a metal having an electronegativity lower than that of titanium. In this case, it is possible to omit pH adjustments of the liquid before and after the photocatalytic reaction.

    摘要: An industrial waste management facility (IWMF) for disposing of spent potlining includes a co-current gas-fired rotary kiln for containing a molten pool of spent potlining throughout the entire length of the rotary kiln from the inlet to the outlet, an ash quencher and cooler for receiving molten residue from the discharge end of the rotary kiln, a secondary combustion chamber, and a down-draft transition chamber for channeling discharge gases from the rotary kiln to the secondary combustion chamber. Pneumatic injection slingers feed and distribute spent potlining into the inlet end of the rotary kiln. A discharge dam provides a predetermined average depth of molten bath material in the rotary kiln over its entire length. A blended ratio of comminuted materials injected through the pneumatic injection slinger feeder is adjusted and controlled in response to signals received from a radiative optical kiln bath temperature measurement system. The IWMF recovers fluorides from discharge gases exiting the secondary combustion chamber, recycles the fluorides to the molten bath or pool of the rotary kiln, and collects and withdraws glass frit residue from the ash quencher and cooler.
