    • PURPOSE: A treatment method and a treatment apparatus for performing the decomposition treatment of wastewater containing TMAH (tetramethylammonium hydroxide) etc., and ammonia and hydrogen peroxide by a series of treatment processes are provided. CONSTITUTION: The method for treating the wastewater containing TMAH etc., ammonia and hydrogen peroxide comprises a hydrogen peroxide decomposing step of decomposing the hydrogen peroxide in the wastewater; a diffusing step of diffusing the ammonia from the H2O2 removed wastewater; a thickening step of obtaining TMAH-containing concentrate by thickening the wastewater after the diffusion of the ammonia; a gasifying step of gasifying the concentrate; and a decomposing step of decomposing the gas obtained in the gasifying step and the diffused ammonia-containing gas using a catalyst. The apparatus for treating the wastewater containing TMAH etc., ammonia and hydrogen peroxide comprises a hydrogen peroxide decomposing section(51) for decomposing the hydrogen peroxide in the wastewater; a diffusing column(26) for diffusing the ammonia from the H2O2 removed wastewater; a thickening section(56) for obtaining TMAH-containing concentrate by thickening the wastewater after the diffusion of the ammonia; a gasifier(76) for gasifying the concentrate; and a catalyst reactor(18) for decomposing the gas obtained in the gasifier and the diffused ammonia-containing gas using a catalyst.
    • 目的:提供一种处理方法和处理装置,用于通过一系列处理方法对含有TMAH(四甲基氢氧化铵)等的废水和氨和过氧化氢进行分解处理。 构成:用于处理含有TMAH等的废水,氨和过氧化氢的方法包括在废水中分解过氧化氢的过氧化氢分解步骤; 扩散步骤,从H2O2去除的废水中扩散氨; 通过在氨扩散后增加废水来获得含TMAH的浓缩物的增稠步骤; 使精矿气化的气化工序; 以及使用催化剂分解气化工序中得到的气体和扩散的含氨气体的分解工序。 用于处理含有TMAH等的废水,氨和过氧化氢的设备包括用于分解废水中的过氧化氢的过氧化氢分解部分(51) 用于从去除H 2 O 2的废水中扩散氨的扩散塔(26); 用于通过在氨扩散后增加废水来获得含TMAH的浓缩物的增稠部分(56) 用于气化所述浓缩物的气化器(76) 和催化剂反应器(18),用于使用催化剂分解在气化器中获得的气体和扩散的含氨气体。
