    • PROBLEM TO BE SOLVED: To provide a neutral electropolishing liquid composition for descaling a stainless steel surface, which inhibits the breakage of a passive film in alternating-current electrolysis, and the production of harmful hexavalent chromium in direct-current electrolysis, which have been conventionally considered to be problems in electrolytic polishing for removing stains such as weld burning and rust on the stainless steel surface, through electrolysis; and a treatment method for the stainless steel surface.
      SOLUTION: The neutral electropolishing liquid composition for descaling the stainless steel surface indispensably includes: one or more salts among an alkali metal salt, an alkaline earth metal salt and an ammonium salt of any of sulfuric acid, pyrosulfuric acid, sulfurous acid and thiosulfuric acid; and one or more salts of amino-polycarboxylic-acid-based chelating agents.

    • PROBLEM TO BE SOLVED: To provide a method of and a device for treating the fouling of an aromatic halide by which a fibrous material such as paper, cloth or a woody material adhered or impregnated with the aromatic halide, especially a polychlorinated biphenyl(PCB) or a polychlorinated phenol(PCP) is made harmless. SOLUTION: The method for treating deposits of an aromatic halide comprises the first step to disaggregate the fouling, the aromatic halide or an oil containing the aromatic halide which adheres to or is impregnated into a fibrous material such as paper, cloth or a woody material, the second step to emulsify the obtained disaggregation solution with the help of an emulsifier, the third step to add quick lime to the obtained emulsion and stir/mix these materials and the fourth step to heat the mixture at 150 to 300 deg.C.
    • 要解决的问题:提供一种用于处理芳族卤化物的结垢的方法和装置,通过该方法和装置,芳族卤化物,诸如纸,布或木质材料的纤维材料通过芳族卤化物,特别是多氯联苯(PCB) 或多氯酚(PCP)是无害的。 解决方案:用于处理芳族卤化物沉积物的方法包括将结垢,芳族卤化物或含有芳族卤化物的油分散在第一步骤中,所述芳烃卤化物粘附或浸渍到纤维材料如纸,布或木质材料中, 在乳化剂的帮助下乳化所得解聚溶液的第二步骤,第三步是向所得乳液中加入生石灰并搅拌/混合这些物质,第四步在150至300℃加热混合物。
