Most of these hazadous waste liquids were experimentally treated in our laboratory. These works led to the following views : 1) Most of the waste liquids containing Hg passed the effluent standard by the treatment with the sulfide coagulating sedimentation method, but some of them needed the treatment with activated carbon or chelate resin. 2) In the case of oxidizing CN⁻, free CN⁻ could be easily decomposed but complexed CN⁻ could not be easily done. 3) Reduction of Cr (VI) with sodium sulfite was very effective but crystals of sodium sulfate prevented the desiccation of the resultant sludge., Article, 信州大学農学部紀要 18(2): 199-207(1981)}, pages = {199--207}, title = {信州大学農学部排水の処理について 第2報 有害物質含有排水の処理}, volume = {18}, year = {1981} }
