Photographic waste solution treating kit
专利汇可以提供Photographic waste solution treating kit专利检索，专利查询，专利分析的服务。并且PURPOSE:To automatically reduce the chemical oxygen demand (COD) of the photographic waste soln. to zero, and to drain it to a river or sewerage by preparing peroxosulfate capable of reducing COD of the waste soln. substantially to zero in advance and mixing a necessary amt. of it into the soln. CONSTITUTION:A color negative film 102 is conveyed from the magazine fixed section 101 of the automatic developing machine 104 of a color photographic sensitive material successively to the color developing bath 106 of the main body of the machine 104, the bleach fixing baths 107, 108, 109 and the fixing bath 110 to automatically develop it. This developed film 102 is dried in the drying chamber 111, lead out to the outlet 112 of the main body 104, and these control of operations and the temps. of the baths 106-110 are performed at a control system equipment chamber 113. The waste solns. from drain pipes 114A-114C are received in a waste soln. tank 115, and a necessary amt. of peroxosulfate enough to reducing COD of the waste soln. in the tank 115 substantially to zero is prepared in advance and it is mixed into the waste soln. to automatically reduce COD substantially to zero.，下面是Photographic waste solution treating kit专利的具体信息内容。
