3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Photosensitive material washing waste liquid developingwasteliquidofphotosensitivematerial
Waste water and waste liquid generated by the photographic material during development, bleaching, fixing, etc.
4 photographic materials washing industry waste liquid types
4.1 Waste developer
Waste developer includes waste developer, protectant, accelerator, fog inhibitor, and other special additives. The main component is waste
Discarded developer, wherein the main component of the black and white developer is methylamine phenol and hydroquinone; the main component of the color developing agent is p-phenylenediamine
derivative. Chemical oxygen demand (CODCr) concentration. 6 × 103 mg/L ~ 6 × 104 mg/L.
4.2 Waste Fixer
After the photosensitive material is exposed and developed, the waste liquid generated in the process of removing the unexposed undeveloped silver halide from the emulsion by the fixing solution. Waste
The main component of the fixing solution is a discarded fixer, as well as a waste of a protective agent, a neutralizing agent, and a hardener. Silver (Ag) concentration. 1000mg/L~
12000mg/L (mainly in the form of silver thiosulfate complex, followed by ferrous iron diamine tetraacetate), chemical oxygen demand concentration.
5 × 104 mg/L ~ 9 × 104 mg/L.
4.3 Waste bleach
The coloring material is oxidized during the process of oxidizing the metal silver in the emulsion to convert the metal silver into silver ions, and by means of halogen
a compound (usually potassium bromide or ammonium bromide) that is re-halogenated to silver bromide, converted to a soluble silver complex, and removed from the emulsion.
