Developer solution can be used to use special distillation processing technology to deal with the developer, directly cured into slag, without any wastewater discharge. Not only can effectively deal with the problem of developing wastewater can not be discharged, but also can reduce the cost of enterprises.
The process: developer wastewater from the storage tank into the regulator box for water, water quality adjustment, to ensure the stability of the developer wastewater, for the subsequent process to provide the necessary conditions for the smooth running of the process. By the centrifugal pump will waste liquid into the developer curing treatment equipment, after special distillation of developer wastewater directly into the solid. This achieves the purpose of zero discharge of developer wastewater and also reduces the cost of developer treatment. p>According to the "National Hazardous Waste List", the waste developing solution and fixing solution generated in the printing industry and photo printing process, as well as the waste film and paper, all belong to the 16th ranked "photographic material wastes", and the concentration of its pollutants exceeds the national emission standards by hundreds of times, especially the high concentration of "Total silver", is the first category of pollutants that may cause cancer and teratogenicity.
Once discharged directly into the river through the sewers, it is extremely harmful to the human body and super polluting to the environment.
Related laboratory analysis shows that the use of these photographic materials after the waste, containing a large number of heavy metals and serious environmental pollution of organic matter, such as boric acid, hydroquinone, a variety of bromide and other harmful components, these chemicals are more stable, not easy to degrade naturally, improper storage and disposal or random discharge, will be a greater danger to the soil, water and human health.
