Abstract

The invention relates to a system and a process for treating water tank water of a printing plant and CTP plate flushing water to meet the discharge standard. The system comprises a flocculation reaction tank, first filtering equipment, electric flocculation equipment, second filtering equipment, electro-catalysis equipment and RO (Reverse Osmosis) equipment which are connected in sequence. Impurities can be effectively removed from water in the water tank treated by the system and the process disclosed by the invention, no new impurities are introduced, a large number of impurities mixed intowater such as industrial pollutants, heavy metals, bacteria and viruses are effectively and completely removed through the reverse osmosis membrane, the surface water discharge standard can be completely met, the whole treatment system can be automatically / manually controlled, and stable and reliable equipment operation is ensured.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a system and process for treating water tank water and CTP plate-washing water in a printing factory to meet discharge standards. Background technique [0002] The printing machine will generate a lot of heat when it is working. If it is not dissipated in time, it will cause damage to the printing machine. At present, the way to dissipate the heat generated by the printing machine is to connect the printing machine with the water tank, and the mixed solution in the water tank passes through The water inlet pipe enters the printing machine, and the heat exchange is carried out through the contact between the mixed solution and the printing machine to cool down the printing machine. On the other hand, the mixed solution is the necessary raw material for the printing machine to realize the printing function, that is, in the printing process, to The main componen...
