The invention provides a wastewater treatment technology and device for a guide belt type digital printing machine. The device comprises membrane equipment, a flocculation device and electro-catalysis oxidation equipment. The membrane equipment comprises a secure filter and a membrane assembly. An output port of the secure filter is connected with the membrane assembly. A concentrated liquid output port of the membrane assembly is connected with a liquid storage tank, a permeating liquid output port is connected with a cleaning water source, the liquid storage tank is connected with the electro-catalysis oxidation equipment, an output port of the electro-catalysis oxidation equipment is connected with the flocculation device, and a liquid output port of the flocculation device is connected with the membrane equipment. By means of the wastewater treatment technology and device for the guide belt type digital printing machine, 90% of primary wastewater generated by cleaning the guide belt type digital printing machine can be recycled, so that water resources are greatly saved, and the printing production cost is reduced. Meanwhile, less wastewater is discharged, and thus environment protection is facilitated.
Description
technical field [0001] The invention belongs to the field of printing and dyeing wastewater treatment, in particular to wastewater treatment of a belt-conducting digital printing machine. Background technique [0002] During digital printing, a clean web is the most important prerequisite for optimal adhesion of the fabric to the glue. At the same time, a clean guide belt prolongs its service life. In the prior art, the conduction band is mostly cleaned by washing with water. Therefore, in order to keep the conduction zone clean, a large amount of clean water is required for cleaning, which not only wastes water resources, but also pollutes the environment after cleaning. [0003] The existing printing and dyeing wastewater treatment methods are not perfect, the utilization rate of wastewater is low, and the purpose of recycling cannot be well achieved. Contents of the invention [0004] In view of this, the present invention aims to propose a belt-type digital printing...
