Embodiment Construction

[0033] The following is attached Figure 1-5 The application is described in further detail.

[0034] The embodiment of the present application discloses a sewage treatment system made of decorative printing paper. refer to figure 1 A sewage treatment system made of decorative printing paper includes a filter tower and a filter tank, the filter tower is connected with a water inlet pipe and a drain pipe 13, the water inlet pipe is connected with a sewage source, and the drain pipe 13 is connected with the filter tank. The printing sewage enters the filter tower from the water inlet pipe, and performs the first filtration in the filter tower to filter out the large particles in the sewage, and the sewage filtered for the first time is discharged to the filter pool through the drain pipe 13 for the second filtration , the second filtration filters out the fine particles in the sewage, and the sewage filtered twice is then passed on to the next treatment process.

Description

technical field [0001] The invention relates to the field of printing sewage treatment, in particular to a sewage treatment system made of decorative printing paper. Background technique [0002] Decorative printing paper is widely used for decoration, outdoor advertising, etc. because it can print exquisite textures. The materials of different printing papers can be cardboard, metal sheet, and plastic sheet. Due to the need for mass production, it is necessary to The raw materials are processed, and then printed and painted. In the process of processing and printing, printing sewage will be generated, and the printing sewage needs to be treated to meet the standard before it can be discharged. [0003] The current treatment process for printing sewage is as follows: the printing sewage is naturally precipitated to precipitate the dirt in the sewage. After the supernatant is filtered and purified, it is concentrated and solid-liquid separated to complete the treatment of th...
