Problems solved by technology

[0003] Although the wastewater generated by the packaging and printing industry has a relatively small discharge, the water quality is complex, mainly ink wastewater and glue wastewater. The glue wastewater contains colloids, and the wastewater contains a large amount of colloids, which causes the BOD and COD of the wastewater to be too high. Poor biodegradability, ignoring the filtration of colloids will not be conducive to the subsequent biochemical treatment of wastewater, and the use of a large number of chemical agents for treatment will affect the economics of wastewater treatment

Embodiment Construction

[0034] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and To facilitate its practice, but not as a limitation of the invention.

[0035] See attached Figure 1-6 Shown, a kind of packaging and printing industry wastewater treatment method, its treatment method specifically comprises the following steps:

[0036] S1. Filtration of suspended impurities: filter the suspended impurities in the wastewater produced by packaging and printing production;

[0037] S2. Colloidal filtration: further filter the colloidal waste water that has been filtered of suspended impurities in step S1;

[0038] S3, waste water adjustment: pass the waste water that has completed colloid filtration in step S2 int...

Abstract

The invention relates to a packaging printing industrial wastewater treatment method. An adopted device comprises a filter frame, a filter plate horizontally and slidably mounted in the filter frame,a pair of extrusion roller sets rotatably mounted in the filter frame, a reciprocating motion driving mechanism mounted on the filter frame and a pair of scraping roller mechanisms mounted on the filter frame, and the reciprocating motion driving mechanism can drive the filter plate to horizontally reciprocate. The device is mainly used in the packaging printing industrial wastewater treatment method, is mainly used for filtering colloids in a kind of slurry glue wastewater generated in the packaging and printing industry, the biodegradability of the wastewater can be improved by filtering thecolloids through the device, the subsequent wastewater treatment process can be easily carried out, the input amount of chemical treatment agents can be reduced by filtering through a physical method, and the wastewater treatment economy is improved.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, and specifically proposes a method for treating packaging and printing industrial wastewater. Background technique [0002] Compared with industrial production such as papermaking and chemical production, which will generate a large amount of industrial wastewater, the industrial wastewater generated in the packaging and printing industrial production process is relatively small, and enterprises often ignore wastewater treatment; as environmental protection requirements become more and more stringent, the country Relevant laws and regulations are perfect, and packaging and printing companies have to start paying attention to the treatment of production wastewater in order to meet the standards required by the state for discharge. [0003] Although the wastewater generated by the packaging and printing industry has a relatively small discharge, the water quality is complex,...
