Abstract

The invention discloses a high-concentration printing ink waste water processing technology and belongs to the technical field of waste water processing in the printing field. The high-concentration printing ink waste water processing technology includes the following steps that ink waste water passes through a floatation tank and is mixed with life sewage through an adjusting pool, then the waste water goes through an anaerobic pool, a first-level aerobiotic pool and a second aerobiotic pool to be processed, undergoes sedimentation by a secondary sedimentation tank and undergoes solid-liquid separation. Sludge in the floating pool, the anaerobic pool and the secondary sedimentation tank is drained into a sludge concentration tower through a sludge pump. After the sludge is concentrated, a pneumatic membrane pump is used for pumping the sludge to a plate-and-frame filter press to be dewatered. Pressed and dried sludge cakes are cleaned manually and packaged. Filtered liquid flows back to the waste water adjusting pool. The high-concentration printing ink waste water processing technology is stable in technological processing effect, resistant to impact, low in consumption, efficient, convenient to manage and easy to maintain.

Description

technical field

[0001] The invention belongs to the technical field of wastewater treatment in the printing field, in particular to the treatment of high-COD, high-chroma, and refractory biodegradable wastewater generated during the production and use of high-concentration printing inks, and specifically a high-concentration printing ink wastewater treatment process. Background technique

[0002] In recent years, the ink industry has developed rapidly. The pigments used in inks usually have light resistance and heat resistance stability, acid resistance, alkali resistance, resistance to common oxidants, and have good tinting strength, hiding power and sublimation fastness. Commonly used phthalocyanine pigments have many types, bright color, strong tinting strength and good fastness, and are widely used in printing, coatings, inks, etc. In the printing production process, high-chroma ink wastewater will be generated, and the wastewater will be discharged intermittently. The w...
