Problems solved by technology

However, this kind of deinking agent is only for traditional solvent-based inks, and has poor adsorption performance for water-based inks and stickies
Most of the deinking agents developed for water-soluble inks are imported products from abroad, with high cost and complicated process; biological enzymatic deinking technology has too high requirements on the operating environment, which is not conducive to large-scale promotion
The wastewater generated in the pulping process, the flocculants and adsorbents used in the treatment process have problems such as poor flocculation and adsorption effects, difficult removal of anion garbage, and poor COD removal effect
[0004] The sewage treatment agents in the prior art have low flocculation characteristics, and the solid waste formed after use is difficult to implement resource treatment; on the other hand, the recycling performance is poor

Abstract

The invention discloses a papermaking wastewater treatment agent. The papermaking wastewater treatment agent contains the following raw materials in parts by weight: 4-12 parts of bentonite, 3-9 parts of diatomite, 5-10 parts of aluminum hydroxide gel, 3-9 parts of sodium humate, 5-10 parts of sodium polyacrylate, 5-10 parts of polysorbate, 1-5 parts of aluminum sulfate, 4-12 parts of nano titanium dioxide, 1-5 parts of activated charcoal, 1-5 parts of sodium carbonate and 70-100 parts of water. The papermaking wastewater treatment agent has a good flocculation effect and a good adsorption effect, contaminants are effectively removed from sewage, and treated water can be recycled.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a papermaking wastewater treatment agent. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage. With the continuous development of industrial modernization, more and more industrial wastewater is discharged, which has a great impact on the environment and human life. If the sewage is not treated in time, not only It not only directly affects the quality of air and drinking water, but also indirectly affects the physical and mental health of human beings. [0003] With the development of the pulp and paper industry, it has become a new trend for waste paper to be reused for papermaking. Domestic paper mills mostly use alkaline deinking agent when deinking. However...
