Method for quickly removing COD from papermaking wastewater

1. Adsorption method:

The granular organic matter and chromaticity in sewage can be absorbed and treated by active adsorption materials such as activated carbon, macroporous resin, and bentonite.

It can be used as a pretreatment to reduce COD which is easier to handle.

1. Microbiology method:

Biological method is a wastewater treatment method that relies on microbial enzymes to oxidize or reduce organic molecules, destroy their unsaturated bonds and chromophores, and achieve the purpose of treatment.

1. Chemical method:

The oxidation effect of chemical agents is used to decompose organic matter. This method has high decomposition efficiency of organic matter and fast processing time. Generally, the agent is directly added to the water outlet for use, without changing the process, without adding equipment, without excessive tedious operation 2 pollution
