Description

technical field

[0001] The invention relates to the field of water treatment, in particular to a papermaking wastewater advanced treatment device and a papermaking wastewater advanced treatment method. Background technique

[0002] According to the requirements of "Water Pollutant Discharge Standards for Pulp and Paper Industry" (GB3544-2008), since 2008, new pulp and paper enterprises will implement the standard "Table 2 Water Pollutant Discharge Limits for New Enterprises", such as paper industry wastewater Emission of COD shall be ≤80mg / L, and ammonia nitrogen shall be ≤8mg / L.

[0003] With the rapid development of the economy, the density of national land development is increasing, while the environmental carrying capacity is weakening day by day. As a key polluting industry, the paper industry has increasingly stringent environmental protection requirements. The paper industry implements "Table 3 Special discharge limits for water pollutants" The requirement is an inev...
