Pulp and paper wastewater is a type of pollutant that contains a large amount of organic and inorganic matter and microorganisms.These fungi can produce a large amount of organic acids, reduce the pH level of the wastewater, and produce various toxic substances, thereby polluting the environment .Bacteria in pulp and paper wastewater primarily include Bacillus, Proteus, anaerobic bacteria, Escherichia aerogenes, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, and Vibrio cholerae et al. These bacteria are highly active and can decompose organic matter to produce pollutants.Pulp and paper wastewater may contain many viruses, which can enter the human body through wastewater, causing infectious diseases and health hazards .In addition to bacteria, pulp and paper wastewater contains several fungi, such as yeast.

Pulp and paper wastewater is a type of pollutant that contains a large amount of organic and inorganic matter and microorganisms. Microbial pollution characteristics referto the polluting biological substances present in pulp and paper wastewater as well as the type, quantity, and activity of these biological substances Bacteria, fungi, and viruses are the most common microorganisms found in pulp and paper wastewater, with bacteria being the most abundant, followed by fungi, and viruses being the least abundant. Bacteria in pulp and paper wastewater primarily include Bacillus, Proteus, anaerobic bacteria, Escherichia aerogenes, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, and Vibrio cholerae et al. These bacteria are highly active and can decompose organic matter to produce pollutants. In addition to bacteria, pulp and paper wastewater contains several fungi, such as yeast. Yeast can generate a large amount of heat through reproduction, thereby affecting the temperature of the wastewater; it can also metabolize harmful toxins, causing pollution of the environment .Further, the wastewater contains several other fungi, primarily including various molds and mold spores. These fungi can produce a large amount of organic acids, reduce the pH level of the wastewater, and produce various toxic substances, thereby polluting the environment . Pulp and paper wastewater may contain many viruses, which can enter the human body through wastewater, causing infectious diseases and health hazards .
