Such wastewater contains suspended solids such as wood chips and wood powder, natural organic matter such as cellulose and lignin, and chemical substances such as preservatives, adhesives, and coloring agents used in the processing process. Some wastewater also contains heavy metal ions such as copper and zinc, and has complex composition and high pollutant concentration. If not effectively treated before discharge, it will cause serious pollution to the water ecological environment, destroy the habitat of aquatic organisms, and even affect human health through the food chain.
