Papermaking wastewater is very harmful. Black water is the most harmful. It contains more than 90% of the total pollutant discharged from the papermaking industry. Because black water is alkaline, dark, smelly, and foam, it consumes large quantities of dissolved oxygen in water. It seriously pollute the water source and brings harm to the environment and human health.
The most serious environmental pollution of intermediate water is chlorine-containing wastewater produced in bleaching process, such as chlorinated bleaching wastewater, hypochlorite bleaching wastewater and so on. In addition, bleaching effluent contains dioxins, a highly toxic carcinogen, which also poses a serious threat to the ecological environment and human health.
