Description

technical field

[0001] The invention relates to a papermaking method and equipment, in particular to waste paper recycling and environmental protection equipment and a method. Background technique

[0002] my country is a country with a shortage of forest resources. At present, my country's annual demand for paper products is about 65 million tons, and it is still growing. It needs to consume a lot of wood and waste paper to regenerate to meet the demand for paper products. At present, my country's waste paper utilization rate About 38%. With the continuous development of society, the continuous expansion of demand for paper products, and the continuous reduction of resources, the status of my country's waste paper recycling industry will continue to improve, but the traditional waste paper recycling equipment and methods are not perfect enough. The utilization rate is low, the quality of recycled paper products is not high, and the wastewater pollution is serious. Since most ...
