Although the waste paper making technology has its own development advantages and good technological upgrading effect, it has received extensive attention and production, but because waste paper contains complex waste substances, It is necessary to remove this waste material through the action of chemical agents before pulping, and other chemical raw materials need to be added in this process, so there are many pollutants in the waste water formed after waste paper making. If the waste water is directly discharged without treatment, it will cause pollution of water resources., thereby destroying the natural ecological environment, it is difficult to play a protective role in environmental resources.
Waste paper making generally uses waste cardboard, waste newspapers, etc. as the main reproducing raw materials, which are used to produce whiteboard paper or cardboard paper and other products. The effect of paper recycling also forms more waste water. Wastewater mainly contains hemicellulose, lignin, inorganic fillers, dyes and other substances. These substances have a great impact on the pollution of water resources. Generally, the discharge of waste paper and papermaking wastewater comes from the deinking wastewater in the deinking process. and concentration process, etc., the formed wastewater contains many chemical pollution elements. If the related treatment of wastewater is not carried out, it is easy to cause the diffusion of pollutants and affect the water resources environment. It should be noted that the recycling of waste paper itself is a good process project, which can reduce the environmental pollution caused by waste paper, and can also reduce the damage to the natural ecological environment caused by plant papermaking, but the waste water formed in the process of papermaking from waste paper is not. It can affect the environment again and destroy the environment. If no effective measures are taken for wastewater treatment, the ecological benefits of waste paper recycling will cease to exist.
