We all know that the sludge to be treated quickly, can ensure the health of the people living here, we have to figure out those toxic sludge harmful ingredients, see if you can find a solution, blindly burning landfill After all, is not the answer. Must be completely eradicated. Paper sludge by ingredient distinction can be divided into biological sludge, Recovery Nai and deinking sludge. Wastewater generated a lot of sediment, these precipitates was to become paper sludge, which contains mainly fine fibers, lignin and derivatives and some other organic matter. Recovery from the Recovery Workshop Nai Nai recovery section, is harsh reaction product, intraoperative precipitated calcium carbonate, mainly arising from the use of pulp and paper mills. Deinking sludge produced in the deinking process. In today's precious natural resources, many countries make full use of secondary resources, using waste paper as raw materials, mainly bound to generate a lot of de-inking sludge. Deinking sludge composition is very complicated, mainly cellulose fibers and paper in the original packing box paint, in addition to a number of short fibers, grits, and most of the humor particles.
