Urban sludge is a carbon material rich in organic matter. The preparation of activated carbon can not only solve the disposal problem of sludge, but also generate efficient and cheap adsorbent, which conforms to the scientific concept of circular economy and sustainable development.
wood based activated carbonIn this paper, the sludge of the municipal sewage plant was used as raw material, and the activated carbon was prepared by chemical activation method, and the adsorption of lead and cadmium was studied with it, so as to realize the use of waste for waste control. The conclusions are as follows:
activated carbon suppliers canada(1) According to the relevant national standards, the sludge of Liede Sewage Treatment Plant is mainly composed of volatile organic compounds, with a volatile content of 64.86%, which can be used as the main raw material for the preparation of activated carbon.(2) Without adding additives to the sludge, the concentration of sulfuric acid and zinc chloride is 4 mol
