Preparation of activated carbon from sludge

Using the biochemical sludge and excess sludge of a sewage plant as raw materials, activated carbon is prepared by the zinc chloride activation method

Table 4-32 Physical and chemical properties of sludge

In order to obtain a qualified carbon-containing adsorbent, the sludge needs to be modified and activated

S1, G1, G2, and G3 were used to prepare activated carbon under the same process conditions (corresponding numbers are S1 active, G1 active, G2 active, G3 active), and its iodine value was determined.
