Problems solved by technology

However, this method can only play a mitigating role, and cannot fundamentally eliminate the pollution of heavy metals to the soil. With the change of environmental conditions and the passage of time, heavy metals will still enter the environment and cause pollution.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a novel resource-based sludge treatment system and treatment method. Background technique [0002] With the improvement of sewage treatment and discharge standards in recent years, the traditional biochemical treatment process of sewage plants has been unable to meet the discharge requirements of total phosphorus. At the same time, considering the cost factor, most water plants use chemical phosphorus removal methods and add a large amount of iron to the treatment process. Salt or aluminum salt flocculants mix a large amount of inorganic metal salts into the activated sludge of water plants, thereby reducing the organic components in the mixed sludge, and finally lead to the fact that inorganic salts account for dry sewage in the sludge of sewage plants. 35% or even more of the sludge component brings many problems to the subsequent treatment and disposal of the sludge. ...
