Drench sludge treatment process and treatment system
The invention discloses a sewer sludge treatment process and system, the sewer sludge treatment process comprises pretreatment, material classification, sand treatment, fuel forming and tail water treatment, and the sewer sludge treatment system comprises a pretreatment part, a material classification part, an aggregate treatment part, a sand treatment part, a fuel forming part and a tail water treatment part. The method comprises the following steps: separating heavy aggregate from a sand-gravel mixture in a pretreatment stage; in the material classification stage, the heavy aggregate, the first organic material and the gravel mixture are separated, and stone aggregate is obtained; in the sand material treatment stage, sand and stones are separated from the second organic material, and sand materials are obtained; in the fuel forming stage, the organic material is formed into fuel; in the tail water treatment stage, supernate is recycled to the pretreatment step, sewage is further treated, products in the whole treatment process are stone aggregate, sand and fuel, the products can be effectively utilized, incineration and landfill are not needed, and the influence on the ecological environment is small.
本发明公开了一种通沟污泥处理工艺及处理系统，通沟污泥处理工艺包括前处理、物料分类、砂料处理、燃料成型与尾水处理，通沟污泥处理系统包括前处理部、物料分类部、骨料处理部、砂料处理部、燃料成型部与尾水处理部。本发明中，在前处理阶段将重质骨料与砂石混合物分离；在物料分类阶段，将重质骨料、第一有机料、砂石混合物分离，得到石骨料；在砂料处理阶段，将砂石与第二有机料分离，得到砂料；在燃料成型阶段，将有机料成型为燃料；在尾水处理阶段，将上清液回用至前处理步骤，污水进行进一步处理，整个处理过程中的产物为石骨料、砂料与燃料，产物均能得到有效利用，并且无需焚烧、填埋，对生态环境的影响小。
