Abstract

The invention discloses a sludge filter-pressing dehydration process in the technical field of sludge treatment. The process comprises the following steps: step 1, early-stage inspection; 2, starting-up check; 3, filter pressing cloth combination; 4, using of a diaphragm filter press; 5, adding of a medicament; 6, using of a filter press; 7, sludge treatment; and 8, sludge transfer. According to the sludge filter-pressing dehydration process, the process steps of sludge filter-pressing dehydration are optimized, so that the efficiency of the sludge filter-pressing dehydration process is improved, the cleaning capability on the diaphragm type filter-pressing cloth is good, the damage probability of the diaphragm type filter-pressing cloth is reduced, and the service life of sludge filter-pressing dehydration equipment is ensured; and the medicament is added in the sludge filter-pressing dehydration process, so that the purposes of dewatering and cleaning in the sludge filter-pressing dewatering process are effectively increased, the subsequent treatment process is simplified, and the safety of later sludge treatment is improved.

Description

technical field [0001] The invention discloses a sludge filter press dehydration process, and specifically belongs to the technical field of sludge treatment. Background technique [0002] Sludge is a solid sedimentary substance produced in the process of water and sewage treatment. Sludge treatment is used in the process of sludge treatment. Sludge treatment is to concentrate, condition, dehydrate, stabilize, dry or Incineration and other reduction, stabilization and harmless processing. [0003] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. [0004] Sludge treatment facilities include sludge filter press devices. For example, filter presses, as a mature dehydration equ...
