Embodiment 1

[0032] A sludge filter press dewatering process, the process steps are as follows:

[0033] Step 1: Pre-inspection: Check in advance whether the feed pipe is unobstructed, and make necessary dredges at both ends of the pipe; check whether the filter cloth is damaged; whether the number of filter plates meets the regulations, and it is forbidden to use less than the specified number of filter plates Start work;

[0034] Step 2: Start-up inspection: Check whether the mortar pump, motor and other connecting parts are loose before starting the start-up, and verify the function of the mortar pump and motor. It needs to be idling for 10 minutes to check whether the flexibility and lubrication are in place; whether the hydraulic system is working normally and whether the pressure gauge is sensitive;

[0035]Step 3: Filter cloth combination: select the diaphragm filter cloth, the filter cloth must be installed flat, and no folding is allowed to prevent damage to the filter plate fram...

Embodiment 2

[0044] A sludge filter press dewatering process, the process steps are as follows:

[0045] Step 1: Pre-inspection: Check in advance whether the feed pipe is unobstructed, and make necessary dredges at both ends of the pipe; check whether the filter cloth is damaged; whether the number of filter plates meets the regulations, and it is forbidden to use less than the specified number of filter plates Start work;

[0046] Step 2: Start-up inspection: Check whether the mortar pump, motor and other connecting parts are loose before starting the start-up, and verify the function of the mortar pump and motor. It needs to be idling for 15 minutes, whether the flexibility and lubrication are in place; whether the hydraulic system is working normally, whether the pressure gauge is sensitive;

[0047] Step 3: Filter cloth combination: select the diaphragm filter cloth, the filter cloth must be installed flat, and no folding is allowed to prevent damage to the filter plate frame and leak...

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...
