| titleOfInvention | A method of restoring the filtration speed of filter material |
| abstract | The invention discloses a method for recovering the filtration speed of a filter material, comprising the following steps: 1) firstly allowing sewage to enter an electrolysis system device for electrolysis, so as to oxidatively decompose or/and crush water-soluble polymers or/and polymer residues in the sewage 2) Then let the electrolyzed sewage enter the filter device to filter out the suspended solids and emulsified oil in the sewage, so that the sewage can be re-injected after reaching the standard. The invention can effectively solve the problem that water-soluble polymer and emulsified oil seriously affect the filtration speed and filtration performance of the filter material, can greatly reduce the dosage and operation cost of demulsification and dehydration and sewage treatment in the combined station, and can greatly reduce the sludge output; It has the advantages of easy implementation, safety and reliability, wide application and easy promotion. |
