| titleOfInvention | A kind of method to improve the filtration speed of filter material |
| abstract | The invention discloses a method for improving the filtration speed of a filter material, which comprises the following steps: 1) firstly adding a strong oxidant gas into sewage to oxidatively decompose or/and crush water-soluble polymers or/and polymer residues in the sewage; In order to enhance the ability of sewage to pass through the filter material; 2) Then filter the sewage with the filter material, so that the sewage can be re-injected. 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. |
