Method for realizing rapid startup of denitrification biofilter |
| abstract |
A method for achieving rapid startup of a denitrification biofilter tank, which belongs to the technical field of biofilm sewage treatment. The specific steps are: 1. selecting heterotrophic denitrification or mixotrophic denitrification to treat influent sewage; 2. when the heterotrophic denitrification is used, pretreating the filter material with sodium carboxymethyl cellulose solution and then adding rhamnolipid after the introduction of sewage until the biofilter tank system starts successfully; 3. when the mixotrophic denitrification method is used, the filter tank is inoculated after the introduction of sewage, and the rhamnolipid is added thereto and is changed to sulfur source after operation for a while until startup is complete. The invention solves the problem that the denitrification biofilter tank in the sewage treatment is particularly slow in the mixotrophic state, and has a good application prospect. |
