Description
Technical Field
The utility model relates to an AO sewage treatment technology activated sludge emulsification device.
Background
The AO treatment process is a common process in rural sewage treatment, and main equipment comprises a combined nitrification device, a denitrification device and a precipitation device, wherein activated sludge in the precipitation device needs to flow back into the denitrification device, but in general, the activated sludge is aggregated into blocks, the surface area is lower, after the activated sludge flows back into the denitrification device, the rotating speed of a stirring device in the denitrification device is lower, the activated sludge cannot be well dispersed, and the activity of the activated sludge is low. And the activated sludge with more air directly flows back to the anaerobic denitrification device to be not beneficial to the growth of denitrifying bacteria, so that the denitrification efficiency is reduced.
In order to solve the problems, an activated sludge emulsifying device for an AO sewage treatment process is urgently needed to be developed, activated sludge which is refluxed into a denitrification device by a precipitation device is emulsified and dispersed, the surface area of the activated sludge is increased, air in the activated sludge is synchronously removed, and therefore the activity of the sludge is improved, and the denitrification efficiency of denitrifying bacteria is ensured.
SUMMERY OF THE UTILITY MODEL
In view of this, it is necessary to develop an activated sludge emulsifying device for the AO sewage treatment process to realize the emulsification of the activated sludge. The utility model discloses mainly carry out by following technical scheme: an activated sludge emulsifying device for an AO sewage treatment process comprises a nitrification device, a denitrification device, a sedimentation tank, a stirring paddle, an aeration device, a blower, a reflux device and an emulsifying device. The emulsifying device is positioned in the activated sludge reflux device, the activated sludge is emulsified by the emulsifying device before flowing back to the denitrification device, and the emulsifying device is a sealing structure and is provided with a vacuumizing device and can vacuumize the refluxed activated sludge.
Preferably, an emulsifying device is arranged on the activated sludge reflux device;
preferably, a high-speed emulsifying machine is arranged in the emulsifying device;
compared with the prior sewage AO treatment device, the utility model has the following characteristics:
1. the emulsification of the activated sludge is realized, the surface area is increased, and the sludge activity is improved;
