Further, the bottom of described mud-water separation chamber is conical structure, and its inclined-plane and horizontal plane angle are 40 °-45 °.
Further, the flow velocity of described nozzle ejection is 6-9m/s.
Further, describedly be arranged on three grades of web plates in the one-level flocculating chamber and reduce successively by order mesh-density from top to bottom.
Further, described baffle plate is the taper barrel structure, forms the sludge reflux seam between the bottom of the lower end of this baffle plate and mud-water separation chamber, and raw water flow is 1:1 to 1:2 with the ratio of sludge back flow quantity.
Further, described packing layer by elastic filler, fixedly the support of filler or soft-filler, fixedly filler is configured to.
Further, described braiding channel is annular.
Adopted technique scheme, beneficial effect of the present invention is: compared with prior art, the hydrolysis acidification pool based on granule sludge enhanced flocculation technique of the present invention has the following advantages:
1, the high speed by former water sprays into the returned sluge that the formation vacuum sucks bottom, mud-water separation chamber continuously, has avoided sludgd deposition, simultaneously without whipping appts, and without reflux pump, energy efficient;
2, the mud small part after mud-water separation is regularly got rid of as excess sludge, most of as the returned sluge recycle.During this device operational excellence, the granule sludge because the self-flocculation of microorganism cells forms, have the advantages such as content is many, activity is high, biomass is large, settling property is good than the granule sludge in common hydrolysis acidification pool;
3, backflow granule sludge and former water pollutant particle carry out contact flocculation, when in former water, small flco or de-steady particle contact with returned sluge, be refluxed the granule sludge layer and be retained down, the two particle diameter differs larger, and the backflow granule sludge has played the effect of strengthening water body particulate matter flocculation;
4, by three grades of web plates that density is different are set in the one-level flocculating chamber, increase the current turbulence, promote particle collision, and then form large-size particles, strengthening reaction zone biological treatment efficiency.
5, the filler in pond easily makes microorganism in its surface attachment, fixing, has increased greatly the microorganism total amount, guarantees that enough sludge concentrations participate in the biochemical degradation process, have improved the organic ability of microbiological deterioration.Simultaneously to the guarantor's mud that forms the granule sludge that settling property the is good effect that plays a good role.
