Detailed description of the invention

Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.

As shown in Figure 1, a kind of bioflocculation pond, comprises pond body 10, cylindrical shell 3, kuppe 7, aerationPipe 4, rack 2 and bioflocculation layer 6, described cylindrical shell 3 stretches into the interior position near bottom of pond body 10,Cylindrical shell 3 upper ends connect into the mouth of a river.

Kuppe 7 is connected in cylindrical shell 3 belows, and kuppe 7 belows are detachably provided with filter screen 8. Biological waddingSolidifying layer 6 is covered in pond body 10, and is positioned at around cylindrical shell 3, and aeration tube 4 is provided with and is no less than two,Aeration tube 4 is fixed on pond body 10 inwalls, and aeration tube 4 outlets are positioned at bioflocculation layer 6 below, forFor biological flocbed 6 oxygen supplys.

Rack 2 is fixed on pond body 10 inwalls, and is located near bottom, pond. On rack 2, be placed withAnaerobic bacteria layer, the sewage flowing out from cylindrical shell 3 belows, through anaerobic bacteria layer, is detested the organic matter in sewageThe decomposition of oxygen bacterium, metabolism, digestion.

The top of bioflocculation layer 6 is provided with silk screen 5, and bioflocculation layer 6 adheres to silk screen 5 times, Chi Ti10 are provided with delivery port 1 in silk screen 5 upper ends, and body 10 bottoms in pond are provided with sewage draining exit 9.

When use, sewage first passes through filter screen 8, tentatively filters; Then pass through anaerobic bacteria layer, make dirtOrganic matter in water is by anaerobic bacteria decomposition, metabolism, digestion; Pass through again bioflocculation layer 6, from water outletMouth 1 is discharged.

Above embodiment of the present utility model is had been described in detail, but that described content is only this practicality is newThe preferred embodiment of type, can not be considered to for limiting practical range of the present utility model. Fan Yiben practicalityEqualization variation and improvement etc. that novel application range is done, all should still belong to patent of the present utility model and containWithin lid scope.
