Precipitation device for production of phosphorus removal agent prepared from combined-state phosphorus-accumulating bacteria

Abstract

The utility model relates to a precipitation device for producing a phosphorus removal agent by adopting combined phosphorus-accumulating bacteria, and effectively solves the problems that most of the existing precipitation devices for producing the phosphorus removal agent take out precipitation liquid from the top ends of the precipitation devices in the extraction process of the precipitation liquid of the phosphorus removal agent; in this way, the whole liquid is easily stirred during extraction, so that the precipitation liquid and the precipitate are fused again, and secondary precipitation work needs to be carried out; according to the precipitation device for production of the phosphorus removal agent prepared by adopting the combined-state phosphorus-accumulating bacteria, through cooperative arrangement of a storage barrel and a first collection barrel, precipitates can be downwards pumped out by virtue of the first collection barrel after precipitation, so that the condition of secondary mixing between the precipitates and a precipitation solution is reduced, and workers can discharge the precipitation solution more conveniently for use; and through cooperative arrangement of the drainage mechanism and the precipitation barrel, floating objects at the top and upper-layer precipitation liquid can be directly drained outwards in the precipitation process, and the overall precipitation effect of the precipitation liquid is further guaranteed.
