Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of power plant desulfurization sewage treatment equipment, including water inlet pipe 1, enters
Water pipe 1 connects intake pump 2, and intake pump 2 connects Aeration tank 3, and Aeration tank 3 connects desaturation pond 17, and upper end, desaturation pond 17 connects
Lime under agitation pond 4, is provided with agitating device in lime under agitation pond 4, upper end, lime under agitation pond 4 connects lime bin 5, desaturation pond 17
Connecting first stage precipitation tank 7, first stage precipitation tank 7 connects balancing tank 8, and balancing tank 8 connects mixing pit 10, and mixing pit 10 upper end connects to be had
Machine sulfur case 9, mixing pit 10 connects regulating reservoir 12, and regulating reservoir 12 connects acid solution case 11, and regulating reservoir 12 connects second-level settling pond 14, and two
Level sedimentation tank 14 upper end connects flocculant case 13, and second-level settling pond 14 connects waste liquid medium filter 15, waste liquid medium filter
15 side, upper ends connect balancing tank 8, first stage precipitation tank 7 and second-level settling pond 14 lower end and connect solid-liquid mixing pit by sludge pump 18
