Compared with prior art, it is an advantage of the current invention that:
The heavy metal sewage treatment equipment of the present invention, by putting into flocculation aid, magnetic agent etc. in sewage, utilizes a knockout drum,
That in sewage, heavy metal in dissolved state is changed into water-fast heavy metal compound by chemical reaction, then by filtering and
Separation makes precipitate remove from aqueous solution, solves the heavy metal harm to environment.The present invention isolated heavy metal compound energy
Heavy metal is isolated in enough recovery again.Present configuration is simple, and floor space is little, improves heavy metal removing rate in sewage, promotes
Discharge water reaches the surface water above standard of V class, decreases mud discharging, it is achieved continuous operation, automatization, installation be convenient,
Take up an area less, low cost.
