Description

A phosphorus removal device for urban domestic sewage

Technical Field

The utility model relates to the technical field of domestic sewage treatment, in particular to a phosphorus removal device for urban domestic sewage.

Background Art

After searching the Chinese patent CN207313255U, a municipal sewage denitrification and dephosphorization device was found. By adding a motor, a ball nut seat, a guide rod, an extrusion cartridge, a stirring blade and a screw, the design realizes the addition of reagents while stirring the sewage, thereby improving the working efficiency of the motor and the treatment effect. It solves the problem that the existing municipal sewage denitrification and dephosphorization devices usually separate the stirring and the addition of biological agents when treating sewage, thereby increasing the energy loss and reducing the treatment effect due to the inability to run synchronously.

However, the urban sewage denitrification and phosphorus removal device still has some shortcomings. After the reaction between the reagent and domestic sewage, the phosphorus will condense into agglomerates. However, the agglomerated phosphorus-containing mixture is easy to adhere to the inner wall of the sedimentation tank. If it is not removed, it will affect the subsequent phosphorus removal effect, resulting in poor removal effect of the total phosphorus concentration in the effluent.
