Description

Sewage treatment limit dephosphorization pool

Technical Field

The application relates to the technical field of sewage treatment, in particular to a sewage treatment limit dephosphorization pool.

Background

The limiting phosphorus removal means that the TP (total phosphorus in the water body) value in the water body is reduced to 0.05mg/L or below through a water treatment device and treatment operation. The water body after dephosphorization is discharged can not cause the outbreak of blue algae bloom, especially for sensitive water areas with weak pollutant carrying capacity, the TP value of the discharged water needs to meet the requirement, otherwise, the formation of a large amount of blue algae in the discharged water body can not be avoided.

When the existing limit dephosphorization is carried out, phosphorus in sewage is firstly captured and coated with flocculant polyaluminium chloride (PAC) to form flocculation, and then is mixed with coagulant aid Polyacrylamide (PAM) to form stable floccule particles, so that the phosphorus is removed.
