Abstract：Thein-siturenovationofsewage plants facesthree majortechnicaldificulties：complex waterquality，limited space，andoutdatedfacilities.Complexwaterqualityisreflected inthediffcultyofcolaborative treatmentofmultiple polutants，theimpactofwaterqualityfluctuationsonthesystem，andthedificultyofremovingrecalcitrantorganic matter.

Basedonthis，this paperanalyzes thecauses of these technicaldificulties and proposes targeted measures toimprove the effectiveness of the transformation.
