In this study, we have used the actual survey method of wastewater collection at station 3.1 and the analysis method of pollution parameters such as: COD, TSS, color to evaluate treatment efficiency of the system. The research results showed that the wastewater to the collection system from 134 companies and residential areas exceeded QCVN 40:2011/BTNMT, column B
The wastewater after treatment reaches QCVN 40:2011/BTNMT column A, but the concentration of pollutants is still high. In terms of treatment efficiency in each stage, the treatment efficiency of COD, TSS, color after going through the chemical and physical phase was 63,1%, 72,6%, 49,9% respectively
the treatment efficiency of COD, TSS, color after going through the aerobic biological stage was 76,2%, 92,7%, 34% respectively
the treatment efficiency of COD, TSS, color of the whole system was 91,1%, 91,1%, 67,2% respectively.
