Status Analysis on Construction and Operational Effectiveness of Municipal Wastewater Treatment Plants in Guangxi

Abstract:

In “Eleventh Five-Year” period, Guangxi has vigorously promoted the construction of municipal wastewater treatment plants. The statistics about construction scale shows that most of sewage treatment plants are small-scale. The main processes adopted in the plants are Oxidation ditch(OD), A²/O and SBR and its improved processes. The loading rate is generally low. COD and BOD removal effect are 78% and 87%. In scale of below 2×104m³/d, 2-5×104m³/d,5-10×104m³/d and more than 10×104m³/d, the costs of Diatomite, Oxidation ditch(OD), Oxidation ditch(OD), A²/O processes are relatively provincial, respectively. Meanwhile, the running costs of sewage treatment plants are mainly affected by the scale of construction and loading rate.
