- Abstract:
- With the expansion and transformation of refinery units of Sinopec Changling Branch, the influent quantity and concentration are much higher than the design value, and the influent organic matter load exceeds the sludge treatment capacity. Thus the biochemical treatment fails to achieve the expected effect, and the effluent quality of the second wastewater treatment plant cannot meet the Integrated Wastewater Discharge Standard(GB 8978-1996).Therefore, it is proposed to add the biological contact oxidation and internal recycle biological aeration filter (IRBAF) to the original oxidation ditch process, which can effectively realize the advanced treatment and ensure the effluent discharge standard.
