- 摘要:
- 中石化长岭分公司第二污水处理场因炼化装置的不断改造扩建，进水量和进水浓度远高于设计值，进水有机物负荷过高导致污泥超负荷运行，生化处理达不到预期效果，出水水质不能满足《污水综合排放标准》（GB 8978—1996）一级标准。因此提出在原有氧化沟流程上增设生化接触氧化和内循环曝气生物滤池处理工艺，改造后能有效实现深度处理，保证出水达标排放。
- 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.
