深井曝气技术处理炼油废水工程实例

Engineering Example of Refinery Wastewater Treatment by Deep-Shaft Aeration Technology

通过对炼油废水水质特性的分析,采用两级隔油+两级气浮+缺氧+深井曝气组合工艺处理该废水。工程实践表明:该组合工艺能有效处理炼油废水,出水水质符合当地污水综合排放标准排入污水处理厂标准,且抗冲击负荷能力强。

Based on the analysis of the characteristics of refinery wastewater, a combined process with two-stage oil separation, twostage flotation, anoxie reaction, and deep-shaft aeration is used to treat the wastewater. The results of the engineering example show that the combined process is effective in removing contaminants from refinery wastewater, and water quality of the effluent meets local wastewater discharge standard for discharging wastewater into sewage treatment plants. This combined process also has strong resistance to shock loads.
