摘要: 为了提升生产活动产生的某有机废弃物的资源化利用率,针对其产量大、分布分散 及处理后产生的高浓度沼液与厂区污水中 SS、COD、BOD、氨氮含量高的问题,进行了基于预处 理+IC 厌氧反应器+除氨氮池+两级 A/O 池+生物接触氧化组合工艺的有机废水处理技术研究。 研究结果表明:在稳定运行状态下,该反应器出水 COD 浓度为 2 000 mg/L,COD 去除率达到 88.2%, 所产气体中甲烷含量稳定在 59.5% 左右;该废水处理系统整体运行效果良好,该组合工艺可实现有 机污染物的有效降解与甲烷的稳定产出,能为有机废弃物资源化处理及后续废水处置提供有效技 术路径。

Abstract: In order to improve the resource utilization rate of an organic waste produced by produc⁃ tion activities,aiming at the problems of large output,scattered distribution and high content of SS, COD,BOD and ammonia nitrogen in high concentration biogas slurry after treatment and plant sewage, the organic wastewater treatment technology based on pretreatment + IC anaerobic reactor + ammonia nitro⁃ gen removal tank + two-stage A/O tank + biological contact oxidation combined process is studied.The re⁃ sults show that the effluent COD concentration of the reactor is 2 000 mg/L,the COD removal rate reaches 88.2%,and the methane content in the produced gas is stable at about 59.5% under stable operation.The overall operation effect of the wastewater treatment system is good. The combined process can realize the ef⁃ fective degradation of organic pollutants and the stable output of methane,which can provide an effective technical path for the resource treatment of organic waste and subsequent wastewater treatment.
