混凝沉淀-厌氧-AB氧化沟工艺处理造纸废水

摘要

针对造纸废水SS、CODCr浓度高的特点,采用混凝沉淀-厌氧-AB氧化沟处理工艺,介绍了废水处理工艺流程、构筑物和设备的设计参数.工程运行结果表明,处理出水达到了设计要求,吨水直接运行费用为1.38元.%In view of the fact that papermaking wastewater contains high-concentration SS and CODCr, co-agulation sedimentation-anaerobic-AB oxidation ditch process was adopted for its treatment. The process flow, design parameters of structures and equipments of the said kind of wastewater treatment were introduced.The re-sults of the engineering operation showed that, the effluent water quality could meet the design requirement and the direct operating cost was 1.38 yuan/t.
