摘要
结合大同某煤矿生活污水水量及水质特点,选用"A/O生物接触氧化+穿孔旋流絮凝+斜管沉淀+活性砂过滤"工艺对污水厂进行扩容升级改造。实践表明主要构筑物设计参数及工艺选择合理、科学,较好符合了工程实际。实际出水水质满足并优于设计要求的《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。
Based on the water quality and water quantity characteristics of a coal mine sewage in Datong,A combined treatment process including A/O biological contact oxidation,perforated vortex flocculation tank,inclined tube sedimentation,active sand filter was used for expansion and upgrading of sewage plant.The practice showed that the design parameters of the main structures and treatment process were reasonable and scientific,and conformed to reality.The actual effluent quality could meet or surpass class A standard of the Discharge Standard of Pollutants for Municipal Wastewater(GB18918-2002).
