摘要
针对油气站场生活污水水量小、间歇排水、水量波动大等特点,采用耦合物化、生化和生态处理的恒水位厌氧-缺氧/竖向脉冲滴滤/介质滤床的污水处理工艺,以干湿交替运行方式实现站场的污水处理。以东营市鲁源管理站生活污水处理为例,该工程污水处理量为5.0 m^(3)/d,恒水位厌氧-缺氧池的水力停留时间为1.2 d;脉冲滴滤池水力负荷为6.3 m^(3)/(m^(2)·d);介质滤床水力负荷为0.5 m^(3)/(m^(2)·d)。经过启动驯化和冬季过渡阶段,系统稳定运行,原水COD、NH_(4)^(+)-N、TN、TP的平均浓度分别为214.2、42.71、62.23、4.42 mg/L,出水相应指标的平均浓度分别为31.9、4.29、10.74、0.53 mg/L,平均去除率分别为85.1%、90.0%、82.7%和88.0%,满足《城市污水再生利用城市杂用水水质》(GB/T18920—2020)的绿化用水标准和《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。
Focused on the characteristics of little domestic sewage,intermittent drainage,and significant water consumption fluctuation in oil and gas station,the sewage treatment process of constant water level anaerobic-anoxic/vertical pulse trickling filter/medium filter bed coupled with physicochemical biochemical ecological treatment is adopted to treat the station’s sewage by alternating dry-wet operation.The sewage treatment capacity of the Luyuan management station of Dongying is 5.0 m^(3)/d.The hydraulic retention time of constant water level anaerobic-anoxic is 1.2 days.The hydraulic load of a pulse trickling filter is 6.3 m^(3)/(m^(2)·d)and that of the filter bed is 0.5 m^(3)/(m^(2)·d).After the start-up domestication and winter transition stage,the system ran stably.The average influent concentrations of COD,NH_(4)^(+)-N,TN and TP were 214.2 mg/L,42.71 mg/L,62.23 mg/L and 4.42 mg/L,respectively.The average effluent concentrations of COD,NH_(4)^(+)-N,TN and TP were 31.9 mg/L,4.29 mg/L,10.74 mg/L and 0.53 mg/L,respectively,which meet the landscaping criteria in The Reuse of Urban Recycling Water—Water Quality Standard for Urban Miscellaneous Use(GB/T 18920-2020)and first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The average removal rates were 85.1%,90.0%,82.7%and 88.0%,respectively.
