- 摘要:
- 采取微孔曝气氧化沟中试装配处置现实污水处置厂沉砂池出水，研究了中试装配在低温前提下实现启动的可行性和靠得住性。成果注解，中试装配抗冲击负荷能力较强，在低温前提下（13~18 ℃），节制好氧区DO浓度为0.5~1.0 mg/L，系统运转不变；实验后期，中试装配出水目标除TP外其余均知足《城镇污水处置厂污染物排放尺度》一级A尺度要求。是以，在低温前提下中试装配可经由过程下降系统曝气量实现启动。阐发了除磷结果欠安的缘由，首要与排泥不纪律、接种污泥除磷能力较差、回流污泥中含有硝态氮等相关。
- Abstract:
- A pilot-scale microporous aeration oxidation ditch was applied to treat the effluent from a grit chamber of a wastewater treatment plant, and the feasibility and reliability of starting up the pilot plant at low temperature were investigated. The pilot plant had strong shock load resistance, and the system operated stably at low temperatures between 13 ℃ to 18 ℃ when maintaining dissolved oxygen concentration between 0.5 mg/L and 1.0 mg/L. Except TP, the effluent quality of the pilot plant reached the first level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant during the late period of the test. The pilot plant could be started up by reducing the aeration rate at low temperature. The reason for poor phosphorus removal was mainly related to irregular sludge discharge，poor phosphorus removal capacity of inoculated sludge and nitrate in the reflux sludge.
