厌氧折流板调节池预处理垃圾转运站压滤液的中试研究

Per-treatment of transfer station wastewater by anaerobic baffled regulation pool: A pilot scale research

建立了中试规模的厌氧折流板调节池,用于转运站垃圾压滤液的现场预处理。转运站垃圾压滤液具有高有机污染物浓度、水质变化剧烈和pH值较低等特点,当进水COD浓度为50 000 mg/L～80 000 mg/L,厌氧折流板反应器能稳定实现出水COD=25 000 mg/L左右,总氮去除率30%～40%,总磷去除率70%,抗冲击能力和低pH值进水运行稳定性良好。厌氧折流板调节池发生酸化后,综合采用了多种措施加以调控。

A Pilot scale anaerobic baffled regulation pool was established at a transfer station.It was used for leachate per-treatment.Transfer station leachate has a high concentration of organic pollutants,severe variety of water quality and low pH.COD of anaerobic baffled reactor effluent can reach to about 25 000 mg/L stably while inflow COD was 50 000~80 000 mg/L.TN removal rate was 30%~40%,TP removal rate was 70%.Anaerobic baffled regulation pool has good impact resistance and operation stability under low pH.Integrated measures were taken after acidification.
