摘要
Abstract
The food waste leachate from a district of Shanghai contains a large amount of oil and suspended solids,and also obtains high concentration of organic matter,ammonia and total phosphorus,thus belonging to refractory organic wastewater.In this project,the combined process of pretreatment-anaerobic treatment-magnesium ammonium phosphate(MAP)reactor-biological denitrification was used to treat food waste leachate,and the daily treatment capacity reach 100 m3/d.The three-phase separator is applied in pretreatment to separate scum and grease.Two-stage anaerobic treatment process is utilized to enhance degradation and removal of organic matter.The combined treatment process had a strong resistance to impact load of influent wastewater.The project operation shows that the average CODCr mass concentration of the effluent from the combined treatment process is 245 mg/L,the ammonia nitrogen mass concentration is 6 mg/L,the total nitrogen mass concentration is 40 mg/L,and the total phosphorus mass concentration is 4 mg/L,which meets the three-level management standard of the Shanghai Integrated Sewage Discharge Standard(DB 31/199-2018).The cost for each ton of wastewater treatment is only 134.57 yuan,which indicates that the combined process of pretreatment-anaerobic treatment-MAP-biological denitrification is an effective method for treating food waste leachate.关键词
