Description
Technical field
The utility model relates to a kind of percolate SBR and Anammox combined denitrification device, belongs to low-carbon and nitrogen (C/N) than high-concentration ammonia nitrogenous wastewater bio-denitrification technology field, is applicable to the biological denitrificaion of the high ammonia-nitrogen wastewater of low C/N ratios such as percolate in late period.
Background technology
In recent years, along with the continuous increase of MSW output, landfill method became most widely used in the world processing and method of disposal gradually.The percolate that landfill produces because of have complicated component, water quality and quantity variation greatly, organism and water quality characteristicses such as ammonia nitrogen concentration height, the imbalance of microbial nutrition element ratio, make it be treated as in the international coverage one of unsolved difficult problem still.Adopt the processing percolate that single treatment technology often can not economical and efficient, need the process integration of different characteristics to use.The famine of organic carbon source is the barrier that late period, the percolate nitric efficiency can't improve, and adds the expense that organic carbon source can significantly increase sewage water denitrification.Therefore, need to propose the apparatus and method of more efficiently denitrogenation.
Bio-denitrifying sewage is through nitrated with NH
4 +-N is converted into NO
3 --N passes through denitrification again with NO
