Total-content-standard deep treatment technical technology, method and system for landfill leachate capable of not generating concentrated solution

The invention provides a total-content-standard deep treatment technical technology and method for a landfill leachate capable of not generating a concentrated solution. The technology comprises the steps of sulphur autotrophic denitrification and efficient adsorption. According to sulphur autotrophic denitrification, sulphur autotrophic denitrification bacteria are used for deep denitrification on a biochemical effluent of the landfill leachate capable of not generating the concentrated solution; according to the efficient adsorption, refractory organic substances and chroma in the effluent in the sulphur autotrophic denitrification step are subjected to adsorption removal, partial organic nitrogen is removed, and finally standard discharging of the effluent is achieved. The technology iseasy to implement, capable of achieving convenient operation and management, low in operation cost and suitable for engineering application, and total-content-standard deep treatment for the leachateis achieved. 本发明提出一种不产浓缩液
