Embodiment 1

[0031] Such as figure 1 As shown, this embodiment provides a denitrification device for landfill leachate, which is suitable for deep biochemical treatment of waste water with high ammonia nitrogen such as landfill leachate, biogas slurry, and feces supernatant, and has a wide range of applications.

[0032] Specifically, the denitrification equipment for landfill leachate includes a denitrification reactor, a nitrification reactor and an external ultrafiltration device 3 . The function of the denitrification reactor is to denitrify the landfill leachate, and its denitrification efficiency is relatively high. The function of the nitrification reactor is to carry out a short-range nitrification reaction on the landfill leachate. The function of the external ultrafiltration device 3 is to filter and transport the filtered ultrafiltration return sludge to the denitrification reactor.

[0033] Such as figure 1 As shown, the denitrification reactor includes a denitrification rea...

Abstract

The invention discloses denitrification equipment and method for landfill leachate. The denitrification equipment for the landfill leachate comprises a denitrification reactor, a nitration reactor and an external ultrafiltration device, the denitrification reactor comprises a denitrification reactor body, a water distribution device, a filler layer and a hydraulic stirring device; the nitration reactor comprises a nitration reactor body, an aerator and a fan, and the nitration reactor body is communicated with the denitrification reactor body; the aerator is arranged on the inner side of the nitration reactor body, and the fan is connected with the aerator; and the external ultrafiltration device is communicated with the nitrification reactor body, and the external ultrafiltration device is communicated with the water inlet pipe of the ultrafiltration return sludge. According to the denitrification equipment and method for the landfill leachate, the denitrification effect is good, the application range is wide, and the treatment cost, operation energy consumption and agent consumption of the landfill leachate are reduced.

Description

technical field [0001] The invention relates to the technical field of organic wastewater treatment, and more specifically, to a denitrification device and method for landfill leachate. Background technique [0002] With the increasingly stringent sewage discharge standards, the total nitrogen removal capacity of biochemical treatment technology is particularly important for the discharge of landfill leachate. With the gradual advancement of the marketization of the waste treatment industry, the competition in the industry has intensified significantly. Landfill leachate is a secondary pollutant, and its treatment costs account for a relatively high proportion of the entire waste treatment. How to reduce the cost of garbage disposal is not only related to government financial expenditure, but also related to the market competitiveness of various related enterprises. [0003] At present, most of the biochemical treatment of landfill leachate in the industry uses nitrifying b...
