[0004] 2. The concentration of ammonia nitrogen is high, the highest can reach several thousand mg / liter, which seriously inhibits and reduces the activity of microorganisms in the biological treatment process
[0005] Landfill leachate has the characteristics of high concentration of pollutants and relatively small amount of treated water. Traditional submerged MBR (membrane bioreactor), contact oxidation, and conventional A / O (anaerobic anoxic / aerobic) equipment are used for landfill leachate There are many disadvantages in the treatment methods, among which the most important disadvantages are: the use of civil construction pools in the prior art, the limitations of high investment in civil construction and equipment, low integration, complicated operation, and inconvenient maintenance and repair.

The invention provides an AO (anoxic and oxic) integrated reaction apparatus suitable for waste leachate wastewater treatment, comprising: a circular reaction tank; a circular wall integrated inside the circular reaction tank, wherein the circular wall divides the circular reaction tank into a center reaction zone acting as a denitrification function zone and an outer circular reaction zone actingas an aerating denitrification zone, the lower portion of the circular wall is provided with a flow hole whereby the center reaction zone is communicated with the outer circular reaction zone; an inflow component, wherein a water outlet of the inflow component is arranged in the upper portion of the center reaction zone; an aerating diffuser mounted radially along the circular reaction tank in the outer circular reaction zone, wherein the aerating diffuser is connected to an aerator through an aerating pipeline laid along the inner wall of the circular reaction tank in ring form; a first instrument arranged in the center reaction zone and a second instrument arranged in the outer circular reaction zone; an alkaline liquid feeder arranged in the outer circular reaction zone.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an AO integrated reaction device suitable for treatment of landfill leachate wastewater. Background technique [0002] High-concentration leachate, such as landfill leachate, is high-concentration organic wastewater produced by the extrusion of garbage or waste during the stacking process, the decomposition of the garbage itself, and the action of surface water. Landfill leachate has the following characteristics: [0003] 1. The concentration of organic pollutants is high, and the general leachate COD Cr 、BOD 5 It can reach tens of thousands of milligrams per liter, which is close to a hundred times or even more than the concentration of urban domestic sewage pollutants. [0004] 2. The concentration of ammonia nitrogen is high, the highest can reach several thousand mg / liter, which seriously inhibits and reduces the activity of microorganisms in the biological treatm...
