Description
Technical Field
The invention belongs to the technical field of environmental protection and new energy, and particularly relates to a device for accelerating methanation of landfill garbage.
Background
The sanitary landfill is one of the main methods for treating domestic garbage in China. However, the traditional sanitary landfill technology has the problems of long time for stabilizing the garbage, complex and difficult treatment of percolate components, low landfill gas yield, difficult recycling and the like. Aiming at the problems of the traditional sanitary landfill, in the 20 th century and 70 th century, a bioreactor landfill technology taking percolate recharging as a main control measure is produced. The bioreactor landfill mainly comprises several types, such as a recharge type, a two-phase type, a denitrification type and the like. Wherein the denitrification bioreactor landfill technology is concerned in the fields of domestic garbage landfill and leachate treatment because the problem of overhigh ammonia nitrogen concentration of leachate can be solved from the source.
Compared with the prior art, the heterotopic nitrification and in-situ denitrification type bioreactor landfill technology firstly treats the percolate, converts ammonia nitrogen in the percolate into nitrate nitrogen, and then converts the nitrate nitrogen into gaseous nitrogen by utilizing the anaerobic environment and microorganisms of a landfill. However, researchers have also found that recharging the nitrified leachate to a fresh landfill produces better denitrification, but at the same time the nitrate inhibits methane production.
The main reason for the inhibition of the methanation process is that nitrate has an effect on the activity of the methanogenic microorganisms. During the denitrification process, due to the competition of nitrate for molecular hydrogen, the over-high nitrate concentration can inhibit the methane production process from going smoothly.
Therefore, for the ex-situ nitrification and in-situ denitrification type bioreactor landfill technology, the concentration of nitrogen in the recharge nitrate must be reduced to promote the waste methanation in the in-situ denitrification stage and accelerate the waste stabilization. According to the classical biological denitrification theory, in the nitrification stage of converting ammonia nitrogen into nitrate, the reduction of the nitrate is bound to reduce the ammonia nitrogen removal rate, thereby leading to the reduction of the total nitrogen removal rate of the system. Therefore, the key problems to be solved are to ensure the ammonia nitrogen removal rate in the ectopic nitrification stage and to reduce the nitrate concentration of the leachate which is fed back to the in-situ denitrification stage.
