Embodiment Construction
[0026] Such as figure 1 As shown, an ion exchange column reactor 7 for treating landfill leachate has a cylindrical shell, the top of the shell is provided with a water outlet 1 and a gas vent 2, and the bottom of the shell is provided with a waste water inlet 6, regeneration liquid The water inlet 5 and the waste liquid vent 9, the inside of the reactor are divided into four layers with three porous baffles 3 of plastic steel material, and the intermittent agitator 4 of tetrafluoroethylene material is arranged between the adjacent two porous baffles. NanoChem molecular sieves are filled between the three porous baffles 3 in the exchange column reactor 7 . The aperture diameter of the pores on the porous baffle 3 is 1.5mm, which is smaller than the particle diameter (3mm) of the NanoChem molecular sieve.
[0027] Such as figure 2 As shown, the device for treating landfill leachate using the above-mentioned ion exchange column reactor includes an ion exchange column reactor ...

Abstract
The invention discloses an ion exchange column reaction equipment for treating waste percolate, which comprises a shell, wherein the lower end of the shell is provided with a waste water inlet, a recycling liquid inlet and a waste liquid draining opening; the upper end of the shell is provided with a water outlet and a gas exhaust opening; a batch agitator and a porous baffle plate are arranged in the ion exchange column reaction equipment; and an ion exchanger is filled into the ion exchange column reaction equipment. The reaction equipment of the invention uses a NanoChem molecular sieve which has high stability and can be recycled as an ion exchange medium; and by mounting the porous baffle plate and the batch agitator in the reaction equipment, the invention solves the problem of stage blockage of the molecular sieve, improves the treatment efficiency of the waste percolate and the recycling effect of the ion exchanger, reduces the energy consumption of the reaction equipment and has certain social and economic benefits.
Description
technical field [0001] The invention relates to an ion exchange reactor, in particular to an ion exchange reactor for treating landfill leachate. Background technique [0002] At present, my country's garbage disposal mainly adopts the method of sanitary landfill. During the landfilling and stacking process of garbage, due to compaction, rainfall, microbial decomposition of organic matter and free water in garbage, a certain amount of high-concentration organic wastewater is formed through leaching and infiltration, that is, landfill leachate. The landfill leachate contains a large amount of organic matter, high concentration of ammonia nitrogen and heavy metal ions and other pollutants, and the COD and BOD values are very high. Among them, acidic fermentation stage: COD mass concentration can reach 45000mg L -1 Closure stage: the mass concentration of ammonia nitrogen is as high as 1000mg·L -1 above. The leachate also contains a considerable amount of high-concentrati...
