Problems solved by technology

[0006] There are also studies that show that the leachate is treated with mineralized waste, and the removal rates of COD and ammoniacal nitrogen in the leachate show periodic fluctuations; and because Mineralized waste particles are too fine (d≤6mm), and the reaction bed is prone to clogging after a period of operation, resulting in a decrease in the permeability of the bed and deterioration of the effluent quality

Abstract

The invention discloses a method for processing rubbish filtration and the special apparatus. The method for processing rubbish filtration has the advantages that (1) resolving the problem of blocking of the waste reactor, (2) accelerating stabilization of the rubbish for detecting and shortening the landfill waste cycle and filtration processing cycle, (3) achieving zero discharge of the filtration, (4) realizing the sustainable development of the landfill waste site, (5) can flexibly control the recharge rage.

Description

technical field [0001] The invention relates to a method and a special device for treating landfill leachate. Background technique [0002] A large number of laboratory and field experiments abroad have shown that leachate recharge has the advantages of accelerating landfill stabilization, improving leachate water quality, increasing the gas production rate of waste, accelerating settlement, and reducing landfill operating costs. However, in the practice of using fresh landfill layer for leachate recharge treatment, some problems have appeared, mainly as follows: the leachate water quality maintains acidification for a long time during the recharge process, the concentration of organic matter is difficult to decrease, and the concentration of ammonia nitrogen is high. . On the basis of deepening the understanding of these problems, researchers have done a lot of work. While recharging leachate abroad, they have taken measures such as adjusting the pH value of the leachate, ...
