Abstract: Provided is a dynamic two-way guide and drainage control method for leachate and landfill gas. The dynamic two-way guide and drainage control method is used in a waste landfill. By implementing the present invention, the water-guiding permeability inside the waste body is improved, and the problems that the water level of the leachate is raised, the landfill gas is escaped, the collection efficiency is extremely low and the like during a waste landfilling process at present are solved.

Abstract: Provided is a method for performing anaerobic digestion by utilizing a heavy metal ion enriched biomass waste material, comprising: putting a biochar made from the raw materials such as garden rubbish and agricultural and forestry waste, or a plant for adsorbing heavy metal ions in waste water containing heavy metal ions, and obtaining a heavy metal saturated biochar or a heavy metal super-enriched plant; and then adding in a kitchen waste anaerobic digestion methane generation system at a certain ratio. The heavy metal ions adsorbed in the plant or the biochar are utilized as a basic component of an anaerobic reaction enzyme to promote the growth of methane bacteria, activate the activity of the enzyme, shorten the time of a hydrolysis acidification stage, reduce VFA accumulation, and accelerate the generation of energy products such as methane and the like.
