Abstract

The invention discloses a method for full-amount treatment of landfill leachate by electro-adsorption molecular distillation in the technical field of wastewater treatment, and the method comprises the following steps: performing full-amount treatment on the landfill leachate by using electro-adsorption molecular distillation reactors, namely a raw water regulating tank, an efficient electro-adsorption reactor and an efficient molecular distillation reactor, so as to realize up-to-standard discharge of the leachate; as shown in Figure 1, the equipment comprises a raw water adjusting tank (1), a high-efficiency electro-adsorption reactor (2) and a high-efficiency molecular distillation reactor (3). According to the process method disclosed by the invention, full-amount treatment of the landfill leachate can be realized, pollutants are not discharged into the environment, the ecological environment is protected, and a key problem is solved for full-amount treatment of the landfill leachate.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a method for the full amount of landfill leachate treatment by using electro-adsorption molecular distillation. Background technique [0002] Landfill leachate is a difficult-to-treat high-concentration organic wastewater, which is characterized by large fluctuations in water quality and quantity, complex components, and high content of toxic and harmful substances. The treatment of landfill leachate has become a major subject of environmental pollution control in my country at present and for a long time in the future (Shen Huan, Jin Qiting, Cui Xiqin, et al. Experimental study on the treatment of urban landfill leachate with an up-flow anaerobic sludge bed [J] ]. Environmental Pollution Control Technology and Equipment, 2004, 5(4): 1-5). Among them, the content of ammonia nitrogen in landfill leachate is high, which is more difficult to deal with. At present, the...
