The invention discloses a treatment method for garbage leachate. The treatment method comprises the following steps: putting the garbage leachate into a microbiological treatment system; completely degrading the garbage leachate through electro-microorganisms and generating electric energy; carrying out centrifuging and extraction filtration on output water of an anode chamber of the microbiological treatment system and removing large-particle substances and taking supernatant; enabling a raw material solution to enter a positive penetration device; adjusting flows of the raw material solution and a drawing solution to keep the flows consistent; enabling the raw material solution and the drawing solution to enter from the lower part of the positive penetration device by adopting a crossed flow manner and return from the upper part of the positive penetration device; and calculating changes of mass in the drawing solution. The invention provides a process for treating the garbage leachate through combination of a microbiological fuel cell and a positive permeable membrane; output water of the microbiological fuel cell is used as positive penetration input water; and an active layer of the positive permeable membrane is arranged toward one end of the raw material solution and the content of organic matters and ammonia nitrogen is effectively reduced; and meanwhile, dirt removal and electric energy generation are realized.
Description
technical field [0001] The invention relates to a treatment method for landfill leachate, which belongs to the technical field of environmental engineering wastewater treatment. Background technique [0002] The landfill leachate contains a large amount of organic matter and ammonia nitrogen, the water quality changes greatly, and the composition is quite complex. It has the characteristics of high COD and ammonia nitrogen content, and the imbalance of microbial nutrient elements. Microbial fuel cell (MFC) technology, which uses the metabolism of microorganisms to convert chemical energy into electrical energy, is a new type of sustainable energy technology with high energy conversion rate and low environmental pollution. Microbial fuel cell (MFC) is used in landfill leachate, which can not only purify and generate electricity, but the high content of COD and ammonia nitrogen in the leachate can make MFC have higher conductivity and lower internal resistance. However, a s...
