Problems solved by technology
[0004] Due to the high pollution of landfill leachate, the methods currently used are mainly double-membrane method or biochemical treatment + membrane treatment. Its main feature is that concentrated water with extremely high salt concentration will be produced during the membrane concentration process. It is recharged to the landfill, so that the salt concentration in the landfill leachate is getting higher and higher, and the treatment becomes more and more difficult
However, the cost of treating the concentrated liquid by evaporation is too high, and it can only be promoted in economically developed areas.

Abstract
The invention discloses a landfill leachate wastewater treatment system and a treatment method. The landfill leachate wastewater treatment system comprises a coagulation floatation tank, a primary anaerobic tank, a primary aerobic tank, a facultative reaction tank, an inorganic membrane MBR tank, a micro-nano catalytic ozonation tank, a biological aerated filter and a disinfection tank which are connected in sequence. The landfill leachate treatment method comprises the landfill leachate wastewater treatment system. According to the scheme, the landfill leachate is effectively treated, the wastewater is completely discharged after being treated, no concentrated solution is generated, and adverse effects on landfill and subsequent landfill leachate treatment are avoided.
Description
technical field [0001] The invention relates to the technical field of water treatment technology, in particular to a landfill leachate wastewater treatment system and a treatment method. Background technique [0002] With the rapid growth of urban scale and population, the total amount of municipal solid waste continues to increase, and the amount of leachate generated during the sanitary landfill process is also increasing rapidly. Some soluble substances produced after a series of fermentations of garbage. [0003] The water quality of landfill leachate is quite complex, with high COD concentration but poor biochemical properties, high ammonia nitrogen concentration, high salt content, a certain amount of heavy metals, and an imbalanced ratio of carbon, nitrogen and phosphorus. Landfill leachate not only pollutes soil and surface water sources, but also pollutes groundwater. [0004] Due to the high pollution of landfill leachate, the methods currently used are mainly d...
