Description
Technical Field
The utility model belongs to the technical field of sewage treatment, concretely relates to advanced oxidation treatment device of landfill leachate concentrate.
Background
During the stacking and burying process of garbage, due to the biochemical degradation effects of compaction, fermentation and the like, a high-concentration liquid with organic or inorganic components is generated under the seepage action of precipitation and underground water, and the high-concentration liquid is called as garbage leachate, also called as leachate. Factors influencing the generation of percolate are many, and mainly include rainfall condition of a garbage stacking and burying area, the property and the composition of garbage, seepage-proofing treatment condition of a landfill site, hydrogeological conditions of the site and the like.
The chemical oxidation process can effectively eliminate the pollutants without generating chemical sludge in which the pollutants formed in the flocculation precipitation process are concentrated. The process is commonly used for the disinfection treatment of wastewater, but is rarely used for the oxidation of organic matters, mainly due to the economic problem caused by high dosage of the added medicament. For some refractory organic contaminants in leachate, chemical oxidation processes are contemplated. The commonly used chemical oxidants comprise chlorine, calcium hypochlorite, potassium permanganate, ozone and the like, when the ozone is used as the oxidant, the problem of residual sludge is solved, and the acid leachate containing a large amount of organic acid needs higher dosage and longer contact time correspondingly because the organic acid is ozone-resistant.
