LANDFILL LEACHATE WASTEWATER TREATMENT SYSTEM AND PROCESS THEREOF

摘要

This invention relates to a refuse landfill leachate wastewater treatment system comprising a collection well, an adjustment tank, a filter, a comprehensive treatment system having a multi-stage anoxic/aerobic pool and a membrane biological reactor. The process of treatment is: waste water enters a adjustment tank in which water quality and quantity are adjusted; the water subsequently enters a filter, and the water is discharged from the filter and enters a comprehensive treatment system having a multi-stage anoxic/aerobic pool and a membrane biological reactor, wherein waster water is biochemically treated to remove the organic substances, nitrogen and ammonia, and then the wastewater is discharged into a catalyzed oxidation tower; the organic substance in waste water is oxidized on effect of ozone and under the existing catalyst function and then the biochemical capacity thereof is enhanced; and then the catalyzed and oxidized waste water enters carbon filter pool, the remaining contaminated matter can be further removed by degradation of the anoxic oxidation of the biological membrane on the packing material in pool, then the output water meets the requirement of National Standard or other relevant industrial standards.
