Water quality and quantity is affected by the landfill time limit, and for the landfill leachate of some agings, ammonia-nitrogen content is high, and biodegradability is poor.
As garbage loading embeading year increases, it can be up to 3000mg/L~4000mg/L, the ammonia permeated in filtrate is mostly deposited in the form of ammonia nitrogen
Accounting for about the 70%~80% of TN.With the sternness of environmental protection policy, the drainage requirement of garbage sanitary filling field, garbage transfer station
Reach 2 standard of " household refuse landfill sites contamination control standard " (GB16889-2008) table, COD emission limit 100mg/L；Ammonia nitrogen
Emission limit 25mg/L；Total nitrogen emission limit 40mg/L.
Garbage sanitary filling field, the percolate water yield of garbage transfer station are small, should not carry out large-scale engineering construction.One
As using vehicle-mounted removable two-stage DTRO embrane method equipment handle percolate.DTRO membrane technology is specific to high concentration, high salinity
The characteristics of waste water and researched and developed, to the rejection of COD, ammonia nitrogen in water between 90%-95%.Factory's water quality is filled with certain
" COD:6200mg/L, ammonia nitrogen 2870mg/L ", for, after two-stage DTRO processing, COD:80mg/L in water is produced, ammonia nitrogen:
42mg/L.Production water ammonia nitrogen is exceeded, remaining index is up to standard.
