The waste water generated of standing mainly has sanitary wastewater, flushing waste water, landfill leachate.Wherein sanitary wastewater is that transfer station staff exists
The waste water generated in daily life, work；Flushing waste water mainly includes that ground, vehicle and equipment rinse the waste water generated；Rubbish
Percolate is rubbish through generating in compression process, its main feature is that pollutant concentration is high, change of water quality range is big, simultaneous with strong
Strong stench is in black or taupe.Although rubbish residence time in garbage transfer station is short, percolate quantum of output is smaller, by
In the high pollution of percolate, it is necessary to be dealt with objects as the emphasis of terminal waste water.
Similar with refuse landfill, burning power plant, leachate in garbage transfer station has following characteristics: 1) pollutant composition
Organism kinds are more in complicated and changeable, the big landfill leachate of change of water quality, and organic matter contained therein is mostly humic class high score
Sub- carbohydrate etc. includes the hardly degraded organic substances such as heterocyclic arene, polycyclic aromatic hydrocarbon, phenol, alcohol, amino benzenes compounds, thus its
Water quality be it is considerably complicated, pollutant kind is more, and there are the complexity of short-term fluctuation and change in long term for concentration.2) organic
The pollutant concentrations such as the high terminal percolate organic matter of pollutant (COD), ammonia nitrogen concentration, ammonia nitrogen are higher, and COD concentration exists
10000mg/l or so.Since the residence time is short in terminal for rubbish, pollutant concentration is relatively low, gives up along with having to rinse
The dilution of water, terminal Landfill Leachate Pollutants concentration are lower than the percolate of landfill yard, burning power plant.Terminal diafiltration simultaneously
Liquid good biodegradability.
According to " consumer waste infiltration liquid processing technique specification " (CJJ150-2010) the 4.1.3 articles regulation, landfill leachate
Processing preferably uses combined treatment process, and combined treatment process should be with biological treatment for main body technology.Currently, landfill leachate treatment
