Spend field of waste water treatment.
Background technology
In recent years, the annual generation in city is with 8%~10% speed sharp increase.Traditional house refuse
There are mainly two types of processing approach, garbage loading embeading or power generation by waste combustion.Heap ferment before garbage loading embeading or burning can all generate a large amount of rubbish
Rubbish Leachate site.Due to house refuse complicated components, moisture content fluctuation is larger, while the environmental condition (heap during rubbish heap ferment
Ferment temperature, heap ferment time, air humidity, precipitation.Regional condition etc.) there is uncertainty, therefore garbage incinerating power plant oozes drip
Liquid complicated components, organic pollutant category is more, and variation range is big, in addition rainfall, rubbish pit temperature, time of stacking garbage etc.
Factor also influences the ingredient of percolate, therefore there are the complexity of short-term fluctuation and change in long term for percolate COD concentration.It is overall
For, garbage leachate has the characteristics that high chemical oxygen demand (COD), high ammonia nitrogen, high salinity, unbalanced nutrition, belongs to difficulty
Manage high-concentration waste water.
Currently, the treatment process of garbage leachate generally uses " pretreatment+anaerobic digestion+Aerobic Process for Treatment+advanced treating "
Equal Physiochemical and biochemicals group technology.Although these group technologies achieve good treatment effect, there are still some to need
