Description
Technical field
It the utility model is related to wastewater processing technology, more particularly to a kind of depth of percolate evaporation process tail water
Reason system.
Background technology
With the fast development of China's industry, urbanization process is constantly accelerated, and municipal refuse total amount is presented rapid growth and become
Gesture, annual rate of rise are up to 10%.Sanitation Landfill Technology for Refuse is due to the skill such as its technique is simple, cost is low, management is convenient
Art advantage, the at present most commonly used refuse disposal mode of domestic application.Rubbish is during stacking and landfill due to being compacted, fermenting
Deng biochemical degradation, while under the seepage effect of rainwater and underground water, a kind of high concentrated organic wastewater is formd, is claimed
For percolate.Because percolate complicated component, water quality and quantity fluctuation are big, the reasonable disposal of percolate is always
The problem of field of Environment Protection.With《Household refuse landfill sites pollutant catabolic gene standard》(GB16889-2008) promulgation, China pair

Component is frequently changed, and operating cost is very high.In addition, UF membrane can produce substantial amounts of concentrate, concentrate complicated component, if processing
It is improper, it will even more serious pollution is brought to environment.
Pollutant is mainly adsorbed to the surface of solids by absorption method, this method using porous type solid matter, and it is useless to reach removal
The purpose of water pollutant.Conventional adsorbent includes activated carbon, zeolite, flyash, diatomite etc..Although absorption method is in rubbish
Certain effect is obtained in percolate treatment processing, but adsorbent adsorption capacity is limited, and regeneration difficulty is big, and replacement cost is high.In addition,
Enriching pollutants are finally simply transferred on adsorbent by absorption method, its thoroughly degraded removal can not easily be formed into secondary dirt
Dye.
Fenton oxidation method, mainly with ferrous ion (Fe2+) catalyst is used as, utilize Fe2+And H2O2Chain reaction catalysis
Hydroxyl radical free radical of the generation with strong oxidizing property, less toxic or nontoxic small point of small molecule is oxidized to by the organic pollution in waste water
Sub- material.This method is applied widely, oxidability is strong and will not cause secondary pollution.It is real with increasing for its engineer applied
Many problems are exposed in the running of border.1. sludge quantity is big, processing cost is high；②Fe2+And H2O2The difficult control of ratio is added, is gone out
Water easily returns color, remaining H2O2Increase water outlet CODcr；③H2O2It is high to remove complex process, cost；4. treatment effect is unstable.
