Description
Technical field
The present invention relates to penetrating fluid processing technology field, in particular to a kind of garbage loading embeading permeates liquid processing method.
Background technique
As China city numbers increase and population increases, municipal refuse is also with sharp increase.According to statistics, annual life
It produces rubbish and has reached 1.5 hundred million tons, it is average to be increased with the speed in 9%/year, wherein untreated rubbish is 7,000,000,000 tons existing, account for
The 8.3% of China soil sum.It is expected that in following 20 years, the discharge amount of solid waste by occupy 85% land, the whole nation
All there is serious refuse pollution in most area.The processing of domestic waste should follow minimizing, recycling, harmless
The principle of change mainly has landfill, compost at present and burns three kinds of processing methods.
Landfill method refers to using natural feature or manual construction, forms certain space, and rubbish filling, compacting, covering are reached
To the purpose of storage.With investing, small, operating cost is low, operation equipment is simple, can handle multiple types for garbage loading embeading processing
Rubbish the features such as.But rubbish, which encounters rainwater weather when landfill, can generate penetrating fluid, penetrating fluid is easy contaminated soil
And the polluted source after earth's surface inflow underground water, therefore the processing of penetrating fluid is the important means of rubbish security landfill.
The processing method multiplicity of landfill leachate, effect are irregular;But in actual application, a certain kind side is only leaned on
Method is difficult to reach processing requirement to handle, it is necessary to using the combination of a variety of methods.The landfill leachate treatment in China at present
Mostly use based on biological method, the group technology supplemented by physical chemistry method, it is excessively high but there are still costs, handle it is unstable, and
The problems such as pollutant removal is not comprehensive enough.

The export of UASB reactor head, mud granule slide the Sludge Bed for being settled down to reactor bottom automatically, and penetrating fluid is reacted from UASB
Device outflow;
The secondary Anaerobic Treatment of S4, penetrating fluid: being passed through anaerobic baffled reactor (ABR) for the penetrating fluid of step S3, leads to
It crosses baffle plate and realizes that the effect of similar two-phase separation separates penetrating fluid and sludge, infiltration is flowed out from ABR reactor;
The Air Exposure of S5, penetrating fluid: the penetrating fluid of step S4 is passed through in batch-type interval activated sludge tank (SBR) and is led to
It crosses and realizes that microorganism degrades to the organic pollutant inside penetrating fluid, precipitates organic sludge, upper layer by intermittent aerating mode
Penetrating fluid flowed out from the pond SBR;
S6, infiltration liquid disinfectant: the penetrating fluid of step S5 is passed through in sterilization pool and reaches by disinfection and meets discharge standard
Liquid discharge;
S7, Treatment of Sludge: the sludge of step S3, S4 and S5 are sent into concentration basin and pass through free settling, flocculating setting, region
Sedimentation, Compression Settlement process slough partial moisture.
Preferably, for Ca0, the penetrating fluid pH value after adjusting is the alkaline conditioner that the conditioning tank of the step S1 uses
10-12。
Preferably, the grizzly bar gap of the fine fack of the step S1 is 16-25mm.
