Description

A kind of garbage loading embeading infiltration liquid processing method
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.
Summary of the invention
The object of the invention is that handling incomplete problem to solve the processing cost of above-mentioned landfill leachate height And a kind of garbage loading embeading infiltration liquid processing method is provided, secondary Anaerobic Treatment and Aerobic Process for Treatment with microorganism combine, and locate The advantages of reason better effect, Anaerobic Treatment reduces cost using UASB reactor and ABR reactor.
The present invention is achieved through the following technical solutions above-mentioned purpose, and a kind of garbage loading embeading permeates liquid processing method, including Following steps:

An Anaerobic Treatment of S3, penetrating fluid: the penetrating fluid after step S2 ammonia nitrogen removal is passed through up-flow anaerobic sludge blanket Reactor (UASB), UASB reactor bottom have a Sludge Bed, and the majority of organic pollutants in penetrating fluid is passed through here Anaerobic fermentation is degraded to methane and carbon dioxide, because of the agitation of water flow and bubble, forms a sludge suspension layer above Sludge Bed, UASB reactor head has equipped with three phase separator, and to gas, penetrating fluid and the mud granule after separation and fermentation, gas is certainly 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.
Preferably, the carrier gas in the step S2 is air or water vapour.
Preferably, in the step S6 sterilization pool sterilization method be liquid chlorine disinfection, chlorine tablets disinfection, disinfection by chlorine dioxide, Bleaching powder disinfection, hypochlorite disinfectant and ozonization one of which.
Compared with prior art, the beneficial effects of the present invention are: will detest inside penetrating fluid by using secondary Anaerobic Treatment Oxygen organic is degraded, and secondary Anaerobic Treatment uses UASB reactor and ABR reactor respectively, and pole is suitable for handling highly concentrated Waste water is spent, and sludge loss loss is smaller, is not required to set mixed stirring device, and sludge blockage problem is not present, and reduces maintenance cost, More economically, the aerobic organic matter in penetrating fluid inside is handled by using SBR Air Exposure mode, is detested twice to realize Oxygen processing is combined with an Aerobic Process for Treatment, and organic matter is more complete inside processing penetrating fluid;This method is also by penetrating fluid Internal ammonia nitrogen is handled, and eutrophication situation is avoided to occur, and the penetrating fluid rear sludge generated processed passes through freedom Sedimentation, flocculating setting, regional subsidence, Compression Settlement process come slough partial moisture can be convenient collection be used to secondary use.
