Description
Technical field
The invention belongs to field of sewage treatment, and in particular to a kind of rural garbage is percolated liquid tower processing unit.
Background technology
Rural garbage percolate refers to moisture, the rain into landfill that rubbish contains in itself in the landfill of rural garbage
Snow-broth and other moisture, rubbish, the saturation moisture capacity of overburden layer, and a kind of high concentration for undergoing waste layer and overburden layer and being formed
Organic wastewater.
In view of the characteristics of residents in rural community pollution is wide, relatively scattered, in recent years, numerous scholars are administering life in the countryside rubbish
Beneficial exploration has been carried out in terms of rubbish methods and techniques means：
Due to the anisotropism and variability of economic level and humanistic environment difference, and rural area landfill waste, both at home and abroad
Scholar is analyzed heavy metal source in the landfill waste of rural area.Ren Fumin etc. is to Beijing Suburb landfill waste sampling analysis knot
Fruit shows that the content of Cu, Zn, Pb content is beyond the index of national regulation in landfill waste.Austria etc. has investigated Three Gorges in king
The content of beary metal of reservoir area small towns landfill waste, wherein As, Hg, Pb, Cd content equally exceed standard.Fryhammar etc. is ground
Study carefully the heavy metal concentration highest found in the landfill waste of rural area, Zn and Cu contents are respectively up to 267.7mg/kg and 139mg/kg.
It is different from the sorting of city landfill waste, differentiated control so that existing rural area fills rubbish because landfill waste generating source is sufficiently complex
In the report that heavy metal source is studied in rubbish there is many differences in data.
Developed area township industry flourishes, and its refuse landfill contains a large amount of trade wastes so that a huge sum of money
Category is resided in the refuse landfill of small towns, and it remains the sustainable release hundreds of of heavy metal even more than one thousand years.Therefore, small towns need to be filled out
The environmental behaviour for burying heavy metals in garbage carries out Continuous Observation, meanwhile, the environmental behaviour of heavy metal in landfill waste should be carried out
Effective environmental impact assessment.Deng Huan is extensively waited using potential ecological risk assessment to Shanghai City Lao Gangzhen refuse landfill tidal flats
The content of rubbish heavy metal is evaluated, and it is Zn to show Lao Gang towns tidal flat Heavy Metal Pollution>Cu>Pb>Cr, this 4 kinds of members
Potential ecological hazard caused by element is medium that wherein Cu and Pb toxicity contribution are larger.
Heavy metal migration, conversion and bio-toxicity in the environment and its chemical form are closely related, meanwhile, heavy metal
Environmental behaviour be also to be determined by its form.However, the research on Speciation Analysis of Heavy Metals in landfill waste is seldom,
Flyhanunar etc. have studied the release row of heavy metal in fine grained rubbish under the conditions of garbage aerobic fills using continuous extraction

Existing COD detection methods
COD (Chemical Oxygen Demand, abbreviation COD) refers under strong acid and heated reflux condition, uses
Strong oxidizer (such as potassium bichromate, potassium permanganate or Potassiumiodate) aoxidizes to organic matter in water body, and adds Ag+As urging
Agent, the amount for reacting consumed oxidant is converted into the amount of oxygen, its unit is mg/L.Due to organism kinds in waste water
A lot of, composition is complicated, it is difficult to which qualitative and quantitative, so the overall target polluted by the use of COD as water body organism, oneself turns into water for it
One of important parameter that quality supervision is surveyed, it is significant to grasping degree of water pollution in time.Existing COD detection technique
It is as follows.
1. National Standard Method (titration)
At present, the standard method of China COD measure mainly has two kinds of potassium dichromate method and permanganimetric method.Potassium dichromate method
The general principle of (GB 11914-89) is as follows:In strongly acidic solution, catalyst Ag2S04In the presence of, with strong oxidizer K2Cr2O7
The organic matter in water is aoxidized, uses (NH after condensing reflux 2h at a certain temperature4)2Fe(SO4）2Titration, according to the K of consumption2Cr2O7
Chemical oxygen consumption (COC) is calculated in amount, and is represented with the concentration (mg/L) of oxygen.This standard method is applied to sanitary sewage and Industry Waste
The monitoring of water, its advantage are degree of accuracy height, favorable reproducibility；But analytical cycle is grown, high energy consumption, it is difficult to carry out batch quantity analysis;And
Mercury salt, chromic salts are needed to use, secondary pollution can be caused.Although current many researchers are improved around digestion procedure, such as
Using airtight digestion method, open pipe heating resolution method, Microwave Digestion and Sonic chemical digestion method etc., but fail to be inherently eliminated
The problem of secondary pollutions such as chromic salts.
Permanganimetric method is divided into acidic potassium permanganate method and basic potassium permanganate method again.Acidic potassium permanganate method is in water sample
It is middle to add sulfuric acid and the potassium permanganate of excess carrys out oxidation of organic compounds, the oxalic acid sodium reduction of superfluous potassium permanganate excess, finally
With the superfluous sodium oxalate of standardized potassium permanganate solution titration, according to the consumption of liquor potassic permanganate, the COD of water sample is calculated
Value.Alkali formula potassium permanganate rule is that aqueous slkali and excessive potassium permanganate are added in water sample, after heating, adds excessive oxalic acid
Sodium and sulfuric acid solution, superfluous sodium oxalate uses liquor potassic permanganate residual titration again, so as to try to achieve the COD of water sample.Both approaches are all
Suitable for not contaminated or light contamination water sample, difference is that acidic potassium permanganate method can only analyze chlorion and be less than
300 mg/L water sample, basic potassium permanganate method can then analyze the water sample that chlorion is more than 300 mg/L.Although this method pollutes
It is relatively low, but the shortcomings of time-consuming, oxidability is poor, accuracy of measurement is low, the scope of application is narrower be present.
2. spectroscopic methodology
The most frequently used COD spectrometries are a ultraviolet visible spectrophotometries, can be divided into again direct measuring method and indirectly
The class of determination method two.The former is to directly obtain COD value by measuring the ultra-violet absorption spectrum of organic matter in water sample.Such as Zhang Guofeng
Deng there is the principle that absorbs by force in ultraviolet spectrum area according to organic matter, it is determined that between the COD and absorbance of experimental branch line waste water
Dependency relation, and establish equation of linear regression.Indirect detection rule is to add the weight of excess under basic or acidic conditions
Potassium chromate or other oxidants, oxygen is detected by spectrophotometer after the reducing substances under certain condition in complete oxidation water
The absorbance of agent realizes the measure of COD value.Such as Jiang etc. passes through the suction of water sample under 440 nm of measure and 560 nm wavelength
Luminosity, the concentration difference of dichromate ion before and after resolution is tried to achieve, dichromate ion is dense before and after being reacted based on COD with resolution
Degree difference is proportional, and then tries to achieve the linear relationship of water sample COD value and absorbance under dual wavelength.The method has deducted suspended particulate or instrument
The influence of spectrum baseline drift caused by device stability, improves the reliability of COD measure, easy to operate, and the method is adapted to
Determine COD<100mg/L water samples, detection are limited to 8.6 mg/ L.
In addition, determination by way of chemiluminescence analysis COD value also has been reported that.Its principle is to utilize oxidant (such as potassium bichromate)
Aoxidize water body in reducing substances, while produce material can be with cataluminescence system (such as Luminol-H2O systems) production
Raw strong chemiluminescence, and caused chemiluminescence intensity has certain linear relationship with water sample COD.Such as Liu passes through measure
Caused Cr after bichromate oxidation water sample3+With Luminol-H2The chemiluminescence intensity of O systems realizes COD detection, its
The range of linearity is 0.27-l0g/L, and detection is limited to 100 mg/L.And for example Silvestre etc. utilizes CdTe quantum in ultraviolet lighting
Penetrate the light base free radical of lower generation and oxygen radical produces chemiluminescence to aoxidize luminol, if organic matter in water sample be present, have
Machine thing can consume part free radical, and the free radical for aoxidizing luminol is reduced, then corresponding chemiluminescence intensity weakens, and is based on
This principle establishes the linear relationship between the decrease of luminol chemiluminescence intensity and water sample COD.This method range of linearity is 1-
35 mg/L, and quantum dot is used for COD measure first, make COD measure sensitiveer, accurate, quick, this method is every
Hour can determine 33 water samples.
(1) potentiometry
Potentiometry is that the change of solution potential before and after being cleared up based on measure carries out COD detection.Dugin etc. is with Ce
(S04) 2For oxidant, potential is directly determined using pH electrodes and oxidation-reduction electrode, is successfully realized the measure of COD value.Zhu
Person of outstanding talent etc. uses oscillographic potentiometric titration, and sample is handled using technique of backflow, and excessive potassium bichromate is titrated with standard liquid, with
Phosphor dot sports terminal so as to realize the measure to water sample COD on oscillographic potentiometric titration instrument.Beliustiu etc. with two kinds not
Same glass electrode composition battery, directly determines potential to determine the COD value of water sample.
3. coulometric titration
Coulometric titration is in acid medium, uses K2Cr2O7Oxidizer treatment water sample, Fe caused by excessive solution2+As
Titrant is titrated, and Fe is produced according to electrolysis2+The electricity consumed, law are calculated.Such as Zhu Shoufa coulometric titrations
Method successfully determines the K of waste-water from coal mine2Cr2O7Electricity consumption and according to faraday's COD value.This process simplify demarcation volumetric soiutions
Step, return time is shortened, operation is easier, and faster, precision is higher for analyze speed.In addition, what German, Chen Zhijun etc. is also
For Railway Project present in coulometric titration, such as reappearance, stability are poor, terminal is difficult to judge, are studied and changed
Enter, further increase the degree of accuracy of measure.Above-mentioned potentiometry and coulometry method still have analysis time is long, operation compared with
It is cumbersome, secondary pollution problems can be produced.
4. coulometry
Coulometry refers to apply certain voltage on the working electrode (s, the organic matter in water sample is electrolysed completely, according to disappearing
The electricity of consumption calculates COD value, and the key of this technology is with the organic matter in 100% efficiency all oxidation water body.Such as Lee
Etc. prepare a kind of Cu electrodes be working electrode micro electrolytic cell, waste water water sample is determined by Depletion electrolyzing organic
COD value, its range of linearity are 1-10 mg/L, and electrolysis completely only needs 30 min.This method is compared with potassium dichromate method, analysis efficiency
Greatly improve.Lee etc. improves the structure of this thin-Layer Electrolytic Cell afterwards, minute is foreshortened to 3-10 min, and successfully use
It is consistent with potassium dichromate method in the measure of actual lake water water sample, measurement result.
5. current method
Current method measure COD is to apply certain voltage to working electrode, is aoxidized by detecting organic matter in electrode surface
Caused electric current is realized.This method not oxidant applying, does not heat resolution water sample yet, thoroughly avoids the secondary of chromic salts
Pollution.Such as Ai prepares a nanometer PbO with cyclic voltammetry in Pt electrode surfaces original position2, and using the success of ampere detection technique
Measure for the different COD in water body such as wastewater from chemical industry, pharmacy waste water, municipal sewage, food wastewater and hospital wastewater.It is prepared
PbO2Particle diameter is about 50-70nm, and this considerably increases the adsorption site of electrode surface, accelerates oxidation operation degradation reaction
Speed, so as to improve measure sensitivity.Li etc. utilizes F doping PbO2Electrode is simultaneously successfully realized with reference to Flow Injection Analysis
COD detection.F doping adds the quantity for the surface site not being occupied, thus significantly improves the electro-catalysis energy of electrode
Power.Ma etc. prepares Sb-SnO using galvanostatic deposition and pyrolytic technique on Ti surfaces2Coating, it is then redeposited to go up PbO2Sensitive layer,
In order to compare, also F- PbO are prepared on Ti surfaces2Coating.Research finds, Ti/Sb-Sn02/ PbO2Electrode can be thorough by organic matter
Bottom is degraded into CO2And H20, the degraded to phenols is compared with Ti/Sb-Sn02/ PbO2Electrode is more effective, and background current is smaller, therefore,
Ti/Sb-Sn02/ PbO2Electrode is more suitable for COD measure.The range of linearity of the electrode is 0.5-200 mg/L, and detection is limited to 0.3
Mg/L, and it is used successfully to the COD analyses of synthesized slit and actual water sample.
Although PbO2Electrode achieves good effect in terms of COD is determined, but also has its defect, is mainly manifested in electrode
Prepare cumbersome, use range is limited, electrode repairs hardly possible and service life is short etc..Therefore, other new COD sensitive electrodes also phase
After report.Such as Yu etc. prepares boron-doped diamond (BDD) on T1 surfaces with microwave plasma CVD technology
Film, COD sensitive, quick measure is realized using ampere detection technique, the range of linearity is 20-9000 mg/L, and detection is limited to
7.5 mg/L.The electrode possesses that electrochemical window is wide, background current is small, service life is long, is easy to from purifying activator, recyclable makes
With many good characteristics such as, stability and reappearance are high, environment compatibility is good.Hereafter, Yu etc. again by Flow Injection Technique with
BDD electrodes are combined, and further increase COD measure sensitivity, range of linearity 2-75 mg/L, and detection limit reaches 1 mg/L.The method
In situ, on-line monitoring is realized, analysis time is not only substantially reduced, improves reappearance, and significantly reduces reagent use
Amount, it is more environmentally friendly.
In addition, Si1va etc. is prepared for Cu/CuO electrodes, and has developed a kind of measure COD electrochemical method, with linearly sweeping
The range of linearity for retouching method measure COD is 53-2801.4 mg/L, the mg/L of detection limit 20.3, and is used successfully to actual waste water
Measure.In alkaline medium, Cu/CuO electrode surfaces can produce substantial amounts of Cu/CuO, and then by organic matter Quick Oxidation, so that
Realize COD quick, Sensitive Detection.
