Description
Technical field
The present invention relates to environmental technology fields, and in particular to a kind of repair materials for organic material contaminated soil and repairs
Compound method.
Background technique
With being constantly progressive for China's development, the pollution situation of soil environment is further serious.The harm of soil pollution
It is numerous, cultivated land resource originally in short supply can be made deficienter, while bringing adverse effect to agricultural development；Pollution in soil
Object can migrate or be detained in the soil, to the environment of surrounding cause long lasting for influence；Soil pollution can be to economic construction
It makes a very bad impression, it is serious to hinder economic sustainable development；Soil pollution greatly threatens the body and health of the mankind, together
When also have complicated reciprocal effect with other pollutions.
For the peculiar smell and volatile contaminant generated during contaminated soil remediation, domestic general technology is to build to face
When peculiar smell warehousing storage or soil is covered using inflating green and steel construction greenhouse etc., above-mentioned construction, which exists, to be made
The disadvantages of tail gas needs processing that high price is expensive, can not move, collect easily causes secondary pollution.At home and abroad start to seek at present
Inhibit the evaporation of inflammable toxic chemical with foam.
Scott Metcalfe (Pollution Engineering, 2005 (2): 12-15) has reported 3 kinds and has inhibited gas processed
The method of factory's contaminated site peculiar smell and VOCs pollutant: interim storage is collected, film covering and aqueous foam cover.Aqueous bubble
Foam covering method have easy to use, long action time, effect is good, economy is high, does not delay construction speed, without secondary dirt
The advantages that dye.Its method is that aqueous foam is sprayed to Zhi Qi factory Polluted area, can effectively inhibit stench in 13-14 hours
And the release of VOCs pollutant.
Patent US7659316 (B2) (2007) is related to a kind of foam compositions, is suitable for the covering such as refuse landfill,
Forest fire protection, the fields such as escaping gas emission control.Foam by protein hydrolysate, ferrous sulfate, cationic modified starch and its
He is at being grouped as.Patent is related to influence of the different foam formula to foaming fluid viscosity, concrete application case, effect for foam
Fruit and evaluation method do not refer to.
A kind of method that patent CN201310431852.1 (2014) has invented foam pollution administration soil, foam component
Are as follows: protein hydrolysate, cationic modified starch GPC X201, FeSO4, hexylene glycol, chloro- 2 benzyl of 4- pour phenol, sodium lignin sulfonate,
Polysaccharide xanthan gum, polyacrylamide and water.Its administering method is foam coverage after foaming in contaminated soil surface layer, is utilized
Pollutant in the adsorption ability and the absorption of sterilization composition and resolution soil of foam, by 20 more than hour, will steep
Foam is sprayed after foam cleaning again, circulation is until soil is up to standard.The method only relates to foam and makees to the reparation degradation of contaminated soil
With, and do not refer to foam to the block function of peculiar smell stench.
Li Jianhuas etc. (fire prevention and product information, 2000,8:24-26) have rated fire foam to inflammable or have
Venom body lets out the effect that covering is implemented on beach, as a result, it has been found that MJPZ is best to the coverage effect of n-hexane, effective cover time can
Up to 120min.But it is fluorine-containing in MJPZ, secondary pollution may be caused to environment.
Mulligan C.N. (Engineering Geology, 2003,11:269-279) etc. has studied through surface-active
Repairing effect of the modified foam of agent to pentachlorophenol (PCP) contaminated soil.Its method is injected foam as leacheate
Into contaminated soil, as a result, it has been found that in the 1% removable soil of triton x-100 85% PCP is added in the foam.It is added to
The foam leacheate specific surface activating agent leacheate of surfactant can more effectively remove the PCP pollutant in soil.This research
Involved in foam injection into contaminated soil and by the method for pollutant elution removal, with this patent refer to by foam coverage
On contaminated site surface, thus the method for inhibiting and eliminating place peculiar smell and VOCs pollutant, the two application principle not phase
Together.
A kind of method that patent CN103230916A (2013) has invented foam inhibition dust, method is that foam is molten
Liquid is added in the water tank of dustproof spray nozzle, sprays to form mist through atomizer, forms a large amount of atomization bubbles through multiple nozzles
The foam area of coverage is adsorbed on the fugitive dust overwhelming majority in atomized foam overlay area on foam, and settles with water mist to reach
Ideal anti-dust effect.Foam main component is nonionic surfactant, anionic surfactant, hygroscopic inorganic salts
Flocculating agent, assistant for emulsifying agent.This patent only relates to application of the foam in terms of inhibiting dust, be not directed to foam inhibit peculiar smell and
The application of volatile contaminant.
