Description
Technical field
The present invention relates to the surfactants of soil organic contamination chlorobenzene to enhance the fixed restorative procedure of absorption, belongs to soil
Pollution control field.
Background technique
Organic pollutant is easy to be adsorbed by the solid phase of soil especially soil organism after entering soil, bioavailability
Very low, degradable surfactant can be by between emulsification, desorption and adjusting microbial cell surface, pollutant and surrounding medium
The organic pollutants such as interface interaction bioavailability, to strengthen the biological prosthetic effect of organic polluted soil.Surface
Organic matter can be transferred to I in mobile phase from king's earth solid phase by activating agent, improved the bioavailability of organic matter, made it easier to
It is biodegradable, to achieve the purpose that removal organic polluter I.But some surfactants cannot by complete biodegradable,
A large amount of long-term uses can cause environment potentially to threaten.Therefore, safe and efficient degradable surfactant synergy is selected
Organic pollutant in elution ± earth can in W enhancing king's earth pollutant removal effect, reduce and stop earth ecological risk, ensure and stop earth
Ecological safety.
Tea seed cake is tea seed remaining residue after extracting oil, and the Tea Saponin contained, Tea Saponin is good nonionic table
Face activating agent can be used in the industries such as agricultural protection, medicine, daily use chemicals, construction material and food, as can making full use of to extract
Tea Saponin and reasonable development will generate very big Social benefit and economic benefit.
Summary of the invention
Present invention mainly solves the technical issues of: at present tradition absorption fixation repair chlorobenzene contaminated soil, repair
Low efficiency, required repairing efficiency is long, defect complicated for operation, and the surfactant enhancing for providing soil organic contamination chlorobenzene is inhaled
The restorative procedure of attached fixation.This method by extraction degreasing, methanol extracting, be concentrated and dried and etc. extract and obtain from tea seed cake
The biosurfactant saponin of natural degradable will be added in soil to be processed, watering mixing after itself and zeolite compounding
Standing adsorption solidifies afterwards.Soil remediation method of the invention strengthens boiling using the emulsification of surfactant, desorption
The absorption fixed function of stone, easy to operate, remediation efficiency is high, can be widely used.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
(1) it weighs 400~500g tea seed cake and is put into corundum mortar 100 mesh standard sieves excessively after 1~2h of grinding, obtain tea seed
Cake powder, then tea seed cake powder is put into baking oven, it is taken out after dry 5~6h at 60~70 DEG C, obtains pretreatment tea seed cake powder
End；
(2) above-mentioned pretreated tea seed cake powder and petroleum ether are put into ultrasonic extraction after 1: 3 mixing by solid-to-liquid ratio
Instrument is separated by filtration to obtain filter residue with 200~300W power 20~30min of ultrasonic extraction, with deionized water rinse filter residue 20~
30min obtains degreasing tea seed cake after dry；
(3) by above-mentioned degreasing tea seed cake and anhydrous methanol be by volume 1: 6 mixed after be fitted into Soxhlet extraction device,
60~70 DEG C are heated to, 2~3h of refluxing extraction is kept the temperature with 11~13min/ times rate, collects extracting solution；
(4) said extracted liquid is put into vacuum distillation apparatus, vacuum distillation recycling methanol sprays obtained concentrate
The spray drying of mist drying machine, obtains pale yellow powder, as natural surfactant saponin；
(5) zeolite granular of 200 mesh and natural surfactant saponin obtained above are mixed for 20: 1 in mass ratio
It closes and uniformly obtains enhancing absorption fixative, then enhancing absorption fixative is added to chlorobenzene Polluted Soil for 10~15% by addition content
It in earth, then by soil ratio is 0.3~0.5 deionized water to be added into soil, standing adsorption after mixing of manually digging fixes 1
After~2 weeks.
The beneficial effects of the present invention are:
(1) soil restoring technology of the invention is easy to operate, reaches to chlorobenzene organic contamination species removal rate in soil
95% or more；
(2) soil restoring technology of the invention is compared with the zeolite adsorption immobilization technique for not adding surfactant, soil
Repairing efficiency can shorten 50% or more, have splendid absorption fixed effect.
