Abstract
The invention discloses a novel environment-friendly reagent for reducing leaching concentration of various heavy metals. The formula of the environment-friendly reagent comprises 0-30wt% of sodium polysulfide, 1-25wt% of sodium silicate, 0-15wt% of organic sulfur TMT-15, 0-20wt% of hydrazine hydrate, 1-20wt% of phosphate, 1-10wt% of sodium sulphide, 0-15wt% of ferrous sulfate, 0-5% of potassium permanganate, 0-5wt% of citric acid and 0-5wt% of edetic acid (EDTA). The novel environment-friendly reagent can be applied to ex-situ remediation of the traditional hazardous waste containing the heavy metals, and can also be applied to in-situ remediation of pollution site soil and underground water containing the heavy metals.
Description
Technical field
The present invention relates to a kind of novel environment friendly medicament that reduces various heavy leaching concentration.
Background technology
The situation is tense in heavy metal contamination at present, and it is administered and becomes current instant problem.The leaching concentration that adopts stabilization agent to reduce the heavy metal in soil and all kinds of danger wastes is considered to a kind of effective restorative procedure, almost account for the 20-30% of all heavy metal contamination class rehablitation projects, so the use of stabilization agent becomes the key factor of this technology.Chemically stable general theory of law is by add chemically stable medicament in pollutent, makes it and pollutent generation chemical reaction, allows free state heavy metal form stable material and loses toxicity.This method is had relatively high expectations to chemical agent.For a long time, most chemically stable medicaments can only continue some months even several days to the stabilising effect of soil, cannot ensure that the compound producing after administering can exist in nature long-term stability, when environmental change, heavy metal is easily reactivated, and produces secondary pollution.
Simultaneously, the stabilization agent that Present Domestic and world market produce is mainly solid powder medicament, use pressed powder to repair medicament and also have following shortcoming: while 1. adopting powder medicine to process contaminated soil, medicament and mixing with soil time are longer, homogeneity is poor, additive amount of medicament is larger, and curing time is relatively long.2. powder medicine, for heavy metal soil treatment, can only adopt showering conventionally, and owing to adopting showering, quantities is large, and engineering time is long, and rehabilitation cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of novel environment friendly medicament that reduces various heavy leaching concentration, can be used for traditional showering containing heavy metal danger wastes, also can be used for the original position reparation containing heavy metal contamination place soil and underground water.
A kind of novel environment friendly medicament that reduces various heavy leaching concentration, the formula of described environmental protection medicament is: the organosulfur TMT-15 of the water glass of 0-30wt% sodium polysulphide, 1-25wt%, 0-15wt%, 0-20wt% hydrazine hydrate, 1-20wt% phosphoric acid salt, 1-10wt% sodium sulphite, 0-15wt% ferrous sulfate, 0-5% potassium permanganate, 0-5wt% citric acid and 0-5wt% ethylenediamine tetraacetic acid (EDTA) (EDTA).
Described phosphoric acid salt is one or more mixing in sodium phosphate, SODIUM PHOSPHATE, MONOBASIC, Secondary ammonium phosphate or Sodium phosphate dibasic.
The formula of described environmental protection medicament can, according to the difference of contaminated soil character, add 1-5wt% tensio-active agent.
Promoting agent of the present invention refers to anion surfactant (Alkyl sulfide hydrochlorate, alkylsulfonate (as Sodium dodecylbenzene sulfonate), the mixture of one or more in base benzene sulfonate (as Sodium dodecylbenzene sulfonate)) or nonionogenic tenside (containing alkylphenol polyoxyethylene type nonionogenic tenside, long chain aliphatic alcohol Polyoxyethylene elher surfactant, the mixture of one or more in polyoxyethylene carboxylate type nonionogenic tenside).
The present invention has the following advantages:
1, simplify repairing construction technique: while adopting liquid preparation to carry out heavy-metal contaminated soil and underground water reparation, can adopt original position repair mode, adopt professional equipment that medicament is injected to contaminated soil and underground water or carry out original position and stir enforcement, also adopt showering mode, mix more even, reduce the usage ratio of medicament, improve repairing effect.
2, simplify medicament production technique: liquid preparation can carry out scene preparation according to the contamination class of on-site soil, pollution level, avoided simultaneously stabilization repair pulvis fixedly medicament composition be difficult to adapt to the shortcoming of contamination class, pollution level variation.
embodiment
In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
A kind of novel environment friendly medicament that reduces various heavy leaching concentration of the present invention, the formula of described environmental protection medicament is: the organosulfur TMT-15 of the water glass of 0-30wt% sodium polysulphide, 1-25wt%, 0-15wt%, 0-20wt% hydrazine hydrate, 1-20wt% phosphoric acid salt, 1-10wt% sodium sulphite, 0-15wt% ferrous sulfate, 0-5% potassium permanganate, 0-5wt% citric acid and 0-5wt% ethylenediamine tetraacetic acid (EDTA) (EDTA).
Described phosphoric acid salt is one or more mixing in sodium phosphate, SODIUM PHOSPHATE, MONOBASIC, Secondary ammonium phosphate or Sodium phosphate dibasic.
The formula of described environmental protection medicament can, according to the difference of contaminated soil character, add 1-5wt% tensio-active agent.
This concrete situ repair process of implementing can carry out respectively soil and the stirring of medicament original position according to place situation, or the mode of original position injection.
The original position of contaminated soil and medicament stirs specific implementation process: by original position, stirs injection equipment and realize that edaphic original position stirs and injection is carried out simultaneously, and stir, realize fully mixing of medicament and soil completely, assurance soil underground water repairing effect.During concrete enforcement, adopt original position stirring drill tool to creep into and churning oxidation medicament, when creeping into, starts by composite stirring drilling tool grouting pump downwards simultaneously, pumping chemical oxidation medicament is to hole, churning limit, limit is stirred and is polluted the soil body to designing end absolute altitude, and up and down reciprocatingly creep into a circulation, when drilling tool lifting stops pumping medicament and stirring during to ground.By this kind of technique, inhomogeneous contaminated soil can be broken up to mixing, increase the perviousness of soil, and guarantee that soil fully mixes and contacts with medicament, reach the original position stabilization of contaminated soil.
Original position is injected specific implementation process: by contaminated site hydrogeology situation, the character of pollutent and the detailed analysis of pollution condition, adopt three kinds of multi-form Injection Wells that contaminated soil is divided into three layers of improvement.Wherein, fill stratum mainly arranges horizontal Injection Well; Watertight layer mainly arranges vertical injection shallow well, and micro-confined aquifer takes the mode of vertically injecting deep-well to inject.Adopt if desired sleeve pipe technique to prevent crossed contamination.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
