FORMULATO DI NATURA BIOLOGICA E SUO USO PER LA DECONTAMINAZIONE DI MATRICI SOLIDE CONTENENTI CONTAMINANTI ORGANICI RECALCITRANTI ORGANIC FORMULA AND ITS USE FOR THE DECONTAMINATION OF SOLID MATRICES CONTAINING RECALCITRATING ORGANIC CONTAMINANTS
DESCRIZIONE DESCRIPTION
L’invenzione si riferisce alla riduzione del rischio ecologico delle matrici solide contaminate da composti organici difficilmente biodegradabili. The invention refers to the reduction of the ecological risk of solid matrices contaminated by organic compounds that are difficult to biodegrade.
Come à ̈ noto questi contaminanti, superata una determinata concentrazione, condizionano negativamente la fertilità dei suoli, peggiorano la qualità dei prodotti agricoli, inquinano le acque sotterranee, e possono costituire un grave pericolo per la saluta umana e per l’ambiente. As it is known, these contaminants, exceeding a certain concentration, negatively affect soil fertility, worsen the quality of agricultural products, pollute groundwater, and can constitute a serious danger to human health and the environment.
La casistica dei suoli contaminati à ̈ molto variegata. Assai spesso essi sono identificabili: The case history of contaminated soils is very varied. Very often they are identifiable:
• nelle aree industriali attive o dismesse, • nelle aree utilizzate per lo smaltimento rifiuti, â € ¢ in active or abandoned industrial areas, â € ¢ in areas used for waste disposal,
• nei siti militari. â € ¢ at military sites.
A queste tipologie di contaminazione vanno poi aggiunte le contaminazioni dei suoli in maniera diffusa, in cui l’inquinamento può essere associato: To these types of contamination must then be added the contamination of soils in a widespread manner, in which pollution can be associated:
• alla deposizione atmosferica â € ¢ to atmospheric deposition
• a determinate pratiche agricole â € ¢ to certain agricultural practices
• a inadeguate operazioni di riciclo dei rifiuti e trattamento delle acque reflue. â € ¢ inadequate waste recycling and wastewater treatment operations.
I procedimenti finora utilizzati per rimuovere la contaminazione da composti organici tossici non sono del tutto soddisfacenti per ragioni ecologiche, economiche e tecnologiche. The processes used up to now to remove contamination from toxic organic compounds are not entirely satisfactory for ecological, economic and technological reasons.
Ad esempio, le tecniche di trattamento dei suoli basate su processi chimico-fisici, tendono a spostare la contaminazione dalla matrice suolo, verso un altro veicolo in grado di trasportarla – in genere acqua o soluzioni acquose contenenti additivi in grado di agevolare la migrazione del contaminante dal terreno alla fase acquosa. For example, soil treatment techniques based on chemical-physical processes tend to move the contamination from the soil matrix to another vehicle capable of transporting it - generally water or aqueous solutions containing additives capable of facilitating migration of the contaminant from the soil to the aqueous phase.
Alcune di queste tecnologie di trattamento possono inoltre creare dei sottoprodotti, la cui pericolosità può essere superiore a quella dell’inquinante originale. Some of these treatment technologies can also create by-products, the dangerousness of which may be higher than that of the original pollutant.
Ad ogni modo, l’efficacia delle tecnologie sopra indicate à ̈ soddisfacente nei confronti di tipologie di contaminanti quali: In any case, the effectiveness of the technologies indicated above is satisfactory against types of contaminants such as:
• idrocarburi â € ¢ hydrocarbons
• composti alogenati organici â € ¢ organic halogen compounds
• BTEX (Benzene, Toluene, Etilbenzene e Xileni ) â € ¢ BTEX (Benzene, Toluene, Ethylbenzene and Xylenes)
e in generale verso inquinanti di natura organica non recalcitrante. and in general towards non-recalcitrant organic pollutants.
Quando invece i contaminanti sono: When instead the contaminants are:
• IPA (Idrocarburi Policiclici Aromatici) â € ¢ PAH (Polycyclic Aromatic Hydrocarbons)
• PCB (Policlorobifenili) â € ¢ PCB (Polychlorinated biphenyls)
• diossine e furani, â € ¢ dioxins and furans,
le tecnologie di trattamento basate su processi meccanici e/o chimico–fisici molto spesso non sono efficaci. treatment technologies based on mechanical and / or chemical - physical processes are very often not effective.
Esiste pertanto nello specifico settore l’esigenza di disporre di una migliorata tecnologia per l’abbattimento e la riduzione del rischio ecologico delle matrici solide, contaminate da composti organici tossici e difficilmente biodegradabili. Therefore, there is a need in the specific sector to have an improved technology for the abatement and ecological risk reduction of solid matrices, contaminated by toxic organic compounds and difficult to biodegrade.
La presente invenzione consente di superare tutti gli inconvenienti incontrati con le tecnologie note, offrendo inoltre ulteriori vantaggi, come risulterà evidente nel seguito. The present invention allows to overcome all the drawbacks encountered with known technologies, offering further advantages, as will be evident in the following.

Il procedimento secondo la presente invenzione comprende le seguenti operazioni: aggiungere il formulato sopra descritto alla matrice da trattare; mescolare fino ad ottenere un miscuglio omogeneo; e lasciare agire i microrganismi del formulato nel miscuglio omogeneo per un tempo sufficiente ad ottenere la decontaminazione nella misura desiderata. The invention also relates to a process to remove recalcitrant organic contaminants from solid matrices and to reclaim soils, soils and solid matrices in general. The process according to the present invention comprises the following operations: adding the formulation described above to the matrix to be treated; mix until a homogeneous mixture is obtained; and allowing the microorganisms of the formulation to act in the homogeneous mixture for a time sufficient to obtain decontamination to the desired extent.
