Description

La présente invention concerne une composition de matière pour l'épuration chimique, physique et biologique des liquides aqueux pollués, cette composition étant destinée à être répandue dans le liquide aqueux à épurer. The present invention relates to a composition of matter for the chemical, physical and biological purification of polluted aqueous liquids, this composition being intended to be spread in the aqueous liquid to be purified.

Le brevet FR-A-2 650 265 appartenant aux présents déposants décrit une composition minérale et biologique destinée à être répandue dans l'eau à épurer, permettant notamment l'épuration et la dégradation des rejets fermentescibles urbains, industriels, agroalimentaires, solides ou liquides, les pollutions accidentelles, l'entrophysation et la destrophysation des rivières, des étangs et la prévention des pollutions cidessus. Patent FR-A-2 650 265 belonging to the present applicants describes a mineral and biological composition intended to be spread in the water to be purified, in particular allowing the purification and the degradation of fermentable discharges from urban, industrial, food, solid or liquid , accidental pollution, entrophysation and destrophysation of rivers, ponds and the prevention of pollution above.

Cette composition de matière, destinée à être répandue dans l'eau à épurer est caractérisée en ce qu'elle comprend au moins les deux matières minérales suivantes, sous forme granulaire
- un carbonate de calcium poreux, riche en oligo-éléments,
- un silicate d'alumine hydraté renfermant des métaux alcalino-terreux, ces deux matières renfermant à l'état adsorbé des bactéries spécifiques pour la dégradation biologique des matières organiques à chaine carbonée.This composition of matter, intended to be spread in the water to be purified is characterized in that it comprises at least the following two mineral materials, in granular form
- a porous calcium carbonate, rich in trace elements,
- a hydrated alumina silicate containing alkaline earth metals, these two materials containing, in the adsorbed state, specific bacteria for the biological degradation of organic materials containing a carbon chain.

La première matière, c'est-à-dire le carbonate de chaux, présente une grande porosité et donc une grande surface de contact favorable aux échanges ioniques avec le milieu à épurer. The first material, that is to say lime carbonate, has a high porosity and therefore a large contact surface favorable to ionic exchanges with the medium to be purified.

Cette matière est capable
- de transformer le phosphate soluble contenu dans le milieu pollué en phosphate tricalcique insoluble,
- d'abaisser la teneur en fluor et en magnésium du milieu pollué,
- d'agir sur la dureté de l'eau et la radioactivité de celle-ci,
- d'adsorber une grande quantité de bactéries dont l'activité biologique aura un pouvoir tampon important (pH) tout en dégradant la matière organique, notamment les hydrocarbures contenus dans l'eau polluée, et
- de participer ainsi à l'équilibre phytoplancton-zooplancton, au profit de ce dernier.This material is capable
to transform the soluble phosphate contained in the polluted medium into insoluble tricalcium phosphate,
- lower the fluorine and magnesium content of the polluted medium,
- to act on the hardness of the water and its radioactivity,
to adsorb a large quantity of bacteria whose biological activity will have a significant buffering capacity (pH) while degrading the organic matter, in particular the hydrocarbons contained in the polluted water, and
- thus participate in the phytoplankton-zooplankton balance, for the benefit of the latter.

La deuxième matière, constituée par un silicate d'alumine hydraté permet de piéger les ions ammonium contenus dans l'eau polluée qui sont transformés en molécules inoffensives par les bactéries adsorbées dans la matière. The second material, consisting of a hydrated alumina silicate, makes it possible to trap the ammonium ions contained in the polluted water which are transformed into harmless molecules by the bacteria adsorbed in the material.

Comme le premier matériau, le deuxième matériau ci-dessus constitue un véritable abri pour les bactéries. Like the first material, the second material above provides real shelter for bacteria.

Ce deuxième matériau permet également d'adsorber par échange ionique certains métaux lourds contenus dans le milieu pollué.This second material also makes it possible to adsorb by ion exchange certain heavy metals contained in the polluted medium.

Selon une version préférée, la composition renferme en outre un silicate d'alumine potassique anamorphosé. According to a preferred version, the composition also contains an anamorphosed potassium alumina silicate.

Le but de la présente invention est d'accroître encore davantage l'efficacité de la composition décrite dans le brevet FR-A-2 650 265. The object of the present invention is to further increase the effectiveness of the composition described in patent FR-A-2,650,265.

L'invention vise ainsi une composition de matière pour l'épuration chimique, physique et biologique des liquides aqueux pollués, cette composition étant destinée à être répandue dans le liquide à épurer et comprenant au moins les deux matières minérales suivantes, sous forme granulaire
- un carbonate de calcium poreux, riche en oligo-éléments,
- un silicate d'alumine hydraté renfermant des métaux alcalino-terreux,
ces matières renfermant à l'état adsorbé des bactéries spécifiques pour la dégradation biologique des matières organiques à chaîne carbonée.The invention thus relates to a composition of matter for the chemical, physical and biological purification of polluted aqueous liquids, this composition being intended to be spread in the liquid to be purified and comprising at least the following two mineral materials, in granular form
- a porous calcium carbonate, rich in trace elements,
- a hydrated alumina silicate containing alkaline earth metals,
these materials containing, in the adsorbed state, specific bacteria for the biological degradation of organic materials with a carbon chain.

Suivant l'invention, cette composition est caractérisée en ce que lesdites matières renferment en outre, à l'état adsorbé au moins une enzyme apte notamment à accélérer l'hydrolyse de la dextrine. According to the invention, this composition is characterized in that said materials also contain, in the adsorbed state at least one enzyme capable in particular of accelerating the hydrolysis of dextrin.

La présence d'enzymes au sein de la composition de matière permet d'accélérer l'hydrolyse de la dextrine entourant les cellules bactériennes ou alguaires, composant les filaments, qui se développent en circuit hydraulique, ouvert ou fermé. The presence of enzymes within the composition of matter makes it possible to accelerate the hydrolysis of the dextrin surrounding the bacterial or algal cells, composing the filaments, which develop in hydraulic circuit, open or closed.

Ces enzymes permettent, en plus de réduire les développements alguaires par action biochimique et enzymatique sur la membrane des micro-algues, de former une diastase filmogène inhibitrice à la surface des matériaux traités afin d'éviter un nouveau dépôt organique. These enzymes make it possible, in addition to reducing algal development by biochemical and enzymatic action on the membrane of micro-algae, to form an inhibiting film-forming diastase on the surface of the treated materials in order to avoid new organic deposition.

L'effet du traitement est d'éviter l'attaque des sulfato-réductrices et d'apporter une protection anti-corrosion. The effect of the treatment is to avoid the attack of the sulphate-reducing agents and to provide anti-corrosion protection.

Par sa composition chimique, l'équilibre calcocarbonique favorisera l'effet du produit et servira de tampon (pH). By its chemical composition, the calcocarbonic balance will favor the effect of the product and will serve as a buffer (pH).

Le dépôt filmogène et passif empêchera également l'accrochage des animalcules et autres mollusques à la surface desdits matériaux. The film-forming and passive deposit will also prevent the attachment of animalcules and other molluscs to the surface of said materials.

L'application sera faite au système d'alimentation des circuits hydrauliques et placée selon les conseils des techniciens. The application will be made to the supply system of the hydraulic circuits and placed according to the advice of the technicians.

De préférence, l'enzyme présente dans la composition de matière est une cellulase et/ou une dextrase et/ou une protéase. Preferably, the enzyme present in the composition of matter is a cellulase and / or a dextrase and / or a protease.

De préférence également, lesdites matières renferment à l'état adsorbé entre environ 10/a0 et 1% unités, gramme d'enzymes par gramme de matière.  Preferably also, said materials contain in the adsorbed state between approximately 10 / a0 and 1% units, gram of enzymes per gram of material.

Le procédé de préparation de la composition conforme à l'invention est analogue à celui décrit dans le brevet FR-A-2 650 265. The process for preparing the composition according to the invention is analogous to that described in patent FR-A-2,650,265.

Il comprend ainsi les étapes suivantes
- on inocule à une température comprise entre 25 et 370C les bactéries sur un milieu de culture approprié,
- on soumet le milieu de culture inoculé à une ultracentrifugation, de façon à concentrer le milieu concentré en bactéries dans le mélange desdites matières minérales sous forme granulaire, et
- on sèche l'ensemble à une température inférieure à 400C.It thus includes the following steps
- the bacteria are inoculated at a temperature between 25 and 370C on an appropriate culture medium,
the inoculated culture medium is subjected to ultracentrifugation, so as to concentrate the medium concentrated in bacteria in the mixture of said mineral materials in granular form, and
- the whole is dried at a temperature below 400C.

Conformément à la présente invention, on ajoute au moins une enzyme au milieu destiné à l'hydrolyse de la dextrine et cellulose. In accordance with the present invention, at least one enzyme is added to the medium intended for the hydrolysis of dextrin and cellulose.

Ce procédé permet ainsi d'adsorber les enzymes en même temps que les bactéries au sein des microcavités des particules de substances minérales. This process thus makes it possible to adsorb the enzymes at the same time as the bacteria within the microcavities of the particles of mineral substances.

Du fait que ces enzymes sont adsorbées dans ces microcavités, elles se libèrent progressivement pour produire leurs effets vis-à-vis du milieu à épurer. Ces enzymes restent ainsi efficaces pendant une longue durée. Because these enzymes are adsorbed in these microcavities, they are gradually released to produce their effects vis-à-vis the medium to be purified. These enzymes thus remain effective for a long time.

L'invention vise également le procédé pour l'épuration chimique, physique et biologique des liquides aqueux pollués. The invention also relates to the process for the chemical, physical and biological purification of polluted aqueous liquids.

Selon l'invention, on répand sur le liquide à épurer une composition de matière du type décrit cidessus. According to the invention, a composition of material of the type described above is spread over the liquid to be purified.

Conformément à la présente invention, on ajoute périodiquement au liquide à épurer, un additif liquide renfermant ladite enzyme. In accordance with the present invention, a liquid additive containing said enzyme is periodically added to the liquid to be purified.

De préférence, on ajoute ladite composition de matière à l'eau à épurer, à raison d'environ 100g de composition par m3 d'eau consommée dans une journée.  Preferably, said composition of matter is added to the water to be purified, at the rate of approximately 100 g of composition per m3 of water consumed in a day.

De préférence également, on ajoute l'additif liquide renfermant ladite enzyme, tous les 8 à 10 jours, à raison de 2 à 5 ml d'additif liquide renfermant entre 10/00 et 1% unités-gramme d'enzymes, par m3 d'eau consommée dans une journée. Preferably also, the liquid additive containing said enzyme is added every 8 to 10 days, at a rate of 2 to 5 ml of liquid additive containing between 10/00 and 1% gram units of enzymes, per m3 d water consumed in a day.

On décrit ci-après un exemple d'application de la composition conforme à l'invention. An example of application of the composition according to the invention is described below.

La composition est placée dans le système d'alimentation du circuit hydraulique, dans la bâche de retenue des eaux ou dans le filtre d'épuration à raison de 100 g/m3 et par jour. The composition is placed in the supply system of the hydraulic circuit, in the water holding tank or in the purification filter at a rate of 100 g / m3 and per day.

L'entretien se fera par l'introduction de l'additif liquide tous les 8 à 10 jours. The maintenance will be done by the introduction of the liquid additive every 8 to 10 days.

L'introduction totale de l'additif se fera à raison de 1 litre par heure minimum. The total introduction of the additive will be at a rate of 1 liter per hour minimum.

La quantité totale sera introduite en amont de la canalisation, de préférence dans la bâche. The total quantity will be introduced upstream of the pipeline, preferably in the tarpaulin.

Les effets de la composition se révéleront dans les 3 à 4 jours de la mise en place dans le système. The effects of the composition will be revealed within 3 to 4 days of being placed in the system.

CONCENTRATION D'UTILISATION - TRAITEMENT PRIMAIRE
On remplit le filtre ou on verse dans la bâche de retenue, une quantité de produit qui ne sera pas inférieure à 100 g/m3 d'eau consommée à la journée.CONCENTRATION OF USE - PRIMARY TREATMENT
The filter is filled or poured into the holding tank, a quantity of product which will not be less than 100 g / m3 of water consumed per day.

ENTRETIEN
Le contrôle se fera tous les mois, l'usure n'étant que chimique (pH acide) ou mécanique (abrasion).INTERVIEW
The control will be done every month, the wear being only chemical (acid pH) or mechanical (abrasion).

On surveillera la concentration du produit afin de garder son niveau optimum d'oxygène. En général, une addition devra se faire 2 fois par an. L'usure du produit est surtout en fonction de la dureté de l'eau utilisée. The concentration of the product will be monitored to keep its optimum level of oxygen.
