"Mobile plant for the treatment of run-off rainwater, contaminated groundwater and alluvial or accidental flood water" The present invention relates to a mobile plant for the treatment of runoff rainwater, contaminated groundwater and alluvial flood water or accidental.

Scopo dell'invenzione è di realizzare un impianto mobile per il trattamento di acque meteoriche di dilavamento che si accumulano nelle aree urbanizzate a seguito di intense precipitazioni e di acqua di falda contaminata. The object of the invention is to provide a mobile plant for the treatment of run-off rainwater which accumulates in urbanized areas following intense precipitation and contaminated groundwater.

Tale scopo è raggiunto secondo l'invenzione con un impianto mobile per il trattamento di acque meteoriche caratterizzato dal fatto di comprendere in un container: This object is achieved according to the invention with a mobile plant for the treatment of rainwater characterized in that it comprises in a container:

- una pompa autoadescante, - a self-priming pump,

- un serbatoio polmone di un liquido combustibile, - a buffer tank for a combustible liquid,

- una vasca di filtrazione contenente una pluralità di unità filtranti, - a filtration tank containing a plurality of filtering units,

- un condotto di carico della pompa e di scarico da questa nella vasca di filtrazione, - a pipe for loading the pump and discharging it into the filtration tank,

- condotti di scarico dell’acqua in uscita dalle unità filtranti, - water drainage pipes leaving the filter units,

- sonde di rilevamento poste nel condotto di scarico dell’acqua, - detection probes placed in the water discharge duct,

- una centralina alimentata a batterie di gestione dei dati provenienti dalle sonde. - a battery-powered control unit for managing data from the probes.

La presente invenzione viene qui di seguito ulteriormente chiarita in una sua preferita forma di pratica realizzazione riportata a scopo puramente semplificativo e non limitativo con riferimento alle allegate tavole di disegni in cui: The present invention is further clarified hereinafter in a preferred embodiment thereof reported for purely simplifying and non-limiting purposes with reference to the attached drawing tables in which:

la figura 1 mostra in vista laterale un impianto secondo l’invenzione, Figure 1 shows a side view of a plant according to the invention,

la figura 2 lo mostra in vista frontale, Figure 2 shows it in front view,

la figura 3 mostra in vista prospettica una cartuccia filtrante. Figure 3 is a perspective view of a filter cartridge.

Come si vede dalle figure rimpianto mobile secondo l’invenzione comprende sostanzialmente un container normalizzato 2 in acciaio, trattato con specifici cicli di verniciatura all’interno del quale sono alloggiate una pompa autoadescante 4 con un serbatoio polmone di gasolio 6 ed una vasca 8 di filtrazione nella quale sono disposte una pluralità di unità filtranti 10. As can be seen from the figures, the mobile unit according to the invention substantially comprises a standardized container 2 in steel, treated with specific painting cycles inside which a self-priming pump 4 with a diesel fuel tank 6 and a filtration tank 8 are housed in which a plurality of filtering units 10 are arranged.

La pompa 4 ha un’elevata capacità di aspirazione ed è provvista di sistemi di sicurezza integrati: inoltre è possibile gestire la portata di acqua inviata alla vasca di trattamento per mezzo di una valvola e in funzione dei volumi da aspirare e del livello di contaminazione da rimuovere. Pump 4 has a high suction capacity and is equipped with integrated safety systems: it is also possible to manage the flow of water sent to the treatment tank by means of a valve and according to the volumes to be sucked and the level of contamination to be to remove.

II serbatoio 6 del gasolio è ancorato al fondo del container 2 che in corrispondenza del vano pompa è abbassato di circa 10 cm in modo da aumentare l’altezza sfruttabile all’interno del container e creare una vasca di contenimento in grado di arginare perdite di gasolio dal serbatoio della pompa o dal serbatoio supplementare. The diesel fuel tank 6 is anchored to the bottom of the container 2 which in correspondence with the pump compartment is lowered by about 10 cm in order to increase the usable height inside the container and create a containment tank capable of stemming diesel oil leaks. from the pump tank or from the additional tank.

L’interno del vano pompa alloggia altresì la centralina alimentata tramite pannello fotovoltaico e relative batterie per il rilevamento dei dati provenienti da tre sonde per la determinazione della torbidità, del pH e della conducibilità, poste sul condotto di scarico 12 della vasca. Tale sistema è in grado di effettuare un controllo continuo sulla qualità delle acque scaricate, di registrare i dati raccolti in un data - log e di inviarli tramite gsm ad un server permettendo la verifica continua dell’efficienza del sistema. Il sistema di controllo e monitoraggio è, inoltre, dotato di un sistema di emergenza che in presenza di anomalia allo scarico, blocca il sistema di aspirazione ed invia il segnale di allarme a mezzo gsm. The interior of the pump compartment also houses the control unit powered by a photovoltaic panel and related batteries for the detection of data from three probes for the determination of turbidity, pH and conductivity, placed on the drain pipe 12 of the tank. This system is able to carry out a continuous control on the quality of the discharged water, to record the data collected in a data - log and to send them via GSM to a server allowing the continuous verification of the efficiency of the system. The control and monitoring system is also equipped with an emergency system which, in the presence of an anomaly in the exhaust, blocks the intake system and sends the alarm signal via gsm.

Ciascuna unità filtrante 10 comprende sostanzialmente un cappuccio cilindrico 14 che alloggia al suo interno una struttura a rete 16 di supporto. In particolare i materiali filtranti possono essere costituiti da perlite, zeolite, carboni attivi, phosphosorb, ecc. Each filtering unit 10 substantially comprises a cylindrical cap 14 which houses inside it a support mesh structure 16. In particular, the filter materials can consist of perlite, zeolite, activated carbon, phosphosorb, etc.

Il materiale filtrante avvolge un tubo 18 interessato da una pluralità di fori 20 e provvisto superiormente di un tappo 22 con valvola di sfiato 24. The filtering material wraps around a tube 18 affected by a plurality of holes 20 and provided at the top with a cap 22 with a vent valve 24.

All’interno del tubo 18 è disposto un galleggiante sagomato 26 la cui estremità inferiore chiude, in assenza di acqua all’interno della vasca, un foro 28 previsto sul fondo 30 della vasca stessa. Inside the tube 18 there is a shaped float 26 whose lower end closes, in the absence of water inside the tank, a hole 28 provided on the bottom 30 of the tank itself.

In posizione sottostante al fondo ed affacciati ai fori 28 sono previste canale 32 di raccolta dell’acqua che fanno capo al collettore comune di scarico 12. In a position below the bottom and facing the holes 28, water collection channels 32 are provided which refer to the common discharge manifold 12.

All’interno della vasca 8 ed in corrispondenza di una parete di questa è prevista una parete divisoria 34 costituente un troppo pieno per l’acqua della vasca. Inside the tank 8 and in correspondence with a wall of this there is a dividing wall 34 constituting an overflow for the water of the tank.

Il funzionamento dell’impianto secondo l’invenzione è il seguente: l’acqua di dilavamento aspirata dalla pompa viene versata all’interno della vasca. The operation of the system according to the invention is as follows: the washout water sucked by the pump is poured into the tank.

Man mano che l’acqua entra all’interno della vasca essa sale nella intercapedine anulare formata dal cappuccio 14 e dalla struttura a rete 16 di ciascuna unità filtrante per entrare attraverso i fori 20 all’interno del tubo 18. As the water enters the tank it rises into the annular cavity formed by the cap 14 and the mesh structure 16 of each filter unit to enter through the holes 20 inside the tube 18.

Allo stesso tempo l’aria contenuta nella parte superiore del galleggiante viene fatta uscire attraverso la valvola di sfiato 26 e quando il tubo centrale si è riempito il galleggiante si solleva lasciando libero il foro 28 sul fondo della vasca e permettendo all’acqua trattata di essere scaricata all’interno delle canale 32. At the same time the air contained in the upper part of the float is let out through the vent valve 26 and when the central tube is filled the float rises leaving the hole 28 on the bottom of the tank free and allowing the treated water to be discharged into channel 32.

L’uscita dell’acqua filtrata fa sì che l’aria entri nella cartuccia e conseguentemente la valvola si chiude ed inizia un effetto sifone che trascina via tutta l’acqua inquinata dall’interno delle masse filtranti. The outlet of the filtered water causes the air to enter the cartridge and consequently the valve closes and a siphon effect begins which drags away all the polluted water from inside the filtering masses.

Questo processo continua fino a che il livello dell’acqua scende al di sotto dei regolatori di sfiato e viene qui cessa l’effetto sifone. This process continues until the water level drops below the vent regulators and here the siphon effect ceases.

L’aria viene velocemente sospinta tra la parete interna del cappuccio e la parte esterna del filtro e questo crea una forte turbolenza fra le due superfici con il conseguente rilascio dei sedimenti accumulati che vanno a depositarsi sul fondo dell’alloggiamento. The air is quickly pushed between the internal wall of the hood and the external part of the filter and this creates a strong turbulence between the two surfaces with the consequent release of accumulated sediments that go to deposit on the bottom of the housing.

La presente invenzione è stata illustrata e descritta in una sua preferita forma di pratica realizzazione, ma si intende che varianti esecutive potranno ad essa in pratica apportarsi, senza peraltro uscire daN'ambito di protezione del presente brevetto per invenzione industriale. The present invention has been illustrated and described in a preferred embodiment thereof, but it is understood that executive variations may be applied to it in practice, without however departing from the scope of protection of the present patent for industrial invention.
