Definitions
- Technological sector The object to which the invention that is protected in this Invention Patent refers is framed in the sector of wastewater treatment systems, specifically between biological treatments.
- the signature holder of the present invention patent is based on the Patents of Invention BR Pl 9301976-9, ES 2 139 483, IT RM1996A000121, NL C 100 31 55, whose object is "Construction provision and operation of a vessel for the treatment of liquid effluents "authored by the same applicant; as well as in the activated sludge process, in fluid dynamics and in limnology.
- the liquid effluent treatment vessel refers to a high-tech equipment associated with verticality, which promotes the recovery of contaminated water, separating contaminants and organic matter added to the liquid, through physical reactions, chemical and biological, induced inside a deep well, called a sanitation well.
- External equipment consists basically of air compressors, process chambers, electrostatic filters and a set of valves electronically operated by an electro-electronic command system.
- the total set is directed and controlled electronically in real time, and its main functions are the permanent supervision of the equipment, the self-diagnosis, simplify maintenance and the alarm system by telemetry avoiding the use of operators. It also provides a safety system to address possible overloads, lack of energy or eventual failure of the command system, guaranteeing the continuity of the process after normalization of the equipment.
- the state of the art of activated sludge processes is characterized by the recirculation of sludge in an aerobic bacterial culture in suspension and with the oxidation of organic matter.
- Limnology explains the biological interactions in aquatic environments, providing information that allows the manipulation of variables in order to achieve a perfect eutrophy in the enveloped ecosystems. This interaction applied to the system has been requested as utility model CO No. 11-066024, by the same author.
- the present invention "Device and technique for digestion of effluents by fluidized beds and limestone filtration”, refers to a system of controlled and scientifically ordered technology, whose determination refers to the application of four reactor tanks arranged and intercommunicated in sequential form
- the tanks are manufactured of concrete or materials resistant to the designated conditions, whose architectural form is determined by individual application conditions and their dimensions are proportional to the flows of wastewater to be handled by the device.
- the first tank is the first stage of the device and is where the process of the present technique begins. This receives the discharge of the raw residual effluent, performs its function and transfers its contents to the second tank, called the sanitation well.
- the sanitation well consists of a deep vertical tank / well that is located at the bottom of the homogenization tank and transfers its result to the third tank, called the decanter tank.
- the decanter tank contains a reactor that promotes the decantation of coarse solids, pouring into the fourth tank called the limestone filter tank.
- the lim ⁇ cola filter tank is the last tank of the device and where the final processes of the technique are performed.
- the four tanks are lightly isolated and independent without external recirculation or fluid return.
- Underground location is recommended allowing the use of external surfaces for other architectural purposes. In this way it promotes the use of contiguous sites and orderly use of spaces.
- Fluid mobilization is a composition of gravitational forces, liquid flows, gas flow and relative weight variation by absorption and / or expulsion of flocks of variable masses.
- the minimum applicability of the system is effluent flows of 2m 3 / day without maximum flow limit. This depends on the number of inhabitants of the same with 50 gallons average of water, which is the daily need per person.
- the homogenizing tank consists of a tank proportional to 40% of the design flow. It is equipped with an aeration system installed at the bottom of the tank, whose power is provided by external compressors, which must provide 14.1 psi at every 10 m of water column. The aerators must meet specifications of the size of the air bubble provided, whose diameter limit cannot exceed 100 pm at 30 m depth.
- This tank has the function of performing the optimum mixture of effluent activation according to hydraulic pressure indices determined by the system's inlet flow. Its aeration is commanded by level floats and flow sensors that control the distribution of air from the compressors.
- Said mixture sows the formation of fluidized beds in the sanitation well, whose deep vertical location and the presence of column aerators arranged at a predetermined distance, allows the stratification of specific biological niches with the possibility of recycling of chemical elements, classified by molecular mass characteristics and biochemical composition.
- the function of this tank is to promote the organic digestion of light solids and separate / transfer heavy solids from the effluent. It has the particular of allowing multiple installation according to the sanitary dimension.
- the effluent from the sanitation tank (s) is transferred to the decanter tank.
- the decanter tank is detentor of an aeration system similar to that of the homogenization tank, with a different function from that in the homogenization tank since they must maintain the stratification by fluidized beds of the sanitation tank inside the settling chamber as well as displace the fluids through communicating holes of the settling reactor in a meandering manner that is arranged vertically.
- the decanter tank allows the installation of several reactors, depending on the need of the design.
- the reactor manages the drain flow of the decanter tank and classifies the combined high-weight solids along the path, allowing their retention and digestion, so that the solids are prevented from being transferred to the limestone filtration tank.
- the pouring of this tank is injected into the bottom of the limestone filter tank through a radial bottom distributor that distributes water evenly throughout the area from the bottom of the tank, causing an upward flow in the fluid to be filtered.
- the radial bottom distributor consists of a conductive water system that is based on gravitational forces in downward flow. The pressure of the receiving column pushes the water through the bottom distribution channels, which is introduced in the lower position of the filter tank, which by inverted percolation occupies the interstitial spaces of the support means, making all the support means humidified properly.
- the lim ⁇ cola filter consists of a tank of tank that is filled with support medium that favors the adhesion of slime and expands the surface of contact water-slime.
- This support medium can be of manufactured materials or of mineral origin and must have a maximum size of 1 in diameter, allowing gradation with smaller diameters at the base of the filling, proportional to the treated flow.
- the surface of the support means must be irregular so as to increase the contact and adhesion surface of silt. Likewise, surface irregularities allow the flow of water through the gap in a filtering manner.
- the silt is adhered to the support medium in a natural condition, which is the result of the integration of the processes of the cycling of matter and flow of energy in which biological, physical and chemical processes characteristic of aquatic environments occur.
- the chemical and biochemical reactions triggered differ in an aerobic surface environment and an anaerobic indoor environment, reflected in agglutination, de-assimilation reduction and fine separation for complete filtration.
- the filtered elements are used in the maintenance of silt and the biotic metabolism of the system.
- Inorganic salts are grouped and mineralized serving as a support medium for new limestone formations.
- the water resulting from the process is collected on the upper surface of the support medium and is taken to the outlet pipe of the system, where air is introduced to recover the condition of saturation of dissolved oxygen in the treated water.
- Figure 1 schematically illustrates a sequential linear perspective of the residual effluent digestion system with: homogenizer tank (A), sanitation well (B), decanter tank (C) and biological filter tank (D).
- Figure 2 presents a sequential transverse perspective of the residual effluent digestion system with: homogenizer tank (A), sanitation well (B), decanter tank (C) and biological filter tank (D).
- Figure 3 illustrates, schematically, a sequential linear perspective inclined at 45 ° from the residual effluent digestion system with: homogenizer tank (A), sanitation well (B), decanter tank (C) and biological filter tank (D) .
- FIG 4 shows, schematically, the decanter reactor (20) with: (21) Upstream communicating hole; (22) Decantation upstream flow pipeline; (23) Decantation downflow pipeline.
- the Reactor Body is appreciated; (b) Reactor Cone; (c) Decantation Holes; (d) Aeration column; (e) Level Controller.
- the process begins in the reception of the effluents in the inlet duct (1) in the homogenization tank (A), which by gravitational force are directed downwards.
- A the homogenization tank
- a rising force results from the bubbles formed by the high pressure air (2), coming from the compressor and distributed by the bottom aerators (7, 8, 9)
- a controlled mixture is formed in the homogenization chamber ( 6).
- the air flow in the aerators is controlled (4) by an input flow sensor device (3) and level float (5), which determine the speed of the mixture according to the contribution of the residual tributary.
- the optimal mixture is directed to the sanitation well (B, 10). It has a series of column aerators (11) at different programmed levels, fixed to the vertical conduit pipe to the decanter tank (13) in its internal part to the sanitation tank, which keep the particles and fluidized beds suspended. In order to avoid damage to the pipe by stress, it is also provided with anti-vibration pallets (12). By forced conduction (13, 15, 17), the effluent is transferred to the decanter chamber (19) with a pressure spillway (14).
- the fluidization of the beds is maintained by the rising bubbles formed by the low pressure air (18), coming from the compressor and distributed by the bottom aerators (7, 8, 9).
- the coarse solids are digested and sedimented, and the water is taken to the decanter reactor (20) by a communicating hole (21) to a winding reactor system of ascending and descending flows (22, 23) until being forced upwards (24 , 25, 27) to the distribution column (28) of the biological filter tank (D), with a pressure relief (14).
- Water injected into the column is distributed in the bottom by conductive systems distributed equally (29). By pressure of the distribution column the water follows an upward flow in the limestone filter chamber (30) through the support means (31), where by gravitational forces the filtered particles tend to remain in the deepest regions of the tank, being metabolized by the limbic ecosystem.
- Water that flows on the surface of the tank is collected by a surface collection system with a downward flow pipe (32) and taken to the exit of the device (33, 34, 35).
