Definitions

  • the invention relates to a method and apparatus for treating a fluid containing contaminants to oxidize those contaminants .
  • Biological fluid bed reactors have also been used to treat contaminated fluids.
  • the principles of conventional biological fluid bed treatment processes are described in the following: U.S. Patent No. 3,956,129 issued to Jeris; and, Hickey, R.F., et al, "Combined Biological Fluid Bed - Carbon Adsorption System For BTEX Contaminated Groundwater Remediation.”
  • These processes have several disadvantages .
  • a primary disadvantage of the conventional UV-enhanced oxidation processes is that slow to oxidize organic contaminants, such as saturated organic contaminants, are not cost effectively treated.
  • slow to oxidize organic contaminants require a sufficiently longer hydraulic retention time in order to achieve sufficient contact with the UV-radiation for oxidation of the contaminant to occur.
  • the reactor size needed to achieve the necessary hydraulic retention time is prohibitively expensive.
  • a primary disadvantage of conventional carbon adsorption treatment processes is that the organic contaminants are merely transferred from the fluid medium to the solid carbon medium. The contaminants themselves are not destroyed. Therefore, the contaminated carbon medium must then either be disposed of or regenerated. Disposal of the spent carbon can be costly.
  • a primary disadvantage of conventional biological fluid bed treatment processes is the production of biological sludge which may require additional handling and disposal.
  • the present invention provides a cost effective and efficient method and apparatus for treating fluids containing contaminants, especially contaminated vapors or gases, or wastewaters from industrial processes, contaminated ground waters, municipal wastewater streams and municipal water supplies (raw source waters), by passing the fluid through a bed of particulate adsorbent material capable of adsorbing contaminants from the fluid, preferably granular activated carbon (or GAC), whereby the bed is fluidized and the contaminants are adsorbed on the adsorbent material; and, by oxidizing the contaminants adsorbed on the adsorbent material.
  • a bed of particulate adsorbent material capable of adsorbing contaminants from the fluid, preferably granular activated carbon (or GAC), whereby the bed is fluidized and the contaminants are adsorbed on the adsorbent material; and, by oxidizing the contaminants adsorbed on the adsorbent material.
  • One feature of the invention is the provision of a cost effective and efficient method and apparatus to polish and disinfect municipal wastewater streams and, for potable use, municipal water supplies (raw source waters) , including water contaminated with pesticides .
  • Another feature of the invention is the reduction of operating costs and inefficiency of regeneration associated with conventional adsorption treatment processes by simultaneously regenerating the fluid bed of adsorbent material while treating the fluid containing contaminants .
  • Another feature of the invention is the provision of a method and apparatus capable of effectively treating an expanded list of contaminants, including organic contaminants which are slow to oxidize (such as trichloroethane, dichloroethane, and other saturated organic compounds) by holding the slow to oxidize contaminants on the adsorbent material (such as GAC) until oxidation of the contaminant is complete; including contaminants which are non-biodegradable or difficult to biodegrade (such as trichloroethylene (TCE), perchloroethylene (PCE), pesticides and other synthetic organic compounds); and including other organic and inorganic contaminants, and organisms (such as bacteria, viruses, protozoa, and helminths).
  • organic contaminants which are slow to oxidize such as trichloroethane, dichloroethane, and other saturated organic compounds
  • the adsorbent material such as GAC
  • contaminants which are non-biodegradable or difficult to biodegrade such as trichloroethylene (TCE), perchloroethylene
  • Another feature of the invention is the elimination of contaminated GAC media and biological sludge associated with carbon adsorption and biological fluid beds by destroying the contaminants rather than merely transferring the contaminants to a different medium.
  • Another feature of the invention is the provision of more simple, smaller, and therefore less costly, reactors for treating fluids containing a broad scope of contaminants .
  • Another feature of the invention is the elimination of complex mechanical or chemical cleaning of the quartz sleeve protecting the UV-lamp by providing an inherent cleaning system.
  • the invention provides scouring action of the fluidized bed of particulate material in the reactor to maintain the transparency of the quartz sleeve.
  • Figure 1 is a schematic view of a fluid bed reactor embodying the invention and with portions broken away for clarity.
  • Figure 2 is a view similar to Figure 1 and showing an alternative embodiment of the invention.
  • the invention provides a method and apparatus for treating fluids containing contaminants .
  • the contaminants may be organic (including TCA, DCA, TCE, PCE, polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), pesticides and trihalomethane (THM) precursors and other saturated hydrocarbons), inorganic (including cyanides and hydrogen sulfide), organisms (including various forms of bacteria, protozoa, viruses and helminths), or mixtures thereof.
  • the invention is particularly useful for treating fluids containing organic contaminants .
  • the fluids may be either a gas or a liquid.
  • the invention is especially suitable for treating aqueous liquids such as wastewater from industrial processes (including those processes used by organic chemical manufacturers and users; petroleum refineries; petrochemical industries; wood treating operations; food and beverage companies; pulp and paper industries; pesticide manufacturers and users; and, explosive manufacturers and users), contaminated groundwaters, municipal wastewater streams and municipal water supplies (raw source waters).
  • the invention is especially useful for polishing and disinfecting municipal wastewater streams and, for potable use, municipal water supplies (raw source waters).
  • the invention is also useful for treating, for potable use, water contaminated with pesticides.
  • the application of the invention to wastewater containing organic contaminants will be described below.
  • the wastewater is introduced into a suitable reactor containing a bed of particulate adsorbent material capable of adsorbing the organic contaminants from the wastewater, and capable of being fluidized by the flow of the fluid being treated.
  • Suitable adsorbent materials include granular activated carbon (GAC), powdered activated carbon, activated alumina, mineral clay, zeolite, and mixtures thereof.
  • GAC granular activated carbon
  • the particle size of the adsorbent material is not particularly critical and depends to a large degree upon the size of the reactor, the incoming flow rate of the wastewater, and the desired bed expansion, which will be described in detail below. For instance, for a given reactor size and bed expansion, the preferred particle size will be smaller at a low flow rate and larger at a high flow rate. For example, for a reactor which is 100mm in diameter and about 1 meter tall, a bed expansion of 100%, and a flow rate of 5 gpm, the preferred particle size for the adsorbent material is about 2mm to about 5mm (or about 4 to about 10 mesh).
  • the wastewater is introduced into the reactor in a manner to pass upwardly through the bed of adsorbent material thereby generating a fluidized bed.
  • fluidized bed refers to the flow of the fluid upwardly through the bed of adsorbent material at a velocity sufficient to buoy the adsorbent material, to counter the influence of gravity and to impart to the adsorbent material an appearance of movement within the bed expanded to a greater height than when no flow is passing through the bed.
  • the extent of bed expansion can be about 10% to about 200%, and preferably about 50%.
  • organic contaminants in the wastewater are adsorbed on the adsorbent material thereby removing the organic contaminants from the fluid.
  • the term "adsorbed” as used herein refers to the accumulation of contaminants on the outer or pore surface of the adsorbent material.
  • oxidant is introduced into the fluidized bed to oxidize the organic contaminants adsorbed on the adsorbent material and in the wastewater being treated.
  • oxidant refers to any substance which oxidizes contaminants .
  • oxidize refers to either direct photolysis by UV-radiation, or redox reactions with oxygen containing substances such as ozone, hydrogen peroxide, and/or hydroxyl radicals.
  • Hydroxyl radicals are generated by the reaction of hydrogen peroxide and/or ozone with UV-radiation; in the reaction of ferrous ion with hydrogen peroxide (commonly known as Fenton's reagent) with or without UV-radiation; or, in the reaction of a solid metal photocatalyst such as titanium dioxide with UV-radiation.
  • oxidation refers to the reaction of the contaminants with an oxidant to yield non-harmful or less harmful end products (for example, the reaction of organic contaminants with an oxidant to yield carbon dioxide, water, and miscellaneous salts).
  • the organic contaminants are oxidized by one of several pathways.
  • Readily oxidizable contaminants may be adsorbed by the adsorbent material, or may immediately be oxidized in the fluid before being adsorbed on the adsorbent material.
  • the readily oxidizable contaminants may be oxidized by direct photolysis by the UV-radiation or by hydrogen peroxide, ozone, or the hydroxyl radical. Slow to oxidize contaminants will be adsorbed by the adsorbent material and held in the reactor until the oxidation is complete by any of the pathways described above.
  • the ozone When ozone is used to oxidize the organic contaminants, the ozone is preferably pre-dissolved in the wastewater before being introduced into the reactor. Alternatively, ozone may be generated in the reactor by introducing oxygen into the reactor and exposing the oxygen to UV-radiation.
  • UV-radiation When UV-radiation is used to oxidize the organic contaminants, the UV-radiation is preferably generated by a UV-lamp (or a number of UV-lamps commonly referred to as a bank of lamps).
  • the UV-lamp (or bank of lamps) is selected to produce UV-radiation with a wavelength similar to the wavelength that is most absorbed by the contaminant or mixture of contaminants in the wastewater to be treated or is most absorbed by the chemical oxidant being employed.
  • the UV-lamp (or bank of lamps) may be mounted on the outside of the reactor, or may be disposed within the reactor.
  • a single elongated UV-lamp is centrally located within the fluidized bed of adsorbent material and extends through the height of the bed. This configuration allows the UV-radiation to fully penetrate the wastewater as it passes through the fluidized bed of adsorbent material.
  • the UV-lamp is preferably mounted inside a protective tube of material transparent to UV-radiation to protect the UV-lamp from the wastewater and contaminants. Most preferably, a UV- transmissive quartz sleeve is used as the protective tube.
  • a solid metal photocatalyst When a solid metal photocatalyst is used to generate the hydroxyl radicals, it is fluidized along with the adsorbent material making up the bed.
  • the photocatalyst can be in the form of separate particles mixed and fluidized with the adsorbent material, or the photocatalyst can be impregnated onto GAC. Any suitable method of impregnation can be employed. If the photocataly ⁇ t is impregnated onto GAC, and GAC also functions as the adsorbent material for adsorbing the organic contaminants from the wastewater being treated, then it is important that the adsorption properties of the GAC are not adversely inhibited by the amount of photocatalyst impregnated onto the GAC.

Abstract

On traite un fluide, tel que des vapeurs ou gaz contaminés, ou des eaux usées générées par des processus industriels, de l'eau souterraine contaminée, un flux d'eaux usées d'une agglomération ou une alimentation en eau d'une agglomération (eau de source brute), en faisant passer le fluide à travers un lit (38) de matériau adsorbant particulaire (42), capable d'adsorber des contaminants présents dans le fluide, de préférence du charbon actif granulaire. Le lit est fluidisé par le flux de fluide et les contaminants sont adsorbés sur le matériau adsorbant à mesure que le fluide passe à travers ledit matériau. On introduit dans le lit fluidisé un oxydant tel que des rayonnements UV, du peroxyde d'hydrogène, de l'ozone, de l'oxygène, du réactif de Fenton, des radicaux hydroxyle et des mélanges desdites substances en vue d'oxyder les contaminants adsorbés sur le matériau adsorbant.
