    摘要： Developer-containing waste water is subjected to a multi-stage biological treatment. A waste water treatment apparatus for carrying out a two-stage biological treatment has an adjustment tank for receiving raw waste water and for preliminarily adjusting water quality of the waste water. First and second contact aeration tanks are used to biologically treat the waste water. First and second settling tanks are connected to the first and second contact aeration tanks for separating by sedimentation sludge from the waste water. Specifically, the first settling tank is connected to the second contact aeration tank. Sludge separated from the waste water is returned from the first and second settling tanks to first and second mixing tanks, respectively, and mixed with Bacillus Subtilis Kubota (BSK) and excess household sludge. The mixture is aerated and then transferred to the first and second contact aeration tanks, respectively. The aerated mixture in the first mixing tank is also transferred to the adjustment tank in accordance with the water quality of the raw waste water.

    摘要： An apparatus and method for in situ remediation of contaminated subsurface soil or groundwater contaminated by chlorinated hydrocarbons. A nutrient fluid is selected to stimulate the growth and reproduction of indigenous subsurface microorganisms that are capable of degrading the contaminants; an oxygenated fluid is selected to create a generally aerobic environment for these microorganisms to degrade the contaminants, leaving only pockets that are anaerobic. The nutrient fluid is injected periodically while the oxygenated fluid is injected continuously and both are extracted so that both are drawn across the plume. The nutrient fluid stimulates microbial colony growth; withholding it periodicially forces the larger, healthy colony of microbes to degrade the contaminants. Treatment is continued until the subsurface concentration of contaminants is reduced to an acceptable, preselected level. The nutrient fluid can be methane and the oxygenated fluid air for stimulating production of methanotrophs to break down chlorohydrocarbons, especially trichloroethylene (TCE) and tetrachloroethylene.

    摘要： Regulated processes for biodegrading halogenated organic compounds in an aqueous subsurface environment through stimulation of bacteria are provided. The processes provide an electron donor source to anaerobic dehalogenating bacteria as a stimulus for biodegradation of the contaminants. When necessary to limit the biological formation of vinyl halide monomer, the processes provide for a sulfate reducing environment in the region of biological activity by the addition of an inorganic sulfate. One embodiment provides for converting the aqueous subsurface environment from anaerobic dehalogenating conditions to aerobic conditions. Another embodiment provides for converting the aqueous subsurface environment from anaerobic dehalogenating conditions to anaerobic methanogenic conditions followed by conversion to aerobic conditions in order to completely degrade the contaminants to carbon dioxide and water.

    摘要： A method for improved slurry-phase bioremediation treatment of organic sludge and mixtures of organic sludge and organics-contaminated soils by dissolving the contaminants into an aqueous phase and microbially degrading same. A high solids slurry of the sludge and soils is formed with water and an active bioslurry consisting of large populations of acclimated hydrocarbon-utilizing bacteria and small amounts of biodegradation residue. The slurry is passed through a plurality of in-series bioreactors in each of which a low hydraulic shear is maintained to promote the development of a large population of microorganisms that will form flocculent suspensions. The output from the series of bioreactors is flowed continuously or semicontinuously to a liquid-solids separator to partition the mixed liquor bioslurry from the biodegraded waste residue The mixed liquor bioslurry containing small amounts of biodegradation residue is returned to the slurry being processed for recycling. Off-gas components from the system are recirculated back to one or more of the bioreactors, to return high volatility toxic constituents for increased microbial degradation and control of volatile toxic constituent emissions from the process. The related system is also disclosed and claimed.

    摘要： A periodic multistage process which minimizes fugitive pollutant emissions has been developed for the removal and destruction of volatile, semi-volatile, and non-volatile organic contaminants from either water, wastewater, or spent granular activated carbon. This invention relates to methods, materials, and systems for treating these contaminants by a process and devices which uniquely combine granular activated carbon adsorption and desorption with biological treatment. The process and devices extend existing treatment systems by: (1) providing biofilm growth in a Sequencing Batch Biofilm Reactor on gas permeable membrane which uses oxygen for the supply of the electron acceptor and other organics (e.g., methane), as needed, for the supply of alternative electron donors, (2) limiting the flow of gases to that which is needed to meet the demand of the microorganisms only and, thus, minimize the escape of volatile organic contaminants in the carrier gases, (3) bioregenerating granular activated carbon while minimizing the attachment of biomass to the granular activated carbon, and (4) periodically operating the Granular Activated Carbon-Sequencing Batch Biofilm Reactor system to remove and destroy the organic contaminants present in either water, wastewater, or spent granular activated carbon. The system also optimizes the use of nutrient additives and minimizes the production of unwanted waste byproducts while ensuring that all treated waters, regardless of their original level of contamination, meet the highly stringent clean-up levels established by governing regulatory agencies, and producing granular activated carbon that is regenerated.
