摘要： A method of and an apparatus for rejuvenating a wastewater treatment system of the type including a septic tank, an aerobic treatment unit or the like connected by a pipe to a plugged downstream soil absorption system includes a wastewater treatment unit which is interposed between the septic unit/aerobic treatment unit and the downstream soil absorption system. The wastewater treatment unit includes a single piece or a multiple piece solids settling and retention basin within which is suspendingly supported a wastewater treatment mechanism essentially of the type disclosed in U.S. Pat. No. 5,264,120. The wastewater treatment mechanism includes filters for filtering and settling solids from wastewater and flow equalization ports for effecting flow equalization thereby eliminating flow surges to the downstream plugged soil absorption system. By utilizing an extremely compact solids settling and retention basin and its attendant operative components, solids are prevented from passing beyond the wastewater treatment unit to the failed soil absorption system. In this fashion the wastewater treatment unit of the present invention can rejuvenate wastewater treatment systems which have failed, and if installed prior to such failure, can extend the life thereof substantially indefinitely. The latter and other advantages are achieved at relatively low cost, absent destruction of existing sod or lawn, moving fencing, trees, etc., and absent creating a hazard for individuals, particularly small children.

摘要： A wastewater treatment tank with influent gates (24) and pre-react zone with an outwardly flared lower portion. Influent passes over influent gates (24), which introduce turbulence, causing aeration, and reducing flow velocity. As influent flows out of the influent gate housing (20), flow velocity is further reduced by contact with the surface of the wastewater in the basin and influent flow is directed laterally by an influent gate bottom (30). A pre-react zone director (34) spaced apart from the bottom (42) of the basin encloses the influent gate housing (20) and utilizes an outwardly flared lower portion, or flap (38), to further reduce flow velocity and enhance laminar flow. This results in minimal disturbance of settled sludge blanket, allowing it to act as a natural biological filter, which in turn results in a superior supernatant.

摘要： A water treatment system, method and apparatus for removing sediment, chemical pollutants and debris from contaminated stormwater runoff using physical, chemical and biological processes by passing runoff water preferably through a two-stage filtering and treatment system. The apparatus includes a first stage chamber filter system comprising a water storage area, a mulch layer, a soil mixture of aggregate, organic material, soil, and live woody and/or herbaceous plants. The second stage treatment system is a water-filled lower chamber with baffles to increase the flow path of treated runoff through the chamber. Contaminated stormwater runoff or wastewater effluent is directed to and passes through the first stage chamber by gravity where the contaminated water is filtered and treated by the mulch, soil and plant filter media under aerobic conditions. The treated water from the first stage is directed to the second stage water-filled chamber where it is further treated through physical means (sedimentation) and anaerobic biological processes and discharged to the receiving waters or drainage system. The first stage chamber can be used without the second stage chamber when conditions warrant.

摘要： Novel methods for biodegrading nitroaromatic compounds present as contaminants in soil or water using microorganisms are disclosed. Water is treatable directly; dry soil is first converted into a fluid medium by addition of water. The preferred method comprises two stages, each employing microorganisms: a fermentative stage, followed by an anaerobic stage. The fermentative stage is rapid, wherein an inoculum of aerobic and/or facultative microorganisms ferments a carbohydrate added to the fluid medium, exhausting the oxygen in the fluid medium and thereby inhibiting oxidative polymerization of amino by-products of the nitroaromatics. In the subsequent anaerobic stage, an inoculum of a mixed population of anaerobic microorganisms completes the mineralization of the contaminant nitroaromatics, using the remaining carbohydrate as a carbon and energy source. Preferably, the carbohydrate is a starch and the aerobic and/or facultative microorganisms are amylolytic, which cleave the starch at a moderate rate throughout both stages, ensuring a sustained supply of metabolizable carbohydrate. The microorganisms are preferably selected to be resistant to the types and concentrations of nitroaromatics present as contaminants.

摘要： In a water treating apparatus the water is passed over a plurality of stages to a lower plane, each stage having a water trough, a section for the free fall of the water, and a catch. This makes possible the intensive mixing of the water with components of the air, especially oxygen and amino acids, as well as the action of natural light radiation onto the water.
