    摘要: A fluidized bed biological filtration assembly for use with fish tanks and the assembly has a vertically oriented tubular housing with an elongated upper inner tubular member centrally positioned therein. A top cap covers the top end of the tubular housing and it has a contaminated water inlet port and a filtered water port. The inlet port is in communication with the top end of the inner tubular member and the outlet port is in communication with the filtering chamber formed by the interior of the tubular housing. An inverted cone shaped bottom cap is secured to the bottom end of the tubular housing and its interior has a lower inner tubular member extending upwardly and connected to the bottom of the upper inner tubular member. A plurality of radially extending horizontal slots in the bottom end of the lower inner tubular member allow contaminated water to exit therefrom and pass upwardly through filtering particulate in the bottom of the housing. The flow of the water upwardly through the particulate material produces a fluidized pattern that maximizes filtration.

    摘要: A filtering process for and apparatus separating air bubbles and granular filter medium from a filtrate contaminated by the filter medium and bubbles when passing through a filter bed formed by the filter medium for treatment of a suspension or liquid solution, a gas being passed through the filter medium in contact therewith, includes providing a treated filtrate zone (3) above the filter bed (2), collecting the treated filtrate in the filtrate zone, conducting granular filter medium from the filter bed (2) upwardly through a conveying pipe (4) to a position above the filter bed and thereafter downwardly through a washing apparatus (5) from which the filter medium is precipitated onto a plate (11) above the filter bed. Treated filtrate flows through a separate chamber formed by a cylinder (12) around the washing apparatus (5) and then upwardly through the lower end of the washing apparatus and outwardly through the upper end of the washing apparatus and thereafter leaves the system through an overflow outlet pipe (7). The filtrate leaves the system through a separate filtrate outlet (8). The filtrate flowing downwardly through the separate chamber functions as the washing liquid and flows at a rate sufficiently low for separation of gas bubbles in the chamber therefrom. The filtrate washing liquid flowing upwardly through the washing apparatus (5) flows at a rate sufficiently low for separating the downwardly conducted granular filter medium.

    摘要: The invention is directed to a sewage treatment system and method for treating sewage by microbes. The system includes and the method uses a settling tank with residual activated sludge and mixed liquor and an activated biofilm filter. Incoming sewage into the settling tank forms a settling tank liquor mixed liquor. Increments of the settling tank liquor mixed liquor are treated in the activated biofilm filter and returned to the settling tank where the treated mixed liquor improves the quality of the settling tank liquor mixed liquor in the settling tank. The process of treating and returning incremental quantities of the settling tank liquor mixed liquor continues over a Predetermined period of time after which the sewage is fully treated.

    摘要: A process and a device for biologically treating an organic waste mixture containing organically polluted waste water and solid components. The process and the device involve exposing the organic waste mixture to a first decomposition stage where the solid components and the waste water are separated from one another and where the solid components are decomposed under predominantly aerobic conditions. The waste water is then passed to a second decomposition stage where the waste water is decomposed under anoxic conditions. Thereafter, the waste water is passed to a third decomposition stage where the waste water is decomposed again under aerobic conditions thereby creating recirculation water. At least a portion of the recirculation water is returned from the third decomposition stage to the first decomposition stage for continuously recirculating water through and between respective decomposition stages.

    摘要: A method of preparing and cleaning a floating filter medium for a biological cleaning apparatus includes the steps of forming a filter layer by placing in a treating tank a granular floating filter medium having a specific gravity of about 0.3 or less and a particle size of 1 to 15 mm. Wastewater enters the tank and flows through the filter layer. Excess sludge is separated and removed from the filter medium by discharging an amount of water from the treating tank, from below the filtered layer, equivalent to 0.5 to 1.5 times the filling amount of the filter medium in a time period of between 5 to 90 seconds.

    摘要: To purify untreated water, for example waste water, containing organic pollution, materials in suspension and nitrogen-containing pollution, reagents are added under conditions adapted to coagulate all of the materials in suspension, including colloidal materials, to form granular physical/chemical floc. Diluting water is added, preferably after the reagents, in a flowrate ratio of at least 2/1. The dilute flocculated water is caused to flow through a bed of sludge in the form of such dense and granular floc and denitrifying bacteria. The bed is subject to turbulent but intermittent agitation. A denitrified effluent is recovered. This denitrified effluent is caused to flow through a biological filter or preferably through a fluidized bed containing nitrifying bacteria and into which oxygen or air is injected. A clarified effluent is obtained, some of which is recycled as the diluting water.
