摘要： A method and a reactor system for continuous waste water treatment are disclosed. The method involves the steps of continuously flowing an influent into a treatment basin and continuously flowing an effluent out of the treatment basin into a clarifier. The influent is continuously and completely mixed in the treatment basin. In an additional step, oxygen is introduced into the basin for a first predetermined time period. The introduction of oxygen into the basin is then stopped for a second predetermined time period and then the steps of introducing and stopping the oxygen are repeated. The reactor system includes a treatment basin having an inlet for continuously receiving an influent stream, an outlet for continuously discharging an effluent stream, and contains a mixed liquor. At least one mixer completely and homogeneously mixes the mixed liquor. At least one source of oxygen discharges into the mixed liquor and a controller connected to the source of oxygen cycles the source of oxygen on and off In another embodiment the present invention is a reactor system for treating waste water comprising: a treatment basin having an inlet for continuously receiving an influent stream, an outlet for continuously discharging an effluent stream, and containing a mixed liquor; at least one mixer, said at least one mixer completely and homogeneously mixing said mixed liquor; at least one source of oxygen, said at least one source of oxygen discharging oxygen into said mixed liquor; and a controller connected to said at least one source of oxygen, said controller cycling said at least one source of oxygen on and off to provide alternating cycles of aerobic and anoxic conditions in the basin.

摘要： A system and method for treatment of soot-laden waste water is disclosed. The method comprises the steps of separating the soot from the waste water initially in a clarifier. The concentrated soot is then treated with an activated sludge mixture in a digester with a very long average hydraulic retention time to effectively digest the materials found in the concentrated soot. Soot-free waste water is treated via standard aerobic, and anoxic reactor basins and a clarifier with activated sludge recirculation. The system effectively removes soot from soot-laden waste water in a cost effective manner.

摘要： Methods of removing contaminant metals from aqueous waste streams. A preferred method includes providing an aqueous waste stream containing a metal having a valence of at least one, such as zinc, lead, chromium, copper, iron, aluminum, manganese, cadmium, gold, silver, and mixtures of these metals. The waste stream is substantially free of calcium and magnesium. The process also includes forming a substantially insoluble precipitate of said metal by mixing with the waste stream fatty acids; zinc, potassium, and sodium salts of fatty acids; and mixtures of these materials. The metal precipitate is separated from the waste stream and the water that is subject to the removal process remains substantially free of calcium and magnesium throughout the entire process. The methods of the present invention are particularly effective for the removal of trace amounts of zinc from aqueous waste streams from polystyrene processes.
