摘要： A self-adjusting fluid surface skimmer and a wastewater treatment system incorporating the same are provided. In one embodiment, the skimmer includes an intake passage and an outlet passage. The intake passage comprises first and second passageways connected by a flexible coupling. A collar is positioned around the first passageway near an intake opening. At least one buoyant member is attached to the collar and facilitates self-adjustment of the skimmer. A gas inlet is disposed in the outlet passage and allows for the movement of gas through the outlet passage, which creates a suction effect in the intake passage. The wastewater treatment system comprises an aeration tank disposed in a settling tank such that a clearance is created between the two tanks. A skimmer according to the present invention is disposed within the clearance. The skimmer enables further removal of solids from treated fluid within the settling tank prior to leaving the treatment system.

摘要： A wastewater treatment process that provides improved reduction of total solids through endogenous respiration while reducing biochemical oxygen demand and utilizing biological nutrient reduction. The wastewater treatment process uses an efficient aeration delivery system to drastically reduce the time needed to oxidize organic matter, and recirculates, shreds and homogenizes the organic matter and microorganisms and oxygenates the entire mass many more times than traditional systems resulting in a greater biological solids digestion rate.

摘要： The invention is a biological process for purifying waste water in order to produce an effluent with a low content of carbon and of oxygenated nitrogen compounds. The process includes an initial step of mixing the waste water in a biological reactor with activated sludge to denitrify the resulting mixture. Then, air is introduced into the mixture to form an anoxic sludge thereby directly oxidizing carbon present in the anoxic sludge and removing carbon therefrom, simultaneous with the denitrification. The anoxic sludge is clarified to separate it from a denitrified intermediate effluent. The clarified anoxic sludge is recycled to the biological reactor. Then, intermediate effluent is nitrified to form a nitrified liquor and a portion of the nitrified liquor is recycled into the anoxic sludge that is present in the biological reactor, thereby subjecting the anoxic sludge to oxygen present in nitrified compounds and consequently further removing carbon from the anoxic sludge, simultaneous with the denitrification. The rate of removal of carbon is controlled as a function of the flow rate/pollution characteristics of the anoxic sludge while a redox potential of the anoxic sludge is continuously measured. A nitrate concentration of the intermediate effluent is continuously measured. There is an adjustment of an amount of air introduced into the anoxic sludge in accordance with the measured redox potential and measured nitrate concentration. A recycling flow rate of the nitrified liquor is adjusted in accordance with the measured redox potential and measured nitrate concentration. The remaining nitrified liquor is the final effluent.

摘要： There is provided a process for treating industrial wastewater that substantially eliminates the generation of excess solids in the system requiring mechanical removal. The wastewater undergoes an equalization step wherein hydraulic flow is smoothed and the pH of the wastewater is adjusted to near neutral pH conditions. The equalized wastewater is then transferred to aeration tanks where the organic process wastes are absorbed, metabolized, or otherwise biodegraded by the microorganisms in the mixed liquor in the aeration tanks. After the aeration step, the wastewater is separated by gravity in a clarifying step to separate the wastewater into a liquid phase and a semi-solid phase. The clarified liquid phase is withdrawn from the clarifier and discharged, while the semi-solid phase is transferred either directly back to the aeration/biological treatment step, as recycle-activated sludge, or into a bioreactor as waste-activated sludge. In the bioreactor the semi-solid phase is subjected to active aeration. The aerated waste-activated sludge is then batch-recycled to the equalization tank discharging to the aeration step where it is mixed into newly introduced untreated wastewater and undergoes a new cycle of biological treatment. As a result of the indirect batch-recycling of bioreactor waste-activated sludge into the mixed liquor (biomass containing waste sludge) under aeration, which is also receiving recycle-activated sludge and enzymes, the excess solids generated in this process virtually eliminated.

摘要： A improved activated sludge system and method for treating wastewater containing contaminants is disclosed which offers a broad array of advantages over conventional activated sludge wastewater treatment systems, including smaller size, higher rates of operation, higher oxygen transfer efficiency, lower operating costs, and a substantially decreased level of excess sludge production. The improved activated sludge waste treatment system of the present invention has two processing tanks rather than the several tanks that are commonly found in activated sludge systems for treatment and sludge management equalizations, including anaerobic processes. The first processing tank is a contact tank which hosts a reaction which functions not merely to digest the maximum amount of contaminants, but instead to bind contaminants to the microorganisms through absorption, adsorption, precipitation, or digestion so that they can then be removed from the liquid in a solid/liquid separator. The activated sludge removed by the solid/liquid separator is then supplied to a digester tank containing a high concentration of activated sludge, where virtually complete digestion is achieved to minimize the volume of solids remaining. Activated sludge is provided from the digester tank to the contact tank to facilitate the reaction in the contact tank.
