摘要： Disclosed herein are methods and systems for treating greywater from a microbial food decomposition process. A method includes flowing, into a mixing chamber of a water treatment tank, a first volume of untreated greywater. A second volume of recirculated greywater mixed with ozone gas is flowed into the mixing chamber, and mixes with the first volume of untreated greywater to produce a third volume. The third volume of greywater is flowed into a storage tank. The method further includes diverting a first portion of the third volume out of the water treatment tank, and diverting a second portion of the third volume into a recirculation line that flows the second portion back to the mixing chamber.

摘要： A wastewater treatment apparatus performs both initial rainwater overflow treatment and primary treatment. A wastewater treatment method according to the apparatus, the apparatus modifying an existing primary depositing reservoir to an up-flow high-speed filtration facility, the apparatus using a floating filter and biological filter paper applied to an existing depositing reservoir to perform an initial rainwater treatment. The apparatus can be applied to an existing wastewater treatment facility to eliminate the necessity of installing an additional facility for an initial rainwater treatment facility. The apparatus is further capable of adjusting the flow rate into a biological treatment facility to achieve a target water quality. The apparatus comprises: an up-flow high-speed filtration facility for filtering floating matter contained in wastewater using a floating filter; a sludge holding tank; a biological treatment facility for removing dissolved organic matter contained in the water discharged from the up-flow high-speed filtration facility; and a concentrator.

摘要： A process in which a waste stream containing microbes and organic constituents is passed through a process environment comprising a solid media, microbes, and higher animals, such that some of the microbes and/or organic constituents within the waste stream are removed from the waste stream and some of the removed microbes are destroyed or consumed by the higher animals. The process environment may include an irrigated environment, a submerged environment, or a combined environment.

摘要： Provided is a biological treatment method and an apparatus that allow organic wastewater from a manufacturing process of electronic devices to be neutralized efficiently during its biological treatment with a less neutralizer in contrast to excessive use thereof in the conventional biological treatment and thereby make it possible to reduce an amount of an inorganic coagulant used in the downstream coagulation step and to reduce salt loads in RO membrane separation and ion exchange treatment. Wastewater from a process of manufacturing electronic devices is passed sequentially through two or more biological treatment tanks that include at least two aerobic biological treatment tanks including the final-stage aerobic biological treatment tank while adding a neutralizer to the biological treatment tank or tanks except the final-stage biological treatment tank so that an M-alkalinity of the liquid in the final-stage biological treatment tank is maintained at not more than 50 mg/L as CaCO3.

摘要： Wastewater settlement and purification are described. These descriptions include purification of organically contaminated wastewater in aerobically maintained processes and anaerobically maintained processes. The wastewater may flow from aerobic processing zones to anaerobic processing zones to subsequent anaerobic or aerobic processing zones. Anaerobic processing may be promoted by accumulating the wastewater above a barrier and then flowing the wastewater below a curtain and then back up and over edges of the barrier for subsequent purification, discharge, environmental recharge and/or reuse.
