摘要： The present disclosure provides methods and systems for processing or treating wastewater. The methods of systems of the present disclosure may perform a treatment process on a wastewater stream including gray water and black water to produce a product stream. The product stream may comprise a potable water stream or a stream of treated water with a reduced concentration of one or more contaminant originally included in the wastewater stream.

摘要： Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

摘要： Disclosed is a chemical wastewater treatment and reuse system, which corresponds to a raw water tank and includes a regulation tank pretreatment system, an A/A/O biological treatment system, an MBR treatment system and an electrical control system. The regulation tank pretreatment system includes a grating tank, a primary sedimentation tank and a regulation tank that sequentially communicate with the raw water tank. The A/A/O biological treatment system includes an anaerobic tank group and an aerobic tank group that sequentially communicate with the regulation tank. The MBR treatment system includes a separation tank and a membrane tank that sequentially communicate with the aerobic tank group, the membrane tank communicates with a clarification tank, and the membrane tank and the clarification tank jointly communicate with the sedimentation tank. The sedimentation tank sequentially communicates with a clear water tank, a discharge tank, an advanced treatment tank and a reused water tank.

摘要： An integrated device and method for treating toxic and refractory wastewater are provided. The integrated device includes an adjusting pool, a first-stage reactor, a second-stage reactor, a third-stage reactor, a coagulation sedimentation pool, and a biochemical reaction pool that are sequentially connected in series, and further includes an aeration blower. Each of the first-stage reactor and the third-stage reactor is an advanced oxidation reactor, and the second-stage reactor is a Fenton reactor. The coagulation sedimentation pool includes 2 to 4 stages, and each stage of the coagulation sedimentation pool includes a coagulation tank, a primary sedimentation tank, and a secondary sedimentation tank that are connected in series. The biochemical reaction pool includes an anoxic tank, an aerobic tank, a settling tank, and a clean water tank that are connected in series. The wastewater treatment method combines the integrated device for treating toxic and refractory wastewater with reasonable process parameters.
