Abstract

The invention discloses a seaborne platform high-salinity domestic sewage processing and recycling device.The device mainly comprises an inclined oxidation ditch and a segmented MBR pond.The inclined oxidation ditch mainly comprises a first aerobiotic pond, an anaerobic pond, an anoxic pond, a second aerobiotic pond, a secondary sedimentation pond and a middle water pond.The first aerobiotic pond, the anaerobic pond, the anoxic pond, the second aerobiotic pond, the secondary sedimentation pond and the middle water pond are constructed together to form the inclined oxidation ditch.The segmented MBR pond mainly comprises a biochemical pond, membrane pond, a vacuum meter and a suction pump which are sequentially connected in series.The biochemical pond and the membrane pond are constructed together to form the segmented MBR pond.The vacuum meter and the suction pump are installed outside the membrane pond and matched with a membrane assembly to achieve intermittent drainage.Detachable supporting columns are arranged at the bottom of the inclined oxidation ditch.Foot brake movable wheels are arranged at the bottom of the segmented MBR pond.According to the seaborne platform high-salinity domestic sewage processing and recycling device, the integrated design is adopted, the floor area is small, the device can be disassembled into two parts to be operated independently, and seaborne platform high-salinity domestic sewage processing and recycling device is particularly suitable for dispersed domestic sewage treatment.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a treatment and reuse device for high-salt domestic sewage on an offshore platform. Background technique [0002] The pollution of water resources is deteriorating day by day, and the characteristics of water quality are complex and changeable. In order to solve point source and non-point source pollution, it has become the theme of water environmental protection, especially for scattered and difficult to collect small water pollution sources, which urgently need mobile treatment devices to treat them. deal with. Among the biological treatment technologies, the activated sludge method and its derived technologies occupy an indispensable and important position. Among these biological treatment technologies, MBR and oxidation ditch are currently one of the most important treatment processes for wastewater biological treatment. [0003] Oxidation ditch process is an activate...
