Problems solved by technology
[0003] Most of the existing full-membrane treatment systems for sewage reuse have poor treatment effects and cannot remove heavy metals in water. The water quality after treatment is relatively hard, and cannot kill harmful bacteria and viruses in sewage, which cannot meet the requirements of sewage reuse. requirements

The invention discloses a full-film treatment system for sewage recycling. The full-film treatment system for sewage recycling comprises a pretreatment pond; a PLC controller is arranged on the surface of the outer side of the pretreatment pond; the input end of the PLC controller is electrically connected with the output end of an external power supply; a filter screen is arranged on the surface of the inner side of the pretreatment pond; the side surface of the pretreatment pond is connected with an aeration tank through a connecting pipe; the side surface of the aeration tank is connected with a membrane bioreactor through a connecting pipe; the lower surface of the membrane bioreactor is connected with a comprehensive treatment pond through a connecting pipe; electromagnetic valves are arranged on the surfaces of the outer sides of the connecting pipe; and a water pump is arranged on the upper surface in the comprehensive treatment pond. The full-film treatment system for sewage recycling improves the sewage treatment effect, can remove most of heavy metals from water and fulfills the aim of softening water quality; the membrane bioreactor can realize deep purification of the sewage; meanwhile, the nitrification effect is remarkable, phosphorus and nitrogen can be removed deeply, the mesh diameter of an ultrafiltration membrane is less than 0.001 mm, and harmful bacteria and part of viruses can be filtered out.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a full-membrane treatment system for sewage reuse. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. Replace the terminal secondary settling tank of traditional biological treatment technology with membrane modules, maintain a high concentration of activated sludge in the bioreactor, increase the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reduce the remaining sewage by maintaining low sludge load amount of mud. [0003] Most of the existing full-membrane treatment systems for sewage reuse have poor treatment effects and cannot remove heavy metals in water. The water quality after treatment is relati...
