Embodiment Construction

[0024] Embodiments of the present invention: the present invention can build anaerobic pond 1 at the lower end of domestic waste landfill, and then install a UASB2 (upflow type anaerobic sludge bed reactor), UASB2 is a kind of compact anaerobic reactor , then connect a high-efficiency catalytic internal electrolysis reactor 3 behind UASB2, build an integrated clarifier 4, and build an aerobic reaction treatment unit A behind the integrated clarifier 4 2 O pond 5 and sedimentation tank 6, then build an integrated clarifier 7 behind the sedimentation tank 6, the integrated clarifier 7 is finally connected to the integrated membrane treatment equipment 8, and the integrated membrane treatment equipment 8 can adopt domestic CTA-NF (energy-saving Type low desalination reverse osmosis) composite membrane as a nanofiltration membrane module.

[0025] In the integrated clarifier 4, it is divided into a reaction zone 9, a second reaction zone 10, a sludge back-mixing zone 11, a sedimen...

Abstract

The invention discloses a process for disposing refuse percolate by using diatomaceous soil and UASB as the core which consists of, collecting the refuse percolate into an anaerobic pond for preliminary precipitation and anaerobic reaction, loading into UASB for anaerobic treatment, entering the inner electrolytic reactor for iron chips inner electrolytic treatment, flocculating and precipitating the contaminants in the water by the diatomaceous soil in the incorporated clarification tank, loading the percolate into A20 pond and sedimentation tank for aerobic reaction and deposition, then loading again into incorporated clarification tank, charging diatomaceous soil, finally loading the percolate into an incorporated membrane treating plant for membrane process treatment.

Description

Technical field: [0001] The invention relates to a method and device for treating landfill leachate with diatomite and UASB as the core, and belongs to the technical field of sewage treatment. Background technique: [0002] The treatment of landfill leachate has always been a major issue in urban environmental governance. The quality of landfill leachate treatment is closely related to the citizens of the entire city. However, domestic sewage has a wide range of sources and many pollutants, and it is costly and difficult to treat. Especially the landfill leachate from various industries in cities has complex components, many pollutants, and a large amount of toxic and harmful substances, which are difficult to treat. The existing sewage treatment methods can be summarized into two categories: physical chemical method and biochemical method. [0003] Physical and chemical method: The most widely used physical and chemical method is flocculation. Its advantages are small inve...
