Container type electro-Fenton biochemical pool MBR membrane combined water treatment system

Abstract

The invention relates to a container type electro-Fenton biochemical pool MBR membrane combined water treatment system. The system comprises a reaction pool body, a dosing device, a backwashing device, a sludge discharge pump, a PLC control cabinet and a container body; the reaction tank body, the dosing device, the backwashing device, the sludge discharge pump and the PLC control cabinet are all arranged in the container body. The system has the beneficial effects that the whole set of treatment equipment and control equipment are reasonably installed in the reinforced container, batch production is facilitated, and the system has the advantages of being short in construction period, simple and compact in structure and convenient to move; the electro-Fenton oxidation pool is arranged so that the Fenton reagent does not need to be manually added; the anoxic tank and the aerobic tank are arranged, so that the removal efficiency and the removal load of the system on organic matters are improved; the MBR membrane tank is arranged, suspended solids are completely removed so as to improve the effluent quality, free bacteria and macromolecular organic matters which cannot be intercepted by a secondary sedimentation tank in a traditional method are completely isolated in the biological tank under the action of membrane separation, and the suspended solids are effectively filtered while the water yield is ensured.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a container-type electric Fenton biochemical pool MBR membrane water treatment system. Background technique [0002] With the acceleration of the country's urbanization process, the quality of urban domestic sewage and industrial wastewater is getting worse, especially the main pollution indicators such as organic matter and ammonia nitrogen continue to rise, which brings great pressure to the treatment of wastewater. The organic matter in the water body is mainly caused by the discharge of urban domestic sewage and industrial waste water such as food and paper making. Organic pollutants often undergo anaerobic reactions and produce various reducing gases. These gases make it difficult for animals and plants in the water to survive and produce foul odors. Ecological environment of polluted water bodies. The main sources of ammonia nitrogen in water bodies inc...

Problems solved by technology

In the actual production situation, it is often necessary to reduce the organic matter and ammonia nitrogen content in the water body at the same time, so the biological engineering method is often used for water treatment, such as A 2 O process mainly includes anaerobic section, anoxic section, aerobic section and sedimentation tank. Although this process is widely used, there are still significant deficiencies, such as conflicting sludge ages of various strains, interference of dissolved oxygen in circulating water, and pollution. Problems such as mud swelling and floating directly lead to long waste water treatment cycle and unsatisfactory effect. In addition, the large amount of construction during the construction process occupies a large area, which further limits the wide application
