Embodiment Construction

[0006] Will contain COD 200~500mg / L, BOD 5 100~300mg / L, ammonia nitrogen 50~160mg / L, SS 20~50mg / L domestic sewage enters the activated sludge membrane bioreactor for treatment. 0.4m 3 / hr, temperature 12~29℃, pH 6.5~8.0, stable operation for 6 months. The flat membrane flux in the new membrane module is stable at 25-40L / m 2 h, the operating pressure is 18-22kpa, and the treatment effect is stable. The COD value of the system effluent varies between 10 and 30mg / L, and is generally stable below 20mg / L. 5 The value fluctuates between 1 and 3mg / L, the ammonia nitrogen is stable below 10mg / L, the SS is stable below 0.3mg / L, and the effluent water quality meets the "Urban Sewage Recycling-Urban Miscellaneous Water Quality" (GB / T18920-2002) standard .

Abstract

The invention relates to a new type flat film component that is made up of sheet frame film component, and sheet frame mechanism cleaning brush. The sheet frame film is made up of pressing film, raw net supporting material, supporting board, raw new supporting material, film. And the mechanism cleaning brush is made up of brushing and brush frame. The feature is that it enhances the mechanism cleaning brush to realize the removal of the main pollution of flat film and keeps the advantage of traditional flat film component. The component installs mechanism cleaning brush in the interval clearance between the traditional flat film component to realize online washing, and enhances the yield and useful life of the film component.

Description

technical field [0001] The invention belongs to the technical field of research and development and application of membrane separation technology, and in particular relates to a novel flat membrane module. Background technique [0002] Membrane bioreactor is a technology that combines membrane separation technology and biological sewage treatment technology to treat sewage. Compared with traditional biological sewage treatment technology, it has a small footprint, centralized equipment, modularization, and upgradeability. Advantages such as potential are increasingly valued worldwide [Tom Stephenson, Simon Judd, Bruce Jefferson, Keith Brindle, Membrane Bioreaators for wastewater Treatment], and are considered to be one of the most promising sewage treatment and reuse technologies. However, problems such as high membrane price and flux attenuation caused by membrane fouling have seriously hindered the popularization and application of membrane technology. [0003] Flat membr...
