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. The hollow fiber membrane module is used for braiding application, and the air volume is 1m under the condition of air-water ratio of 20:1 (the general design value is 15-30:1). 3 / hr, temperature 12~29℃, pH 6.5~8.0, stable operation for 6 months, the flux of this hollow fiber membrane module is stable at 10-15L / m 2 ·h, the operating pressure is 16-20kpa. Compared with traditional components, the pollution of the pollution layer is effectively controlled, and there is no generation of broken wires. 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 Miscellane...

Abstract

A braiding technique for reinforcing the root part of hollow fiber membrane module features that the anticorrosion and hydrophobic cord threads or nylon wires are used to be braided at the adhered positions on the top or bottom sides of hollow fiber membrane module to increase its strength. The number of the braided fibers in a bundle is 10-50 and the number of the braided lines is 1-5.

Description

technical field [0001] The invention belongs to the technical field of application of membrane separation technology, and in particular relates to a root braiding technology for local reinforcement of hollow fiber membranes. 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 being 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, the cost performance of membrane materials and the flux attenuation caused by membrane fouling have seriously hindered the promotion and application of membrane te...
