Abstract

This invention describes an innovative biomembrane water-filtration system, comprising a biological filtration bed section and a membrane separation section. The biological filtration bed section, operated either in the fixed bed mode or in the moving bed mode, has such two functions as biological treatment and quick filtration, and has such advantages as high load, high efficiency, high stability and simplicity for operation. The membrane separation section uses membrane filtration modules to remove the particles in the effluent water from the biological filtration bed section, thus producing high quality clarified water.

Description

technical field [0001] The present invention relates to an innovative biofilm water filtration treatment system, which is composed of a "biological filter bed area" and a "membrane separation area". Background technique [0002] Membrane bioreactor technology (membrane bioreactor, MBR) is usually used in secondary biological treatment to remove COD, suspended solids (SS) and nitrogenous pollutants. Due to the characteristics of biological treatment and membrane filtration, the treated water quality can reach the effect of tertiary treatment, so it is also suitable as a pre-treatment unit for wastewater reuse. The currently developed MBR technology is mainly of the solid-liquid separation type, which usually uses ultrafiltration (UF) or microfiltration (MF) membranes to separate and concentrate biological sludge to obtain good effluent water quality. [0003] Due to the water flux of the membrane module (flux, unit m 3 / m 2 .day) is one of the most important control parame...
