Problems solved by technology

The membrane elements of flat membrane bioreactors on the market are mainly organic membranes. Due to the strength of the membrane material itself, it is necessary to control the transmembrane pressure difference. For PVDF membrane materials, the maximum transmembrane pressure difference is generally not more than 20kPa, which limits the height of a single membrane element

Abstract

The invention relates to a novel superposed immersion type flat membrane element. The element comprises an upper part middle support board (1), a lower part middle support board (2), a middle installation and connecting strip (7), two side edge pressing strips (8), an upper end piece (9) and a lower end piece (10), wherein the two boards, namely the upper part middle support board (1) and the lower part middle support board (2) are provided with a plurality of vertical diversion channels (3), the upper and lower ends of each board are provided with a plurality of water-collecting grooves (6); the two boards are provided with diaphragms (4, 5) respectively; and the cross section of the middle installation and connecting strip (7) is H-shaped, and the upper and lower middle support board (1,2) are separately connected and assembled with the H-shaped middle installation and connecting strip (7). The assembled immersion type flat membrane module has two independent membrane filtration systems of which pumping pressures can be set to be different, thus the normal operation of the immersion type flat membrane module can be ensured; and the immersion type flat membrane module is suitable for the large and medium sewage treatment projects.

Description

technical field [0001] The invention relates to the technical field of sewage treatment. Specifically, the present invention is a biological reaction sewage treatment equipment combined with activated sludge method and biofilm, and is also a new type of membrane bioreactor submerged flat membrane element. Background technique [0002] In recent years, membrane bioreactors have been developed rapidly at home and abroad, and have been popularized and applied as a new type of efficient sewage treatment equipment. Membrane bioreactor has the characteristics of high pollutant removal efficiency, good effluent quality after treatment, and can be directly reused; at the same time, it also has the characteristics of high microbial concentration in the reactor, large processing volume load of the device, and small footprint. It is especially suitable for In the field of small and medium-sized sewage treatment plants and decentralized sewage treatment. At the same time, with the con...
