Problems solved by technology

However, the reason why the membrane bioreactor has not quickly and completely replaced the position of the traditional water treatment technology in the water treatment industry is that there are still some problems in the water treatment technology of the membrane bioreactor, such as: membrane fouling, microbial biological activity Reduce the accumulation of non-degradable substances, low oxygen mass transfer efficiency and difficult disposal of excess sludge, chemical cleaning waste liquid causes secondary pollution, high energy consumption and equipment costs
[0004] It can be concluded that there are three major problems in current research and practice: maintaining a constant high flux; effectively controlling membrane fouling; and reducing the cost and operating costs of membrane bioreactors

Abstract

The invention relates to a membrane material modified membrane bioreactor in the technical field of wastewater treatment. The membrane material modified membrane bioreactor comprises an immersible pump, a reactor and a water storage tank sequentially connected; and the inside of the reactor is provided with a slab membrane. The slab membrane is an organic porous membrane material; and the outer surface of the slab membrane is evenly coated with a nanometer TiO2 layer. The membrane material modified membrane bioreactor utilizes the photocatalytic oxidation function and super-hydrophilicity of nanometer TiO2 to modify the membrane material and achieves the aims of alleviating membrane pollution and stabilizing membrane flux.

Description

technical field [0001] The invention relates to a device in the technical field of sewage treatment, in particular to a membrane bioreactor modified by membrane material. Background technique [0002] In order to adapt to the development of the times, improve the reuse rate of sewage, control water pollution, and alleviate the shortage of water resources, various new and efficient water treatment technologies have been gradually developed. Membrane bioreactor (MBR), as a representative technology of advanced water treatment technology, is an efficient sewage treatment and reuse process, which can be considered as a very effective means to solve the shortage of water resources. [0003] Compared with the traditional water treatment process, the membrane bioreactor water treatment technology shows great advantages. Its main advantages are: good effluent quality, impact load resistance, small amount of sludge production, and long residence time are beneficial to slow-growing pl...
