Embodiment Construction
[0029] The technical solution of the present invention will be described in detail below with reference to the drawings and embodiments.
[0030] In the prior art, the membrane module is fixedly installed and the membrane unit is poorly decontaminated. figure 1 The present invention is shown to provide a membrane bioreactor including a rotating drum membrane module. The membrane bioreactor includes an ultrasonic unit 36, a rotating drum membrane module 1, an aeration unit, and a water collection unit; the aeration unit continuously performs aeration The water delivery hose 30 and the water collection pipe 300 in the water collection unit are conventionally arranged according to the prior art.
[0031] The aeration unit continues to aerate. When the rotating drum membrane assembly 1 needs to be cleaned, the first motor 10 drives the rotating drum membrane assembly 1 to rotate at a preset frequency through the rotating shaft 12, and the ultrasonic unit 36 is energized for ultrasonic...

The invention relates to a rotary drum membrane component which comprises a plurality of membrane units, a lower support disc used for fixing the membrane units, an upper cover arranged above the membrane units, a rotating shaft that passes through the lower support disc and the upper cover and is fixed on the lower support disc and the upper cover, and a first motor connected with the rotating shaft; and the rotating shaft is driven to rotate by the rotation of the first motor. The invention also provided with a membrane bioreactor comprising the rotary drum membrane component and a cleaning method for the membrane bioreactor. When being used for cleaning contamination, the rotary drum membrane component can rotate according to the predetermined frequency, and friction is generated between the membrane units and water, so that the contamination to the membrane units can be more easily reduced; the rotary drum membrane component can be used for stirring sewage, so that the filter work can be more effectively carried out; and furthermore, the vibration action of ultrasonic wave for the membrane units is more uniform, so that the vibration efficiency is improved, and the number of ultrasonic units can be reduced.
Description
Technical field [0001] The present invention relates to the field of biofilm reaction sewage treatment, in particular to a rotating drum membrane module, a membrane bioreactor containing the rotating drum membrane module, and a cleaning method for the membrane bioreactor. Background technique [0002] Membrane bioreactor, referred to as MBR in English, is a new type of sewage treatment technology that combines a membrane separation unit and a biological treatment unit. Compared with the traditional sewage treatment process, this technology has the characteristics of high treatment efficiency, stable effluent quality, compact equipment, small footprint, easy automatic control, simple operation and management, etc. Therefore, this technology is highly valued. At present, the technology has been applied to many industries such as biopharmaceutical, food production, industrial and domestic sewage treatment. [0003] The two main forms of membrane modules currently used are flat membr...
