In the prior art, the water outlet of the membrane element of the flat membrane MBR is set on the top of the membrane element, the water flow channel through the filter membrane is long and narrow, and the pressure head loss is serious; and the installation method of the single-layer membrane module makes the aeration unable to fully play its role. Waste of drive energy for vacuum pumps
[0006] In addition, membrane fouling is an inevitable phenomenon in the membrane filtration process. Membrane fouling leads to a decrease in the water flux of the membrane. The membrane must be cleaned to maintain the normal use of the membrane.
In the prior art, physical methods are used to clean the membrane, but the efficiency is low because it cannot be done online

The invention relates to a multi-channel double-layer type flat membrane combined apparatus, which comprises a first membrane box and a second membrane box, wherein the first membrane box is arranged on the upper side of the second membrane box, the lower side of the second membrane box is provided with an aeration box, the aeration box comprises an aeration pipeline, at least two double-water outlet membrane elements are respectively filled in the first membrane box and the second membrane box, any one double-water outlet membrane element comprises two water outlets, each water outlet is connected with a water collecting pipe, and one ends of the water collecting pipes respectively extend onto the outer sides of the first membrane box and the second membrane box. According to the present invention, the filling density of the flat membrane combined apparatus is increased, the occupation area is reduced, the aeration utilization rate is substantially increased, the water collecting process is shortened with the double-water outlet membrane element, the suction energy consumption of the filtered water is reduced, the online membrane washing is easily achieved, and the online washing efficiency is increased.
Description
Technical field: [0001] The invention relates to the field of physics, in particular to sewage treatment technology, in particular to a multi-channel double-layer flat membrane module. Background technique: [0002] Membrane bioreactor (MBR) is a new type of sewage treatment device that combines high-efficiency membrane separation technology with activated sludge method. Among them, the membrane module is directly immersed in the liquid mixture of activated sludge, and there is no need to set up a special secondary settling tank or a special filtration system, which reduces the floor space and can be used for industrial and municipal treatment. sewage. [0003] Compared with the hollow fiber membrane bioreactor, the flat membrane bioreactor has higher pollution resistance, and can still maintain high flux under high sludge concentration (flux is the water production of the membrane), so the sewage treatment efficiency is higher. The impact resistance is stronger, and the w...
