Embodiment Construction

[0014] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention provides a kind of biofilm unit that can be put into the sewage pond to be treated. The biofilm unit includes a support plate 10, a film cloth 20 suitable for the size of the support plate 10, and fixes the two sides of the support plate 10 by hot-melt welding respectively. On the welding pattern, a film cloth 20 is fixed on the front side of the support plate 10 , and a film cloth 20 is fixed on the back side of the support plate 10 . The water outlet 17 of the support plate 10 is connected to the water pump to pump water. Under the action of the water pump, a negative pressure is formed inside the biofilm unit, and the sewage penetrates from the outside of the biofilm unit to the inside under the action of the negative pressure; under the separation of the membrane cl...

Abstract

The invention provides a biomembrane unit. The biomembrane unit comprises a support board provided with a plurality of raised strips and membrane cloths fastened to the support board, a water chute is formed between adjacent raised strips, and each of the raised strips is provided with through holes connecting two surfaces of the support board. The invention also provides a membrane bioreactor comprising the biomembrane unit. Each of the raised strips is provided with through holes for the mutual flow of clear water on two surfaces of the support board, so when clear water penetrating one of the membrane cloths is more than clear water penetrating the other one of the membrane cloths, the clear water penetrating the one of the membrane cloths can enter the water chute on the other surface because of a water pressure difference, and the water chute on the other surface is fully utilized to make the water smoothly and uniformly flow and the water output stable.

Description

technical field [0001] The invention relates to membrane bioreactor technology, in particular to a novel flat-plate biofilm unit suitable for sewage biochemical treatment. The present invention also provides a membrane bioreactor comprising the above biofilm unit. Background technique [0002] Membrane bioreactor (MBR) is a new type of high-efficiency sewage treatment device that combines membrane separation technology with traditional activated sludge process. Compared with the traditional activated sludge method, the membrane bioreactor uses membrane separation to replace the sedimentation and separation of the secondary settling tank in the traditional activated sludge method, which greatly increases the concentration of activated sludge in the system, so that the effluent water quality and volume load of the system are improved. Greatly improved, the effluent can be reused as reclaimed water, or directly enter the downstream RO / NF desalination system to produce pure wat...
