Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing.
[0020] Such as figure 1 As shown, the detection device 20 for flat filter membrane elements according to the present invention includes a simulated fluid box 21 . The simulated fluid tank 21 is used to accommodate the liquid to be tested, such as polluted water. In order to ensure the continuous and stable operation of the detection device 20 , an aeration device 22 is provided in the simulated fluid tank 21 . The aeration device 22 can make the waste liquid in the simulated fluid tank 21 uniform, and strengthen the contact between the microorganisms in the simulated fluid tank 21 and the dissolved oxygen, thereby ensuring that the microorganisms in the simulated fluid tank 21 can eliminate the organic matter in the sewage under the condition of sufficient dissolved oxygen. decomposition. Wherein, a plurality of flat filter membrane elements 3 are accommodated inside the...

The invention provides a device for detecting a flat filtering membrane element. The device comprises a simulated fluid box, a circulating device and a metering piece, wherein the simulated fluid box is used for containing the flat filtering membrane element; the circulating device can circulate fluid between the flat filtering membrane element and the simulated fluid box under fixed pressure; the metering piece is used for detecting the flow of the fluid circulated by the circulating device. According to the device for detecting the flat filtering membrane element according to the invention, the water flux and pollution resistance of the flat filtering membrane element can be effectively detected, so that the quality of the flat filtering membrane element is ensured.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a detection device for flat filter membrane elements. Background technique [0002] In recent years, water pollution is one of the main factors restricting the normal development of society in various countries. Sewage discharge has attracted more and more attention from governments and people in various countries. my country is one of the countries with serious water pollution. In order to solve the problem of water pollution, the sewage and wastewater discharge standards are constantly improving. [0003] Membrane bioreactor (MBR) can be called the "best available technology" for sewage treatment and recycling, and has been widely used in water treatment such as industrial sewage, construction sewage, domestic sewage, urban sewage and garbage permeate treatment engineering field. Although many types of filter membranes can be used in membrane bioreactors, flat MBR membrane...
