Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a transparent shell ultrafiltration membrane. Background Art

[0002] At present, in most domestic projects of advanced wastewater reuse and zero discharge, due to the instability of the raw water from the owner, the uncertainty of the biochemical system, the volatility of the tail-end fine COD removal unit, and the high maintenance cost of the pre-treatment and security processes before the membrane, excessive pollutants are directly introduced into the ultrafiltration system in the two-stage membrane method without being reasonably removed, causing extremely severe and intractable pollution to the ultrafiltration system. Moreover, due to many adverse factors on-site, it is very difficult for operators to accurately judge whether the ultrafiltration system needs chemical cleaning through the analysis of the existing data.

[0003] With the increasing awareness of environmental protection, it is required to reduce the solid waste discharge. The longer the ultrafiltration membrane element is used, the lower the solid waste discharge will be, and the total amount of solid waste discharge will become a restricting factor for operating the water treatment system. For various projects of advanced wastewater reuse and zero discharge, it is imperative to realize the resource utilization of wastewater. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a transparent shell ultrafiltration membrane to clearly understand the pollution degree of the ultrafiltration membrane.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transparent shell ultrafiltration membrane includes a transparent membrane cylinder, membrane filaments, end caps, a water inlet, a water outlet, and a concentrated water outlet and a sludge discharge port are further arranged on the wall of the transparent membrane cylinder. The membrane filaments are arranged inside the transparent membrane cylinder, and a plurality of low-light perspective devices are alternately arranged on the cylinder body of the transparent membrane cylinder. The low-light perspective devices extend into the inside of the transparent membrane cylinder. The low-light perspective device includes a transparent shell, a cesium photocathode is arranged at the front end inside the transparent shell, the cesium photocathode is connected to a near-infrared image intensifier, and the tail end of the transparent shell is embedded in an opening on the wall of the transparent membrane cylinder.

[0007] The low-light perspective device is externally connected to a low-light perspective instrument.

[0008] A plurality of the near-infrared image intensifiers are provided.

[0009] The number of the low-light perspective devices is 3 - 5.

[0010] The near-infrared image intensifier is connected to the opening on the wall of the transparent membrane cylinder through a seal.

[0011] The concentrated water outlet is close to the water outlet.

[0012] The sludge discharge port is close to the water inlet.

[0013] The range of light waves received by the described near-infrared image intensifier tube is 740 - 795 nm.

[0014] Compared with the existing technology, the beneficial effects of the present utility model are as follows:

[0015] 1. A low-light perspective device is added to the ultrafiltration membrane. By connecting it to a low-light perspective instrument, it is possible to finely observe the contaminated area of the membrane filaments, the thickness of the accumulated pollutants, and conduct component analysis of the pollutants.

[0016] 2. Under the same usage conditions, the chemical cleaning cycle of the ultrafiltration membrane of the present utility model is extended by 1.25 times compared to the conventional ultrafiltration membranes in the industry (taking the on-site middle water reuse in the steel industry as an example, the chemical cleaning cycle of the ultrafiltration membrane of the present utility model is 23 - 25 days, and that of the imported ultrafiltration membrane is 18 - 20 days; taking the on-site deep reuse of coking wastewater in the coal chemical industry as an example, the chemical cleaning cycle of the ultrafiltration membrane of the present utility model is 17 - 20 days, and that of the imported ultrafiltration membrane is 12 - 16 days); the timely accuracy rate of chemical cleaning reaches 98.4%, an increase of 27.4%, and the thoroughness rate of chemical cleaning reaches 99.7%, an increase of 12.7%; the average service life reaches 5 - 6 years, which is extended by 1.36 times compared to the conventional ultrafiltration membranes in the industry.

[0017] The transparent membrane tube of the ultrafiltration membrane of the present utility model is visualized and supplemented with a low-light perspective device. It can not only directly visualize the pollutant concentration and the accumulation of pollutants in the existing ultrafiltration system, but also clearly understand the degree of contamination of the membrane filaments through the use of the low-light perspective device. Most importantly, it can achieve refined management and accurate chemical cleaning of the ultrafiltration membrane system. Description of the Drawings
