Embodiment 1

[0029] Such as figure 1 , 2 As shown, an ultrafiltration membrane assembly includes a shell 1 and a filter element made of PP material. Among them, the shell 1 is cylindrical, and the shell 1 is composed of an upper end cover 5 and a lower body 6, the top of the end cover 5 is provided with a concentrated water outlet 7, and the side of the end cover 5 is provided with a water production port 8; the body 6 A water inlet 2 is provided on the bottom side wall.

[0030] The filter element is composed of a membrane cover 3 and a membrane filament 4 . The membrane filament 4 is a polyvinylidene fluoride (PVDF) hollow fiber membrane, the diameter of the membrane filament 4 is 1.25-1.35 mm, and the diameter of the membrane hole is 0.03-0.1 μm; the membrane filament 4 is bent to form a "U" shape, and the membrane is sealed 3. It consists of a ring-shaped PP shell and a glue-sealed injection core. The two ends of each membrane wire are sealed in the ring-shaped shell with epoxy resi...

Abstract

The invention discloses an ultrafiltration membrane module and a method for treating high-turbidity water by using the same. The ultrafiltration membrane module comprises a shell and a filter element, wherein the filter element is composed of a membrane filament and a membrane seal cover; the membrane seal cover divides the inner cavity of the shell into upper and lower parts, namely a water production cavity and a filtering cavity, the membrane filament is located in the filtering cavity, and the two ends of the membrane filament are fixed on the membrane seal cover, and communicated with the water production cavity; the shell is provided with a water production opening which is communicated with the water production cavity, and a water inlet and a concentrated water outlet which are communicated with the filtering cavity; and the concentrated water outlet is formed in the top of the shell, and communicated with the filtering cavity by a central tube passing through the membrane seal cover, and the water inlet is formed in the bottom of the shell. The ultrafiltration membrane module disclosed by the invention is easily disassembled and strong in staining resistance, and sewage blocking is not easily caused.

Description

technical field [0001] The invention relates to the technical field of emergency water treatment, in particular to an ultrafiltration membrane module and a method for treating high turbidity water. Background technique [0002] High turbidity water is a common type of river pollution. The total sediment discharge of the Yangtze River and the Yellow River ranks first among the 13 major rivers in the world. In recent years, natural disasters such as earthquakes, mountain torrents, and mudslides have occurred frequently, which have also caused damage to the water supply system. Drinking water sources have been polluted by sediment. It is difficult to guarantee drinking water, and drinking water safety has attracted much attention. In response to this problem, if defensive measures cannot be taken in time, it will pose a huge threat to the ecological environment and the safety of people's lives and property. [0003] For high turbidity water with high sand content, the traditio...
