Problems solved by technology

[0002] At present, the health of drinking water has received great attention all over the world. In order to remove harmful substances such as bacteria, microorganisms and heavy metals in water, all human beings are doing their best to explore methods, such as high temperature, bleaching and other methods are widely used, but they cannot Thoroughly remove impurities in water; filter cotton, activated carbon and other means of filtration are also extremely limited, and cannot play a role in impurities with small or finer molecular volumes and heavy metals
The effect of reverse osmosis filtration device is slightly better, but there are problems of complicated use and high cost

Embodiment Construction

[0014] The thinking of the present invention to solve the technical problem is to uniformly fix the chitosan on the surface or inside of the filter base, and the filter base is cloth, plastic, paper or metal mesh. Water is filtered with the chitosan filter membrane. Chitosan is a substance extracted from the shells of crustaceans such as shrimps and crabs. It is a white or off-white translucent flake or powder solid, tasteless, odorless, and non-toxic. Pure chitosan has a slight Pearly luster. Chitosan has three different viscosities, that is, high-viscosity products are 0.7-1Pa·s, medium-viscosity products are 0.25-0.65Pa·s, and low-viscosity products are <0.25Pa·s.

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the chitosan (2) is pressed or coated on the surface of the filter base layer (1), and the chitosan is a high-viscosity product, that is, 0.7-1 Pa·s. The filter base...

Abstract

The invention provides a chitosan filtering membrane. The chitosan filtering membrane can be used for filtering water by means of uniformly fixing chitosan on the surfaces or the internal parts of filtering base layers due to a characteristic of strong absorption capability of the chitosans. The used filtering base layer is made of cloth, plastic, paper or a metal net. The chitosan can be clamped between the two filtering base layers or mounted in a bag formed by the filtering base layers; and the chitosan contained in the bag is particle-shaped or powder-shaped. The chitosan filtering membrane provided by the invention can be used for effectively filtering harmful matters, such as bacterium, microorganism and heavy metal. Tap water, well water and underground water filtered by the chitosan filtering membrane provided by the invention can be directly drunk.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a chitosan filtration membrane. Background technique [0002] At present, the health of drinking water has received great attention all over the world. In order to remove harmful substances such as bacteria, microorganisms and heavy metals in water, all human beings are doing their best to explore methods, such as high temperature, bleaching and other methods are widely used, but they cannot Thoroughly remove impurities in water; filter cotton, activated carbon and other means of filtration are also extremely limited, and cannot play a role in impurities with small or finer molecular volumes and heavy metals. The effect of adopting the reverse osmosis filter device is slightly better, but there are problems of complicated use and high cost. Contents of the invention [0003] In view of the problems referred to above, the present invention provides a chitosan filtratio...
