Embodiment 1

[0021] The treatment object is a river water polluted by heavy metals, the arsenic content in the water is 2ppm, COD Mn It is 8ppm, and the conductivity is 450us / cm.

[0022] The high-flux permeable membrane used in the inner bag is prepared according to the following method: add a certain amount of graphene oxide and carbon nanotubes to 12% polyacrylonitrile dimethylformamide solution, the amount of graphene added is 0.05%, carbon nanotubes The amount of tube added is 0.05%. After ultrasonic dispersion, use electrospinning to spin to obtain a nanofiber composite film. The thickness of the nanofiber composite film is controlled by spinning time to 100 microns, and then immersed in a 1.5% m-phenylenediamine aqueous solution for 5 minutes. Air removes excess MPD solution on the surface of the base film, drains, and then immerses in a n-hexane solution with a mass fraction of 0.1% trimesoyl chloride for interfacial polymerization for 1 min, rinses the residual n-hexane solvent on...

Embodiment 2

[0025] The treatment object is a river polluted by heavy metals, the chromium content in the water is 10ppm, the COD Mn It is 20ppm, the conductivity is 450us / cm, and the Escherichia coli is tens of thousands / liter.

[0026] The high-flux permeable membrane used in the inner bag is prepared as follows: add a certain amount of graphene oxide and carbon nanotubes to 15% polyacrylonitrile dimethylformamide solution, the amount of graphene added is 0.05%, carbon nanotubes The amount of tube added is 0.15%. After ultrasonic dispersion, use electrospinning to spin to obtain a nanofiber composite film. The thickness of the nanofiber composite film is controlled by spinning time to 70 microns, and then immersed in a 1.5% m-phenylenediamine aqueous solution for 5 minutes. Air removes excess MPD solution on the surface of the base film, drains, and then immerses in a n-hexane solution with a mass fraction of 0.1% trimesoyl chloride for interfacial polymerization for 1 min, rinses the re...

Embodiment 3

[0029] The object of treatment is a certain bittern, the conductivity is 4500us / cm.

[0030]The high-flux permeable membrane used in the inner bag is prepared according to the following method: add a certain amount of graphene oxide and carbon nanotubes to 14% polyacrylonitrile dimethylformamide solution, the amount of graphene added is 0.05%, carbon nanotubes The amount of tube added is 0.10%. After ultrasonic dispersion, use electrospinning to spin to obtain a nanofiber composite film. The thickness of the nanofiber composite film is controlled by spinning time to 80 microns, and then immersed in a 1.5% m-phenylenediamine aqueous solution for 5 minutes. Air removes excess MPD solution on the surface of the base film, drains, and then immerses in a n-hexane solution with a mass fraction of 0.1% trimesoyl chloride for interfacial polymerization for 1 min, rinses the residual n-hexane solvent on the film with ethanol, and places it at 25°C for 30 min, then uses After rinsing wi...

Abstract

The invention relates to an outdoor portable emergency drinking water device and an application method thereof and belongs to the field of drinking water treatment. The emergency drinking water device is used for solving the problems that the existing emergency drinking water purifying device is difficult to carry and cannot in-situ prepare drinking water at any time and any place and aims at providing the outdoor portable emergency drinking water device based on a high-throughput antimicrobial forward-osmosis membrane; and by the device, direct drinkable water can be in-situ prepared from any water source at any time and any place so as to meet the emergency needs. The treatment cost is low, the device is convenient to carry and the good treatment water quality is achieved.

Description

technical field [0001] The invention belongs to the field of drinking water treatment, and in particular relates to an outdoor portable emergency drinking water device and a using method thereof. Background technique [0002] Due to industrial development and population growth, the discharge of industrial and domestic sewage has seriously polluted surface water and groundwater. Surface water or easily accessible shallow groundwater usually does not meet drinking water standards and needs to be purified. On the other hand, surface water and easy-to-obtain shallow groundwater are extremely susceptible to microbial contamination, containing microorganisms such as bacteria and viruses, making the raw water unable to meet the standard of direct drinking water. [0003] In the wild, such as special operations, earthquakes, and emergency rescue scenarios, due to ultrafiltration and reverse osmosis equipment, the equipment is generally too large to meet emergency use. At the same ti...
