Problems solved by technology

Although the physical purification method is effective, it requires the user to properly store and maintain the filter material. If it is not stored properly, the results of field drinking water purification and disinfection may be invalid.
Moreover, the water production rate and water production rate of physical purification are relatively low, which will limit its scope of application.

Embodiment 1

[0048] Take 5L of Yellow River water in a folded water bag, add 25mg of detoxifying agent into the water bag after dissolving it in a medicine dissolving cup, and stir evenly. Then take 100mg each of the coagulant and the pH regulator, pour it into the medicine dissolving cup, and fully dissolve it with the water to be treated. Use a stirring rod to stir at a rate of 200r / min until a vortex is formed, pour the dissolved coagulant and pH regulator solution into the water bag, and continue to stir in the same direction at a rate of 200r / min for 2min, then along the In the same direction, reduce the speed to 60r / min and keep stirring for 1min. Stop stirring, take out the stirring rod, and let stand for 15min. Bind the filter cloth to the outlet of the water bag for filtration, and use the residual chlorine meter, turbidity meter, and pH meter to test the water quality. The test results: the turbidity is 3.6NTU, and the free residual chlorine concentration is 3.1mg / L , the pH is...

Embodiment 2

[0050] Take 10L of water from Miyun Reservoir in a folded water bag, and add loess to artificially prepare turbid water. Dissolve 200mg of detoxifying agent in a medicine dissolving cup, add it to the water bag, and stir evenly. Then take 500mg each of the coagulant and the pH regulator, pour them into the medicine dissolving cup, and fully dissolve them with the water to be treated. Use a stirring rod to stir at 150r / min until a vortex is formed, pour the dissolved coagulant and pH regulator solution into the water bag, and continue to stir rapidly in the same direction at 150r / min for 3min, and then in the same direction Reduce the rotation speed to 80r / min and keep stirring for 2min. Stop stirring, take out the stirring rod, and let stand for 10min. Bind the filter cloth to the outlet of the water bag for filtration, and use the residual chlorine meter, turbidity meter, and pH meter to test the water quality. The test results: the turbidity is 4.5NTU, and the free residua...

Embodiment 3

[0052] Take 8L of rainwater storage water in the water bag, add loess to artificially prepare turbid water. Dissolve 80mg of detoxifying agent in the medicine dissolving cup, add it into the water bag, and stir evenly. Then take 480mg each of the coagulant and the pH regulator, pour them into a medicine dissolving cup, and fully dissolve them with the water to be treated. Use the assembled stirring rod to stir at 250r / min until a vortex is formed, pour the dissolved coagulant and pH regulator solution into the water bag, and continue to stir at 250r / min in the same direction for 4 minutes, and then along the same direction Reduce the rotational speed to 100r / min and keep stirring for 4min. Stop stirring, take out the stirring rod, and let stand for 5min. Bind the filter cloth to the outlet of the water bag for filtration, and test the water quality with a residual chlorine meter, a turbidity meter, and a pH meter. The test results: the turbidity is 3.2NTU, and the concentrat...

Abstract

The invention provides field drinking water purification and disinfection equipment. The equipment comprises a backpack, a folding bucket, a medicine dissolving cup, a stirring rod, a coagulant, a pHregulator, a disinfectant, a filter cloth and a water quality analyzer. Accordingly, the coagulant, the pH regulator and the disinfectant are used for treating field drinking water, partial soluble pollutants, colloidal particles and tiny suspended solids in water can be removed through flocculation, sedimentation and filtration, and the field drinking water is disinfected; the water quality analyzer is used for detecting the water quality obtained after treatment, and the drinking safety of purified water can be guaranteed; the disinfection equipment is easy to carry, the practicability is high, and requirements of field operation, travel, outdoor adventures and other activities can be met. Meanwhile, the invention provides an application method of the field drinking water purification and disinfection equipment. The method is easy to implement, and large-volume safe drinking water can be obtained rapidly.

Description

technical field [0001] The invention relates to the technical field of drinking water purification and disinfection, in particular to a field drinking water purification and disinfection equipment and an application method thereof. Background technique [0002] Water is an important medium to support life systems, and safe drinking water is the basic guarantee for realizing the life support ability of water. At present, the construction of municipal drinking water security capacity can basically meet people's daily needs. However, under conditions such as sudden natural disasters, when the daily water supply system is damaged and cannot work normally, people's drinking water safety will be seriously threatened, and sometimes there is even a situation where there is no safe drinking water available in the face of a large amount of water. At this time, convenient and efficient drinking water purification and disinfection technology and equipment have become the key to drinkin...
