Technical Field

There are many methods for water purification, including physical, chemical and biological methods, and the effects and usage scenarios of various methods are different.

[0003] When supplying water to rural areas, small communities, remote areas, etc., local water sources are generally used for direct water supply. Water in the natural environment is mixed with a large amount of impurities, and it needs to be filtered and purified before water supply. Chinese Patent Publication No. CN 204138402 U discloses a water purification device, which belongs to the technical field of water treatment equipment. The utility model provides a water purification device with good water quality and reasonable structure, including a flocculation reaction zone and a sedimentation zone. The lower part of the flocculation reaction zone is connected to the lower part of the sedimentation zone. Mud discharge valves are provided at the bottom of the flocculation reaction zone and the bottom of the sedimentation zone. A water collection weir is connected to the water inlet of the filter through a water seal and a water seal pipe. The water outlet of the filter is connected to the filter tank through an outlet pipe.

[0004] The above-mentioned water purification equipment uses a flocculation reaction zone and a sedimentation zone to perform preliminary filtration and purification on the water, and then transfers the water into a filter tank for further filtration; however, water bodies in the natural environment are not only mixed with particulate impurities, but also contain substances at the molecular level that cannot be filtered out by physical methods alone. Water containing such substances is not suitable for drinking and will cause harm to the body; the above-mentioned water purification equipment cannot remove harmful substances at the molecular level from the water body, resulting in poor purification effect on the water body.
