Problems solved by technology

[0003] Typical surface water treatment methods are coagulation, sedimentation, and filtration. Traditional water supply and purification devices and technologies are applied in villages and towns, and it is difficult to adapt to the characteristics of scattered villages and towns and low management levels.
Moreover, the current equipment needs to build reaction sedimentation tanks and filter tanks, which occupy a large area and high infrastructure costs; the degree of automation is low, and professional management and maintenance are required, which increases the cost of daily operation, maintenance and maintenance.
[0004] At present, the disadvantages of the traditional water supply treatment method are that it occupies a large area, the cost of infrastructure construction is high, the degree of automation is low, and the cost of daily operation, maintenance and maintenance is increased. It is not suitable for the application in the case of scattered villages and towns. There is a certain relationship that the village does not have access to tap water; moreover, the water treatment method is fixed and single, and cannot be adjusted according to the situation of the water source
