Technical Field
The invention belongs to the technical field of rainwater filters, and particularly relates to a linear unpowered rainwater filter and a filtering method thereof.
Background
The urban water consumption is continuously increased, so that the urban water problem is more and more emphasized. Particularly, in southern cities, much rainfall exists, the rainfall is large, and rainwater is used as an available natural resource, so that the problem of shortage of urban water resources is greatly reduced by proper collection and storage. During rainfall, the rainwater on the road usually carries sundries to directly flow into urban drainage pipelines or green belts, so that the waste and pollution of water resources are caused.
China is one of the countries with serious water shortage all over the world, and after floods which are difficult to utilize and underground water resources which are scattered in remote areas are removed, the water resources available in China are fewer. Therefore, the recycling of rainwater is very important for China, and relevant data shows that more than 400 cities in our country have the problem of insufficient water supply, and many places have very sharp water resource supply and demand problems.
