Clean rainwater collection and purification device

Abstract

A clean rainwater collection and purification device is mainly formed by combining a rainwater collecting pool, a rainwater filtering pool, a water collecting cellar and a water purifier. The device is characterized in that the rainwater collecting pool at least comprises a ground brick-wall embankment, an aqueduct, a hardened ground and a rolling flexible waterproof fabric arranged on the hardened ground; the peripheral edge of the hardened ground is surrounded by the brick-wall embankment and the aqueduct is arranged on at least one section between the hardened ground and the embankment; the hardened ground consists of at least one ground or a plurality of grounds which are arranged side by side and isolated by the aqueducts respectively; the aqueduct is connected with the rainwater filtering pool by a water transferring pipe; and the water collecting cellar is connected with the rainwater filtering pool by a water transferring pipe and is communicated with at least one water purifier by the water transferring pipe. The device has the characteristics that the collecting efficiency is high; the product cost is low; the structure is simple and reliable; the operation is easy; the device is portable, durable and environment-friendly; and the water quality is safe, and the like. The device can lead the three significant indexes of water-use quantity, health index and water-taking convenience of 'safe drinking water' to reach the standard simultaneously.

Description

technical field [0001] The invention relates to a device for collecting and purifying rainwater, in particular to a device for collecting, storing and purifying rainwater which is cheap, efficient, convenient, clean and environment-friendly. Background technique [0002] "Safe drinking water" means that the water consumption and water quality of drinking water can meet the requirements. With the intensification of global drought and increasing pollution, the problem of shortage of "safe drinking water" for human beings has become more and more serious. According to the report of the World Health Organization, "80% of human diseases are related to water. To reduce diseases and save lives, the most effective measure is to provide everyone with safe drinking water." The Millennium Development Goals of the United Nations have listed the problem of safe drinking water as an important content, requiring all member states to reduce the proportion of the population lacking safe dri...

AI Technical Summary

Problems solved by technology

Some collect more rainwater, but the rainwater collected from surface runoff has been seriously polluted, and the water quality is difficult to guarantee: such as Patent No. 03262756.4 "A Splicing Movable Rain Collection Surface", Patent No. 01209950.3 "A Water Cellar Water catchment for water storage"; some use various techniques to harden the ground (such as soil curing agent, surface sprayed silicone, etc.) to prevent rainwater from seeping

The quality of the rainwater collected by these hardened grounds is difficult to guarantee that it will not be polluted by human production and living activities. Among them, the pollution of various pathogenic bacteria and germs, high residual pesticides, chemical fertilizers, human and animal manure, etc. is even more difficult to avoid.

This type of technology has patent number ZL200310118985.X "a construction method for increasing flow and reducing roughness of solidified loess collecting surface"; there is also a "rainwater collection device" such as the publication number CN1752357A. Although the collected rainwater is relatively clean, it must be made larger. Larger area of ​​collecting surface, the required supporting frame must be used a lot, the cost will be greatly increased, and the operation and use are also very troublesome, and the ability to prevent strong winds is also very fragile. Due to poor wind resistance, it may be forced to stop rainwater collection activities, this technique is less practical
