Clean rainwater collection and purification apparatus

Abstract

A clean rainwater collecting-purifying device comprises 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 outer 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 is formed by 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 is characterized in 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; the water quality is safe, etc. 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 rainwater collecting, storing and purifying device that is cheap, efficient, convenient, clean and environmentally friendly. Background technique [0002] "Safe drinking water" means that the water consumption of drinking water and the hygienic indicators of water quality can meet the requirements. With the intensification of global drought and increasingly serious pollution, the problem of the lack of "safe drinking water" for human beings has become more and more serious. According to the World Health Organization report, "80% of human diseases are related to water. To reduce diseases and save lives, the most effective measure is to provide safe drinking water for everyone." The United Nations Millennium Development Goals have listed solving the problem of drinking water safety as an important content, requiring all member states to halve the proportion of people ...

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
