System for deeply purifying rainwater

Abstract

The invention relates to a system for deeply purifying rainwater. The system comprises an initial rainwater abandoning device, a water reservoir, a pressure filtering tank, a water purifying device, an ultra-filtration membrane treating device, a water tank and a water feeding pump which are connected with each other in turn, wherein a water outlet of the initial rainwater abandoning device is communicated with the water reservoir; the water reservoir and the pressure filtering tank are communicated with each other through a pressure conveying pipeline; the water outlet of the pressure filtering tank is communicated with a water inlet of the water purifying device; the water outlet of the water purifying device is communicated with the water inlet of the ultra-filtration membrane treating device; the water outlet of the ultra-filtration membrane treating device is connected with the water inlet of the water tank; and water in the water tank is conveyed to a user by the water feeding pump.

Description

technical field [0001] The invention relates to a rainwater deep purification treatment system, which belongs to the field of water treatment. Background technique [0002] For tropical islands in the South China Sea, the island has a lot of precipitation but lacks water storage facilities. Fresh water is mainly transported from other places by local islanders and partially collected by pots and pans. The ability to maintain fresh water resources is very low, making The life of the islanders is often troubled by the difficulty of draft and water. Considering the geographical environment and the number of permanent residents in the reef islands in the South China Sea, the cost of land-based water diversion is huge and cannot benefit the reef islands. Seawater desalination also has problems of high cost, large power consumption, and difficulty in sustaining. In this case, the combination of eaves rainwater collection and rainwater treatment is adopted to fundamentally solve t...

Considering the geographical environment and the number of permanent residents in the reef islands in the South China Sea, the cost of land-based water diversion is huge and cannot benefit the reef islands. Seawater desalination also has problems of high cost, large power consumption, and difficulty in sustaining. In this case, the combination of rainwater collection and rainwater treatment on the eaves is adopted to fundamentally solve the problem of difficulty in draft and water for the islanders
