Single-household-type roof-rainwater-collecting rain-initial-flow-discarding water-quality-purifying nursing integrated device

Abstract

The invention provides a single-household-type roof-rainwater-collecting rain-initial-flow-discarding water-quality-purifying nursing integrated device. The device structurally comprises a flow discarding module, a purifying module and a nursing module. At a rain initial flow discarding stage, the volume of discarded flow can be adjusted through evaporated volume of discarded rainwater in a discarded flow tank, and the problem that the flow discarding is not thorough or rainwater resources are wasted caused by a certain volume of discarded flow is avoided. In the aspect of water quality purification, by using a biological slow filtration technology, the disadvantage of the traditional adsorption purification mode that the adsorption capacity of a filtering material is rapidly weakened withtime is overcome; a water quality purification module adopts a cheap filtering material, compared with the traditional biological slow filtration, the quality of water before aging of a biomembrane is guaranteed by virtue of the adsorption of the cheap filtering material, and water body is purified mainly by virtue of the biomembrane after the aging of the biomembrane. For water body nursing, anunderground burial type nursing mode is adopted, so that the rapid propagation of microbes caused by problems such as water volume evaporation, outside pollution, too high water temperature and sunshine irradiation is avoided, and the condition that water quality in a low-water season is not remarkably degraded and meets the requirements of drinking water on safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a single-family roof integrated device for collecting rainwater, first rain, discarding flow, and water quality purification and conservation. Background technique [0002] In some water-scarce areas, local residents collect rainwater as a source of drinking water. According to the different rain collecting surface, it can generally be divided into roof rain collecting, ground rain collecting, slope rain collecting and so on. Among these rain collection methods, the water quality of roof rain collection is generally the best, so it is widely used in water-scarce areas. In the initial stage of rainwater collection, the scouring and dissolution of rainwater makes it carry pollutants such as bird droppings, leaves, dust, etc. remaining on the rainwater collection surface. If the initial rainwater enters the rainwater collection pond, it will affect the water quality of the...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no integrated technology for rainwater collection on the roof, rainwater purification, and rainwater conservation

[0005] 2. In the existing initial rainwater discarding devices, the discarding flow rate of some devices is fixed, that is, the flow rate cannot be adjusted according to the rainfall frequency, so that the discarding flow rate is too large when the rainwater is frequent, resulting in waste of rainwater resources; the other part is to realize The discharge flow is adjusted according to the rainfall frequency, and electrical components including water quality sensors, water quality detectors and servo motors are used. These components are expensive to purchase, install, operate, and maintain, which affects their promotion; on the other hand, electronic components are damaged. , and even leakage occurs, which affects the adaptability, reliability and safety of its use

[0006] 3. Most of the existing rainwater purification devices use physical and chemical purification and disinfection methods to purify the rainwater quality, which is costly and requires relatively professional personnel to operate

[0007] 4. At present, some rainwater purification patents use bio-slow filtration technology, but because bio-slow filtration requires a certain amount of time to mature, most of these methods do not consider how to ensure the water quality before the bio-film matures, and some bio-slow filtration uses The high cost of filter materials cannot be obtained locally, which is not conducive to the promotion of poor and water-scarce areas

[0008] 5. The few integrated technologies for rainwater purification and storage are generally implemented on a large scale and are not suitable for single-family rainwater quality restoration and storage

[0009] 6. In addition, the above-mentioned technologies do not consider the water quality conservation of the purified water body, that is, in addition to the storage of the purified water body, the water body should not undergo significant water quality degradation during the storage process, and it is necessary to solve the problem of water use in the dry season in areas with uneven rainfall. While solving the problem, ensure the safety of drinking water in the dry season
