Description

Integrated rainwater collection and utilization device

technical field

The utility model relates to a rainwater collection and utilization device.

Background technique

my country is a country seriously short of water resources. The per capita water resources are only a quarter of the world's per capita. When the traditional water resources development methods can no longer increase water resources, recycling rainwater has become an economical and practical method. way of water resource development. The rainwater is collected and treated for direct use, mainly used for urban green space irrigation, road surface spraying, landscape water replenishment, etc., which can effectively relieve the pressure of urban water supply. At present, my country's rainwater utilization technology is still in its infancy. There are many disadvantages in rainwater collection and treatment facilities, which make the rainwater quality poor. The treatment facilities are blocked due to the long-term deposition of sediment in the rainwater, which affects the use.

Utility model content

In order to solve the above problems in the treatment facilities, the utility model provides an integrated rainwater collection and utilization device, which integrates the collection, treatment, storage and utilization of rainwater. The device uses the pool assembled by PP modules to store rainwater, and then purifies it through the filter layer at the bottom of the pool. Sediment buildup in stormwater clogs the filter system.

In order to achieve the above object, the utility model adopts the following technical solutions:

An integrated rainwater collection and utilization device, including a water distribution well and a storage tank, the water distribution well is connected to the storage tank through a water distribution pipe, the bottom of the storage tank has a filter layer, and a water collection pipe is laid on the bottom of the filter layer, and the water collection pipe is collected into An intake well located in a cistern.

A flushing pipe is laid in the middle of the filter layer, and the flushing pipe is collected into a sewage well located in the reservoir.

A sewage pipe is laid on the upper part of the filter layer, and the sewage pipe communicates with the sewage well.

The reservoir is assembled from plastic modules.

The filter layer includes a filter plate and a sand filter layer, the filter plate is located at the upper part of the filter layer, and the sand filter layer is located at the lower part of the filter layer.

A water supply pump and a water supply pipe are arranged in the water intake well.

A sewage pump and a mud discharge pipe are arranged in the sewage well.

The impermeable geotextile is wrapped around the reservoir.

The utility model collects rainwater to a pool assembled by PP plastic modules through a water distribution well. The bottom of the pool is connected with the filter layer, and the rainwater is directly purified through the filter layer by gravity. The bottom of the filter layer is laid with a water collection pipe, a flushing pipe, and a sewage pipe. Pipelines rely on different elevations to complete their respective functions.

The beneficial effect of the utility model is that the collection pool is also a storage pool, which saves land occupation; the rainwater is fully purified through layer-by-layer filtration, and fully meets the water quality standards of miscellaneous water; the system is equipped with flushing pipes to ensure that the system will not be blocked for a long time.

Figure 2 is a schematic diagram of A-A in Figure 1

In the figure, 1. Water distribution well, 2. Water distribution pipe, 3. Sewage well, 4. Sewage pipe, 5. Water intake well, 6. Water supply pipe, 7. Water storage module, 8. Filter plate, 9. Sand filter layer, 10. Sewage pump, 11. Water supply pump, 12. Water collection pipe, 13. Sewage pipe, 14 flushing pipe.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

As shown in Figures 1 and 2, the rainwater entering the water distribution well 1 enters the reservoir 7 through the water distribution pipe 2. The rainwater in the reservoir 7 is first filtered by the filter plate 8 at the bottom of the reservoir by gravity, and then penetrates into the sand filter. The layer 9 is further filtered, and the purified rainwater finally passes through the water collection pipe 12 at the bottom of the sand filter layer 9, collects into the water intake well 5, and is sent to the water point by the water supply pump 11 and the water supply pipe 6 in the well. The sludge intercepted in the filter layers 8 and 9 is collected in the sewage well 3 through the sewage pipe 13, and is discharged to the municipal sewage pipe by the sewage pump 10 and the mud discharge pipe 4 in the well. The flushing pipe 14 in the filter layer regularly flushes the filter layer to prevent the filter layer from clogging. The anti-seepage geotextile 15 is wrapped around the whole structure. Wherein the water collection pipe 12 is located at the bottom, the flushing pipe 14 is located in the middle of the filter layer, and the sewage pipe 13 is located at the uppermost end of the filter layer.

The utility model integrates collection and storage pools, and can be filtered and cleaned online. After purification, the water quality is excellent, the system integration degree is high, and the occupied area is small.

Those skilled in the art will recognize that without departing from the protection scope of the present invention, various modifications, changes and combinations can be made to the above-mentioned embodiments, and it is believed that such modifications, changes and combinations are within the scope of original ideas. within the range.
