technical field

The utility model belongs to the technical field of rainwater treatment and reuse, and in particular relates to an integrated system for rainwater collection, purification and reuse in a residential area.

Background technique

In recent years, due to the development of urbanization, there are more and more hardened roads and roofs in the city, resulting in the reduction of urban green space. When heavy rainfall occurs, the rainwater is collected and quickly discharged into the rainwater pipes. On the one hand, it brings huge pressure to the urban drainage system. On the other hand, rainwater is a precious resource. Big waste.

Utility model content

In view of the above problems, the technical problem to be solved by this utility model is to provide an integrated system of rainwater collection, purification and reuse in residential areas, which can not only reduce the pressure of rainstorm runoff on the urban drainage system, but also reuse rainwater resources .

The technical problem to be solved by the utility model is achieved through such a technical scheme, which includes a green roof, a side ditch infiltration system and an intensified treatment pool, the green roof is connected to the intensified treatment pool through a rainwater pipe, and the side ditch infiltration system is passed through The collection channel or pipeline is connected to the enhanced treatment pool.

Due to the adoption of the above technical scheme, during heavy rain, the rainwater on the road is initially treated by the gutter infiltration system, the rainwater on the roof is purified by the plants and soil on the green roof, and the rainwater is collected from the gutter infiltration system and the green roof. In the enhanced treatment pool, part of the rainwater is stored after further enhanced treatment. In this way, on the one hand, the runoff coefficient of the community is reduced, thereby reducing the pressure on the rainwater pipe network; on the other hand, the collected rainwater is treated and stored to realize the reuse of rainwater resources.

The utility model has the following advantages: it can not only reduce the runoff coefficient of the residential area, thereby reducing the pressure on the rainwater pipe network, but also realize the reuse of rainwater resources. Used for flushing the pavement of the community.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, the utility model includes a green roof 1, a side ditch infiltration system 3 and an enhanced treatment pool 4, the green roof 1 is connected to the enhanced treatment pool 4 through a rainwater pipe 17, and the side ditch infiltration system 3 is passed through a water collection canal Or the pipeline is connected to the strengthened treatment pool 4.

During heavy rain, the rainwater on the road 2 is preliminarily treated by the gutter infiltration system 3, the rainwater on the roof is purified by the plants and soil on the green roof 1, and the rainwater is collected from the gutter infiltration system 3 and the green roof 1 for intensive treatment In the pool 4, part of the rainwater is stored after intensive treatment.

As shown in Figure 2, the side ditch infiltration system 3 is provided with a rainwater grate 5, a pebble layer 6, a gravel layer 7 and a water collection channel 8 from top to bottom, and a certain amount of water is left between the rainwater grate 5 and the pebble layer 6. space. When the runoff collected by the road 2 is small, the runoff flows into the catchment channel 8 through the interception of the pebble layer 6 and the filtration of the gravel layer 7, and then flows into the intensive treatment pool 4 through the catchment channel 8; when the runoff of the road 2 is large, the redundant The runoff overflows into the rainwater pipe through the space between the rainwater grate 5 and the cobblestone layer 6, and is discharged by the urban drainage system. The connection between the percolation system 3 and the enhanced treatment pool 4 can also be connected by pipelines.

As shown in FIG. 3 , the green roof 1 is provided with a vegetation layer 9 , a synthetic soil layer 10 , a gravel layer 11 and a structural layer 12 from top to bottom. When it rains, the rainwater is filtered and adsorbed by the vegetation layer 9, the synthetic soil layer 10 and the gravel layer 11 to purify the rainwater, and the intercepted pollutants are degraded by microorganisms and absorbed by the roots of the plants. The gravel layer 11 infiltrates into the rainwater bucket 13, and then flows into the enhanced treatment pool 4 through the rainwater pipe 17.

As shown in Figures 1 and 4, the enhanced treatment pool 4 includes a filter area and a reservoir 16, wherein the filter area has a sedimentation tank and a filter material layer 15, and the outside of the filter area is a sedimentation tank, and the mouth of the sedimentation tank is provided with a grid. Grid 14, the side of the filter area facing the reservoir is a filter material layer 15, and the outlet hole at the bottom of the filter material layer 15 communicates with the reservoir 16.

The rainwater from the preliminary treatment of the gutter infiltration system 3 and the rainwater from the green roof 1 pass through the grille 14 and settle again in the sedimentation tank. In the material layer 15, rainwater infiltrates from top to bottom in the filter material layer 15, implements filtration, and enters the water storage tank 16 through the outlet hole at the bottom of the filter material layer 15.

During heavy rainfall, if the water level in the enhanced treatment pool 4 reaches the set water level, the excess runoff will overflow into the urban drainage system or the green space through the overflow pipe.

The grid 14 in the intensive treatment tank 4 adopts a 4-6 mesh fine grid or a filter screen, and a sand settling bucket is arranged under the sedimentation tank, and the sedimentation tank and the filter material layer 15 are separated by a plastic partition, and the upper part of the plastic partition has holes. The sand settling hopper in the sedimentation tank and the filter material module in the filter material layer 15 can be disassembled. When there is a lot of sand settling and need to be cleaned, or when the filter material needs to be replaced, the module can be manually lifted out to clean or replace with a new filter material , be provided with sump in the reservoir 16, place water pump when supplying and reusing rainwater.

In the utility model, the accumulated water in the road 2 flows into the side ditch infiltration system 3, and the rainwater is preliminarily treated under the effects of filtration, adsorption, ion exchange, etc. of the side ditch infiltration system 3; It is purified under the comprehensive action of chemistry-biology-ecology; it flows into the enhanced treatment pool 4 in two directions, settles and filters in the enhanced treatment pool 4, and finally stores it in the reservoir 16 of the enhanced treatment device for watering green spaces and washing road use.
