Description
Technical Field
The invention relates to the technical field of rainwater collection, in particular to an assembled rainwater flower box with initial rainwater purification and a water purification method using the assembled rainwater flower box.
Background
When rainwater flows from the downpipe to the ground drainage well, a large amount of pollutants are inevitably carried in the rainwater. If the sewage is directly discharged, the municipal pipe network is easy to block; moreover, a large amount of rainwater is directly discharged into a municipal pipe network, so that the load of a river water system is increased, and even the ecological environment is damaged; in addition, water resources are directly discharged to the nature and cannot be effectively utilized, thereby causing great waste. It is necessary to connect a device having a function of filtering pollutants in rainwater between a rainwater downpipe and a ground drain of a building.
The existing flower box only has the function of beautifying the landscape, and is difficult to achieve the purposes of water purification, water storage and recycling. Rainwater collected by the downpipe is directly discharged through the ground drain, so that the drainage load in the municipal pipe network is greatly increased. The existing flower box does not have the separation treatment capacity for rainwater collected by the downpipe of the existing building. If the rainwater collected by the downpipe is buffered by the plants in the flower box, the rainwater is discharged to a municipal pipeline. Although the rainwater collected in the downpipe can play a part of buffering role on municipal pipelines after passing through the flower box, the energy of the rainwater in the downpipe is not beneficial to plant growth because the rainwater continuously washes the planting matrix in the flower box, and further the functions of water purification and water storage of the flower box are influenced.
Through search, chinese patent document CN211607516U discloses an assembled modular rainflower box. The rainwater flower box comprises a box body, a building downpipe, a rainwater filtering module, a water storage module, a planting soil module, a concrete pool wall module, an overflow pipe assembly and a partition plate assembly. The baffle plate component is fixed in the box body to form a cavity. The rainwater filtering module is arranged in the cavity. The water storage module and the concrete pool wall module are arranged under the planting soil module according to the sequence. The building downpipe passes through the planting soil module and is communicated with the cavity. The overflow pipe assembly is arranged in and fixed in the box body. The overflow pipe assembly is communicated with the rainwater filtering module and the water storage module at the same time.
However, the above-mentioned rainflower tank does not have a device for preventing rainwater collected in the downpipe from washing the planting substrate in a large amount. And, lack rapid Assembly's structure between planting, filtration and the retaining module in the rainwater flower case, the cost of installation and maintenance is higher.
For another example, chinese patent document CN206879565U discloses a wood-plastic flower box. The bottom of the box both sides of this flower case is moulded to wood has all seted up the inlet opening. The surface of the box body is fixedly connected with a water collecting tank. The inner cavity of the box body is fixedly connected with a clapboard. The surface of the clapboard is provided with a through hole. The front and the back of the inner wall of the box body are fixedly connected with sliding rails below the partition plate. The inner cavity of the box body is provided with a filter plate below the partition plate. The front and the back of the filter plate both extend to the inner cavity of the slide rail. The left side of filter runs through the box and extends to the outside of box. The wood-plastic flower box also lacks the function of energy dissipation on rainwater collected in the downpipe.
In summary, how to design a rainwater flower box for connecting a downpipe and a ground row in the rainwater treatment process of collecting the downpipe by utilizing the flower box is used for dissipating energy of rainwater, reducing the reconstruction cost of municipal pipelines, facilitating the combined assembly of workers during construction, and further improving the installation efficiency, and thus the technical problem to be solved by the technical personnel in the field is urgently solved.
