Embodiment Construction

[0029] Such as Figure 1-Figure 5 Shown is a rainwater well with purification and storage functions, including rainwater well grating 1, float valve 2, uneven gap water distribution plate 3, biological filler 4, water storage tank 5, seepage brick 6, overflow wall 7. Drainage pipeline 8, sedimentation tank 9, filter screen 10, weir plate 11, fine grid flap 12, channel between inner and outer wells 13, inner well 14 and outer well 15;

[0030] The inner well 14 is in the shape of a rectangular barrel;

[0031] The top of the inner well 14 is connected and fixed to the fine grid flap 12 with the float valve 2 through hinges;

[0032] The float valve 2 drives the fine grid flap 12 to rotate;

[0033] A weir plate 11 is provided between the wellhead side of the inner well 14 and the fine grid flap 12 to block suspended solids;

[0034] A settling tank 9 is provided below the fine grid flap 12;

[0035] A filter screen 10 is provided between the outlet of the settling tank 9 an...

Abstract

The invention relates to a rainwater well with purification and storage functions. The top of an inner well is fixedly connected with a fine screen overturning plate with a floating ball valve; the floating ball valve drives the fine screen overturning plate to rotate; a weir plate is arranged between one side of the well mouth of the inner well and the fine screen overturning plate; a sedimentation groove is formed below the fine screen overturning plate; a filtering net is arranged between an outlet of the sedimentation groove and the weir plate; a water distribution plate with uneven gaps is arranged below the sedimentation groove; biological filler is arranged in a cavity formed by the water distribution plate with the uneven gaps and the bottom of the inner well; an outer well built by water permeable bricks and a reservoir are arranged outside the inner well; channels between the inner well and the outer well are arranged at the two sides of the exterior of the inner well; the reservoir is internally provided with an overflow wall; a drainage pipeline is arranged at one side of the bottom of the reservoir; a rainwater well coarse screen is arranged at the top of the outer well. At the initial period, rain falls into the sedimentation groove in the upper portion of the inner well, the water level rises to drive a floating ball to rise to make the fine screen overturning plate closed, during long-time rainfall, rainwater directly flows into the reservoir through the channels between the inner well and the outer well and is mixed with treated rainwater at the initial period, and mixed rainwater flows into the reservoir for storage.

Description

technical field [0001] The invention relates to the technical field of rainwater purification, collection and utilization, in particular to a rainwater well with the functions of purification and storage. Background technique [0002] Rainwater recycling is an effective way to solve the shortage of water resources, and it is also an important part of the construction of sponge cities. The collection and utilization of rainwater can not only reduce the environmental pollution of initial rainwater, but also effectively prevent urban waterlogging. The most critical issue in rainwater harvesting and utilization is to separate the heavily polluted early rainfall from the late rainfall. At present, the common practice is to discard the initial rainwater, collect the later rainfall with better water quality, and reuse it after simple treatment. This approach is not a good solution to the environmental pollution of the initial rainfall. Contents of the invention [0003] In ord...
