[0003] In fact, this concept corresponds to the rainwater collection and recycling system in the prior art. Most of the rainwater collection and recycling methods and systems in the prior art simply involve the collection of rainwater pools for output and utilization without excessive processing. It cannot be used in more fields

Embodiment 1

[0054] A rainwater collection and recycling method, which includes the following steps:

[0055] S1. Use the roof rainwater collection system and the ground runoff rainwater collection system to collect rainwater into the buried sedimentation tank and settle for 24 hours to form a primary water storage;

[0056] S11. The roof greening absorbs rainwater and filters it through the soil, and slowly penetrates into the interception and retention system;

[0057] S12. The interception and retention system filters the rainwater to further filter out the sediment;

[0058] The rainwater after S13 and S12 enters the roof reservoir for water storage.

[0059] S2. Use a pump to transfer 60% of the first-level storage water in the upper layer of the sedimentation tank to the first-level storage tank for re-precipitation. The precipitation time is 12 hours to form the second-level storage;

[0060] S3. Use a pump to transfer 60% of the secondary storage water in the upper layer of the above-mentione...

Embodiment 2

[0065] A rainwater collection and recycling method, which includes the following steps:

[0066] S1. Use the roof rainwater collection system and the ground runoff rainwater collection system to collect rainwater into the buried sedimentation tank and settle for 30 hours to form a primary water storage;

[0067] S11. The roof greening absorbs rainwater and filters it through the soil, and slowly penetrates into the interception and retention system;

[0068] S12. The interception and retention system filters the rainwater to further filter out the sediment;

[0069] The rainwater after S13 and S12 enters the roof reservoir for water storage.

[0070] S2. Use a pump to transfer 50% of the first-level storage water in the upper layer of the sedimentation tank to the first-level storage tank for re-precipitation. The precipitation time is 15 hours to form the second-level storage;

[0071] S3. Use a pump to transfer 50% of the secondary storage water in the upper layer of the above-mentione...

Abstract

The invention discloses a rainwater collecting and recycling method. The method comprises the following steps: collecting rainwater into a buried sedimentation tank by virtue of a roof rainwater collection system and a surface runoff rainwater collection system, so as to form primary stored water; introducing 50-60% of the primary stored water in the upper layer of the sedimentation tank into a primary reservoir by virtue of a water pump, so as to form secondary stored water; introducing 50-60% of the secondary stored water in the upper layer of the primary reservoir into a secondary reservoir by virtue of a water pump, so as to form tertiary stored water; and introducing 80-90% of the tertiary stored water in the upper layer of the secondary water reservoir into a tertiary reservoir by virtue of a water pump, so as to form quaternary stored water. The method provided by the invention has functions of 'intercepting', 'absorbing', 'maintaining', 'purifying' and 'releasing' the rainwater, and the like, so that novel urbanized municipal facilities have excellent 'elasticity' in such aspects as adapting to environmental change, responding to natural disasters and the like. The method is energy-saving and environment-friendly.

Description

Technical field [0001] The invention relates to the technical field of rainwater collection and recycling, and a method and system for rainwater collection and recycling. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called "water elastic city". [0003] In fact, this concept corresponds to the rainwater collection and recycling system in the prior art. The rainwater collection and recycling method and system in the prior art mostly simply involve the output and utilization of the rainwater pool after collection, without excessive processing. It cannot be used in more fields. [0004] Therefore, the field needs to be improved. Summary of the invention [0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a ra...
