Rain and flood utilization system

Abstract

The invention discloses a rain and flood utilization system, which integrates project measures and ecological environment, is widely applied to the technical field of rain water utilization and particularly relates to the rain and flood utilization system in building zones. The whole process of the rain and flood utilization system is completed through rain water converging, safe diversion, abandoned flow control, filtration, storage, water quality keeping, purifying treatment and comprehensive utilization. The system has a security function of automatic alarm, avoids blockage and siltation, ensures smooth filtration, reduces potential safety hazard, realizes quaternity integrated recycle treatment, namely sterilization, activation, filtration and oxygenation, of stored water, further guarantees the water quality, prevents secondary pollution of an impounding reservoir, reduces load of water quality treatment and saves investment and operation cost.

Description

technical field [0001] The invention is an organic combination of engineering measures and ecological environment, and is widely applicable to the technical field of rainwater utilization, and particularly relates to a rainwater utilization system in construction areas. Background technique [0002] With the progress of human society and technological development, especially due to the sharp contradictions of water shortage and ecological environment deterioration brought about by modern society and urbanization, rainwater utilization technology is gradually being paid attention to. At present, the rainwater collection and reuse system is generally composed of rainwater collection and storage, rainwater purification and treatment and rainwater utilization. But there are some deficiencies in varying degrees, such as: [0003] 1. Traditional abandonment wells and abandonment ponds cannot realize automatic control, cannot determine the appropriate abandonment flow rate accordi...

AI Technical Summary

Problems solved by technology

[0003] 1. Traditional abandonment wells and abandonment ponds cannot realize automatic control, and cannot determine the appropriate abandonment flow rate according to different rainfall conditions, and have poor water quality control capabilities; they are not easy to clean and easy to block

In addition, when the catchment surface is large, a large pool capacity is required, which increases investment

[0004] 2. There may be water leakage in the electric valve and metering device of the automatic diversion collection system, which may also cause water leakage during maintenance

[0005] 3. The switching control of the electric valve is easy to fail. When there are large floating objects in the rainwater, such as branches, it is easy to block the pipeline, affecting the normal drainage, and causing a huge safety hazard to the system.

[0006] 4. The signal butterfly valve controls the discarded flow through the time signal, and the discarded flow pool controls the discarded flow through the volume. They all have no water quality monitoring function, resulting in unstable follow-up treatment load, and the effluent water quality is not easy to meet the standard, etc.

[0007] 5. There is no filtering facility in the process of discarding the flow, resulting in a large amount of sludge deposition in the reservoir, which requires regular cleaning and heavy workload

At the same time, there will be a large amount of sediment at the bottom of the reservoir, which will cause secondary pollution to the subsequent rainwater.
