Precision rainwater flow abandoning, filtering and storing integrated tank

Abstract

The invention discloses a precision rainwater flow abandoning, filtering and storing integrated tank which comprises a tank body, and a flow abandoning device and a filtering well which are arranged on the tank body. A water inlet is formed in the flow abandoning device. The flow abandoning device is communicated with the filtering well through a liquid guiding opening. The filtering well is communicated with the interior of the tank body through a rainwater collection pipe. The precision rainwater flow abandoning, filtering and storing integrated tank has the advantages that on the basis of initial rainwater flow abandoning values planned by cities, the functions of precision rainwater flow abandoning, filtering, storing and leaking can be achieved, flood draining safety can be effectively ensured, the structure is compact and reliable, and maintenance is convenient.

Description

technical field [0001] The invention relates to a rainwater storage device, in particular to a device which is arranged underground and integrates rainwater disposal, filtration, storage and leakage. Background technique [0002] In the past, the idea of ​​urban construction to solve the problem of rainwater drainage was to quickly discharge block, collect it through the ground stormwater outlet, drain it into the municipal rainwater pipe network system, and finally divert it to natural waters. This treatment method does not consider the collection and reuse of rainwater, which wastes natural resources, and does not set up storage and purification facilities. In the heavy rainfall environment, the garbage and sundries involved in the pipeline system by rainwater not only easily block the pipeline, It will also cause environmental pollution to natural waters. [0003] In order to solve the above problems, the country has proposed the concept of "sponge city", which is a new ...

Problems solved by technology

[0004] The idea of ​​storing and utilizing rainwater in the prior art is to store it in large-scale storage tanks, and then transport it through pipelines or transfer tools when needed. Such large-scale storage tanks have high maintenance costs, and rainwater volatilization and transportation The degree of waste such as consumption is relatively serious, and the real energy saving and environmental protection and the full utilization of resources have not been achieved
