Double-gate mixed flow rainwater interception and storage device, system and method based on water quality monitoring

Abstract

The invention provides a double-gate mixed flow rainwater interception and storage device, system and method based on water quality monitoring. The double-gate mixed flow rainwater interception and storage device comprises an interception well with a water inlet pipe, an interception pipe and a discharge outlet; the interception pipe is provided with an interception valve, and the discharge port is provided with a downward opening type gate; water quality on-line monitoring equipment is mounted at the bottom in the interception well, a liquid level sensor is mounted on the upper part of the interception well, and a rain gauge and a controller are mounted outside the interception well; and the controller is correspondingly connected with the interception valve, the downward opening type gate, the water quality online monitoring equipment, the liquid level sensor and the rain gauge. The lower opening type gate and the water inlet gate of the regulation and storage tank can be controlled through real-time numerical values of water quality parameters and liquid levels, the phenomenon of combined system overflow pollution is reduced, the volume of the regulation and storage tank or the drainage capacity of a downstream sewage pipe network is reasonably utilized, and waste of the volume of the regulation and storage tank of a traditional design and waste of the regulation capacity of the sewage pipe network are reduced.

Description

technical field [0001] The present invention relates to the technical field of overflow pollution control of confluence system and mixed flow system, and intelligent water construction, and in particular to a double-gate mixed flow rainwater interception and storage device, system and method based on water quality monitoring, which is suitable for interception confluence system with large discharge outlets. drainage system. Background technique [0002] During the progress of the treatment of black and odorous water bodies, it was found that during the urban rainfall process, the rainwater scoured the surface and brought a large amount of pollutants. If it is not treated, it will cause pollution to the natural water bodies in the city. This has become a factor that cannot be ignored in environmental governance. [0003] At present, the engineering measures to solve the overflow pollution of the combined system mainly rely on the installation of overflow weirs and rainwater s...

Problems solved by technology

[0004] In order to overcome the defects and deficiencies existing in the prior art, the present invention proposes a new double-gate mixed-flow rainwater interception and storage device, system and method based on water quality monitoring, which can control the bottom opening through real-time numerical values ​​of water quality parameters and liquid levels. The gate and the storage tank inlet gate can reduce the overflow pollution of the confluence system, rationally use the volume of the storage tank or the drainage capacity of the downstream sewage pipe network, and reduce the waste of the volume of the traditionally designed storage tank and the regulation capacity of the sewage pipe network. waste
