Integrated initial rainwater draining well and method for draining rainwater

Abstract

The invention provides an integrated initial rainwater draining well, which is a device capable of draining certain millimeters of initial rainwater on an appointed water catchment panel and separating out later clean rainwater so as to greatly enhance the quality of the recycled rainwater. The integrated initial rainwater drainage well consists of a buried rainwater inspection well and a storage pool; the rainwater inspection well is connected with a water inlet pipe and a water outlet pipe; a bevel board precipitation structure is arranged at the bottom of the storage pool; a drainage pipe is arranged at a position a certain distance from the pool bottom; a lower sink and a flow baffle plate are arranged between the rainwater inspection well and the storage pool; at the highest water level, short flow is formed between the water inlet pipe and the water outlet pipe, so the later rainwater passes through the rainwater inspection well and directly enters the water outlet pipe to be recycled; the initial rainwater is drained in the storage pool; and after the rainwater runoff stops, the rainwater in the storage pool is slowly drained from the drainage pipe and stopped at the effective lowest water level. The integrated initial rainwater draining well has the advantages that: the structure is simple, the well operates in an unmanned way, a power supply is saved, the well is easy to maintain, polluted rainwater can be collected effectively, the drainage pipe is hardly blocked, the blocked drainage pipe is easy to smooth after being blocked and the buried drainage pipe is buried so that the appearance of the environment is not influenced.

Description

technical field [0001] The invention belongs to the fields of environmental protection technology and rainwater reuse, and in particular relates to an integrated initial rainwater abandonment well and an operation method. Background technique [0002] Through scientific and technological novelty research, there are currently few research reports, patents, and practical engineering applications on the separation of initial rainwater by the initial rainwater abandonment device at home and abroad, and the current design and application of the existing initial rainwater abandonment device is not wide, and it cannot achieve no energy consumption, It is not easy to block and does not need special management. [0003] Due to the leaching, scouring and transportation of pollutants in the catchment area by the initial rainwater, most of the pollutants in the entire rainfall are contained in the initial few millimeters of rainwater. Generally, the concentration of pollutants in runof...
