Rainwater collecting device and method for different confluence areas

Abstract

The invention discloses a rainwater collecting device for different confluence areas, which comprises a rainfall runoff collecting pipeline and a plurality of collectors, wherein the rainfall runoff collecting pipeline is formed by communicating a vertical section and a horizontal section, the upper end of the rainfall runoff collecting pipeline of the vertical section is communicated with an area collecting tray, and the rainfall runoff collecting pipeline of the horizontal section is simultaneously, equidistantly and sequentially communicated with each collector. The invention also discloses a rainwater collecting method for different confluence areas. The rainwater collecting method comprises the following steps of: firstly determining an average single rainfall and a maximum rainfall by utilizing such device according to rainfall references for many years in an implementation area; then setting the number of collectors and the depth of rainfall collected by a single container; setting a total rainfall depth of all collectors according to the maximum rainfall; setting a volume of a rainfall runoff collector according to the depth of the rainfall; and finally collecting rainwater. By adopting the device and the method, the rainfall water quality is collected precisely, the standard is unified, and the proper runoff confluence areas can be determined accurately.

Description

technical field [0001] The invention belongs to the technical field of hydrological detection, and relates to a rainwater collection device for different confluence areas; the invention also relates to a rainwater collection method for different confluence areas. Background technique [0002] With the increasing tension of urban water resources and the increasing environmental pressure, rainwater utilization has become an effective measure to solve the shortage of urban water resources. Reasonable collection and application of rainwater can not only control water pollution on the ground, but also replenish groundwater in time. In recent years, research on rainwater reuse has been actively carried out at home and abroad, and various rainwater treatment methods and reuse technologies have emerged. In order for rainwater to be fully and effectively treated and utilized, it is first necessary to clarify the types and concentrations of pollutants in the runoff process generated ...
