Abstract

The invention is a rain water runoff quality testing and vacuum sampling device, which belongs to the water supplying and discharging filed of water conservancy project. The invention comprises a vacuum buffering bottle (12), a vacuum pump (14) and a plurality of rain water sampling devices with the same structure. The vacuum buffering bottle is connected with a vacuum pump and each rain water sampling device is communicated with the vacuum buffering bottle. The structure of the single water sampling device is that: the device comprises an outdoor rain water sampling bottle (15), an indoor rain water collecting bottle (4) and a rain water sampling bottle (7); the outdoor water sampling bottle and the indoor rain water collecting bottle are communicated with each other by an outdoor rain water collecting and drawing duct; the indoor rain water collecting bottle and the rain water sampling bottle are communicated by a connecting rain water sampling bottle duct. The indoor rain water collecting bottle is communicated with the vacuum buffering bottle through an indoor rain water collecting bottle vacuumizing duct. The indoor rain water collecting bottle is communicated with air through the indoor rain water collecting bottle airing duct. The invention has the advantages of solving the sampling problem at multiple places of rain water runoff and saving the labour of on-site sampling in rain.

Description

technical field [0001] The invention relates to a vacuum sampling device for rainwater runoff water quality monitoring, which belongs to the field of water supply and drainage of water conservancy projects. Background technique [0002] The feasibility and availability of urban rainwater utilization not only depends on the rainfall and temporal and spatial distribution of rainfall, but also depends on the water quality of rainfall runoff. The monitoring and analysis of rainfall runoff water quality is a basic work for urban rainwater utilization, and rainwater Whether the sampling is accurate, timely and reliable will directly affect the quality of the entire water quality monitoring work. In the past, in the monitoring of rainfall runoff water quality, people mostly used on-site manual sampling. It was difficult to ensure the uniform sampling time of each sampling point, and it was also difficult to grasp the accurate runoff time, which brought inconvenience to further anal...
