Initial rainwater collection time measuring device and method and preparation method

Abstract

The invention relates to an initial rainwater collection time measuring device. The device comprises a bearing groove, a guide sliding rail, a water storage tank, a flow guide cone, a pH sensor, a TOCsensor and a control circuit, wherein the water storage tank is embedded in the bearing groove and connected with the side wall of the bearing groove through the guide sliding rail, the upper end surface of the water storage tank is communicated with the flow guide cone, one pH sensor, one conductivity sensor, one turbidity sensor, one ORP sensor and one TOC sensor form a working group, at leastone working group is arranged on the inner surface of the flow guide cone, at least one working group is arranged on the inner surface of the water storage tank, and the control circuit is embedded inthe outer surface of the bearing groove. The measurement method comprises two steps, namely, equipment assembly and rainwater detection. On the one hand, effective monitoring and identification of initial rainfall in different use occasions and environments can be effectively met, on the other hand, the data detection and monitoring precision is high, the operation automation degree is high, andthus the initial rainwater identification and monitoring precision is greatly improved.

Description

Technical field [0001] The invention relates to an initial rainwater collection time measuring device, method and preparation method, and belongs to the technical field of water quality surveying. Background technique [0002] Initial rain generally refers to precipitation that has formed surface runoff with a thickness of 10-15 mm on the ground. At the beginning of the rain, the rainwater dissolved a large amount of acid gas, automobile exhaust, factory exhaust and other polluting gases in the air. After it fell on the ground, it also washed the roof and asphalt concrete roads, which caused a lot of pollutants in the early rain. The degree of pollution is relatively high, even exceeding that of ordinary urban sewage. Directly discharged into the river through the rainwater pipe, causing a certain degree of pollution to the water environment. Therefore, in the recycling of rainwater resources, it is very susceptible to initial rainwater pollution, which may cause pollution and c...

AI Technical Summary

Problems solved by technology

It is directly discharged into the river through the rainwater pipe, causing a certain degree of pollution to the water environment. Therefore, during the recycling of rainwater resources, it is very easy to be polluted by the initial rainwater, which will easily cause pollution and corrosion to the rainwater recycling system during the recycling of rainwater resources. Thus seriously affecting the reliability of rainwater resource recycling
