A Multi-parameter Water Quality Vertical Dynamic Data Acquisition Method for Reservoirs

Abstract

The invention discloses a reservoir multi-parameter water quality vertical dynamic data collecting method, and belongs to the filed of water quality monitoring. A control program of a computer terminal is utilized for optimizing the delay and monitoring depth relationship so as to reduce the delay influence caused by a water quality monitoring probe. In the process of putting a step motor in a water quality collecting system, the computer terminal receives and analyzes the change rate of multiple parameters on the vertical section at a measuring point in real time; the sampling frequency is regulated according to the change rate value of reservoir water quality parameters; the step motor is controlled by a single chip microcomputer for controlling the upward pulling action and the downward putting speed of a multi-parameter data collecting module, so that the change trend of various parameters of the water quality at the vertical section is caught. The reservoir multi-parameter water quality vertical dynamic data collecting method provided by the invention has the advantages that collected water quality data is reliable and efficient, and the water quality delamination phenomenon of large-area deep water bodies such as reservoirs can be monitored.

Description

technical field [0001] The invention belongs to the field of water quality monitoring and relates to a multi-parameter water quality vertical dynamic data acquisition method of a reservoir. Background technique [0002] Water source reservoirs are engineering facilities for water storage and water supply, and water quality protection and management are the key nodes to achieve safe water supply. During the operation of the reservoir, the problem of water pollution has become more and more prominent. After the reservoir is built, most of the pollutants formed by rainfall runoff, human activities, atmospheric deposition and biological metabolic deposition in the reservoir will accumulate in the reservoir, affecting the water quality of the water body. Especially in Northeast China, water source reservoirs are large in scale, deep in depth, and run for a long time, and the water quality in the lower layer of the reservoir has deteriorated seriously. Observations have found th...
