Online water quality monitoring device and method

Abstract

The invention relates to an online water quality monitoring device and method. The device comprises an integrated water quality detector which is provided with a water inlet pipe and a water outlet pipe; the water inlet pipe is divided into three branches, namely a municipal water source inlet pipe, a water tank water source inlet pipe and a standard water source inlet pipe; electromagnetic valvesare arranged on the municipal water source inlet pipe, the water tank water source inlet pipe and the standard water source inlet pipe; and the electromagnetic valves on the municipal water source inlet pipe, the water tank water source inlet pipe and the standard water source inlet pipe are electrically connected to a controller through wires. The device and the method are flexible, timely and effective; the turbidity of a water source of a water tank is monitored in real time, and comprehensive water quality parameter detection analysis is started once when turbidity early warning exists; and even if there is no turbidity early warning, comprehensive water quality parameter detection can be carried out periodically. The controller provided by the invention regularly performs online calibration on a water quality detection instrument, so that the accuracy and reliability of data acquisition, comparative analysis and early warning alarm are ensured.

Description

technical field [0001] The invention relates to a monitoring device and a monitoring method, in particular to a water quality online monitoring device and a monitoring method with simple structure, easy installation and stable performance. Background technique [0002] In recent years, an important direction for the development of secondary water supply in cities and towns is sanitation and water quality safety assurance. On-line detection, analysis, and early warning of secondary water supply water quality have become an important livelihood project and a huge market demand. At present, most of the instruments used in the market for secondary water supply water quality monitoring follow the scheme of the water plant, and the price is relatively expensive; the detection system only realizes the comparison of a single detection data with the local water quality standards submitted for inspection, and lacks multi-dimensional data analysis and comparison and standard determinati...
