Water quality detection and alarm device for river channel

Abstract

The invention relates to a water quality detection and alarm device for a river channel. The water quality detection and alarm device comprises a multi-parameter water quality detector, a processor, a display screen, an alarm device and a water level meter. A fluorescence method dissolved oxygen probe, an optical fiber turbidity probe, a four-electrode conductivity probe, a digital pH probe and an ammonia nitrogen probe are adopted to realize real-time detection of dissolved oxygen, turbidity, conductivity, a pH value and ammonia nitrogen concentration of the river channel. The water level of the river channel is detected in real time by adopting the water level meter. The display screen is connected with the processor and can display the dissolved oxygen, the turbidity, the conductivity, the pH value and the ammonia nitrogen concentration of the river channel detected by the multi-parameter water quality detector and the water level detected by the water level meter in real time; and the detected water quality data is compared with the national standard, and the detected water level is compared with a set warning water level. When the detected water quality and the river channel water level severely exceed the standard, the alarm device can give an alarm.

Description

technical field [0001] This patent relates to a detection device in the field of water conservancy, in particular to a water quality detection and alarm device for river courses. Background technique [0002] China is a typical water-scarce country with extremely scarce fresh water resources. With the growth of population and the development of industry and agriculture, more and more untreated domestic sewage and industrial wastewater are directly discharged into rivers, reservoirs, lakes and oceans, which seriously pollutes China's precious fresh water resources, which in turn leads to water pollution. Resources are more tense, which will eventually restrict the further development of society. River pollution will destroy the balance of the water ecosystem. Pollution will make the water quality worse, the concentration of dissolved oxygen in the water will drop, the turbidity will increase, and the nutrients will be enriched. In the case of severe water pollution, a large...

Problems solved by technology

[0004] Aiming at the deficiencies in the existing technology, this patent provides a water quality detection and alarm device for rivers, which can realize real-time on-line monitoring of water quality, and can monitor the dissolved oxygen, turbidity, conductivity, pH value, ammonia nitrogen concentration and water level of the river. Carry out real-time detection, compare the detected water quality data with the national standard, and compare the detected water level with the set warning water level. When the detected water quality and river water level seriously exceed the standard, the alarm device will give an alarm, so that it can be quickly Solve the problem of water pollution
