Shore based micro water quality monitoring station for surface wate

  The main monitoring object of outdoor small automatic water quality monitoring station (hereinafter referred to as water station) is surface water
Surface water is water that exists on the surface of the earth's crust and is exposed to the atmosphere
It is the general name of rivers, glaciers, lakes and swamps, also known as & ldquo; Land water & rdquo;
It is one of the important sources of water for human life, and it is also the main component of water resources in various countries
According to the bulletin on China's environmental situation released by the Ministry of ecology and environmental protection, China's surface water was generally moderately polluted in 2014, and the eutrophication of lakes (reservoirs) was more prominent
The main factors causing surface water eutrophication are chemical factors such as N, P, organic matter and hn4 - in the water body
Therefore, monitoring the chemical indexes of surface water such as total phosphorus, total nitrogen, ammonia nitrogen and permanganate index has become a necessary task
It is necessary to monitor the parameters (dissolved oxygen, turbidity, electrical conductivity, temperature and pH) at the same time to comprehensively reflect the water environment indexes
In response to the national strategic policies on strengthening environmental protection, maintaining natural ecological balance and promoting the sustainable development of the national economy, the company independently developed and produced a small outdoor water quality automatic monitoring station according to the needs of the market, combined the methods specified in the national standard with advanced computer technology to realize the full automation of the measurement process, which can be widely used in the monitoring of surface water quality such as rivers and lakes
2
2 monitoring principle of outdoor water station the outdoor water station adopts the integrated design principle, including water collection and distribution system, detection unit (five measurement modules of total phosphorus, total nitrogen, permanganate index, ammonia nitrogen and Changgui parameters), quality control unit and auxiliary unit (waste liquid collection, lightning protection, air conditioning, etc
)
The core unit is the detection unit
Total phosphorus, total nitrogen, permanganate index and ammonia nitrogen strictly follow the chemical analysis methods specified in the national standard
Changgui parameter indexes (dissolved oxygen, conductivity, turbidity, temperature and pH) are measured by multi electrode integration
