How to do a good job in water quality monitoring during the transition phase of ecological environment monitoring?

【Hot attention of the Chemical Machinery Equipment Network ] Water resources are important natural resources.
Although 71% of the earth is covered by water, fresh water resources are quite scarce.
According to statistics, in the available fresh water, alpine glaciers and perennial freezing account for 87%.
my country’s total freshwater resources are 2.
8 trillion cubic meters, and the population is 1.
40005 billion.
The per capita utilization of water resources is not optimistic.
In addition, the residents' economic strength has increased and material needs have been continuously met, which has caused tremendous pressure on the environment, and the problem of water pollution has become increasingly prominent.

 

This year is the first year of the 14th Five-Year Plan and the second year of the implementation of the "Outline of Ecological Environment Monitoring Plan (2020-2035)" (hereinafter referred to as the "Outline").
Both regard 2035 as an important time node.
The "Outline" indicates that by 2035, a scientific, independent, and efficient ecological environment monitoring system will be fully completed, and the transition from traditional environmental monitoring to modern ecological environmental monitoring will be fully completed.
The monitoring organization*, planning layout, system specifications, data management and information release are fully unified, and the modernization of ecological environment monitoring capabilities have been comprehensively improved, providing stable restoration of the service functions of the landscape, forest, field, lake and grass ecosystem, achieving a fundamental improvement in environmental quality and the goal of building a beautiful China support.

 

The so-called ecological environment monitoring refers to the monitoring activities carried out for the purpose of accurately, timely and comprehensively reflecting the ecological environment and its changing trends in accordance with the requirements of the landscape, forest, field, lake and grass system view.
It includes monitoring of environmental quality, pollution sources and ecological conditions, etc.
.
As mentioned above, my country's water resources are seriously polluted.
In the context of ecological environment monitoring, it is particularly important to monitor water quality.
So what should we do?
 

　　Only by knowing what is happening can we know why.
Since we are going to talk about how to do it, we must first clarify what it is.
Water quality monitoring refers to the process of monitoring and determining the types of pollutants in water bodies, the concentration and changing trends of various pollutants, and evaluating water quality conditions.
In this process, chemical methods, ion chromatography, atomic absorption spectrophotometry, electrochemical methods, ion selective electrode methods, gas chromatography, plasma emission spectroscopy (ICP-AES) methods are usually used.

 

　　Taking atomic absorption spectrophotometry as an example, it refers to the atomic absorption spectrophotometer to determine the degree of weakening of the radiant light intensity through a predetermined procedure with the metal elements and some non-metal elements in the atomic state as the monitoring object, and obtain the test product The content of the element to be measured in the test element, thus reflecting the overall situation of the element to be measured.

 

　　In addition, many water quality monitoring instruments have also been introduced on the market, such as online water quality monitors, multi-parameter ultraviolet absorption water quality monitors, industrial online multi-parameter water quality analyzers, remote monitoring quality control instruments, water quality monitors, online multi-parameter water quality monitoring Instrument, river water quality monitoring equipment, etc.
This type of equipment has the characteristics of fast monitoring speed and high efficiency, which can effectively assist the water quality monitoring work.

 

　　Water is an important foundation for human production and life, and the prevention and control of water pollution should be placed in a prominent position.
In our pursuit of having both gold and silver mountains and green waters and mountains, we should respond to the call and join the prevention and control team.
I believe that with the guidance of the above-mentioned documents and methods and the addition of instruments, my country's water quality monitoring will embark on a new journey.
