[ Hot Focus on Chemical Machinery and Equipment Network ] China's total freshwater resources are relatively abundant, but per capita water resources are only 1/4 of the world's average level.
It is one of the countries with poor per capita water resources in the world, and our water consumption ranks among the top in the world.
, the contradiction between supply and demand of freshwater resources is more prominent, and problems such as resource water shortage, regional water shortage, seasonal water shortage, and engineering water shortage are obvious

.
In addition, with the development of China's industrial economy and the rapid progress of urbanization, China's water resources are faced with serious problems of water volume decline and water quality deterioration
.
However, disordered exploitation led to frequent reports a few years ago that over-exploitation of groundwater in a certain place resulted in ground collapse and seawater inversion

.
The "mysterious" groundwater is hidden under the soil and penetrates into the rock voids, providing strong support for the soil and rocks
.
The rational exploitation of groundwater is particularly important

We know that there are two ways to obtain groundwater, natural groundwater outcrops and artificial extraction
.
Groundwater can transport water to the outside world through natural drainage methods such as spring water
.
Spring water is a natural outcrop of groundwater, and can often be seen in the valleys and foothills of mountain hills and piedmont areas

Manual mining methods include wellbore extraction, channel and tunnel excavation,
etc.
Among them, the use of wellbore to extract groundwater is the main way of groundwater exploitation and utilization, and it is relatively common in the water supply process of residential life, industrial enterprise production and agricultural irrigation
.
The common large wells and pressure wells in rural areas are the simplest methods of groundwater exploitation
.
For the centralized water supply in cities and towns, groundwater is exploited by means of relatively deep mining wells, which are more complicated in technology, and then transported to water plants through pipelines for proper treatment, and then enters the water transmission and distribution system to achieve water supply

In the process of groundwater exploitation, instruments and meters are everywhere.
From finding water to sampling and testing to mining, instruments and meters are indispensable, such as groundwater detectors , water quality samplers, analyzers, and so on
.
Among them, instruments and meters also play a huge role in the detection of urban sewage

There are many types of urban water pollution, including industrial pollution, agricultural pollution, and domestic pollution caused by natural pollution and human activities.
For different pollution sources, the concentration and change trend of different indicators can be detected to evaluate the water quality, so as to make the water healthier

.
Since the State Council issued the "Ten Water Regulations" in 2015, all localities have made great efforts to control water pollution and strengthen the protection of water resources, and the phenomenon of over-exploitation of water resources has been improved
.
In order to better protect water resources, this year, all localities have designated prohibited and restricted groundwater mining areas, built water quality monitoring stations, etc.
, vigorously publicized the knowledge of water resources protection, and actively responded to the "Ten Water Regulations" and the theme of China Water Week

.
For example, Qingdao has built a total of 57 automatic water quality monitoring stations, 9 online monitoring projects, and established a scientific and effective water ecological environment monitoring network in Qingdao
.
Jinan Water Group invested more than 30 million yuan to build a new water quality center, more than 100 sets of large and medium-sized instruments and equipment, and more than 240 testing items

Jiangsu has made efforts in metering monitoring and monitoring and early warning, clarifying the legal responsibility of groundwater intake users to install metering monitoring, and underground water intake wells in the province are installed with metering facilities as required
.
Completed the national groundwater monitoring project, built a total of 523 water conservancy monitoring wells, and achieved full coverage of automatic monitoring of water level and water temperature at basic groundwater monitoring stations

.
Among them, the automatic water quality monitoring station is an online water quality automatic monitoring system constructed by using modern instrument analysis technology, automatic control technology, computer application technology and communication transmission network.
It has the characteristics of fast response time, high monitoring frequency, large amount of data and high degree of automation

It is everyone's responsibility to cherish water resources, protect the water environment, and prevent and control water pollution
.
As an enterprise in the instrumentation industry for water quality monitoring, it should actively respond to global changes, seize the current major problems in water resources, take advantage of favorable policies, combine corporate development with social responsibility, give full play to its own advantages, and introduce advanced technologies.
Improve the hard power of the enterprise, so as to escort high-quality water resources
