1. The discharge of wastewater from factories and other industries exceeds the standard

Some factories, such as electroplating and chemical enterprises, did not conduct testing or wastewater treatment when discharging wastewater, and did not even know whether the discharge exceeded the standard; some enterprises secretly discharged industrial wastewater in order to avoid high testing and processing fees, resulting in a large number of The water bodies of rivers, lakes and seas are seriously polluted.

2. Environmental issues of rivers, lakes and seas

In a sense, rivers, lakes and seas can be regarded as a complete ecosystem. The discharge of domestic wastewater in the water system and the inflow of soil containing organic fertilizers will destroy the original ecosystem and lead to uncontrolled reproduction of aquatic plants, etc. problems, such as the 2007 Taihu algal bloom.

3. Education and scientific research

In education and scientific research systems, especially in biological and chemical laboratories, various components and pH values in aqueous solutions will affect the results of experiments, and a large number of testing tools are required to test the experimental environment.

In addition, due to the particularity of the laboratory, the wastewater discharge of the laboratory has the characteristics of material diversity and toxicity, and requires multiple indicators to be tested before it can be discharged.

4. Civil and commercial use

As the saying goes "Water is the source of life", it can be seen how important water plays in human daily life, but in real life, the actual situation of drinking water is not optimistic, especially the excess of indicators such as residual chlorine in tap water , Long-term harm to the happiness of millions of families.

In addition, in commercial aquaculture and other industries, with the rise of smart farming and smart agriculture, farming visualization has become more and more common.

In view of the above-mentioned situation that continues to lead to aggravation of water pollution, the country reiterated during the two major national conferences of this year (2019) to strengthen the treatment of water pollution and support for environmental protection. Liaoning, Jiangxi, Zhejiang, Anhui and other provinces have also successively issued local laws and regulations to maintain the water quality of rivers and lakes, domestic water, industrial wastewater and other fields.

At present, the methods of water pollution detection are mainly water sampling and laboratory analysis, which is not only time-consuming but also unable to keep abreast of changes in the water environment. Often the water environment has deteriorated before testing is carried out. At this time, the quality of water and the impact on people damage to life and property.

Therefore, it is an irreversible trend in the future to monitor water changes in real time online at any time, and the water quality sensor is such a device that can realize online monitoring.

(Ⅱ) System composition

The water quality testing and monitoring system consists of three parts:

① Sensor

Sensors include pH, dissolved oxygen, residual chlorine, ORP, ammonia nitrogen, etc. These independent sensors transmit the measured and accurate data to the data acquisition equipment.

PH sensor—ME2-WB01

PH sensor—ME2-WB01

② Data acquisition equipment

The device is equipped with a variety of data interfaces, 8-channel or 16-channel digital sensor interfaces can be selected, and an industrial-grade low-power high-performance embedded processor is used. Users can set the upper and lower limits of sensor alarms by themselves, and can also realize remote monitoring, management and other functions.

③ On-site display

In order to facilitate users to understand the status of the water body in real time, the on-site LED display screen allows people to understand the current water quality situation, which is conducive to the supervision of regulatory authorities and the supervision of the public, and is conducive to improving the service quality of enterprises and other related water quality supply departments and the public's concern for the environment. awareness of protection. the

④ Central data monitoring center

Centralize all information and transmit it to the monitoring center through the network to realize remote real-time monitoring of water bodies.

(Ⅲ) Ancillary products

Weisheng Technology has now based on the current situation, continuously innovated, carried out in-depth research on the field of water quality detection, and developed a series of water quality sensor products, to respond to the call of the times and contribute to the field of water quality.
