The pollution of the hottest water resources is be

  • Detail

Water pollution is becoming increasingly serious and water quality monitoring is developing rapidly

although China is looking forward to negotiating cooperation with customers in the western region, it has rich resources, but the total population is also large, so China's water resources are actually very scarce. China's per capita water resources are only 1/4 of the world average level and 1/5 of the United States, ranking 121 in the world. China is one of the 13 countries with the poorest per capita water resources in the world. Although China's water resources are so scarce, but now, there is no efficient water resources protection measures to carry out. And in the process of rapid social and economic development, a series of corrosive products also pollute the smooth oil and water pollution

according to the statistics of the Ministry of supervision, water pollution incidents have occurred frequently in China in recent 10 years, with more than 1700 water pollution accidents every year in recent years. In March last year, according to the data released by the Ministry of environmental protection, the residential areas of 250million residents in China are close to key sewage discharge enterprises and trunk roads, and 280million residents use unsafe drinking water. As for groundwater, according to media reports, 90% of the country's groundwater has been polluted to varying degrees, of which 60% are seriously polluted, and only 3% are basically clean urban groundwater. These figures are really frightening

in the face of such a severe water pollution problem, water quality monitoring is naturally the top priority at present. Water quality monitoring can provide a large amount of data and information for environmental management, environmental science research and other fields, and plays a vital role in the whole water environment protection, water pollution control and maintenance of water environment health. For drinking water, only through water quality monitoring can we ensure the safety and health of drinking water. China will avoid bacterial diseases according to the needs of domestic economic and social development; For industrial water, the quality of industrial water can be monitored through water quality monitoring, which is of great significance to prevent industrial water from affecting product quality or damaging containers and pipelines

the development of water quality monitoring industry is closely related to China's economic development. The development process of China's water quality monitoring technology can be roughly divided into four stages: 1970-2000 is the construction period of monitoring stations focusing on water quality; The period from 2000 to 2007 was a period of integration of "monitoring and treatment" focusing on pollution source monitoring; From 2007 to 2010, the water quality monitoring was comprehensively promoted; From 2010 to now, the construction of intelligent environment and third-party governance have been fully started. Looking at the development of China's water quality monitoring, it can be roughly seen that China has initially established a continuous automatic environmental monitoring management and technology system with Chinese characteristics, and has gradually formed a network. At present, China's water quality monitoring technology is developing in an intelligent and diversified direction

as an important branch in the field of environmental monitoring equipment in China, the market scale of water quality monitoring has always occupied more than 45% of the market share of environmental monitoring in China. Compared with atmospheric monitoring, water quality monitoring technology is more difficult and has more monitoring indicators. However, with the continuous development of science and technology, the rapid rise of IOT has driven the technological innovation of the traditional water quality monitoring industry. Various high-tech products that help water quality detection have come out one after another, opening the era revolution of the water quality monitoring industry

after years of research and development, the R & D personnel have successfully developed an intelligent automatic water quality monitoring system based on IOT technology. The system can conduct real-time monitoring of the water environment through automatic patrol robots, and overcome the bottleneck problems of the automatic water quality monitoring system, such as poor scalability of monitoring parameters, lack of quality control means, and insufficient intelligent identification ability of abnormal data. It can automatically monitor 86 parameters such as temperature, chroma, turbidity and heavy metals, and timely transmit the data to the data processing center. The intelligent water quality automatic monitoring system can also carry out remote data transmission and control through GPRS, which greatly ensures the data quality and traceability, and provides a strong technical support for the realization of multi-range real-time water quality monitoring. At present, the indexes that should be paid special attention to when selecting the pulling machine for testing soft packaging materials are analyzed. This system has been applied in the Yangtze River, Minjiang River, Dongjiang River and other basins as well as the middle route of the South-to-North Water Transfer Project, and has played a role in many major water pollution events

the development and progress of water quality monitoring industry has not only cultivated many enterprises with international competitiveness and independent R & D strength, but also made China occupy a place in the international water quality monitoring market. Looking into the future, the water quality monitoring industry has a promising future, and water quality monitoring enterprises also have a lot of opportunities to work for our country. Here, we also hope that China's water quality monitoring technology can make more new breakthroughs and jointly guard the green waters and green mountains of our country
