Water Treatment Purpose The importance of water treatment What is the meaning of water treatment?

The importance of water treatment:

The purpose of water treatment is to improve water quality and make it reach a certain water quality standard. According to the different treatment methods, there are physical water treatment, chemical water treatment, biological water treatment, etc. According to different treatment objects or purposes, there are two main categories: water supply treatment and wastewater treatment. Water supply treatment includes two types of drinking water treatment and industrial water treatment; wastewater treatment is divided into domestic sewage treatment and industrial wastewater treatment. Among them, the boiler feedwater treatment, make-up water treatment, steam turbine main condensate treatment and circulating water treatment, which are particularly closely related to thermal technology, belong to the category of industrial water treatment. Water treatment is of great significance for developing industrial production, improving product quality, protecting the human environment, and maintaining ecological balance.

What is the meaning of water treatment?

Water is the source of life and the cradle of human civilization. It breeds and sustains all creatures on the earth. Water, as an indispensable resource, has long been considered inexhaustible and inexhaustible. With the continuous development of human society and industrial modernization, the quality of the water environment is getting worse and worse, and the shortage of water resources is becoming more and more serious. All this has increased the load on the city and brought a series of ecological environments that endanger the survival and development of the city. problem. In addition, with the continuous expansion of the scale of cities, the amount of water and drainage in the city is increasing, which intensifies the shortage of water resources and the pollution of water quality. Water environmental problems are becoming increasingly prominent, which seriously restricts the social and economic development of our country.

Environmental protection is a basic national policy of our country, and sewage treatment is an important measure to protect the urban and rural environment. The country attaches great importance to this. The Ministry of Construction, the State Environmental Protection Administration, and the Ministry of Science and Technology pointed out in the "Urban Sewage Treatment and Pollution Prevention Technology Policy": "The construction of urban sewage treatment facilities should adopt mature and reliable technologies. The effluent of urban sewage facilities should meet the national or local regulations. Pollutant emission control requirements", environmental protection, energy conservation and emission reduction are major measures to implement the scientific development concept and build a harmonious socialist society. They are the inevitable choice for building a resource-saving and environment-friendly society. They are essential for adjusting economic structure and transforming The mode of growth, improving the quality of people’s lives, safeguarding the long-term interests of the Chinese nation, and realizing the Chinese dream are of extremely important and far-reaching significance.

In recent years, although the efficiency of sewage treatment in my country has been continuously improved, the denitrification and phosphorus removal of sewage treatment plants in my country generally have the disadvantages of high energy consumption, low efficiency and unstable operation; in addition. Sewage treatment plants in developed countries have basically realized the automatic testing and process control of the main parameters in the process, while the automatic control of sewage treatment in my country started late. After the 1990s, sewage treatment plants began to introduce automatic control systems and domestic automatic control systems. There are few applications in sewage treatment plants, and there is a big gap between my country and developed countries in terms of operation management and process control. At present, the water and electricity consumption per ton of urban sewage treatment plants in my country is nearly twice that of developed countries, and the number of operation and management personnel is several times that. Most of the established sewage treatment plants are still in manual operation, which greatly reduces urban domestic sewage. Processing efficiency.

The upgrading and transformation of sewage treatment plants must rely on technological progress, and the guarantee and support of new technology and high technology must be provided from beginning to end. Urban sewage treatment technology is the key to the efficient operation of urban sewage treatment facilities. Therefore, to realize the optimization and automatic control of the urban domestic sewage treatment process in our country, and to improve the efficiency of urban domestic sewage treatment to solve the serious water pollution problem in China, there are important theories in terms of saving money and improving the sewage treatment effect in my country at this stage Meaning and practical significance.
