Sewage treatment automation -- forgotten wealth highland

under the new situation of energy conservation and emission reduction, sewage treatment puts forward higher requirements for automatic products. Good quality control enables the products to operate efficiently and stably. In order to ensure the efficient and stable operation of the water plant, the high reliability requirements of sewage treatment on the control system require that PLC support a variety of redundant methods, which can better improve the reliability of the system, improve the operation efficiency of the water plant and sewage plant, and provide a guarantee for more strict water quality standards

the water treatment industry will usher in a large number of development opportunities

operators can work efficiently and permanently in a comfortable and natural posture

during the 12th Five Year Plan period, with the upgrading and reconstruction of sewage treatment plants, the continuous improvement of water treatment and water supply scale, and the improvement of sludge treatment and reclaimed water reuse ratio, the water treatment industry will usher in a large number of development opportunities. In general, it can be reflected in the following four aspects:

first of all, there are a large number of sewage treatment projects that have been built and are under construction. The national requirements for the effluent quality of sewage treatment plants are more stringent, from level 1 B to level 1 a. many existing sewage treatment plants need to be upgraded

are all aimed at the world's largest new energy vehicle market - China

secondly, the annual sewage treatment volume in the 12th Five Year Plan will reach 50012.4 billion cubic meters of polysulfide building sealant. Provincial capitals and prefecture level cities are still the focus of construction. During the 12th Five Year Plan period, there will be a total of 379 cities with construction needs, and the treatment scale of new facilities will be mainly small and medium-sized, but will continue to increase

third, with the continuous increase of urban population, there is also a demand for new construction and expansion of water purification plants in China. At the same time, the standards quoted in the 12th Five Year Plan have also been improved, from 35 standards to 106 standards

finally, according to the requirements of national energy conservation and emission reduction and the development of low-carbon economy, urban sewage treatment will focus on pollutant emission reduction, and sludge treatment and sewage recycling will become a new hot spot in the development of the industry. China's water treatment market will be in a golden growth period for a long time to come. At the same time, the localization of water treatment automation system will also become an inevitable trend of industry development

current situation of sewage treatment automation

the automatic control of sewage treatment in China started relatively late. After entering the 1990s, sewage treatment plants began to introduce automatic control systems, but most of them directly introduced complete sets of automatic control equipment from abroad. Domestic automatic control systems account for 68% of the global output and are rarely used in sewage treatment plants. As early as the 1970s, China's water industry began to apply automation technology. By the 1990s, automation and informatization have been widely valued in the water industry. In the past 20 years, China's water industry has made great progress in the application of automation technology and information technology, creating good economic and social benefits

in the past two decades, automation technology and information technology have been widely used in the water industry. In particular, automation technology is applied to the automation transformation of gate pump stations, SCADA systems of water plants and sewage plants, and urban water supply dispatching systems. With the continuous development and popularization of wireless communication technology, Internet technology and video technology, the visualization of the water industry has been basically realized

however, compared with the international level, China's automation and information technology is still relatively lagging behind, and on the whole, it is still at the level of foreign countries. It is mainly reflected in the unbalanced development and application level. The information technology aiming at intelligent decision-making is relatively slow, the phenomenon of information island is still serious, automation technology and information technology are lack of integration, and a large number of process data are lying quietly on the scene, without playing its due role

demand for sewage automation products

as one of the important tasks of the current development of the water industry, the progress of its work has attracted much attention. Automation and information technology, as the post auxiliary force in the development of the water industry, ensure the continuous progress of energy conservation and emission reduction. It will solve the process control and management intellectualization of production water, water supply, drainage disposal and sewage disposal, so as to minimize the waste of water resources, basically realize the optimal allocation of water resources, and maximize the recycling of water resources

under the new situation, sewage treatment puts forward higher requirements for automatic products. Good quality control enables the products to operate efficiently and stably. In order to ensure the efficient and stable operation of the water plant, the high reliability requirements of sewage treatment on the control system require that PLC support a variety of redundant methods, which can better improve the reliability of the system, improve the operation efficiency of the water plant and sewage plant, and provide a guarantee for more strict water quality standards

in order to reduce the energy and drug consumption of the system, the system is required to have a wealth of control algorithms, such as process control algorithm, fuzzy control and other advanced process control algorithm, frequency conversion regulation control algorithm, etc., which can integrate power management and intelligent control of water pumps. At the same time, it is flexible and open. In terms of the characteristics of water treatment engineering, products from multiple suppliers may be included in a project, and the electronic control system is required to be highly inclusive and comply with IEC international standards

in order to save costs and reduce the workload of system maintenance, the control system is required to be easy to use and maintain. All modules are required to support hot plugging, and the system program can be upgraded and backed up through SD memory card. The backplane is designed with anti mixing pins to avoid inserting wrong modules. The unique wiring terminal design and the pre wiring system are provided. Because automation professionals in the water industry are relatively scarce, and most technicians are mainly engaged in process maintenance, we hope that the automation system is stable and reliable. Even if it fails, it can quickly recover the system with simple operation, so as to minimize the impact on continuous water supply or sewage treatment

automation products are widely used in the water treatment market. In the future, new projects and reconstruction projects will drive the growth of a series of automation product markets such as PLC, frequency converter, various instruments, SCADA, etc. With the continuous improvement of the automation level of the water treatment industry, the industry's demand for automatic monitoring software is growing; At the same time, with the increase of urban projects, the project has relatively low requirements for the system, and because the cost of such small and medium-sized projects is limited, in the future urban projects, the application of small and medium-sized PLC will increase, and the application of local brand frequency converters will increase
