The end of 2002, the Ministry of Construction proposed to promote the market-oriented reform of municipal public sector views. Accelerate the pace of reform in the municipal public sector. Originally as a city water plant welfare will have been launched and has become an important part of urban life, improve the level of modern life.

 

 

By the end of May 2008, the country built and operates 1408 sewage treatment plants, which is not included in the township, factories, and a variety of sewage treatment plant. According to China's water network "of sewage treatment BOT project Market Report", with the gradual implementation of the "Eleventh Five-Year Plan", the county sewage treatment plant construction is also accelerating the pace of the country, so a conservative estimate, as of the end of 2010, China's At least there will be nearly 3,000 sewage treatment plant built and operated.

 

On the one hand better and more economical to build sewage treatment plants, on the other hand, for the long-term interests of the whole nation and the state, in the "Eleventh Five-Year" Plan proposed to reduce the "Eleventh Five-Year" energy consumption per unit of GDP about 20%, the total discharge of major pollutants reduced by 10%. It is also building a resource-saving and environment-friendly society inevitable choice is to promote the adjustment of economic structure, transform the mode of growth the only way.

 

However, such a large number of new sewage plants, will be bound to the total energy saving control target a certain degree of challenge. Faced with this challenge, what kind of panacea for it?

 

He said that the 21st century is the information age, and perhaps open conflict between the total amount of the new sewage plant and the energy saving key is information technology.

 

About sewage treatment plant energy consumption this point, Beijing Tsinghua University Planning and Design Institute WWTP intelligent monitoring system (EICA, Energy-Saving Instrument Control and Automation) control can play an effective role. According to the author's understanding of the software from the daily operations of the water level, depth model simulation and process optimization levels, more remote water control and management level to achieve the current single wastewater treatment plant, sewage treatment plants and even the army of intelligent control.

 

So EICA is how to achieve these three levels to control it? The first is the daily operations of the waterworks. This system is based on the integration of intelligent control equipment sewage plant, and will also include what we call the PLC and other control devices, on the basis of this device, the control software using patented technology can manage the daily operations of the water level and control. Of course, this is just a stop at the level of management and control, energy conservation for our lofty goals also need to help the second and third levels.

 

Then look at the second level, which is the depth of the model simulation and process optimization levels. On the basis of the daily operational management and control, combined with a lot of patents, for example based on the "gas dynamic changes of feedback control theory," intelligent design aeration control system based on the model of the whole process of the entire water control strategy, dynamic pumping station group control and other methods. Using these optimization methods, can be 2 - cost recovery software investment within three years, but also can save a lot of power consumption and unnecessary wear and tear. Truly enhance the entire internal water management.

 

The most interested in a large group of water, or the use of B / S (browser / server) architecture developed by the group control management system. Thus, we can achieve the Group Water Operations Research or defeat, winning in thousands of miles away goal. If there is a strange water, there will be a short message system will automatically send the case to the relevant managers mobile phone, real-time monitoring.

 

In these three levels, EICA is water management a lot of work to increase accuracy, optimize workflow and management. But also for the strategic approach to energy conservation floor provided a guarantee.

 

In addition, in the field of IT industry, combining water and there are many companies in many products, they are for the water industry operators to control all aspects of early warning to provide a guarantee of efficiency words. We also firmly believe that in the near future, the water industry will be more rational use of the IT industry to bring good help promote the industry faster and better development.
