As clearly required in the “Outline of the Eleventh Five-Year Program for National Economic and Social Development of the People’s Republic of China”, by 2010, the average annual growth of GDP shall be 7.5%, the unit GDP energy consumption shall decrease by 20%, the major pollutants shall decrease by 10%, which shall be completed as the binding force targets during the “Eleventh Five-Year” period. In 2006 when the “Eleventh Five-Year” started, the discharge of sulfur dioxide in the whole country amounted to 25.944 million tons, the discharge of chemical oxygen demand amounted to 14.313 million tons, and the discharges of the two didn’t fall but rise, with a growth of respectively 1.8% and 1.2% compared to those in 2005, and the emission reduction of the major pollutants became more severe.
China’s economy has grown rapidly, and all the constructions have made great achievements, but at a huge resource and environmental cost, the contradiction between economic development and resource environment has become increasingly acute, and people have strong reaction toward the problem of environmental pollution. This situation is directly related to the unreasonable economic structure and extensive growth mode. If we don’t accelerate to adjust the economic structure and change the growth mode, the resources are not enough, the environment cannot bear, the society cannot stand and the economic development cannot continue. Only by adhering to conservation, clean and security development can we achieve the sound and rapid development of the economy. Meanwhile, the emission of greenhouse gas has caused the global warming, which attracts the attention of the whole world. To further enhance the energy conservation, emission and reduction is an urgent requirement to deal with the change of the global climate.
To complete the binding target of key pollutants reduction and emission, it is an urgent requirement to establish and complete a scientific system of emission reduction targets, accurate monitoring system of emission reduction and strict evaluation system of emission reduction, thus implement the emission reduction work by strict scientific statistics, monitoring and evaluation methods. To build the automatic monitoring system of state-controlled key pollution sources, and to automatically monitor the emission status of pollutants in the national key monitoring enterprises which occupy 65% of the country’s total pollutants load, is an important part of the “Three Systems” in emission reduction construction. The technical means such as automatization and informatization can have a more scientific, accurate, and real-time master of the key pollutant discharge data, operation conditions of pollution abatement facilities and other information related to the pollutant emission in the key pollution sources, timely detect and investigate the illegal pollution discharge behavior. It is an effective means to supervise whether the key pollution sources have completed the emission reduction targets of pollutants.
Project construction content of automatic monitoring system of pollution sources
The automatic monitoring system of pollution sources is composed of automatic monitoring devices and monitoring center. Automatic monitoring devices refer to the on-site instruments, flow meter, recorder of pollution abatement facility operation, and data collection transmitter, etc for monitoring and surveying the pollutant emission. The on-line monitoring equipment is able to monitor the data concentration of pollutants in pollution sources, the flow meter can continuously record the flow rate of pollutants, and the recorder of pollution abatement facility operation can monitor the switch situation of the pollution abatement facilities in real time in the polluting enterprises.
The monitoring center refers to the software and hardware connected to automatic monitoring devices through communication transmission lines by the environmental protection department, which are used to automatically monitor the key pollution sources. The hardware mainly includes the server, the special equipment for receiving data on pollution source end, the display and interactive system, the basic environment for monitoring network, the network security system, etc. The software includes the server operating system and database software (commercially available), the basic database of pollution source, the application system of pollution source monitoring, the data transfer and backup system, and the network security system, etc.

Value of proposal to Environment-friendly clients
By taking advantage of optimized investment, highly cost-effective X86 server and storage plan, Inspur can build data processing system with higher performance, better usability and easy utilization and management for automatic monitoring information platform, reducing investment in management, maintenance and services and guaranteeing investment in system building.
The mainstream design of three-layer architecture is employed. The mainframe system of the server is divided into data layer, application layer and access layer. The security, centralization and real time of data monitored at the pollutions source are fully taken into consideration. According to the principle of uncompromising allocation, server, processing performance of storage, memory and I/O bandwidth are taken into full account, meeting the demand for centralized management of data monitored at pollution source, centralized storage and backup of data and providing a uniform platform expandable and flexible deployment of future projects as the system application layers fully unveil.
The establishment of the platform for data center accomplishes collection and integration of basic data and sharing of transactional information, allowing environmental protection to proceed in a more efficient and reasonable manner and accomplished the following objectives:
