Xintai City, Shandong Province vigorously carried out energy conservation and emission reduction, and promoted the transformation of economic growth mode from extensive to intensive, and promoted sustainable economic development.
Clear the indicator system and implement the target responsibility. Since the beginning of this year, Xintai City has established energy conservation and emission reduction organization system, target system and assessment system, and regards energy conservation and emission reduction indicators as one of the important contents of the economic assessment of Xintai Municipal Party Committee and Municipal Government, and clarifies all levels, departments and The company's target responsibility has also signed annual energy-saving target responsibility letters with 60 key energy-using enterprises, and these enterprises are evaluated at the end of the year. Zhengda Coking, which was built with an investment of more than 7 million yuan, uses coal-fired power generation projects with coking and generating electricity. The annual power generation capacity is more than 80 million kWh, which not only overcomes the pollution of gas to the environment, but also increases the profits of enterprises.
Curb the "double high" industry and eliminate backward production capacity. According to relevant state regulations, Xintai City strictly examines, approves and records some high-energy-consumption projects that are newly built, renovated and expanded. In accordance with the law, more than 60 small-scale enterprises in the “10th Five-Year Plan†have been eliminated, and the chemical oxygen demand has been reduced by more than 400 tons, and the sulfur dioxide emissions have been reduced by 150 tons. Eliminate the ordinary shaft kiln cement production line, reduce the output of 1.464 million tons, save 162,000 tons of standard coal, and reduce the sulfur dioxide emissions by 100 tons. The phase-out of small thermal power plants was phased out, and the task of shutting down the 117,000-kilowatt group was completed in three years. This year, it shut down 33,000 kilowatts.
The circular economy model is an important means of sustainable development. Xintai City has identified three parks, and 16 enterprises have conducted pilot projects for circular economy. They have explored the formation of a small internal circulation model, an inter-enterprise circulation model, and a regional social circulation model. Only the large coking gas is transported by pipeline to Zhengda Thermal Power Company for power generation, saving 52,000 tons of standard coal per year. It plans to build two sewage treatment plants, Xintai and Xinwen, which will process 80,000 tons of urban sewage per day and 20,000 tons of recycled water per day. Recently, Xintai has concentrated its efforts on three circular economy projects: first, construction of 2*66 million KW+2*1 million KW ultra-supercritical unit projects, second, construction of dielectric and building materials recycling economy industrial park, and third, planning and construction of coal chemical industry. industrial area.
Overall promotion, comprehensive energy saving. In the construction field, the standards for energy saving of new residential buildings of 65% and new public buildings for 50% were strictly implemented, and various new materials for building energy conservation were actively promoted, clay bricks were completely eliminated, and the production and use ratio of new wall materials was significantly improved. In terms of water resources utilization, all of the city's self-prepared wells were closed, and the city's water use “one household, one table†was fully implemented, and water conservation measures were implemented from the source. In the field of consumer energy conservation, energy-saving lamps, light control, and voice-activated switches are widely used in various types of building facilities. Energy-saving products such as solar energy and water heaters have been popularized in towns and towns above townships, and the use area of ​​biogas and fuel-saving coal stoves in rural areas is expanding. .
Through the implementation of energy conservation and emission reduction, the comprehensive utilization level of Xintai resources has been significantly improved, the water quality of the surface water surface in China has been greatly improved, and the urban air quality rate has reached 95%.
