The State Council recently reported that the Provincial People's Government with outstanding achievements in emission reduction work in the “Eleventh Five-Year Plan†and Shandong Province ranked first in the eight provincial governments that have been praised. During the "11th Five-Year Plan" period, Shandong Province's chemical oxygen demand (COD) and sulfur dioxide emissions were reduced by 19.44% and 23.22%, respectively, and they completed 130% and 116% of the country's "Eleventh Five-Year" emission reduction tasks respectively. As the largest chemical province, the chemical industry has undoubtedly made a great contribution to Shandong's energy-saving emission reduction.
I:Boring machine is the machine tool that uses boring tool to bore holes on workpiece, usually, boring tool revolves mainly to move. The movement of boring tool or workpiece is feed motion. Its machining precision and surface quality are higher than drilling machine. Boring machine is the main equipment for machining large box parts.

In recent years, the chemical industry of Shandong Province has guided enterprises to adopt energy-saving and emission-reduction technologies and transform backward production processes to achieve significant results. According to the person in charge of the Shandong Chemical Industry Association, chemical companies that focus on controlling the production of 10 products such as synthetic ammonia, caustic soda, soda ash, and tires have become an important means for Shandong Province to promote energy conservation, emission reduction, and environmental protection, and to transfer methods and adjust structures.
The centralized chemical waste gas incineration project of Zibo East Chemical Industry Zone was put into operation at the thermal power plant of Zibo Thermoelectricity Group. This model of collecting waste gas from chemical companies for unified incineration treatment was the first of its kind in Zibo, and it has also greatly promoted demonstration effects in similar aggregation areas of chemical companies across the country. This project collects waste gas from 4 chemical companies including Shandong Xinhua Pharmaceutical Co., Ltd., Zibo Development Zone pharmaceutical chemical plant, Lanxing Dongda Chemical Co., Ltd. propylene oxide plant, and Zibo Jinma Chemical Co., Ltd. in the Zibo East Chemical Industry Zone. Up, and then laying pipes to the Zibo Thermal Power Group not only effectively handled the chemical exhaust gas, but also saved equipment investment and operating costs for chemical companies. According to calculations, after the project is operational, the amount of pollutants discharged from the eastern chemical zone of Zibo will be reduced by 1.8 tons per year. Compared with the separate burning of chemical plants, the annual savings of natural gas will be nearly 24 million cubic meters, equivalent to approximately 21,100 tons of standard coal, and energy-saving effect. Significant. The project can reduce the emission of chemical waste gas by about 800 million cubic meters per year, which has been plagued by years of chemical odors that have plagued the eastern chemical district of Zibo.
Shandong Lubei Enterprise Group Corporation is the first batch of circular economy pilot units in the country, forming one of the few six recycling economy industrial chains with years of successful operation experience in the country. The six circular economic industrial chains are: ammonium phosphate, sulfuric acid, and cement production recycling economy industrial chain; seawater “one-water multi-use†circular economy industrial chain; clean power generation and salt, alkali cogeneration circular economy industrial chain; ecological electricity industry Chain; oil and coal salt "three in one" industrial chain and titanium dioxide clean production industry chain.
Since the “Eleventh Five-Year Plan†period, Shandong Binhua Group has followed the concept of “Circular Economy, Energy Saving and Emission Reduction, and Green Chemical Industryâ€, and has established a recycling economy industrial park in accordance with the theory of reduction, reuse, and resource recycling. Currently, it has formed a chemical industry. As the main body, various types of resources are used efficiently in the recycling economy industry chain.
Through implementation of the “governance, use, and security†comprehensive pollution control strategy in the river basin, the construction of constructed wetlands has been vigorously promoted, and pollutants entering the river have been reduced in depth. The water environmental quality in Shandong Province has been continuously improved. Jining Chemical Industrial Park is the best example. As an innovative green ecological demonstration zone for the modernization of China's coal chemical industry, the environmental protection goal of the zone is “zero pollutionâ€. Through planning and construction of artificial wetlands and other measures, the park can completely realize zero discharge of wastewater. After the wastewater has completed the "Wetland Tour", the water quality is still cleaner than the water of the North Daliuhe water source, which can not only be discharged directly but also used as industrial water for recycling.
The reporter learned that by the end of 2010, the average concentration of COD in key rivers in Shandong Province had reached 29.6 mg/l, and the water environment quality had recovered to the level before 1985 as a whole, and the province’s control of 59 key polluted river fish had all resumed growth. In the assessment of pollution control in key river basins throughout the country, the “five consecutive championships†for pollution control assessment in the Huaihe River Basin and “three consecutive championships†for pollution control assessment in the Haihe River Basin were implemented.
