——Shandong Dongda Chemical Industry Co., Ltd. is located in Shandong Dongda Chemical Co., Ltd., which is located in Zibo City. It is an old chemical enterprise that has been established for nearly 50 years. The company’s main device—propylene oxide The production line was forced to stop operating. With painstaking experience, the company's decision-makers realized that they must change their business ideas, radically change the extensive economic growth mode at the expense of the environment, and do a solid job of environmental protection and governance. This is the only way out for the company. In recent years, the company has insisted that "environmental protection work is the lifeline of the company's survival and development, not the enterprise's elimination of pollution, or pollution to eliminate the enterprise" business philosophy. The company has experienced three strides in product structure adjustment, environmental protection terminal management, plant area and relocation of production equipment.
The first leap: product structure adjustment Due to the early establishment of the plant and late mergers and other reasons, the company's existing products have the problems of large resource and energy consumption and serious waste pollution. From the 1980s and 1990s, the company began to adjust the product structure, gradually stop production and eliminate some low value-added, resource-intensive, easy to cause pollution to the environment or produce pollution products that are not easy to control, eliminated the bicycle tires, More than a dozen operating environments, such as insurance powder, activated carbon, and benzoic acid, have poor operating environment, high pollution, and high energy consumption. Although the suspension of production of these products has affected some of the company’s economic benefits, the strategic height of social, environmental, and sustainable development The company thinks it is worth it.
So far, the company has invested 48 million yuan in the treatment of wastewater from the main production plant, propylene oxide saponification, and has focused on contaminating salty wastewater. It has been discharging pollutants for three consecutive years, and each year, 10% of wastewater can be reused after being treated. Over the past few years, the company has focused on the development of high value-added, low-pollution products such as medical rubber, polyether polyols, and fluorine-free combination polyethers. These products have accounted for 90% of the company's total products, and they have extended and elongated. Product industry chain to further reduce resource and energy consumption. At present, the company has established an industrial chain of propylene oxide-polyether polyol-polyurethane, optimized its product structure, and enhanced its overall competitiveness.
The second leap: increase investment in environmental protection, strengthen end-of-pipe treatment, and achieve discharge standards for waste. In recent years, Dongda Chemical has carefully implemented measures for rectification and rectification in accordance with the requirements of the Zibo City Government, increased investment in environmental protection, and accelerated the progress of environmental protection and treatment projects. Taking environmental protection management as a top priority for the company, a special project group on governance projects led by chairman Wang Jiwen was established to specifically address the company's environmental governance issues. Most of the large-scale technological transformation projects implemented by the company in recent years are environmental protection projects. These projects include the biochemical treatment of propylene oxide waste water, the concentration and extraction of calcium chloride from propylene oxide wastewater, the wastewater treatment of resin plants, the relocation of resins, and the overall relocation of rubber and plastic companies. And so on, the total investment exceeds 100 million yuan. In the implementation of the project, the company overcomes the difficulties of fund shortage, lack of technical reserves, time-intensive projects, difficulty in high-temperature organization construction, implementation of governance project responsibilities, and the signing of project target responsibility documents, which will be completed within a time limit. The first-phase and second-phase expansion of bio-epoxidation of propylene oxide, the sewage treatment of resin plant, the relocation of anion resin, and the overall relocation of rubber and plastic companies have been put into operation.
In order to promote the healthy and orderly development of the national ion exchange resin industry association industry, as the chairman of the unit, the company and the member units of the association jointly proposed the promotion of cleaner production technology in the industry, explore and promote advanced experience in pollution control, strengthen industry self-discipline, and promote the industry. The sustainable development initiative actively participates in the investigation of the environmental status of industry associations, and explores and studies advanced pollution control experiences. In the transformation of the wastewater treatment plant of the resin plant, the company drew on its successful experience in pollution control and designed and implemented the A/DAT-IAT combined treatment process to treat wastewater from ion exchange resin production. Compared with the traditional treatment method, the investment is reduced by 40%, the operating cost is reduced by 30%, the load impact resistance is strong, the operation is stable, the processing efficiency is high, the operation is convenient, and the management is convenient. The industry association agrees to promote the implementation in the same industry, and is an ion exchange. Resin production wastewater treatment explored a new approach.
The third leap: the implementation of the overall relocation and transformation of some production facilities located in the urban area In order to remove the enterprise from the urban area, the company leaders plan ahead and take into account the changes in the environment and the improvement of the process technology during the relocation of the resin plant. Therefore, on the basis of absorbing and drawing on domestic and foreign technical experience, the company has adopted a more advanced “four-in-one†production process. The device adopts more advanced automatic control technology, and the production scale, device level, and raw material consumption all rank at the leading domestic level. The project also adopts advanced end-of-pipe treatment technologies to ensure that the exhaust gas is discharged through condensation and spray to meet the emission standards, which completely solves the air pollution problem of resin production. Another subsidiary of Dongda Rubber & Plastics Co., Ltd. is located in the center of the city and surrounded by residential areas. In order to thoroughly solve the problems of noise pollution and dust pollution, the company invested 20 million yuan in the overall relocation of the rubber and plastics company to expand and expand the existing machinery and equipment, eliminating the noise, hidden equipment. The new plant is located in Dongda Industrial Park and has doubled the production capacity of medical rubber and plastic parts. The cleanliness of the standardized plant established according to the national medical equipment production plant construction standard has reached 300,000 levels, and the production scale and equipment level are leading the industry. status.
Relying on the future and accelerating development In 2007, Tungda Chemical made a major contribution to energy saving and emission reduction. From the extensive management of the past to the transformation of intensive management, the level of comprehensive utilization of energy-saving and emission-reducing enterprises was significantly improved, and the main production facilities were able to consume energy and energy. The consumption has been greatly reduced, the production cost has dropped by 5% year-on-year, the chemical oxygen demand has dropped by 40% year-on-year, and the chemical “odor†produced during the production process has been gradually investigated. A total of 34 unorganized emission points have been solved, and some point sources have been Closed and centralized processing has received very good results, resulting in a fundamental improvement in the “odor†of the chemical industry, and made due contributions to the “Clear Water Blue Sky†action plan proposed by the Zibo Municipal Government. What is even more gratifying is that this year, the company passed the clean production audit performance assessment organized by the Shandong Provincial Environmental Protection Bureau and obtained a Class B certificate, which has taken a big step towards becoming an environmentally friendly company.
Nowadays, Tungda Chemical has set a higher and further goal. During the "11th Five-Year Plan" period, it will build a new production unit with an annual output of 100,000 tons of propylene oxide and 150,000 tons of polyether. By then, Tungda Chemical’s propylene oxide The annual output will reach 160,000 tons, the polyether will be 250,000 tons, and the annual sales revenue will exceed 5 billion yuan, making it one of the largest chemical new material production bases in Jiangbei of China.
