Binzhou: Circular economy promotes green development

The party’s report stated that it is necessary to vigorously promote the construction of an ecological civilization and focus on promoting green development, recycling development, and low-carbon development to form a spatial structure, an industrial structure, a production method, and a lifestyle that conserve resources and protect the environment. Bincheng District and Zouping County follow this requirement, optimize the industrial chain with the concept of circular economy, actively save energy and reduce consumption, and effectively promote green development.

Bincheng District: The development of circular economy to promote the transfer of development as a city area, especially in the case of the existing large industrial economy, how to find the balance between industrial economic development and ecological environmental protection is a major issue facing Bincheng District. Since the beginning of this year, the district has vigorously eliminated backward production capacity, supported the development of circular economy, and actively solved problems.

Angel Yeast (Binzhou) Co., Ltd. is a national leader in yeast production. The high concentration of organic wastewater produced during the yeast fermentation process has affected the development of the company because of its high COD content. The person in charge of the company told the reporter that the company alone would have to pay 7.2 million yuan in treatment costs every year for wastewater treatment. To this end, Bincheng District for enterprises to fight for more than 400 million yuan of state technical reform grant funds to help companies invest more than 50 million yuan to introduce advanced yeast wastewater evaporation and enrichment equipment, implementation of a million tons of yeast cleaner production demonstration projects. Jia Ruishan, director of Angel Yeast (Binzhou) Co., Ltd., said: "This set is our evaporative enrichment system. This set of evaporative enrichment system recovers the yeast broth that we originally discharged as waste water. The device is evaporated and evaporated. After evaporating and condensing the finished fermentation broth, our first one is used as a humic acid water-soluble fertilizer, and the Other one we can use as a cement grinding aid, water reducing agent material through the construction of this project. We have realized resource conservation and recycling of waste water, turning waste into treasure.” Through the implementation of this project, we have extended the industrial chain and brought considerable economic benefits to the company. The company expects to increase the output value by RMB 69.20 million and the profit by 1000. Millions of yuan, profits and taxes more than 800 million, the company's wastewater treatment costs have also been reduced by 70%.

Another company in the Bincheng District that develops circular economy - Taiyu Maiye Co., Ltd. is also looking for breakthrough points in perfecting the industrial chain. This company introduced world-class swirling process, five-tower differential distillation technology, and DCS distributed control technology equipment. The organic waste water from deep processing of wheat was extracted using a special filter press and drying technology to extract high-protein feed and then extracted. The sewage after the protein feed is further processed, and the organic fertilizer sludge generated is all returned to the high quality wheat base and the sewage is processed to generate the biogas, and then converted into the production steam through the biogas boiler for the use of the 100,000 tons deep processing project. Only the biogas is used. Using this one year can save the company 15,000 tons of coal. Zhang Zhiqiang, deputy general manager of Binzhou Taiyu Maiye Co., Ltd., said: “We are working hard to build the only wheat breeding company in the country, which is based on wheat breeding, base planting, purchasing, storage, primary processing, food processing, deep processing, and comprehensive utilization of waste. A complete and modernized circular agricultural economic and industrial chain. “At present, Bincheng District has cultivated a large number of high-quality wheat recycling industry chain of Taiyu Maiye, Anqi Yeast Cycle Industry Chain, Shanshui Cement Cycle Industry Chain, and Dongrui Chemical's chlor-alkali chemical industry chain. The recycling industry chain has promoted continuous improvement of the ecological environment in the region.

Zouping: Biomass power generation strung up the green industrial chain Bincheng District promoted energy conservation through the improvement of the traditional industrial chain, and Zouping County took a large part in the links between emerging industries and traditional industries.

Guohong Zhao, manager of the Kaitai Group biomass thermal power plant, said in an interview with reporters: “After our test, two tons of straw is equivalent to one ton of standard coal. During the combustion process, our boilers have also made some adjustments, and the volume of boilers has increased. It is twice as big as the boiler for burning coal, that is, the combustion area of ​​the furnace is twice as large, because the volume of biomass straw is relatively loose and relatively large. “Using straw to generate electricity, this power plant can save 80,000 yuan each year. Tons of coal burning capacity can reduce the emission of oxidized* emissions by 136 tons per year and reduce the dust emissions by 337 tons. The straw ash produced by burning straw can also be used as agricultural fertilizer to return to the field for recycling. Once again, turning waste into treasure will realize the recycling of resources. use. At the same time, a large number of straw purchases have also driven the surrounding farmers to increase their incomes. At present, Kaitai Group is adopting a multi-distribution, market-oriented operation model to support the development of straw storage and storage in the county, and strive to form a complete collection, procurement, processing, and sales network to create a stable straw transformation and utilization industry chain. This year, Zouping County produced about 1.1 million tons of straw annually, and its comprehensive utilization rate reached 93%.
