Green chemical environmental protection technology analysis

With the development of China’s social economy, China’s chemical industry scale has gradually increased, but the overall level of development is still not high. The contradiction between industrial development and the environment has become increasingly prominent. With the concept of sustainable development, the realization of the economy The harmonization between development and the environment is an important part of the current situation. Therefore, green environmental protection technologies emerge as the times require, and are increasingly used widely. Green chemical products are becoming more and more common, which shows that the application prospects of green chemical environmental protection technologies are very broad. .

1 Meaning of Green Chemical Environmental Protection Technology

Green chemical environmental protection technology is based on environmentally friendly chemistry, environmentally sound chemistry, and clean chemistry. It is a technical means that uses chemical techniques and methods to reduce or eliminate harmful substances. The core of green chemistry is to reduce or eliminate the pollution of industrial production from the source. It is an objective requirement and an inevitable choice for realizing the sustainable development of the chemical industry. It is one of the most effective means to control chemical pollution and achieve zero emission. China is gradually approaching the world's largest chemical consumer market, and traditional high-energy-consuming, high-emission, and low-efficiency chemical production models can no longer meet the requirements of green chemical environmental protection, with low resource utilization and serious environmental pollution. In the 21st century, China’s resources and environment will face even tougher tests. Only by continuously exploring and researching the use of renewable resources and biochemical methods to replace highly polluting products, will fundamentally control the generation of chemical pollution and strengthen green chemicals. The publicity, training and education of environmental protection technologies, and the continuous introduction of green chemical environmental protection technologies by chemical companies, to track the level of environmental pollution in newly invented projects.

2 The use of green chemical environmental protection technology is imperative

2.1 Green Chemical Environmental Protection Technology Is Adapting to the Development of the Times

In recent years, due to the serious environmental pollution caused by the manufacture of chemical products, chemical products have been indispensable in our lives, virtually increasing the degree of chemical pollution. Green chemical environmental protection technology has become an inevitable trend of the times, how to develop Green chemical environmental protection technology is the focus of current research and analysis from three aspects. a) Advanced chemical technologies and methods are used to make materials non-toxic and harmless, so that resources and energy are fully utilized; b) To achieve The purpose of zero discharge of waste is to make raw materials react under non-toxic and harmless conditions so that the atom's utilization of the material is absorbed by the product; c) The last product produced is a truly pollution-free, green product. And no harm to people's health. In the past, because people’s environmental awareness was not strong and chemical production technology was backward, chemical products caused serious damage to the environment and also directly threatened people’s health. Under such circumstances, people’s environmental pollution caused by chemical industry caused Great importance has been attached to the need to promote sustainable and harmonious development of the environment, economy, and society.

2.2 Green Chemical Environmental Technology is an Inevitable Need for Human Survival and Development

In the process of survival and development, human beings need to continuously use and consume resources, and the science of chemistry is the scientific basis in this process. The chemical industry is the cornerstone of human survival and development. With the development of the social economy and the population soaring, the chemistry The contradiction between industry and the environment has become increasingly prominent. Although the chemical industry has provided people with a steady stream of energy and improved people's lives, it has also caused serious damage to energy and the environment. With increasing environmental pollution, lack of energy and waste, people realize that a large part of the pollution comes from products produced by the chemical industry. The introduction of green chemistry technology has brought new hope for humans to solve the problems between the chemical industry and environmental pollution.

3 Discussion on Green Chemical Environmental Protection Technology

The following discusses the environmental protection technologies of green chemicals from three aspects: the selection of environmentally-friendly technical materials for green chemicals, the production of renewable recycling products, the enhancement of waste materials, and the treatment of hazardous chemical substances.

3.1 Analysis of green chemical environmental protection technologies in the selection of green chemical products

In order to control pollution from the source and ensure the greening of chemical products, we must strictly control the selection of materials, choose renewable raw materials instead of highly toxic materials, conduct chemical synthesis methods at ambient temperature and atmospheric pressure, and apply chemical as much as possible. The harm of the synthetic method is minimized, the toxic materials are catalyzed by suitable catalysts to reduce the impurity content in the product, the stability of the catalyst is improved, new catalysts are continuously developed, and the chemical products are also strictly controlled in the design process. Considering the life cycle and recycling, to reduce the energy consumption in the chemical process, the impact on the environment is reduced to a minimum. In addition, if there is no special situation, as far as possible without using additives or additives, use safer chemical products.

3.2 Production of Chemical Technology for Recyclable Green Chemical Products

China is an energy-consuming country, and the amount of natural resources is limited. Therefore, humans need to develop their own wisdom to convert limited natural resources into renewable recycling resources, provide services for humans, and fully consider whether products are used in the production of chemical products. Renewable, recyclable, reworkable, and other properties. For example, adipic acid, which is a nylon raw material, is processed using traditional benzene extraction. Since benzene is a recognized carcinogen, it not only pollutes the environment but also endangers human health, because glucose is used as a raw material and adipic acid can be obtained through enzyme reaction. Hydroquinone and hydroquinone. Removing benzene from a large amount of organic raw materials is a competitive green chemistry goal.

3.3 Strengthen the processing of waste materials and the treatment of harmful chemicals by green chemical technology

The principle of reducing, reusing and recycling green chemical processes is to reduce or eliminate the use and generation of toxic substances, reduce waste emissions, and maximize the conversion of waste into renewable resources. The screening of catalysts, reagents, solvents and reaction conditions is very important. It converts waste materials into animal feeds, industrial chemicals and fuels; uses toxic and harmless solvents and catalysts instead of highly toxic phosgene and hydrocyanic acid to produce organic raw materials and reduce environmental pollution.
