Under the background of green development, new extraction technology has gradually become an important part of environmental protection industry. These technologies not only improve the efficiency of resource utilization, but also effectively reduce the impact on the environment. However, with the popularization of the application of technology, the industry also faces a series of challenges.

The positive impact of the new extraction technology on environmental protection is mainly reflected in wastewater treatment, soil remediation and resource recovery. For example, supercritical fluid extraction technology is widely used in the removal of organic pollutants in wastewater because of its high efficiency and no pollution. This technology adjusts the pressure and temperature to change the fluid's ability to dissolve, thereby efficiently separating and recovering the target. In addition, ionic liquid extraction technology is excellent in the treatment of refractory organic pollutants, because of its renewable and low volatility, becoming an ideal alternative to traditional organic solvents.

However, the adoption of the technology also faces challenges. The first is cost. The equipment and operating costs of new extraction technologies are usually high, which puts higher requirements on the investment capacity of enterprises. In addition, the complexity of the technology also presents new challenges for the skills and training of operators. The maintenance and troubleshooting of the equipment requires professional technical support, which can increase the operating costs of the enterprise.

Regulatory and standardization issues cannot be ignored. With the continuous emergence of new technologies, the formulation of relevant laws, regulations and standards often lags behind the development of technology. This may lead to compliance problems in the promotion process of new technologies, affecting their wide application.

To overcome these challenges, governments, businesses and research institutions need to work together. The government should increase its support for environmental protection technologies and provide necessary policy and financial support. Enterprises need to focus on technology research and development to improve the cost performance and operability of equipment. At the same time, strengthen the research of technological standardization, ensure that the application of new technologies comply with relevant laws and regulations, and escort the healthy development of the industry.

The new extraction technology has a broad application prospect in the environmental protection industry, but it also needs to face many challenges. Through the joint efforts of all parties, these technologies will provide strong support for the realization of global green development goals.
