This concept has gradually penetrated into various industries, including Chinese medicine pharmaceutical enterprises. In the production of traditional Chinese medicine, various levels of pollutants such as wastewater are easy to occur. If discharged directly into the natural environment without treatment, it will pose a serious threat to the surrounding ecological environment. Relevant workers have been devoting themselves to the treatment of the pollution problem of traditional Chinese medicine pharmacy for many years, actively responding to the national call for green environmental protection, and exploring many ways to improve the production process of traditional Chinese medicine pharmacy, among which membrane technology is an important new and high technology at present and even in the future, and it is a new and high technology that needs to be popularized and applied urgently. The use of membrane technology can effectively solve some pollution problems in production, which is helpful to promote the long-term development of pharmaceutical enterprises towards green and environmental protection.展开更多
