VOCs governance is a big problem, which needs constant innovation and exploration of pharmaceutical enterprises

[industry trends of pharmaceutical Station] previously, two new national standards, GB 37823-2019 emission standard of air pollutants for pharmaceutical industry and GB 37824-2019 emission standard of air pollutants for coating, ink and adhesive industry, jointly issued by the Ministry of ecological environment and the State Administration of market supervision, were implemented on July 1 Among them, GB 37823-2019 emission standard of air pollutants for pharmaceutical industry stipulates the emission and concentration limits, monitoring, supervision and management requirements of air pollutants and odor pollutants for pharmaceutical industry New enterprises shall implement the emission standard of air pollutants from July, while existing enterprises shall implement the emission standard of air pollutants from July 1, 2020 As a heavy pollution industry, the pharmaceutical industry is currently facing a number of high-pressure environmental protection standards and policies, and environmental cleaning will be upgraded again This also poses a higher challenge to pharmaceutical enterprises with serious air pollution VOCs governance is a big problem Different VOCs governance technologies are different, which need enterprises to innovate, explore and verify all kinds of governance technologies to gradually solve According to the industry, VOCs and peculiar smell are the main pollutants discharged by enterprises in the biological fermentation pharmaceutical industry At present, there are few researches on VOCs and peculiar smell pollution characteristics and treatment technologies in this industry in China Many pharmaceutical enterprises have to relocate due to lack of supervision and control and inadequate environmental protection measures In order to conquer it, many pharmaceutical companies have made great efforts and expenses For example, some pharmaceutical enterprises adopt the green production mode of source reduction, whole process control and end treatment According to "source reduction, closed collection, classified treatment and comprehensive reinforcement" According to the four principles, the technical route of "introduction, absorption, digestion, integration and re innovation" is adopted, and then the integrated process technology of "negative pressure closed collection + pretreatment + molecular sieve / activated carbon adsorption concentration + high temperature oxidation combustion" is adopted to systematically treat VOCs, so as to improve the treatment efficiency and reduce the cost There are also pharmaceutical enterprises to speed up the construction of VOCs treatment facilities in tablet workshop in response to the environmental problems caused by pharmaceutical factories, and cooperate with some universities to find out the obvious odor production sources, complete the analysis of problems and develop solutions Currently, they are actively organizing the construction of treatment equipment Experts pointed out that there are several major problems in VOCs waste gas treatment in pharmaceutical industry First of all, most of the domestic pharmaceutical enterprises are mainly small and medium-sized, with limited technology, talents and funds, and the cost of treatment technology is expensive Pharmaceutical enterprises are reluctant to spend money or be afraid of water drift They prefer to choose some relatively simple VOCs waste gas treatment measures to meet the emission requirements Such simple facilities and equipment have general operation effect, which can not guarantee long-term stable operation and capacity Easy to produce environmental pollution Second, there is a lack of specific and targeted exhaust emission standards In the current relevant indicators, the formulation of organic pollutant emission indicators is not perfect, and pharmaceutical enterprises cannot achieve optimal treatment in the process of waste gas pollution control In recent years, with the continuous improvement of relevant emission standards, the governance of pharmaceutical enterprises may be put on the agenda Third, environmental protection supervision is difficult There are many kinds of pharmaceutical and chemical products, and the update speed is fast In the process of production, enterprises generally adopt the way of small batch production Some enterprises even report false information to avoid responsibility, which leads to the failure of relevant environmental protection departments to grasp the real-time information of pollution discharge in time Moreover, the waste gas pollution has a great destructive power to the environment, and the transmission speed is fast, so it is difficult to evaluate it effectively Therefore, the implementation of environmental protection supervision is difficult, and the relevant management system of environmental protection supervision department needs to be improved.
