At present, the raw material medicine industry is undergoing industrial restructuring, transformation and upgrading. The new GMP certification has already eliminated some of the production capacity through upgrading quality standards. Moreover, quite a number of companies, especially large enterprises, are aware of the importance of environmental protection and invest in environmental protection every year. Some raw material companies even use environmentally conscious methods to achieve environmental protection requirements.
Despite this, the pace of progress in pharmaceutical environmental protection seems difficult to keep up with the pace of social requirements. The late pharmaceutical industry expert Mr. Yu Guanwen once said with pain: The pharmaceutical industry owes too much environmental protection and invests too much.
According to the statistics of the environmental protection agencies, the total funds for the supervision and monitoring operations of the four major pollutants of the state-controlled major pollution sources in 2013 were 354 million yuan. It is expected that the relevant pollutant monitoring budget will continue to increase in 2014.
The reason why the standards and rules for the environmental regulations of the pharmaceutical sector are so complicated is that the pharmaceutical industry is one of the key industries with large chemical oxygen demand and large ammonia-nitrogen emissions among various industrial categories. The production of a raw material drug is often a few steps or even more than 10 steps of reaction, the use of several kinds of raw materials, and some even as high as 30-40; raw materials total consumption of more than 10kg/kg products, high more than 200kg/kg products.
It is understood that the Shijiazhuang Group has invested more than 500 million in environmental protection. It has launched 386 clean production projects and 196 energy-saving projects. It has annual electricity savings of 40 million kWh and reduced COD emissions by more than 2,000 tons. Federal Pharmaceuticals has invested more than 300 million yuan in environmental protection, and now it has a complete environmental protection system including a comprehensive equipment control system, a CASS (biological oxygen demand) pond, and an ammonia nitrogen treatment system.
Today's pharmaceutical environmental issues should rise to an industrial strategic height. With the improvement of pharmaceutical production standards, more products will go abroad, and environmental protection will also become an important promoter of eliminating backward production capacity and industrial upgrading in the future.
Galvanized steel strip is the cold rolled or hot rolled, long and narrow strip of steel with different degrees of plating on a layer called (zinc, aluminum) raw materials. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the substrate of hot dip galvanized steel strip and molten bath to form a corrosion-resistant zinc iron alloy layer with compact structure. The alloy layer is integrated with pure zinc layer and strip substrate. Therefore, it has strong corrosion resistance.
The first stage is pickling the whole coil of strip steel to achieve bright and clean surface. The second stage is hot-dip galvanizing or hot-dip galvanizing, and the third stage is the storage of strip steel after galvanizing. Galvanized steel strip has the characteristics of no rust and corrosion resistance for many years. It can not be affected by external adverse environment, and always maintain its own performance and appearance. In the process of using galvanized steel strip, in order to improve its operation efficiency and its own characteristics, we can carry out post-treatment on the finished galvanized steel strip to make its performance more excellent.
