At the beginning of the year, the Chemical Plant issued the Regulations on Environmental Protection Management, which clearly defined the environmental responsibility of personnel at all levels, the reporting procedures of pollution accidents, the comprehensive management of three wastes, the management of civilized factory areas, environmental monitoring and index control, and effectively achieved "whoever pollutes is responsible and whoever pollutes is treated", which effectively mobilized the enthusiasm of all staff to attach importance to environmental protection, participate in environmental protection and rectify environmental protection. In terms of the operation of environmental protection facilities, each system should do a good job of equipment filing, dismantle or suspend the equipment with unqualified environmental protection indicators, and plan to stop the environmental protection facilities that are put into operation and conduct regular maintenance to ensure that all kinds of tail gas are discharged according to standards. In the process of project construction, the factory strictly follows the "three simultaneities" system, based on the transformation and upgrading of the old system and the construction and commissioning of new projects, refines and decomposes environmental protection indicators, and strives to achieve economic, social and environmental benefits. Since last year, the plant has successively completed the "trinity" transformation of the tower-tank-device in the dry absorption system of sulfuric acid, the transformation of the heat exchanger protected by sulfuric acid anode and the dry absorption process, and the transformation of the sodium sulfite evaporation process, so that the sulfur dioxide flue gas is absorbed more fully and the tail gas emission is greatly reduced. At present, the new 53,-ton sulfuric acid system under construction adopts a number of new technologies and equipment with independent intellectual property rights. After the project is completed and put into production, it will realize stable, efficient and automatic continuous production, creating an environmental protection "bright spot" in the company's sulfuric acid production history. In addition, the chemical plant actively cooperates with universities to study the treatment problem of low-concentration sulfur dioxide, and another sulfuric acid system with a scale of 7, tons has also begun to be designed. At that time, the smelting flue gas will be fundamentally treated.
< Positive > Nanjing Jinling Chemical Plant, a subsidiary of Nanjing Chemical Industry Corporation, is a designated manufacturer of chemical plastic stabilizers and chemical raw materials for electronic industry. The enterprise covers an area of 43, square meters and has more than 7 registered employees. The total assets of the enterprise are 75 million yuan and the annual production capacity is more than 2, tons. The products are registered with the trademark of "Lion", and the main products are organized and produced by advanced standards of similar products abroad, which are high-quality products of the Ministry of Chemical Industry, Jiangsu Province and Nanjing City. The output value rate of high-quality products is over 9%. Granular lead oxide and dust-free composite stabilizer are national new products. Dust-free composite stabilizer is an updated product of heat stabilizer in PVC processing, which has good technological performance and good environmental protection function. The enterprise has passed the quality system certification of GB/T19Z-ISO92, with reliable product quality and in-depth environmental protection work. Environmental protection is a great event for the benefit of future generations, and it is also the top priority of this factory over the years. Starting with the rectification of "running, running, dripping, leaking, dirty, chaotic and poor", and turning to relying on scientific and technological progress in recent years, Nanjing Jinling Chemical Plant Co., Ltd. was established in September 23, with its predecessor Nanjing Jinling Chemical Plant as a backbone manufacturer of plastic additives and electronic additives in China, covering an area of 43, square meters. The main products of the enterprise are lead oxide, composite lead salt stabilizer, HA stabilizer, dibasic lead phosphite, tribasic lead sulfate, lead silicate, stearate and other products, with an annual production capacity of 2, tons. The main products are produced by advanced standards of similar products abroad, which are national, provincial and municipal quality products. Since the Eighth Five-Year Plan, the company has always adhered to the fundamental standpoint and starting point of "renovating the site, treating public hazards internally, protecting workers' health, treating pollution, treating public hazards externally, and benefiting future generations" and actively carried out environmental protection work. Taking the environmental treatment with lead pollution as the first priority for the survival of enterprises, the combination of electrostatic dust suppression and WK micropore dust removal technology is used to control lead dust pollution, and the combination of inclined plate sedimentation, micropore infiltration and biochemical technology is used to control lead-containing wastewater, and gradually it turns to relying on scientific and technological progress and adopting clean technology to organize production. From 1991 to 23, with the continuous expansion of the production scale of enterprises, the total annual discharge of lead in wastewater decreased from 962Kg to 15Kg. The enterprise has successively won the titles of "National Advanced Environmental Protection Enterprise", "National Advanced Chemical Environmental Protection Enterprise", national-level "Quality and Benefit Enterprise", "Clean and Civilized Factory" of the Ministry of Chemical Industry, "Standard Enterprise in the Yangtze River Basin", "Civilized Unit in Jiangsu Province" in 21 ~ 22 and "Water-saving Enterprise" in Nanjing, and won the title of "Advanced Environmental Protection Enterprise" for many times. In recent years, the company has stipulated the quality responsibility of environmental protection work in the procedure document of implementing ISO92 standard, so that everything is recorded and checked. The enterprise has also set up a three-level management network of process, quality and environmental protection, and each production section has a set of sewage treatment devices. At the same time, environmental protection management should be included in the assessment of economic responsibility system, and the total industrial pollution discharge should be linked to economic indicators. Make the environmental protection work of enterprises gradually embark on standardized and quantitative management. Since the Eighth Five-Year Plan, Jinling Chemical Industry has been developing rapidly. Enterprises always adhere to the "three simultaneities" and strictly implement the environmental impact assessment and environmental protection approval and acceptance system in new reconstruction and expansion projects. In recent years, the enterprise has invested nearly 4.5 million yuan to control many projects, such as general exhaust, boiler water mill dust removal, lead oxide tail gas, noise in production plant area, sewage outlet and so on, and all of them have passed the standard acceptance organized by the municipal and district environmental protection bureaus. Carrying out cleaner production is an effective way to catch pollution from the source. First, combine technological transformation to realize clean production, and adopt new processes and equipment with high efficiency, low consumption and little pollution. For example, compared with the original powder lead stearate, the flaky lead stearate produced by the new process not only saves energy consumption, but also fundamentally reduces the generation of pollutants (COD, lead, suspended matter and dust). The second is to strengthen management in a targeted manner and reduce pollutant emissions to a minimum through measures such as local transformation. For example, introducing the past direct-discharge wastewater from HA section into boiler room as water for water mill dust collector can save tap water cost by about 15, yuan per year; In 23, the wastewater treated by the general drainage system was recycled as domestic and production water, which saved about 1, yuan of water fee annually. The third-stage drying tail gas directly discharged from the hard salt workshop in the past was introduced into the first-stage dryer through the pipeline, which increased the inlet temperature, not only saved energy, but also reduced dust pollution. While strengthening environmental governance and implementing cleaner production, Jinling Chemical has not forgotten to implement environmental education. In recent years, the enterprise has organized cadres, party member and youth league members in the whole factory to use their spare time and holiday voluntary labor to build a 12-square-meter lawn, transplant more than 5 trees, add more than 6 street lamps and floor lamps to the main roads of the whole factory, and transform the lines and pipe networks of the whole factory; Installed air conditioners for production teams in several sections. The workers' production and working environment has improved, and they are more motivated and more enthusiastic. The production and sales are rising, which has promoted the great development of enterprise economic construction.
