Since the coordinated disposal of solid waste by cement kilns was introduced into China in the 1990s, the promotion and trial use of this new environmental protection technology have been restricted by the unsound solid waste recycling mechanism, the insufficient awareness of the competent authorities on this new technology, and the imperfect process.However, with the strengthening of national environmental protection awareness, the improvement of relevant systems and the increasing pressure on enterprises to transform, a series of factors have ushered in a new development opportunity for the coordinated disposal technology of cement kilns.
At present, China's illegal transfer, dumping and disposal of hazardous waste events frequently reported in the major media, in the event repeatedly banned behind is the lack of solid waste disposal resources, most of the illegal enterprises in order to save costs to maximize the interests of the fluke at the law.At the same time, there are also a part of the enterprise disposal of solid waste hazardous waste is not smooth, it is difficult to find a formal way to receive disposal, resulting in a simply down.With the official commercialization of the cooperative treatment technology of cement kiln launched by jiangsu lvsen, the cooperative treatment of garbage, solid waste and hazardous waste in the process of cement preparation by cement production enterprises will completely solve this problem, providing a avenue for sustainable development of cities and enterprises.
In recent years, the state has issued a series of policies and norms to encourage and promote the construction of cement kilns' coordinated disposal of hazardous waste projects.From the perspective of policy, in 2014, the national development and reform commission and other 7 departments jointly issued the opinions on promoting the collaborative resource treatment of municipal waste and industrial waste in the production process, which clearly put forward the idea of promoting the collaborative treatment of hazardous waste with existing cement kilns.In terms of technical standards, design specifications for collaborative treatment of industrial waste by cement kilns were issued in 2010, and technical specifications for collaborative treatment of solid waste by cement kilns (hj662-2013), pollution control standards for collaborative treatment of solid waste by cement kilns (gb30485-2013), and emission standards for air pollutants in cement industry (gb4915-2013) were issued in 2013.It stipulates the technical requirements for facilities, equipment construction requirements, characteristics requirements for in-kiln waste, operational technical requirements, pollutant emission limits, pollutant control requirements, monitoring and supervision requirements for cement products produced in collaborative disposal of solid waste cement kilns.In December 2016 the cement kiln collaborative disposal of solid waste pollution prevention and control technology policy, actively promote the cement kiln for coordination technology equipment and solid waste pollution prevention and control of the progress of technology, is pay attention to the whole process of pollution control, ensure the environment to effectively control risk, the waste gas, waste water emissions standards, get the safe disposal of hazardous waste;In May 2017, the guidelines for the examination of business license for the coordinated disposal of hazardous waste by cement kilns (trial) was issued. According to the characteristics of the facilities for the coordinated disposal of hazardous waste by cement kilns, the specific examination points for the coordinated disposal of hazardous waste by cement kilns were detailed to standardize the examination and approval of the business license for the coordinated disposal of hazardous waste by cement kilns.
The coordinated disposal technology of solid waste and hazardous waste is a new waste disposal method after incineration and landfill. Compared with the former two technologies, it has obvious advantages of less pollution, environmental protection and strong sustainability.At present, it has been widely concerned by the industry, and can adapt to about 60% types of hazardous waste, with a wide range of applications. It can deal with hazardous waste, household garbage, industrial solid waste, sludge, contaminated soil, etc. The trend of coordinated disposal of solid waste by cement kilns is inevitable, which can be used as an important supplement for solid waste disposal and hazardous waste disposal.
"In the future, the coordinated disposal of solid waste and hazardous waste by cement kilns will be the main business of cement enterprises, while cement production will become a subsidiary industry.The cement enterprises around the city are not only the pollution sources of waste water and gas, but also the main position of absorbing industrial wastes and household wastes.Through transformation and development, cement enterprises can become good neighbors and partners of the city.Luaegis said firmly.
I would like to know more about the introduction of "restricting the coordinated disposal of solid waste in cement kilns has broken the cooperative technology in cement kilns to welcome the spring", and I would like to share with you here, hoping to help you!The collaborative disposal industry of cement kilns develops rapidly. In order to master the collaborative technology level of cement kilns in time, it is necessary to improve the learning ability.
