In this regard, on May 19, 2022, Shanghai Environment released a corporate standard - "Technical Standard for Collection and Disposal of Demolition and Disposal of Square Cabin" (hereinafter referred to as "Standard for Disposal of Square Cabin"), which has been successfully filed on the website of the Shanghai Municipal Bureau of Quality Supervision and entered into force. The standard is the first domestic technical standard on the whole process of disposal of square compartments after the closure of the compartments.
It is reported that, in addition to combining the characteristics of the Shanghai epidemic prevention and control, the square cabin disposal standard refinement of the square cabin final disinfection and assessment and acceptance, but also quantitative analysis of the demolition of the content and sequence of requirements, as well as the demolition of the storage, transportation, treatment and disposal of the whole category, the whole process requirements.
Based on the recycling, resource regeneration, safe disposal of technical routes, the standard also scientifically formulated the different types of square cabin demolition of the amount of calculation methods, under the guidance of the principle of health, safety, order, environmental protection, emphasizing the demolition of the square cabin "application of exhaustive use".
For example: for the elimination of identified no potential risk of contamination of toilets, water heaters, beds and other facilities and equipment, it is recommended that direct reuse; can not be directly recycled materials, that is: bricks, concrete blocks, color steel plate and other construction waste, sent to the construction waste treatment plant for the use of resources; for the low-value foam, wood, etc., for recycling; for medical waste waste, special domestic waste, etc., then into the end of the professional facilities for safe incineration and disposal.
Square-cabin disposal standards for square-cabin hospitals "decommissioning" after the treatment and disposal, to truly ensure safety, classification and grading, but also reflects the conservation of resources, low-carbon, green development concept.
Technical team in the systematic analysis of the square cabin design drawings on the basis of in-depth research in the square cabin site, and actively with the sanitation, disease control and other competent departments, as well as the square cabin design, construction units to communicate and consulting, invited a number of sanitation, disease control, construction and other areas of experts to review the standard, more than 10 units of written feedback and hundreds of expert opinion.
After more than 10 days of round-the-clock efforts, and after more than 10 internal discussions and standard review meetings and other approval processes, the May 19th square cabin disposal standards uploaded to the Shanghai Municipal Market Supervision Administration for the record, marking the successful release and implementation of this corporate standard.
In order to cooperate with a large number of square cabin hospitals in Shanghai to close the cabin disposal, in the overall deployment of the City Investment Group, Shanghai Environment in early May to urgently start the task of enterprise standard preparation, set up a standard preparation team based on the Environmental Design Institute.
The sudden outbreak of the epidemic has made the construction of the number of square-cabin hospitals in Shanghai and the situation of relying on facilities very different from Wuhan or other cities. Coupled with the urgent need to restore the site's function as soon as possible, the experienced practices and routine cycles of other cities could not be referenced, and Shanghai had to develop a set of systematic, refined, and scientific disposal standards.
During the preparation process, the technical team conducted extensive research and exchanges with the Wuhan Urban Management Committee, universities and institutes, industry experts, etc., carefully drawing on their experiences and focusing their analysis on the actual situation in Shanghai. The team also referred to the national joint prevention and control mechanism documents, standards and norms on the square cabin. In the end, the square compartment disposal standard takes into account the whole operation process and management requirements from the closure of the square compartment to the restoration of its function, and extends the scope of application of the standard to the final disinfection and assessment, and environmental monitoring on the basis of the original collection and disposal of this professional field.
The technical team found that, due to the variety of types of square pods, in addition to common furniture and appliances and other configurations, other differentiated facilities and equipment configurations also bring about differentiated needs for decontamination and recycling. Therefore, the disposal standard for square pods proposes that for sensitive places such as schools and business buildings, hydrogen peroxide disinfection products that have no effect on human beings and leave no residue on the environment should be selected, and for square pods with precise and valuable instruments and equipment, the protection of the instruments and equipment will be strengthened before the overall decontamination and specialized decontamination links will be added in the follow-up.
In addition, in order to avoid the operation process of dismantling the disorganized storage, personnel intensive risk, time efficiency lag and other issues, this standard also puts forward the classification of sub-division of the time of the logical main line, strengthening the entire operation process and the application of technology of science.
Shanghai Environment said, the next step, will be in the unified deployment of the City Investment Group, to urgently promote the preparation and approval of group standards, local standards. Through the development of a series of standards, will provide a technical basis for the dismantling, extermination and resource utilization of Shanghai square cabin hospitals, to promote the square cabin hospitals "decommissioning" after recycling, safe disposal, and provide technical support for the restoration of normal order in Shanghai as soon as possible
