Abstract: By analyzing the context and the implementation problems of the Technical Specifications for Steam-based Centralized Treatment Engineering on Medical Waste (on trail), the key technical points for standard revision were discussed. Revision suggestions were put forward from process parameters, secondary pollution control and equipment and management aspects, e.g. the steam autoclave treatment process being classified into two categories based on the sequence of breaking and steam treatment; keeping technical parameters of sterilizing temperature and sterilizing time unchanged on the principle of guaranteeing bactericidal effect; optimizing B-D test frequency according to the actual market equipment performance and actual operation management; determining pollutant varieties and loads and recommending pollution treatment process and pollution control measures; adjusting the construction scale limitation and supplementing calculation method of medical waste production amount; removing the compression unit out of the principal project and weakening the description of disposal requirements of treated medical waste.
