Present status and suggestions on the standard system of ecology and environment of fly ash in China

The existing laws, administrative regulations, department rules and documents, and relevant standards on the management of fly ash in China were introduced systematically. It showed that there was no specific technical standard for environmental pollution prevention and control of fly ash in the current ecological environment standards, and the standards related to general industrial solid waste were applicable in the environmental management of fly ash, with a small number of standards and incomplete coverage. There was also a lack of technical standards for environmental pollution prevention and control in the production, collection and transportation of fly ash, as well as in various comprehensive utilization modes of fly ash, which was not convenient for the comprehensive utilization and pollution prevention and control of fly ash. The current standard system of ecology and environment of fly ash needs to be further improved from the aspects of the whole process management and promotion of comprehensive utilization and pollution prevention, risk prevention and control, information construction, and so on.
