Changed, this will produce substantial amounts of waste and old inactivation denitrating catalyst.Processing to waste and old inactivation denitrating catalyst will face
Serious test.Chinese Ministry of Environmental Protection is issued on soliciting《Notice on strengthening waste flue gas denitration catalyst supervision（Consult on
Original text）》With《Waste flue gas denitration catalyst hazardous waste experience licensing guidelines for examination（Exposure draft）》In explicitly point out：To enter
One step strengthens the supervision to waste flue gas denitration catalyst, prevents it from being caused harm to health and ecological environment, and spy is received
Enter hazardous waste to be managed, encourage waste flue gas denitration catalyst preferentially to be regenerated, help flue gas to take off by fee system
Denox catalyst using disposing enterprise development, improve as early as possible waste flue gas denitration catalyst regeneration, using and disposing capacity, can not be again
Raw and unserviceable waste flue gas denitration catalyst should transfer to hazardous waste landfill to carry out processing disposal.At present, China's denitration
Catalyst regeneration be in the stage at the early-stage, for it is waste and old inactivation denitrating catalyst cleaning technique research be denitrating catalyst again
Raw necessary problem.
