This project has established an identification system for the hazardous characteristics of solid waste. Study the rapid identification technology of the hazardous characteristics of solid waste in sudden environmental pollution incidents; study the rapid qualitative screening technology of organic and inorganic substances in solid waste, and establish a qualitative screening data information base based on fixed attributes such as compound retention time, relative molecular mass and ultraviolet infrared excitation wavelength; Study the quantitative detection technology of solid waste, and determine quantitative detection indicators based on qualitative screening results, raw materials, excipients and processes; Study solid waste resource utilization technologies to provide guidance for the resource utilization of sludge containing heavy metals, organic matters, etc. The established system shortens the identification cycle, greatly reduces testing costs and identification risks, and provides better and faster technical support for the identification and management of hazardous wastes. Creatively established a identification system for the hazardous characteristics of solid waste, established a qualitative screening technology for the hazardous characteristics of solid waste, covering the testing of hundreds of parameters in six categories of testing items under the GB5085.1-2007-GB5085.6-2007 standard, and established and improved Solid waste hazardous characteristics quantitative detection technology. Identifying the waste to be identified generated by the enterprise as general solid waste saves the enterprise solid waste disposal costs of 6,000 - 8,000 yuan/ton and management costs; identifying solid waste generated by environmental emergencies as hazardous waste, achieving proper management and disposal. The purpose of reducing pollution to soil, water and atmosphere, has significant social benefits.
