ZHEZero headspace extractor
Zero headspace extractor is a specialized extraction equipment used for solid leaching toxicity reversal method, which is the environmental protection industry standard of the People's Republic of China for solid wasteLeaching toxicity leaching method sulfuric acid nitric acid method(HJ/T299-2007)Solid waste leaching toxicity leaching method Acetic acid buffer solution method(HJ/T 300-2007)Regulated equipment, United StatesEPAmethod1311Select equipment, when solid waste containing harmful substances is piled up or disposed of, it will leach into water, causing the harmful substances to migrate and transform, polluting the environment. The field or experimental simulation of this natural process in the leaching laboratory. When the amount of harmful substances leached exceeds the threshold set by relevant regulations, the waste has leaching toxicity. The identification of leaching toxicity of solid waste is the basis for determining hazardous waste and an important technical link in the development of solid waste management and treatment technologies.
