According to the relevant provisions of the Law of People's Republic of China (PRC) on the Prevention and Control of Environmental Pollution by Solid Waste, solid waste (including liquid waste) under any of the following circumstances is listed in the national hazardous waste list:
1. has one or more dangerous characteristics, such as corrosiveness, toxicity, flammability, reactivity or infectivity;
2. It is not excluded that it is dangerous and may have harmful effects on the environment or human health, and it needs to be managed according to hazardous waste.
3. Medical waste belongs to hazardous waste. The classification of medical waste shall be carried out in accordance with the Catalogue of Medical Waste Classification.
4. Chemicals listed in the Catalogue of Hazardous Chemicals are hazardous wastes after being abandoned.
5. Hazardous wastes listed in the Catalogue of Hazardous Waste Exemption Management in the appendix of this catalogue may be exempted from management according to the provisions of the exemption content when the listed exemption links meet the corresponding exemption conditions.
6. The mixing of hazardous wastes with other solid wastes and the determination of the nature of wastes after hazardous waste treatment shall be conducted in accordance with the national standards for the identification of hazardous wastes.
Because the domestic sewage is mainly domestic sewage, the total phosphorus and total nitrogen will be higher than the normal value, but the above situation has not appeared.
For example, the sludge from Guangzhou domestic sewage treatment plant has been clearly identified as one of the municipal solid wastes, which can be treated in a general way instead of being classified as hazardous waste.
Extended data
According to the definition of National Hazardous Waste List, hazardous wastes are:
Solid waste (including liquid waste) under any of the following circumstances is included in this catalogue:
(1) Having one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity;
(2) It is not excluded that it is dangerous and may have harmful effects on the environment or human health, and it needs to be managed according to hazardous waste.
It is difficult to count the quantity of this kind of hazardous waste transboundary movement, but it is obviously increasing. Greenpeace's investigation report shows that developed countries are transferring hazardous wastes to developing countries at an annual scale of 50 million tons. From 1986 to 1992, developed countries transferred1630,000 tons of hazardous waste to developing countries and eastern European countries. The transboundary movement of hazardous wastes is harmful to developing countries and even the global environment. First of all, because the importing countries basically lack the technical means and economic ability to treat and dispose of hazardous wastes, the import of hazardous wastes will inevitably lead to damage to the local ecological environment and people's health.
Secondly, the spread of hazardous waste to underdeveloped areas is actually to evade the disposal responsibility stipulated by China, so that hazardous waste will spread to the environment without proper treatment and disposal, and long-term accumulation will inevitably cause harm to the global environment. The harm of transboundary movement of hazardous wastes lies in that these wastes are imported under the guise of trade, and importers have not been properly treated and disposed of in order to obtain economic benefits, regardless of the possible impact on the environment and human health.
The transboundary movement of hazardous wastes has become one of the serious global environmental problems. If no measures are taken to control it, it will certainly cause serious harm to the global environment. 1989 In March, under the auspices of the United Nations Environment Programme (UNEP), the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal was adopted in Basel, Switzerland. The Convention entered into force on May 1992. China is a signatory to this treaty.
