1.project information

This technology identifies and tests the dangerous characteristics of solid waste in accordance with relevant national standards and specifications, and then determines its dangerous attributes or provides a basis for determination. Hazardous waste refers to one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity and infectivity that are listed in the national hazardous waste list or identified according to the national hazardous waste identification standards and identification methods, and do not exclude Solid waste with the above hazardous characteristics. According to the "General Rules for Identification Standards for Hazardous Wastes", the identification procedures for the hazardous characteristics of solid waste in my country are as follows:

The first thing to do is to determine whether the waste to be identified belongs to solid waste. Secondly, only when the waste to be identified meets the category of solid waste can the "National Hazardous Waste List" be further used to judge whether it belongs to hazardous waste. Thirdly, if the waste is not included in the National Hazardous Waste List, it will be judged according to the hazardous waste identification standards. Finally, if the waste does not meet the above conditions, but when it is improperly transported, stored, processed and disposed of, which may have harmful effects on human health or the ecological environment, the administrative department of the State Council may organize experts to determine whether the waste is hazardous. waste.

This technology covers solid waste attribute determination methods, sampling and sample preparation methods, and hazardous characteristic identification and testing methods. This achievement is based in Shanghai in application, radiates to the Yangtze River Delta, and gradually extends to Anhui, Hubei, Shaanxi, Ningxia, Inner Mongolia and Xinjiang. and other regions. The business covers industries covering more than a dozen industries including chemical, pharmaceutical, semiconductor, electronics, smelting, and petrochemicals. A total of more than 100 domestic and foreign companies have provided hazard identification and testing services for solid waste, providing a basis for enterprises to correctly handle solid waste, reducing the amount of hazardous waste generated, and reducing waste treatment costs. He has provided technical services in waste treatment and disposal to many listed companies in the petrochemical and biomedicine industries, realizing comprehensive utilization of waste and turning waste into treasure, which not only reduces corporate costs, but also brings direct economic benefits. He has been invited to participate in the investigation, evidence collection and identification of many cases of illegal dumping and transfer of hazardous waste, providing technical support for the law enforcement and handling of relevant government departments. For example, the much-watched "Tengger Desert Pollution" incident and sudden solid waste pollution cases in the Yangtze River Delta and other places, many of which were supervised by the Ministry of Public Security and the Provincial Department. Led the team to provide scientific and rapid testing services, which was recognized by the enterprises and government departments involved. It not only helps enterprises handle pollutants in a timely and reasonable manner, but also provides a basis for government departments to enforce and deal with them.
