Technical Field The invention relates to the field of chemistry and environmental science and technology, in particular to a chemical drug harmless treatment device.
Background The poisonous substances and intermediate products were harmful to the environment. Prior conventional treatment methods were mainly incineration and direct landfill. Incineration can effectively destroy harmful components of poisonous substances and reduce waste volume and quality, which is the fastest and most effective method to achieve harmless treatment. But the incineration technology cannot be used to treat hazardous liquid wastes, and the safety is not enough in handling poisonous substances. The incomplete oxidation products will form tiny organic particles suspended in the atmosphere and become a component of air pollution. The landfill treatment not only requires a large amount of natural space, but also the biogeochemical process between the landfills has a huge potential risk to the ecological safety of soil and groundwater. In recent years, in order to solve the problem of harmless treatment of poisonous substances, research has been focused on chemical treatment methods. This method was only suitable for waste water with low toxic content, wherein the oxidant generally cannot be reused. And this technology was expensive. UV oxidation method, adsorption-catalytic ozone oxidation and ultrasonic catalytic removal methods developed subsequently, are all treatment methods for industrial wastewater in principle, which can only improve the degradation efficiency of the poisonous liquids with low poisonous content. The degradation rate was still not up to the standard on treating the poisonous substances, and the generated waste liquid will also form a secondary pollution.
