Problems solved by technology

However, the physical method does not completely remove the pollutants, but only changes the form and mode of the pollutants; the biochemical method is a relatively mature industrial method, which has good treatment effect, strong adaptability, and low treatment cost, but due to the pretreatment The technology is not up to standard, and the wastewater often needs to be diluted with a large amount of water, resulting in huge treatment equipment, low load, high investment and operating costs; due to the presence of high concentrations of toxic substances and salt in the wastewater and the complex components in the organic wastewater, biological Difficult to run the treatment process, the degradation of organic matter is not complete, and the water quality after treatment is difficult to meet the standard
Therefore, it is difficult to meet the economic and technical requirements by using general wastewater treatment methods, and seeking efficient and low-cost methods for treating high-concentration organic wastewater has become a hot research topic for domestic and foreign scholars at this stage.

Description

technical field [0001] The invention relates to the technical field of organic pollutant treatment, in particular to a composition for degrading polycyclic organic substances, a preparation method and application thereof. Background technique [0002] With the rapid development of industry, the discharge of various types of industrial wastewater is also increasing year by year. Among them, high-concentration organic industrial wastewater such as petroleum / chemical wastewater, textile / printing and dyeing wastewater, pharmaceutical / food wastewater, and coking / smelting wastewater has complex components and contains a large amount of refractory organic matter, especially petroleum / chemical wastewater and coking wastewater. Polycyclic compounds (phenol and phenol homologues, and polycyclic compounds such as benzopyrene, anthracene, naphthalene, etc.). And due to production time, process and other reasons, the water quality of wastewater containing refractory organic matter also ...
