Problems solved by technology

Traditional sewage treatment methods have problems such as high cost, low efficiency, and secondary pollution
In sewage treatment, microorganisms are commonly used to treat organic wastewater, but when using microorganisms to treat organic wastewater, there will be two problems. For general organic wastewater, COD can only be reduced to 60-120. For high-concentration organic wastewater or with certain toxicity For organic wastewater, the treatment effect of microbial methods is not good; the physical treatment of wastewater is mainly through adsorption, extraction, electrolysis, ion exchange, reverse osmosis, etc., but the equipment cost and daily operation cost of this treatment system are relatively high, which is higher than that of biological treatment. The method consumes more energy and materials. Therefore, when deciding on the treatment process, it is necessary to conduct a technical, economic comparison and a comprehensive analysis of the impact on the environment based on the requirements for the quality of the effluent water.
[0003] Now the wastewater treated by microorganisms or high-concentration organic wastewater is treated by ozone treatment. The ozone catalysts used for sewage treatment are divided into granular catalysts and powder catalysts, but the catalysts currently used are large in consumption and high in cost. Can produce results that are difficult to recover due to churn

Description

technical field [0001] The invention relates to the field of catalysts for sewage treatment, in particular to a recyclable magnetic powdery ozone catalyst and a preparation method thereof. Background technique [0002] There are many methods for treating sewage, which can be generally classified into physical methods, chemical methods and biological methods. Traditional sewage treatment methods have problems such as high cost, low efficiency, and secondary pollution. In sewage treatment, microorganisms are commonly used to treat organic wastewater, but when using microorganisms to treat organic wastewater, there will be two problems. For general organic wastewater, COD can only be reduced to 60-120, for high-concentration organic wastewater or with certain toxicity.
