三氯化铁危废资源化利用研究

Study on Resource Utilization of Ferric Chloride Hazardous Waste

我国的危废产生量逐年稳中有增,目前危废的处置方法主要包括减量化、无害化和资源化。无害化处置主要是填埋和焚烧,均对环境造成一定的危害。资源化将是未来危废处置的大趋势。三氯化铁危废主要的资源化利用方向是蚀刻废液的循环利用和废水处理站除磷。危废资源化利用既节能环保,又能助推循环经济体系的建立,加快实现“双碳”目标。需要不断提升危废资源化利用的技术,赶上发达国家的脚步,才能致力于研究国际行业难题。

The amount of hazardous wastes produced in China has steadily increased year by year.At pres-ent,the disposal methods of hazardous wastes mainly include reduction,harmlessness and recycling.Harm-less disposal is mainly landfill and incineration,which cause certain harm to the environment.Recycling will be the general trend of hazardous waste disposal in the future.The main resource utilization direction of ferric chloride hazardous waste is the recycling of etching waste liquid and phosphorus removal in wastewater treat-ment station.The resource utilization of hazardous wastes can not only save energy and environmental protec-tion,but also promote the establishment of circular economy system and accelerate the realization of the"dou-ble carbon"goal.We need to constantly improve the technology of hazardous waste resource utilization to catch up with the pace of developed countries,so as to devote ourselves to the study of international industry problems.
