Organic solid waste incineration fly ash harmless treatment system

The invention relates to an incineration fly ash treatment technology in the field of organic solid waste treatment, in particular to a fly ash harmless treatment system. The system is mainly divided into four parts, namely a fly ash acid leaching system, a fly ash and acid leaching liquid mixture elution system, a wet fly ash washing and drying system and a heavy metal filtrate electrodialysis concentration system. The leaching rate of Pb, Zn, Cd and Cu in the fly ash treated by the fly ash harmless treatment system is higher than 96%, the tedious treatment process is reduced, the operation is convenient, and the wastewater treatment cost is greatly reduced. 本发明涉及有机固废处理领域的焚烧飞灰处理技术，具体涉及一种飞灰无害化处理系统，主要分为四个部分，分别为飞灰酸浸系统，飞灰与酸浸液混合物的洗脱系统，湿飞灰水洗干燥系统，重金属滤液电渗析浓缩系统。本发明飞灰无害化处理系统处理后飞灰中Pb、Zn、Cd和Cu的浸出率高于96%，减少了繁琐的处理过程，操作方便，大大减少了废水处理的成本。
