Abstract

The invention discloses an ammonium perchlorate wastewater processing method, and the method comprises the following steps: obtaining an intermediate product hydrogen and volatile fatty acid through akitchen waste anaerobic digestion hydrogen and acid production stage; providing an electron donor and a carbon source for the process of reducing ammonium perchlorate by perchlorate reducing bacteriaby utilizing the intermediate product hydrogen and volatile fatty acid; reducing ammonium perchlor`ate into chloride ions by adopting a three-stage degradation combined process of hydrogen autotrophic reduction, organic acid heterotrophic reduction and iron / sulfur autotrophic reduction to reduce the concentration of the ammonium perchlorate wastewater and complete the processing of the ammonium perchlorate wastewater . According to the method, the removal effect of the ammonium perchlorate wastewater can be remarkably improved, meanwhile, generated biogas is used as clean energy for life andproduction, and the economic rationality and the process operability are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of environmental biology and relates to anaerobic digestion and perchlorate biological reduction methods, in particular to a treatment method for ammonium perchlorate wastewater. Background technique [0002] As a strong oxidant, ammonium perchlorate has been widely used in rocket solid propellants, missile fuels, explosives and other aerospace and military industries in recent years. Ammonium perchlorate in discarded rocket engines and explosives will produce a large amount of ammonium perchlorate wastewater, which needs to be solved urgently. [0003] At present, the treatment methods of ammonium perchlorate wastewater include physical chemical method and biological method. Physicochemical methods include activated carbon / biomass adsorption method, ion exchange method, reverse osmosis membrane separation method (reverse osmosis RO, ultrafiltration UF, nanofiltration NF), etc. Among them, activated carbon ...
