Treatment method of explosive wastewater containing heavy metals

The invention provides a treatment method of explosive wastewater containing heavy metals, and belongs to the field of explosive wastewater treatment. Comprising the following steps: mixing the explosive wastewater containing the heavy metals with a chemical precipitant, and precipitating to obtain precipitated effluent; mixing the precipitation effluent with a flocculant, and carrying out flocculation to obtain flocculated effluent; adjusting the pH value of the flocculation effluent, and then carrying out micro-electrolysis strong oxidation to obtain micro-electrolysis effluent; performing biological selection treatment on the micro-electrolysis effluent to obtain biological selection effluent; the biological selection effluent is subjected to A/O biochemical treatment, and A/O biochemical treatment effluent is obtained; and decolorizing the A/O biochemical treatment effluent. The heavy metal-containing explosive wastewater treatment method provided by the invention has the advantages of low risk, low cost
