Rapid treatment method for petrochemical wastewater

The invention provides a rapid treatment method for petrochemical wastewater. The method comprises the following steps: first performing a first treatment on the petrochemical wastewater by using a first treatment agent, and performing filtering to obtain a first filtrate; then performing a second treatment on the filtrate by using a second treatment agent, performing filtering to obtain a secondfiltrate, and discharging the second filtrate; wherein the first treatment agent comprises an amino compound, polyacrylamide, chitosan, dithioformic acid, sodium carbonate, lignocellulose and ceramicmicro-powder; and the second treatment agent comprises polyaluminum chloride, ferric sulfate, citric acid, tannin, stone powder, modified diatomite, activated carbon, titanium tetrachloride, aluminumsulfate, poly(diallyldimethylammonium chloride), zinc chloride, ethyl cellulose and titanium dioxide powder. The method can effectively treat the wastewater produced by petrochemical industry, removesammonia compounds, trace he
