High-efficiency treatment process for high-oil semi-coke wastewater

The invention relates to an efficient treatment process for high-oil semi-coke wastewater, which comprises the following steps: S100: pumping semi-coke wastewater into a first reaction tank, adding adaptive sulfuric acid into the reaction tank, and stirring until the pH value of the semi-coke wastewater is 3.5-4.5; s200, after stirring is stopped, polyaluminum chloride and polyacrylamide are added into the reaction tank, and after suspended solids in the semi-coke wastewater are coagulated and precipitated, supernate is pumped into a second reaction tank; s300, adding a compound demulsifier into the supernate, and adding adaptive polyacrylamide to carry out floc precipitation; s400, extracting the supernate into a third reaction tank, and carrying out iron-carbon micro-electrolysis reaction in the third reaction tank; s500, extracting supernate subjected to iron-carbon micro-electrolysis into a fourth reaction tank, adjusting the pH value of the supernate to be alkaline, and then carrying out deamination trea
