A treatment agent for water quenching and slag flushing of a yellow phosphorus slag using reverse osmosis concentrate (ROC), comprising the following components in mass percentage:

• 3% to 10% of a dispersant, 1% to 3% of a wetting agent, 3% to 10% of a scale inhibitor, 3% to 8% of a carbon steel corrosion inhibitor, 0.5% to 1% of a copper corrosion inhibitor, 5% to 25% of a complex cleaning agent, and water as a balance;
• wherein
• the scale inhibitor comprises polyamino polyether methylene phosphonic acid (PAPEMP) and a dendritic polymer poly (amidoamine) (PAMAM);
• the wetting agent comprises polyethylene glycol (PEG);
• the carbon steel corrosion inhibitor comprises 2-hydroxyphosphonoacetic acid (HPAA);
• the copper corrosion inhibitor comprises 5-butyl-benzotriazole;
• and
• the complex cleaning agent comprises citric acid and formic acid.
