The invention discloses a reverse osmosis membrane scale inhibitor, and a method for preparing and using the same. The reverse osmosis membrane scale inhibitor contains polymeric scale inhibitors and components selected from phosphono-carboxylic acid scale inhibitors, organic phosphonic acid scale inhibitors and auxiliary agents. The reverse osmosis membrane scale inhibitor is high in scale inhibition efficiency, small in addition, environmental-friendly, and is suitable to be used in environments with organic substances and in a reverse osmosis membrane treatment process for recycling sewage. For wastewater effluents from a biochemical treatment process with a chemical oxygen demand (COD) less than 150mg/l, the reverse osmosis membrane scale inhibitor has good scale inhibition effect on CaCO3, CaCO4, BaSO4, SrSO4 and so on, and can ensure the normal operation of a membrane component and prolong the service life of the membrane component.
