Abstract


Oxidation coagulation - the composite filtration - reverse osmosis combined process waste water processing Daqing Refining Company . For reuse of sewage water quality and treatment requirements , design the pretreatment process and operating parameters , and anti-pollution variation of the reverse osmosis membrane performance study . The results showed that the coagulation and filtration can be effective to remove water and most of the suspended solids, turbidity, and partially ionic and chrominance , pretreated water to meet the requirements of the reverse osmosis membrane inlet , and water was mainly influenced by the filtration rate and the amount of flocculant dosing . Fouling reverse osmosis water to meet the design requirements , but after a period of operation , the membrane fouling , operating pressure will gradually rise , decline in water yield after chemical cleaning to restore its performance .
