  • Oily sewage pretreatment method and device without air floatation
    Patent number: 12017939
    Abstract: An oily sewage pretreatment method without air flotation, comprising the following steps: (a) sedimentation separation: performing sedimentation separation on oily sewage to implement preliminary separation of oil, sludge, and water; (b) boiling bed separation: performing boiling bed separation on the oily sewage obtained by the preliminary separation to further remove dispersed oil, sludge, and sand from the oily sewage; (c) shape coalescence separation: performing shape coalescence separation on the oily sewage obtained by the boiling bed separation in step (b) to implement demulsification, coalescence, and separation of emulsified oil; and (d) biochemical treatment: the effluent obtained in step (c) directly enters an AOH biochemical system, an air flotation unit is omitted. Also disclosed is an oily sewage pretreatment apparatus without air flotation.
