Embodiment 1
[0078] Adopt the method of the present invention to attach figure 1 The integrated process in the process treats the saline wastewater of an oil refinery, and the water quality indicators are as follows:
[0079] serial number
[0080] The system includes the following steps:
[0081] a. Pretreatment process
[0082] Wastewater first enters the crystallization defluorination reactor for pretreatment. After pretreatment, part of the suspended solids, organic matter and fluoride ions in the wastewater are removed.
[0083] Pretreatment effluent: turbidity ≤ 130NTU, COD ≤ 1700mg / L, effluent flows into the comprehensive wastewater regulating tank for water quality and quantity regulation.
[0084] b. Biochemical treatment process
[0085] The biochemical treatment process unit adopts anaerobic-anoxic-aerobic (A 2 O) process, COD, nitrogen, and phosphorus are removed from wastewater.
[0086] After the biochemical treatment unit, the COD of the wastewater is ≤170mg / ...
