Abstract

The invention discloses a biochemical treatment system and method for pressurized gasification waste water of crushed coal, which belongs to the field of waste water treatment. The coagulation reaction tank, the coagulation sedimentation tank and the clean water tank are connected in sequence; there is a defoaming water pipe between the clean water tank and the anoxic-multi-stage aerobic system; the lift pump is equipped with a device for introducing crushed coal pressurized gasification wastewater pretreatment effluent Water inlet pipe; the clean water pool is provided with an outlet pipe for discharging treated water. In this system, the dual-cycle anaerobic filler reaction system hydrolyzes large molecular organic matter into small molecular organic matter under anaerobic conditions, improving the biodegradability of wastewater; The effluent COD, ammonia nitrogen and total nitrogen are greatly reduced. The system has the advantages of good processing effect, low operation cost and simple operation.

Description

technical field

[0001] The invention relates to the field of waste water treatment, in particular to a biochemical treatment system and method for crushed coal pressurized gasification waste water. Background technique

[0002] The crushed coal pressurized gasification process (represented by Lurgi furnace) is a coal gasification process widely used in coal gasification, especially coal-to-natural gas. The process is mature, and the investment and operation costs are relatively low, but its wastewater treatment restricts the application of this technology. Crushed coal pressurized gasification wastewater contains a large amount of refractory organic compounds such as phenols, aromatic hydrocarbons, and heterocyclic compounds; it also contains high concentrations of oil, ammonia nitrogen, and salt; its biodegradability is poor, and it has an inhibitory effect on microorganisms , In addition, the fluctuation range of the wastewater quality is large, so the conventional bioche...
