Abstract

The invention provides a pyrolysis process wastewater treatment system and method based on a double-circulation fluidized bed boiler, and belongs to the field of wastewater treatment. A circulating fluidized bed pyrolyzing furnace, a waste water pool, a waste water pump, an atomizing spray gun capable of advancing and retreating, a compressed air tank, a first manual valve, a second manual valve and other components are additionally arranged on the basis of an existing power generation system, and the waste water treatment system based on the existing power generation system is provided. The composition structure of the pyrolysis process wastewater treatment system can be simplified, the pyrolysis process wastewater treatment process is shortened, the heat source circulating back to the circulating fluidized bed combustion furnace is fully utilized in the pyrolysis process wastewater treatment process, and the wastewater treatment cost can be saved. Besides, the pyrolysis process wastewater is incinerated in the circulating fluidized bed combustion furnace, so that organic matters in the pyrolysis process wastewater can be converted into harmless small molecules such as H2O and CO2 at high temperature, meanwhile, dioxin is prevented from being generated, and environmental problems cannot be caused.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a pyrolysis process wastewater treatment system and method based on a double-circulating fluidized bed boiler. Background technique [0002] Pyrolysis process wastewater refers to the raw wastewater generated during the coal pyrolysis process and purification process. The treatment process generally includes air flotation, precipitation, filtration and extraction, etc. The pyrolysis process wastewater is recovered after removing oil, ash and phenolic ammonia resources. , into the subsequent biochemical treatment process for treatment. Pyrolysis process wastewater usually contains some refractory organic matter. The current method of treating pyrolysis process wastewater usually has the disadvantages of long process, large system footprint, high cost, etc., and dioxins will be produced during the treatment of organic matter, which will cause environmental pollution p...
