Biological enhancement treatment method and device for coal gasification wastewater

The invention provides a biological enhancement treatment method and device for coal gasification wastewater. The device comprises an enrichment culture tank, a PH adjusting solution tank and a nutrient solution tank; an aeration system used for providing oxygen needed in the culture process and a temperature control subsystem used for controlling the temperature, a PH adjusting subsystem and a stirring subsystem used for controlling the PH, a nutrient solution dosing subsystem used for controlling the conveying rate of a culture solution, and an inoculation and bacterial liquid conveying subsystem and an automatic control system are arranged in the enrichment culture tank. With the biological enhancement treatment method and device for coal gasification wastewater adopted, the ammonia nitrogen treatment load can be effectively improved, the sludge concentration is reduced, the sludge discharge amount is reduced, and the sludge treatment cost is reduced. 本发明提出一种煤气化废水生物强化处理方法和装置，所述装置包括富集培养罐，PH调节溶液槽和营养液槽，所述富集培养
