The paper discussed the processing conditions of gasification wastewater treatment. The results showed that the treatment effect was affected by factors on temperature influence water load and pH under the condition influenting 1 h, aerating 8 h, quiescing 2 h and draining 0.5 h, among which temperature is the greatest influence factor, the second was influence water load and pH was the least, the optimal condition for gasification wastewater treatment was COD 2 000 mg·L~(-1), temperature 30 °C, pH 7.0 determined by orthogonal experiment, and the COD removal rate reached 80.7%. It is also found that SBR processing gasification wastewater has the certain ability against impacting load.
