摘　　要：在SBR反应器中,控制其他条件不变,研究温度和pH值对皮革废水进行短程硝化的影响。结果发现:温度为(31±1)℃,pH值为7.8～8.2时,亚硝化效果相对最好;另外,系统在加入碳酸氢钠-氢氧化钠缓冲液后,亚硝化率相对提高很多,说明,pH值是影响亚硝化的一个重要因素。Influence of temperature and pH on the shortcut nitrosification of the leather wastewater was studied in a sequencing batch reactor （ SBR）, with the other factors steady. The results show that the optimal nitrosification condition is that the temperature is （31 ± 1 ） ℃ and the pH is 7.8 - 8.2. In addition, the nitrosification is enhanced a lot after the sodium bicarbonate - sodium hydroxide buffer solution is added into the system. The results indicate that pH is an important factor affecting the nitrosification.
