摘要
为实现废水处理过程中的短程硝化及反硝化脱氮中亚硝酸盐的积累以控制硝化反应的类型,以试验的方式,采用SBR工艺研究了pH值对不含海水的城市生活污水和含30%海水的城市生活污水短程硝化的影响.试验结果表明:对于不含海水的城市生活污水,单纯提高pH值来提高游离氨浓度并不一定能够实现短程硝化;对于含30%海水的城市生活污水,可直接实现短程硝化;海水盐度是实现短程硝化的影响因素之一.
In order to realize accumulation of nitrite during denitrogenating in shortcut nitrification and shortcut anti-nitrification for controling the type of nitrification reaction,some experiments were done.In these experiments,using SBR technique,pH value effect on shortcut nitrification to municipal sewage which had not contained seawater and had contained 30% seawater.The results of experiments indicat that shortcut nitrification can uncertainly be achieved in treating municipal sewage without seawater to raise only the value of pH to raise the concetration of free ammonia,shortcut nitrification can be achieved in treating municipal sewage containing 30% seawater,and seawater is a factor of effect on shortcut nitrification.
