摘要
分别用沸石柱及沸石微生物柱处理生活污水中的氨氮,并研究沸石质量、pH值、吸附时间对沸石去除氨氮的影响.研究表明:沸石投加量越大,氨氮去除效果越好,沸石的吸附容量越小;pH值对氨氮的去除影响较大,pH在8附近时氨氮去除效果最好;随时间的延长能增加沸石对氨氮的去除.对于进水氨氮为60.34mg/L的生活污水,沸石柱去除效率最低可达77.43%,沸石微生物柱的去除效率最低可达87.32%.
The study is focused on the ammonia nitrogen treatment of sewage with zeolite col- umn and zeolite microbial column respectively,at same time, the influences of zeolite dosage, pH value and adsorption time on the removal rate of ammonia nitrogen are experimented. The research shows that： the bigger zeolite dosing quantity takes, the better the ammonia nitro- gen removal efficiency becomes, and the smaller the zeolite adsorption capacity; pH value of ammonia nitrogen removal influence is bigger, and pH in 8 nearby removing ammonia nitro- gen gets better; the extension of adsorption time can increase zeolite of ammonia nitrogen re- moval. To feed water quality for 60. 34 mg/L life sewage,the minimum removal rate of am- monia nitrogen is 77.43 % by single zeolite column, zeolite microbial column removal efficien- cy of minimum will amount to 89.43%.
