| 摘 要： | 目的 以粉煤灰与池塘底泥为主要原材料，通过固定化有效微生物群落(effective microorganisms，EM)的方式制备具有高效去氮除磷的生物陶粒，用于处理污染的养殖水体。 方法 利用等温吸附试验确定最佳粉煤灰陶粒的配比，将粉煤灰陶粒与EM固定，在氨氮、总氮、总磷质量浓度分别为50、55、20 mg·L?1的模拟水产养殖废水中处理6 d。 结果 在预热温度300 ℃，烧制温度1 100 ℃条件下，当粉煤灰陶粒中质量比为m(粉煤灰)∶m(活性底泥)∶m(石灰石粉末)∶m(铁粉)=50∶40∶5∶5时，改性粉煤灰陶粒固定化EM对模拟水产养殖污水中氮磷的净化效果最好。6 d后，氨氮、总氮和总磷的最大去除率分别为98.67%、93.80%和45.35%。 结论 粉煤灰陶粒本身具有一定氮磷吸附净化能力，EM固定化陶粒可强化净水效果。图5表4参24

| Abstract: | Objective With ash and pond sediment as main raw material, the purpose of this research is to prepare biological ceramics with efficient nitrogen and phosphorus removal for treatment of polluted aquaculture water by immobilizing effective microorganism (EM) community. Method The optimal proportion of fly ash ceramsite was determined by isothermal adsorption test. The fly ash ceramsite was fixed with EM and treated for 6 days in simulated aquaculture wastewater with ammonia nitrogen, total nitrogen and total phosphorus concentrations of 50, 55 and 20 mg·L?1. Result Under the preheating temperature of 300 ℃ and the firing temperature of 1 100 ℃, when the mass ratio of fly ash ceramsite was m (fly ash)∶m (active sediment)∶m (limestone powder)∶m (iron powder)=50∶40∶5∶5, the modified fly ash ceramsite immobilized EM had the best purification effect on nitrogen and phosphorus in the simulated aquaculture wastewater. After 6 days, the maximum removal rates of ammonia nitrogen, total nitrogen and total phosphorus were 98.67%, 93.80% and 45.35%, respectively. Conclusion Fly ash ceramsite itself has a certain adsorption and purification capacity of nitrogen and phosphorus. After the immobilization of ceramsite with EM, water purification effect can be enhanced. Ch, 5 fig. 4 tab. 24 ref.] |
