摘要
固定化微生物技术是将特选的微生物固定在选定的载体上，使其高度密集并保持生物活性，在适宜条件下能够快速、大量增殖的生物技术。这种技术应用于废水处理，有利于提高生物反应器内微生物（尤其是特殊功能的微生物）的浓度，有利于微生物抵抗不利环境的影响，有利于反应后的固液分离，缩短处理所需的时间。本文研究的主要是利用琼脂包埋法对微生物进行固定，固定之前处理最佳CODc，浓度为1000mg／L，处理效果为80％左右，固定后CODCx处理浓度为2000mg／L，效果达到85％以上。实验得出固定后微生物处理有机废水的最佳条件为：CODCx为2000mg／L，pH为6．0～8．0，处理时间8h。
Immobilized microorganism technology is a biotechnology of selected microorganisms fixed in the selected carrier, to maintain the biological activity of high density, and in appropriate conditions can rapidly proliferated. The technology used in wastewater treatment, help to improve bioreactor concentration of microorganisms （Especially the special features of micro - organisms）. Conducive to microbial resistance impact of adverse environmental and solid - liquid separation after the reaction , Shorten the reaction time. AGAR was mainly used to embedding method of immobilized microorganisms, fixed before treatment for optimal concentration for 1 000 mg/L, treatment effect to 80%, fixed post - processing concentration for 2 000 mg/L, treatment effect reach 85 %. Experiment results microbial treatment of organic waste water after fixation the best conditions were ：CODcr concentration of 2 000 mg/L, pH was 6. 0 - 8.0, processing time was 8 h.
