摘要
将采用PVA-HzB04法制得的包埋固定化微生物凝胶小球引入SBR工艺中，通过平行试验比较了普通SBR反应器（N1）与投加包埋固定化微生物凝胶小球的SBR反应器（N2）的脱氮性能，分析了包埋固定化微生物强化SBR工艺脱氮性能的杼陛。研究结果表明：在相同的运行条件下，N2反应器的NH4＋-N及TIN的去除率较N1反应器分别提高了4．4％-32．8％、34．1％～50．9％，且表现出明显的抗冲击负荷能力；同时通过典型周期内不同反应器各形态氮随时间的变化研究发现，该反应器发生了很好的同步硝化反硝化作用，说明包埋固定化微生物对SBR反应器的脱氮性能有很好的强化作用。N2为提高SBR反应器得脱氮性能提供了新思路。
The embedded immobilized microorganisms gel pellet using PVA-H2BO4 method was applied into SBR process, and the characteristics of nitrogen removal between conventional SBR reactor （N1） and SBR reactor added embedded immobilized microorganisms gel pellet （N2） were investigated through the parallel experiment. The enhanced characteristics of nitrogen removal of SBR process by embedded immobilized microorganism were analyzed. Results showed that with the same operation conditions, N2 removal rate of NH4＋-N and total inorganic nitrogen increased by 4.4%-32.8% and 34.1%-50.9% than N1, with obvious improved ability of resistance load. Through studying different nitrogen forms in the different reactors in typical cycle, the reactor was found to have good simultaneous nitrification and denitrification, which indicated that immobilized microorganism technology can strengthen nitrogen removal of SBR reactor. It also provided a new idea on improving the performance of nitrogen removal of SBR reactor.
