Zusammenfassung:The invention relates to immobilized microbial particles for domestic sewage decontamination and a preparation method thereof. The preparation method comprises the following steps: (1) pretreating loofah sponge; (2) loofah sponge modification; (3) preparing immobilized microbial particles; according to the immobilized microbial particles, the loofah sponge is adopted as a raw material, firstly, NaOH and H2O2 are used for carrying out high-temperature pretreatment on the loofah sponge, then mechanical activation and pretreatment are assisted, modification is carried out, finally, a denitrification strain is added to serve as a microbial main body, and all the steps have a synergistic effect; the preparation process is simple, the microorganism fixing effect is strong, the transmission efficiency of dissolved oxygen is high, the pollutant removal efficiency is high, and the application range is wide. 本发明涉及一种用于生活污水去污的固定化微生物颗粒及其制备方法,包括如下步骤:(1)丝瓜络预处理;(2)丝瓜络改性;(3)固定化微生物颗粒的制备;本发明固定化微生物颗粒采用丝瓜络原料,先利用NaOH和H2O2对丝瓜络进行高温预
