固定氨氧化细菌的煤矸石颗粒及其制备方法
摘要：
本发明公开了固定氨氧化细菌的煤矸石颗粒。煤矸石颗粒清洗后经CuCl2、硫代乙酸钾、PbCl2、FeCl3制备的混合液改性后得到物质B；物质经B经CoCl2、CeCl3、NaOH、NaCl、SrCl2制备的混合液改性后得到物质C；物质经C经2‑吡咯甲醛、乙醛酸制备的混合液改性后得到物质D；在物质D上固定氨氧化细菌后得到的物质即为固定氨氧化细菌的煤矸石颗粒。本发明的有益效果是，制得的固定氨氧化细菌的煤矸石颗粒具有菌株活性高、能高效降解废水中氨氮的功能。
摘要（英）：

The invention discloses coal gangue particles for immobilizing ammonia oxidizing bacteria. The preparation method comprises the following steps: cleaning coal gangue particles, and modifying with mixed liquid of CuCl2, potassium thioacetate, PbCl2 and FeCl3 to obtain a substance B; modifying the substance B with mixed liquid of CoCl2, CeCl3, NaOH, NaCl and SrCl2 to obtain a substance C; modifyingthe substance C with mixed liquid of 2-pyrrole formaldehyde and glyoxylic acid to obtain a substance D; immobilizing ammonia oxidizing bacteria on the substance D to obtain the coal gangue particles for immobilizing ammonia oxidizing bacteria. The coal gangue particles and the preparation method thereof disclosed by the invention have the following beneficial effects: the prepared coal gangue particles for immobilizing ammonia oxidizing bacteria realize high activity of bacterial strains and can effectively degrade ammonia nitrogen in wastewater.
