But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.
1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。

Methods: 2ethyl aniline was used as starting material of the synthesis and was processed by acetic anhydride acylation, strong nitric acid nitraction at low temperature, and desacyl synthesis to produce 2ethyl5nitro aniline. The product was then synthesized to 3methyl6nitro1Hindazole by using ringclosing reaction in the presence of NaNO2, and then ethylated to obtain 2,3diethyl6 nitro2Hindazole. The latter compound was then reduced by SnCl2/Hcl to get target compound 2,3diethyl6nitro2Hindazole.
以2乙基苯胺为原料经醋酐酰化、浓硝酸低温硝化及去酰基保护合成2乙基5硝基苯胺，后用亚硝酸钠关环得3甲基6硝基1H吲唑，经硫酸二甲酯甲基化得2，3二甲基6硝基2H吲唑，最后用氯化亚锡将其还原得到目标产物，通过1H NMR确定结构与目标产物一致。

Methods: 2-ethyl aniline was used as starting material of the synthesis and was processed by acetic anhydride acylation, strong nitric acid nitraction at low temperature, and desacyl synthesis to produce 2-ethyl-5-nitro aniline. The product was then synthesized to 3-methyl-6-nitro-lH-indazole by using ring-closing reaction in the presence of NaNO2, and then ethylated to obtain 2, 3-diethyl-6- nitro-2H-indazole. The latter compound was then reduced by SnC12/Hcl to get target compound 2, 3-diethyl-6-nitro-2H-indazole.
以2-乙基苯胺为原料经醋酐酰化、浓硝酸低温硝化及去酰基保护合成2-乙基－5-硝基苯胺，后用亚硝酸钠关环得3-甲基－6-硝基－1H-吲唑，经硫酸二甲酯甲基化得2，3-二甲基－6-硝基－2H-吲唑，最后用氯化亚锡将其还原得到目标产物，通过1HNMR确定结构与目标产物一致。
