求翻译：微生物的生长要经历迟缓期、对数生长期、减速生长期和内源呼吸期即衰亡期，在衰亡期由于营养物质缺乏，代谢产物及有毒物质积累，细胞生长受到抑制，细胞分裂由缓慢而停止，细胞死亡率增加。因此在污泥驯化过程中要及时换水，防止死亡的菌体产生的有毒物质抑制正常代谢微生物的生长。是什么意思？

Microbial growth to go through a slow period, the decline phase of the growing season and the endogenous respiration of the logarithmic growth phase, deceleration in the decline phase due to the lack of nutrients, metabolites and the accumulation of toxic substances, cell growth was inhibited, cell

Microorganism's growth must experience the slow time, the logarithm vegetal period, the deceleration vegetal period and the endogene respiratory phase is a decline phase, in decline phase because the nutrients lack, the metabolite and the virulent material accumulate, the cell growth comes under the

Microbial growth experiences slow periods, logarithmic growth stage of decline and fall, slow growth and endogenous respiration, in a period of decline due to the lack of nutrients, metabolites and toxic substance accumulation, growth is stifled, cell division by slow and stop, cell death rate incre
