【摘要】 通过对望塘污水处理厂的细格栅、厌氧池、曝气池、二沉池周边土壤及空气微生物测定,分析微生物分布状况,得知污水处理厂不同功能区域土壤和空气微生物含量随污水处理工艺的进行呈降低趋势。土壤和微生物鉴定结果表明,厂区土壤中微生物与普通土壤无明显差异,而空气微生物中含多种致病菌,形成的微生物气溶胶威胁人类健康。更多还原

【Abstract】 Microorganisms distribution were analyzed by determining the soil and air around fine grid,anaerobic tank,aeration pool and secondary settling tank of a sewage treatment plant. The results showed that microbial contents in those functional zones decreased in the process of sewage treatment. The microorganisms in plant soil had no significant difference with that in ordinary soil,while the plant air contained many kinds of pathogens which would do great harm to human health.更多还原
