| 人工生物净化 Artificial biological purification 人工生物净化，是人为的创造条件使微生物大量繁殖，人工驯化微生物，利用微生物质新陈代谢降解水中有机物的方法，是目前国内外对生活污水二级处理的主体工艺。主要优点为：处理效果稳定，可以在一定范围内调节处理效率，处理工艺占地面积小。主要缺点为：投资高、运行费用高、管理复杂，需操作人员较多。 Artificial biological purification is a method of creating artificial conditions to make a large number of microorganisms multiply, domesticating microorganisms and degrading organic matters in water by metabolism of microorganisms. It is the main process of secondary treatment of domestic sewage at home and abroad at present. The main advantages are: the treatment effect is stable, the treatment efficiency can be adjusted within a certain range, and the treatment process covers a small area. The main disadvantages are: high investment, high operating cost, complex management and more operators. 主要处理工艺如下：生活污水一沉淀(或气浮)一生物膜法一生物滤池(生物转盘、接触氧化、活性污泥法)一曝气池(氧化沟)一沉淀(或气浮)一消毒一出水 The main treatment process is as follows: domestic sewage - sedimentation (or air flotation) - biofilm process - biofilter (biological turntable, contact oxidation, activated sludge process) - aeration tank (oxidation ditch) - sedimentation (or air flotation) - Disinfection - effluent |
