微生物营养需求

根据炼油废水成分分析的结果筛选降解烷烃、苯系物、苯酚等难降解化合物的高效降解菌，通过正交实验确定各组成菌株的最佳配比，制成复合微生物菌剂，根据营养需求添加KH2PO4作为助剂。

According to the analysis of refinery wastewater , high-efficiency microbe which can degrade alkane 、 benzene series 、 phenol were screened . The proportion of these microbe determined by orthogonal experiment . Microorganisms agent includes those microbe and KH_2PO_4 , act as aid agent , based on nutritional requirements .

实验在中温35℃条件下，接种驯化过发酵液进行厌氧发酵，研究接种液、固体含量（微生物处理负荷）及C/N（微生物营养需求）对厌氧发酵和产气效果的影响。

The effect of inoculation volume , disposal load ( solid content ) and nutrition demand ( C / N ) on anaerobic digestion has experimentally researched under the condition of 35 ℃ and once adding the waste .
