摘　　要：剩余活性污泥完全资源化利用微生物集成技术包括:使用土著PHA合成菌回注法驯化并发酵活性污泥,生产生物降解材料聚羟基脂肪酸酯(PHA);采用土著嗜酸性氧化亚铁硫杆菌和氧化硫硫杆菌进行生物淋滤,去除重金属;以解磷菌和解钾菌为菌种,进行固态发酵,生产生物菌肥。结果表明,500 L中试PHA占挥发性悬浮固体的20%以上;重金属含量达到国家排放要求;生物菌肥中活菌数大于1×108个/g以上。实现了剩余活性污泥的近零排放。Microbial technology for the comprehensive utilization of excess activated sludge,i.e.pro-duction of PHA by adding native PHA synthesis-bacteria during domestication and fermentation for ac-tivated sludge;bioleaching activated sludge to remove heavy metals by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans;production of biological fertilization by using solid state fermenta-tion for P-solubilizing bacteria and K-releasing bacteria.Results showed that the ratio of PHA in VSS was above 20% under the 500 L pilot scale;the contents of heavy metals in activated sludge accorded with the National Discharge Standard;the number functional bacteria for microbial fertilizer was above one hundred million.
