  摘要:

  针对污水厂进水碳源不足的问题，采取南边某污水厂残剩污泥进行碱性发酵尝试，系统考查了产酸量、氨氮和总磷释放量，研究微生物对发酵液的操纵和污泥脱水环境。成果注解：在pH值=10、25 ℃前提下，发酵第7天，挥发性无机酸含量到达峰值3 262 mg/L，此中乙酸堆集量占比76.52%。采取发酵液作为原料，微生物反硝化进程、硝化进程、厌氧释磷进程均不受影响。在pH值为4的前提下，聚合硫酸铁投加量（以干基计）为70 kg/t时，发酵污泥含水率可降至64.02%。污泥碱性发酵后可发生年夜量脂肪酸，且发酵液中的无机物组分能作为微生物需要的反硝化碳源，对硝化进程、磷的释放均未发生较着晦气影响，发酵发生的污泥颠末聚合硫酸铁调度后脱水机能杰出。

  Abstract:

  Excess sludge from a sewage treatment plant in South China was fermented under alkaline condition to solve the problem of insufficient carbon source in sewage treatment plants. The acid production, ammonia nitrogen and total phosphorus release were systematically investigated, and the utilization of fermentation broth by microorganisms and sludge dewatering performance were explored. When pH and temperature were 10 and 25 ℃, the volatile organic acids content reached the peak of 3 262 mg/L on the 7th day of fermentation, among which the accumulation of acetic acid accounted for 76.52%. The processes of microbial denitrification, nitrification and anaerobic phosphorus release were not affected by using fermentation broth as raw material. When pH and PFS dosage of dry base were 4 and 70 kg/t, the water content of fermented sludge could be reduced to 64.02%. A large number of fatty acids were produced after alkaline fermentation of sludge, and the organic components in the fermentation broth could be used as the denitrifying carbon source required by microorganisms, which had no significant adverse effect on the nitrification process and phosphorus release. In addition, the sludge produced by fermentation had a good dewatering performance after PFS conditioning.
