  摘要:

  今朝黑臭水体底泥凡是采取化学或生物方式进行异位管理，生物法因为简单易操作、处置本钱较低而被普遍利用，并可以或许为后续的底泥资本化操纵供给前提。为探讨更适合的生物处置方式，明白生物处置进程中的微生物群落转变纪律，别离采取分歧品种的纯生物菌剂（硝化细菌、反硝化细菌、光合细菌和芽孢杆菌）对黑臭水体底泥进行异位处置，经由过程投加分歧剂量的纯菌剂，比力反映前后底泥中的总氮、总磷、无机质和含水率的转变。成果注解，在常温（20±5） ℃下颠末30 d的处置，底泥中含水率、总氮和无机质含量都有分歧水平的下降。此中，投加量为35 mg/L的反硝化细菌实验组处置结果最好，总氮和无机质去除率别离到达59.90%和20.93%。三维荧光光谱阐发注解，投加纯生物菌剂处置后，底泥中的年夜份子无机物浓度下降，小份子物资浓度有分歧水平的升高，申明生物菌剂可以或许提高底泥中微生物的活性，不但增进了无机物的降解，还为反硝化反映供给了碳源，增进了底泥中总氮的去除。另外，高通量测序也注解，投加菌剂的实验组样本中，都呈现了必然品貌的Thiobacillus、Sulfurovum、Sulfuricurvum和Sulfurimonas，且在芽孢杆菌实验组和光合细菌实验组中比例较高，四个菌属总比例别离到达13.24%和14.80%。这四个菌属可以或许介入硫代谢，对底泥中无机质（如卵白等）的降解起到主要感化。

  Abstract:

  At present, chemical or biological methods are usually employed for ectopic treatment of black and odorous water sediment. Biological method is widely applied because of its simplicity and low treatment cost, and it is beneficial to the subsequent utilization of sediment. In order to investigate a suitable biological treatment process and demonstrate the variations of microbial community during the biological treatment process, four types of biological agents (nitrifying bacteria, denitrifying bacteria, photosynthetic bacteria, and bacillus) were used for ectopic treatment of black and odorous water sediment. Different dosages of biological agents were added, and variations of total nitrogen (TN), total phosphorus, organic matter and water content in the sediment before and after the reaction were compared. After treatment of 30 days at room temperature (20±5) ℃, water content, total nitrogen, and organic matter in the sediment all decreased to different degrees. Among them, the denitrifying bacteria group with dosage of 35 mg/L had the best treatment efficiency: removal efficiencies of total nitrogen and organic matter reached 59.90% and 20.93%, respectively. Three-dimensional fluorescence spectrum analysis showed that the concentration of macromolecular organic matter in the sediment decreased and the concentration of small molecular matter increased in different degree after adding pure biological agent. This indicated that the biological agents improved the activity of microorganisms in the sediment, not only promoting the degradation of organic matter, but also providing carbon source for denitrification and promoting the removal of total nitrogen in the sediment. Furthermore, highthroughput sequencing also showed that Thiobacillus, Sulfurovum, Sulfuricurvum and Sulfurimonas were observed in all experimental groups with addition of biological agents, and the higher proportions in experimental groups with addition of bacillus and photosynthetic bacteria (total proportions of the four genera reaching 13.24% and 14.80%, respectively) were detected. These four genera were related to sulfur metabolism and might play an important role in the degradation of organics, such as proteins, in the sediment.
