摘要

摘要: 改性玄武岩纤维(MBF)是一种新型无机微米级纤维填料。为了研究MBF填料的生物亲和性,评估其推广应用的可行性,采用扩展DLVO理论构建了细菌与MBF填料间附着行为的动力学数学模型,并将MBF作为生物接触氧化反应池的填料处理合成市政污水,初步评价MBF填料的污水处理效果。结果表明:枯草芽孢杆菌在MBF填料表面发生了牢固且较强的黏附行为,二者间不存在能垒障碍,故MBF填料具有较高的微生物附着能力。此外,基于MBF填料的生物接触氧化反应器启动较快,可长期维持稳定运行。COD、NH₃-N和TN平均去除率分别可达到94%、99.5%和97%。因此,MBF填料在环境工程领域具有较好的推广应用前景,可作为传统有机填料的替代品。

Abstract: Modified basalt fiber(MBF) is a new type of inorganic micron-sized fiber carrier. To investigate the bioaffinity of the MBF carrier and evaluate its feasibility in practical application, the extended DLVO theory was used to construct the dynamics model of the bacteria adhesion behaviors on MBF carrier, and the biological contact oxidation reactor filled with MBF carrier was operated to treat the synthetic municipal wastewater and evaluate its treatment efficiency. The results showed that there was no energy barrier between Bacillus subtilis(B. subtilis) and MBF, allowing B. subtilis strong adhesion onto MBF. Therefore, the MBF carrier had high microbial immobilization capacity. In addition, the biological contact oxidation reactor filled with the MBF carrier started up quickly and maintained long-term stable operation. The average removal efficiencies of COD, ammonia nitrogen and total nitrogen were up to 94%, 99.5% and 97%, respectively. Therefore, the MBF carrier has a promising applicability in engineering practice, which provides an alternative to conventional organic carrier.
