Metagenomic analysis on resistance genes in water and microplastics from a mariculture system
《环境科学与工程前沿(英文)》 2022年 第16卷 第1期 页码 4-4 doi: 10.1007/s11783-021-1438-y
Microplastics existing widely in different matrices have been regarded as a reservoir for emerging contaminants. Mariculture systems have been observed to host microplastics and antibiotic resistance genes (ARGs). However, more information on proliferation of ARGs and metal resistance genes (MRGs) in mariculture system at the presence of microplastics is needed.

Reviewed the change of ARGs and ARB in full-scale urban drinking water systems. Conventional processes are more promising than BAC process in ARGs removal. Mechanisms of ARGs enrichment and spread in BAC filter and DWDSs are discussed. Raise the need of future research on ARGs and ARB change in building plumbing systems.

合理确定衬砌水压力是海底隧道结构设计的关键所在。采用复变函数和地下水动力学理论,推导了圆形海底隧道衬砌外水压力解析法计算公式,经对比验证,精度高、适用性广。通过海底隧道水压力模型试验研究得到,全封堵防水方式下,衬砌背后水压不能折减;限量排放时,衬砌背后水压力随排水量的增加而减小,建立了限量排放下的水压力计算公式,得到现场实测结果验证。研究成果应用于国内第一条海底隧道──厦门翔安海底隧道,为“以堵为主、限量排放”的支护结构设计和海底风化槽地段注浆堵水方案的制订提供了关键技术参数,现场应用成效良好。相关研究成果对后续海底隧道工程具有一定借鉴意义。

Reclaimed water threatens the ecological safety of the Chaobai River. SMX, TMP, and SDZ were the first three abundant antibiotics in the research area. SRGs and intI1 were widespread with high abundance after reclaimed water recharge. The SRGs values followed the sequence: Summer>autumn>spring>winter. Strong correlations were detected between SRGs and environmental factors.

高压富水充填溶腔具有水量大、水压高、规模范围大、充填介质复杂的特征,工程施工风险极高,采用传统的注浆法进行处理,受地层的不均一性、材料选择、技术水平的影响,难免会出现注浆盲区,施工中一旦注浆盲区被高压水击穿,将会发生大规模突水突泥,造成灾害。针对宜万铁路所遇到的高压富水充填溶腔,通过科技攻关,提出采取释能降压新技术进行处治。经现场实践,安全、经济、可靠,并取得了成功。释能降压技术是针对高压富水充填溶腔采取有计划、有目的的精确爆破揭示,从而释放溶腔所存储的能量,降低施工及运营过程中水土压力对隧道形成影响,之后,通过配套处治措施完成溶腔治理。
