絮凝动态膜和二氧化氯协同优化处理压载水机理研究

Single method such as physical method, chemical method or biological method for ballast water treatment technology is difficult to defend alien biological invasion.Up to now, there is not a way to satisfy simultaneously safe, economy, efficiency, practicability and environment protection five criteria required in the IMO ballast water treatment. It is the trend for ballast water treatment research with efficient composite method. Based on the flocculation dynamic membrane filtration technology and chlorine dioxide disinfection technology research early, the project proposes a new collaborative optimization method based on flocculation dynamic membrane and chlorine dioxide technology according to the physical and chemical properties of sediments and the microbial diversity on the ballast water treatment.In the project,we firstly construct the flocculation dynamic membrane filtration ballast hydrodynamic model through fractal theoretical and system mathematical simulation. Secondly, by means of fuzzy comprehensive evaluation and multi-level analysis, we optimize and validate the coordination mechanism of the flocculation dynamic membrane and chlorine dioxide techology. Finally, we verify the proposed method by the experimental platform. The project mainly solves three scientific problems on revealing the flocculation dynamic membrane filtration ballast water mechanism, clarifing chlorine dioxide oxidation processing the ballast water mechanism and contructing the flocculation dynamic membrane filtration technology with chlorine dioxide oxidation technology collaborative optimization mechanism. In this way, we can provide a new approach and scientific basis to high efficiency ballast water treatment.

基于单一的物理法、化学法或生物法等压载水处理技术均难以有效解决生物入侵问题，目前没有一种方法能同时满足 IMO 关于压载水处理的安全、经济、有效、实用且环境容许等五项标准，研究高效复合处理压载水方法大势所趋。本项目在前期絮凝动态膜过滤技术和二氧化氯消毒技术的研究基础上，针对压载水微生物多样性和沉积物物化性质，提出絮凝动态膜和二氧化氯协同优化处理压载水方法。首先通过分形理论和系统数学仿真，构建絮凝动态膜过滤处理压载水动力学模型；然后采用模糊综合评判法和多层次分析法，优化及验证絮凝动态膜和二氧化氯协同机制；最后通过实验平台对提出的方法进行验证。本项目重点揭示絮凝动态膜过滤处理压载水机理、阐明二氧化氯处理压载水机理、优化絮凝动态膜过滤与二氧化氯协同处理压载水机制等三个科学问题，为高效压载水处理技术提供新思路和科学依据。
