摘要

为原位治理湖库等封闭水域的富营养化水体,提出了一种移动式水质净化平台治理新技术。移动式水质净化平台由水质净化单元(吸附单元、微孔曝气单元和微电流电解单元)、指令控制单元、水质在线检测单元和动力推进单元等组成。平台在水中移动过程中,通过微孔曝气单元和吸附单元的脱氮除磷,微电流电解抑藻来实现水体中过量营养盐削减和有害藻类防控的双重目的。针对移动式水质净化平台各单元功能要求,利用优选的吸附材料、曝气方式和电极材料,通过移动条件下的吸附、微孔曝气和微电流电解实验研究,获得最佳的吸附材料用量、原位吸附时间、曝气强度、电流密度、电解时间等技术参数。最后,根据实验结果,对进一步提高移动式水质净化平台的效率、平台运行管理等方面进行展望。移动式水质净化平台是一种富营养化水体治理的新技术,有望为富营养化水体营养盐削减和藻类水华防治提供新的解决方案。

Abstract

A mobile water purification platform for in-situ treatment of lake and reservoir eutrophication water is proposed in this paper. This platform is composed of water purification unit (mainly including adsorption unit, fine bubble aerator and micro-current electrolysis unit) and instruction control unit, water quality on-line detection unit and propulsion unit. Excessive nutrient is reduced and harmful algal blooms are controlled by removing nitrogen and phosphorus through adsorption unit and fine bubble aerator and inhibiting algal through micro-current electrolysis unit. The optimal dosage of adsorption material, in-situ adsorption time, aeration intensity, current density, electrolytic time and other technical parameters are obtained by experiments of adsorption, micro-porous aeration and micro current electrolysis using high-performance adsorbents, optimal aeration approach and electrode material. Finally, ways to improve the water purification performance and enhance the operation management of this platform are discussed according to the experimental results and subsequent practical applications. Overall, this platform is a new and effective technology of eutrophication treatment, and will provide solutions for the prevention and control of nutrient reduction and algae blooms.

Key words： eutrophication water; mobile platform of water purification; micro-current electrolysis; fine bubble aerator; adsorption
