微电解—吸附用于海水除藻试验研究

Study on Algae Removal in Seawater by Micro-electrolysis Adsorption

该研究以含藻海水为研究对象,利用电气石填料构造的三维电极来研究微电解—吸附协同除藻效果,主要研究了电气石投加量、电流密度、极板间距、初始含藻量对除藻效果的影响,并对电气石的表面形貌变化进行了考察。研究结果表明,在一定范围内,除藻率随着电气石投加量和电流密度的增加而上升;极板间距过大或过小均不利于除藻,需保持适当的距离;除藻率随着初始含藻量的增加而降低;电气石处于“吸附—降解—吸附”动态平衡中,电气石吸附以表面吸附为主。在实验条件下,电气石的投加使得除藻率提高约15%,电解时间缩短约20%,最佳极板间距为2 cm^3 cm,电气石最佳投加量为100 g。

In this study,algae-containing seawater was used as the research object,and the three-dimensional electrode constructed with tourmaline was used to research the effect of micro-electrolysis adsorption on algae removal.This work mainly researched the effect of tourmaline dosage,current density,plate spacing,and initial algae content on algae removal,and the surface morphology of tourmaline was also investigated.The results showed that within a certain range,the algae removal rate increased with the increase of tourmaline dosage and current density;larger or too smaller electrode spacing was not conducive to algae removal,and an appropriate distance must be maintained;the algae removal rate decreased with the increase of initial algae content,the tourmaline was in the“adsorption-degradation-adsorption”dynamic equilibrium,and the adsorption of tourmaline was mainly surface adsorption.Under the condition of this experiment,the addition of tourmaline increased the algae removal rate by about 15%,the electrolysis time was shortened by about 20%,the optimal electrode plate spacing was 2 cm^3 cm,and the optimal amount of tourmaline was 100 g.
