摘要
有害藻华的频繁爆发会对水生态、水环境和人类健康构成严重威胁,传统的除藻技术存在一定的局限性,而光电协同催化是一种光催化和电氧化高效结合的新型技术,可弥补传统除藻技术的不足。本文以小球藻为模式生物,采用光电协同催化技术进行藻类去除试验。考察了FeCo_(2)O_(4)不同掺杂比、电流密度、电解质浓度、催化剂投加量和藻生物量对叶绿素a去除率的影响。结果表明:电流密度越高、电解质浓度越大、催化剂投加量越多和藻生物量越低时除藻效果最好。当电流密度为2.0 mA/cm^(2)、电解质浓度为0.10 M和催化剂投加量为0.30 g时,对藻生物量(6.0×10^(6)cells/mL)的去除率达到93.71%。因此,本研究可以为水体富营养化和藻类爆发的管理和控制提供科学依据。
The frequent outbreaks of harmful algal blooms pose serious threats to aquatic ecosystems,water environments,and human health.Traditional algae removal technologies have certain limitations,whereas photo-electric synergistic,as a novel technology that efficiently combines photocatalysis with electrooxidation,can compensate for the deficiencies of traditional algae removal methods.We take Chlorella vulgaris as a model organism and uses photoelectric synergistic catalytic technology for algal removal experiments.We investigated the influence of different doping ratios of FeCo_(2)O_(4),current density,electrolyte concentration,catalyst dosage and algal biomass on the chlorophyll a removal rate.The results showed that the best algal removal effect was achieved at higher current density,higher electrolyte concentration,higher catalyst dosage and lower algal biomass.When the current density is 2.0 mA/cm^(2),the electrolyte concentration is 0.10 M,and the catalyst dosage is 0.30 g,the removal rate of algal biomass(6.0×10^(6)cells/mL)reaches 93.71%.Therefore,our study can provide scientific basis for the management and control of water eutrophication and algae outbreak.
