摘要

研究了草酸铁诱导的太阳能光fenton工艺处理天然胶乳废水的效果。在实验室规模的太阳能-芬顿塞流挡板反应器中进行了反应。采用中心复合实验设计进行优化研究，包括pH、H2O2、Fe2+和草酸的初始浓度。通过对COD去除率的分析，确定了光催化降解效率。在pH = 4、Fe2+ = 1.3 g/L、草酸= 2.25 g/L、H2O2 = 82.5 g/L、太阳照射时间为6 h的最佳条件下，COD去除率为99%。采用草酸铁诱导的太阳光- fenton工艺处理乳胶废水，可降解率在2小时内由0.36提高到0.7。据估计，每天处理5立方米乳胶废水的草酸铁诱导太阳能光- fenton氧化的总成本为85美元/立方米。

Ferrioxalate-induced solar photo-Fenton treatment of natural rubber latex wastewaters

This study evaluated a ferrioxalate-induced solar photo-Fenton process for natural rubber latex wastewater treatment. The reaction was carried out in a laboratory scale solar photo-Fenton plug flow baffle reactor. An optimization study was performed using a central composite experimental design including the following variables: pH, initial concentrations of H2O2, Fe2+, and oxalic acid. The photocatalytic degradation efficiency was determined by the analysis of COD removal. Under the optimum conditions of pH = 4, Fe2+ = 1.3 g/L, oxalic acid = 2.25 g/L, H2O2 = 82.5 g/L, and solar irradiation time of 6 hours, the COD removal efficiency was 99%. Treatment of latex wastewater by ferrioxalate-induced solar photo-Fenton process increased biodegradability ratio from 0.36 to 0.7 in 2 hours. The overall cost of ferrioxalate-induced solar photo-Fenton oxidation for the treatment of 5 m3 of latex wastewater per day was estimated to be US $85/m3.

期刊介绍： The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas: Impact of current and emerging contaminants on aquatic ecosystems Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk) Conservation and protection of aquatic environments Responsible resource development and water quality (mining, forestry, hydropower, oil and gas) Drinking water, wastewater and stormwater treatment technologies and strategies Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality Industrial water quality Used water: Reuse and resource recovery Groundwater quality (management, remediation, fracking, legacy contaminants) Assessment of surface and subsurface water quality Regulations, economics, strategies and policies related to water quality Social science issues in relation to water quality Water quality in remote areas Water quality in cold climates The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
