摘要

本研究的主要目的是在UV-A （600 W）照射下，采用氯化铁（FeCl3）混凝-絮凝结合多相光催化的方法对含有机污染物的奶酪废水进行处理效果评价。混凝-絮凝实验结果表明，混凝剂投加量为0.4 Fe3+ g L−1时，混凝剂对浊度、化学需氧量（COD）和生物需氧量（BOD5）的去除率分别为98.83%、49.23%和40.58%。随后，在pH(4)条件下，将tio2基光催化工艺应用于预处理后的奶酪废水，将COD的去除率从3179.26 mg O2 L−1提高到437.47 mg O2 L−1，去除率为86.24%；TiO2 (0.5gL−1)，辐照时间16 h。最后，通过番茄、黄瓜和苜蓿种子发芽/根伸长试验，检测奶酪废水样品在处理前后的植物毒性。实验结果表明，该工艺处理后的奶酪废水毒性显著降低。这些发现令人鼓舞，并支持将处理过的奶酪废水作为灌溉的额外淡水来源的可能性。

Treatment of Cheese Wastewater by Coagulation-Flocculation Coupled with Heterogeneous Photocatalysis Using a New Synthesized TiO2 Anatase: Treatment Efficiency and Phytotoxicity evaluation

The main objective of this research was to evaluate the treatment efficiency of cheese wastewater containing organic pollutants by combining coagulation-flocculation with ferric chloride (FeCl₃) and heterogeneous photocatalysis in which a new synthesized TiO₂ was used under UV-A (600 W) irradiation. Coagulation-flocculation experiments showed that the removal of turbidity, chemical oxygen demand (COD), and biological oxygen demand (BOD₅) were 98.83, 49.23, and 40.58%, respectively, at a coagulant dose of 0.4 Fe³⁺ g L⁻¹. Thereafter, the application of TiO₂-based photocatalysis process to the pretreated cheese wastewater improved the COD reduction from 3179.26 mg O₂ L⁻¹ to 437.47 mg O₂ L⁻¹ with a removal percentage of 86.24%, using the optimized conditions given by pH (4); TiO₂ (0.5gL⁻¹), and 16 h for irradiation time. Finally, cheese wastewater samples were examined for their phytotoxicity, before and after treatments, through seed germination/root elongation tests using tomato, cucumber, and alfalfa seeds. The experimental results showed a significant decrease in toxicity of the treated cheese wastewater using the combined process. These findings are encouraging and support the possible use of treated cheese wastewater as an additional freshwater source for irrigation.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
