“…La baja diversidad registrada en la zona media del río posiblemente se debe a que varios tributarios (caños o arroyos) están afectados ambientalmente, y en la corriente principal hay vertimientos de aguas residuales (80 %), valores altos en bicarbonatos (Torres-Mora et 2015), valores bajos en oxígeno disuelto, variable fundamental para la biota (Mendoza et al, 2019) que afectan la composición y abundancia de organismos (Aguilera-Giraldo y Vásquez-Ramos, 2019). También se registraron los valores más altos en tensoactivos aniónicos, fuente importante de deterioro de calidad de agua, que junto a los ortofosfatos (>2,22 mg/LPO4 3-) asociados a contaminación por descargas domésticas y agrícolas señalan alta contaminación y eutrofización del sistema (Gómez-Anaya et al, 2017;Solari et al, 2013).…”

El río Ocoa es importante para el desarrollo del municipio de Villavicencio, pero esta sometido a diferentes actividades antropogénicas a lo largo del cauce que afectan la diversidad de insectos acuáticos bioindicadores. El objetivo de esta investigación fue determinar la respuesta de la diversidad funcional y taxonómica de insectos acuáticos (EPT) al uso del suelo en el río Ocoa. Se tomaron muestras de agua para la medición de 19 variables fisicoquímicas y bacteriológicas ex situ en 12 estaciones con diferentes usos del suelo (urbano e industrial, agricultura, natural, piscicultura, ganadería) y los organismos se recolectaron con red Surber. Se determinaron hasta género y se consignaron sus respectivos rasgos funcionales. Se emplearon los números efectivos de especies, índices de diversidad funcional, análisis de redundancia y de RLQ. Los ensamblajes estuvieron dominados por los géneros Smicridea (Trichoptera), Lumahyphes y Americabaetis (Ephemeroptera); y los rasgos funcionales frecuentes correspondieron a desarrollo lento, respiración por branquias, cuerpos blandos y medianos no aerodinámicos con hábito de agarrarse. Las estaciones de la zona media del río, correspondientes al uso de suelo urbano e industrial, presentaron baja a ninguna diversidad taxonómica y funcional. Los rasgos funcionales presentaron características asociadas al tipo de sustrato; los hábitos tróficos se relacionaron principalmente con materia orgánica (gruesa y fina). En contraste las estaciones de la zona alta y baja presentaron los mayores valores de diversidad taxonómica y funcional, cuyas estaciones se caracterizaron por uso del suelo natural, ganadería y agricultura.

“…After the preliminary experiments, the ozone flow rate was set at 0.3 L min À1 . Subsequently, the effects of initial pH (2)(3)(4)(5)(6)(7)(8), ozone flow rate (0-0.5 L min À1 ), Fe 0 dosage (0-70 g L À1 ), stirring speed (0-400 rpm), reaction temperature (8-80 C), and reaction time (0-60 min) on the COD removal were investigated, respectively. In addition, before the reaction temperature was investigated, all the tests were performed at room temperature.…”

“…Hence, Fe 3þ ions were generated quickly and precipitated in the solution. Fe 3þ precipitated as FeOOH and Fe(OH) 3 when the pH reached 7.92. Although these precipitates could also promote the mass transfer rate, the catalytic reaction was impaired because of the high pH level.…”

“…However, in the second stage (around 20-60 min), when a large number of H þ ions were consumed in the fast oxidation process and the H þ generation decreased, the pH value increased quickly to around 6-8. Under this pH condition, most of the ZVI was transformed and precipitated as Fe(OH) 3 . Thus, under different conditions, the reaction might proceed through another mechanism.…”

“…[2] If the antibiotic production wastewater is discharged into the environment without appropriate treatment, it will be extremely detrimental to the ecosystem and public health. [3,4] Effluents from pharmaceutical factories are generally subjected to biological treatment processes. However, they still contain several non-antibiotic refractory or biologically inhibitory organic compounds.…”

In this study, ozone/zero‐valent iron (ZVI) process is investigated to treat the refractory noxious antibiotic production wastewater. Effects of reaction conditions such as initial pH (2.5–8), ozone flow rate (0–0.5 L min−1), Fe0 dosage (0–7 g L−1), stirring speed (0–400 rpm), temperature (8–80 °C), and reaction time (0–60 min) on biochemical oxygen demand after five days (BOD5), chemical oxygen demand (COD) removal are studied, respectively. The results showed that high COD removal (79.9%) and BOD5/COD ratio (0.36) are obtained under the optimal conditions (initial pH 2.5, Fe0 dosage = 60 g L−1, ozone flow rate = 0.25 L min−1, reaction temperature = 30 °C, stirring speed = 300 rpm, reaction time = 60 min). The results indicate that refractory noxious compositions can be transferred and decomposed by the ozone/ZVI process dramatically. In addition, three control experiments (i.e., air/ZVI process, ZVI process, and ozone process) are performed to confirm the superiority of the ozone/ZVI process. Moreover, the degradation process is analyzed by UV–vis, Fourier‐transform infrared (FTIR), and excitation‐emission matrix (EEM) fluorescence spectroscopies. Therefore, the ozone/ZVI process is a potential and effective method for the advanced treatment of antibiotic production wastewater.

Introduction: The River Tambo basin is one of the main hydrographic systems of the Peruvian western watershed, being a source of development for agriculture, agroindustry, livestock, and domestic use in the Tambo Valley and Arequipa City. Objective: To analyze the structure of macroinvertebrates in River Tambo, Perú and assess the water quality through this community. Methods: Five sampling events were conducted between December 2018 and November 2019 in 12 stations, using a Surber net (500 μm). Macroinvertebrates were identified at a family level. To assess community structure, richness, Simpson’s dominance index (D), Pielou’s evenness (J’), and true diversity of order 1 were determined. A nMDS based on the Bray-Curtis index was used to evaluate dissimilarity. To check for differences in community structure, ANOSIM and two-way MANOVA were used. SIMPER was used to establish family contribution to sample similarity. Relations between physicochemical and biological variables were determined by CCA. ABI index was applied to assess ecological quality. Results: 32 families were recognized, being the most abundant: Baetidae, Chironomidae, Leptohyphidae, Simuliidae, Hydroptilidae, and Elmidae. The middle and low zones of the basin showed the highest and lowest diversity respectively. There were significant differences (P < 0.05) in the community structure indices among the 12 stations differed. There was a higher similarity among the 12 stations in December. ABI scores increased from the low to the middle part of the river, which showed the highest ecological quality. Conclusion: Macroinvertebrate communities from River Tambo reflect ecosystem conditions. Environments impacted by human activities show lower diversity and ecological quality, due to the structure, habitat, and water quality of the river being altered.
