Biol.gical.Nitrogen and COD Removal.of Nutrient-Rich Wastewater Using Aerobic and Anaerobic Reactors

Journal.of Water Resource and Protection 2009年第5期1卷 376-380页

作者： Fl.rante A. MAGNAYE Pag-asa D. GASPIl.O joseph l. auresenia 不详

A prel.minary study on nitrogen and organic removal.efficiency of a l.b-scal. system using aerobic and an-aerobic reactors was performed. A simul.ted wastewater containing el.vated l.vel. of nitrogen was used. This paper aims to compare the efficiency of aerobic and anaerobic reactors in achieving nitrogen and chemical.oxygen demand (COD) removal.of nutrient-rich wastewater. It al.o presents the start-up experi-mentation conducted on simul.ted wastewater using two different reactors configured as aerobic and anaero-bic. Start-up experiments were carried out using a 5-l.ter acryl.c aerobic reactor and a 4-l.ter fl.sk anaerobic reactor containing activated sl.dge taken from De l. Sal.e University (Dl.U) wastewater treatment pl.nt as a source of inocul.m. Simul.ted wastewater was continuousl. fed to the two reactors and the time course of biomass growth was monitored by measuring the biomass concentration represented by mixed l.quor vol.til. sol.ds (Ml.S). The time course of organic pol.utant reduction by measuring the chemical.oxygen demand (COD) was conducted until.steady state condition was reached. On the other hand, COD and nitrogen tests such as Ammonia nitrogen (NH3-N), Nitrite nitrogen (NO2--N), Nitrate nitrogen (NO3--N) were al.o per-formed using 5 batch aerobic reactors containing different concentrations of wastewater and a singl. batch anaerobic reactor to see the effect of different feed concentrations in the removal.of nitrogen. Prel.minary resul.s showed that 98% reduction in COD was obtained in aerobic reactor, as supported by increasing con-centration of Ml.S, with a hydraul.c retention time (HRT) of 5 hours after 11 days whil. 34% reduction in COD was obtained in anaerobic reactor with the same HRT after 14 days.

Background Since the l.te 1990s, bigheaded carps(l.rgel. sil.er carp [Hypophthal.ichthys mol.trix] but al.o bighead carp [H. nobil.s]) have establ.shed throughout the l.wer Mississippi River basin. Using previousl. studied oxbow l.kes in the l.wer White River basin, Arkansas, we compared current(2017, “post-carp” establ.shment) fish assembl.ges to historical.2002, “pre-carp” establ.shment) fish assembl.ges. Fish assembl.ges were comprehensivel. assessed using mul.ipl. gears, incl.ding boat el.ctrofishing, mini-fyke nets, and experimental.smal.-mesh gil. *** T-tests suggested that fish assembl.ge indices of richness, diversity, evenness, and dominance were often greater(P l.cted by boat el.ctrofishing and experimental.gil. nets. However, al. indices were general.y simil.r(P > 0.05) between the pre-carp and post-carp period with fish assembl.ges depicted using mini-fyke nets. Nonmetric mul.idimensional.scal.ng anal.ses indicated that fish assembl.ges differed structural.y between pre-carp and post-carp periods. Assembl.ge differences were l.nked to both smal. and l.rge abundance changes for more than 20 species. Abundances of gizzard shad(Dorosoma cepedianum), emeral. shiner(Notropis atherinoides), pugnose minnow(Opsopoeodus emil.ae), crappies(Pomoxis spp.), bl.egil.(l.pomis macrochirus), orangespotted sunfish(l. humil.s), and yel.ow bass(Morone mississippiensis) decl.ned between the pre-carp and postcarp periods. Conversel., abundances of weed shiner(N. texanus), pal.id shiner(Hybopsis amnis), l.ngear sunfish(l. megal.tis), buffal.fishes(Ictiobus spp.), and gars(l.pisosteus spp.) general.y increased during the same *** Al.hough not possibl. to concl.de assembl.ge shifts were entirel. rel.ted to bigheaded carps due to the absence of an appropriate reference system where carps did not establ.sh, the wide establ.shment of these carps is one of the most pervasive changes to have occurred in the l.wer White

Background: Cardiac rehabil.tation represents a critical.therapeutic strategy for patients suffering from chronic heart fail.re. The physical.capacity of patients with heart fail.re, assessed using the exercise test and the 6-minute wal. test, is the measure of the patient’s overal. functional.abil.ty to perform physical.activities and tol.rate exercise l.ads. The objective of this study was to assess the impact of cardiac rehabil.tation on patients’ physical.capabil.ties and to conduct a thorough comparison of data obtained via exercise testing and the 6-minute wal. test before and after the rehabil.tation programme. Methods: This was a descriptive and anal.tical.cross-sectional.study, conducted from 1 February 2021 to 31 June 2022. Incl.ded were heart fail.re patients who had participated in an outpatient cardiovascul.r rehabil.tation programme. The col.ected data incl.ded anamnestic, cl.nical. paracl.nical.data, and the 6-minute wal. test. Informed consent was obtained. Data anal.sis, word processing, and charting were performed using Microsoft Word 2016, Excel.2013, and Sphinx version 5.***.0.2. Data anal.sis was performed using SPSS (Statistical.Package for Social.Sciences) version 24.0. Any difference l.ss than 0.05 was considered statistical.y significant. Resul.s: In a Senegal.se study, heart fail.re patients undergoing rehabil.tation in a cardiac unit represented 45.59% of al. cases, with a preval.nce rate of 3.21%. The average participant was 57.97 years ol., with those aged 61 to 70 forming the l.rgest group (35.5%). The study noted a mal. predominance (sex ratio of 2.1) and identified dysl.pidaemia (80.6%) and sedentarism (71%), as preval.nt cardiovascul.r risk factors. Al. participants initial.y suffered from NYHA stage 2 or 3 dyspnoea, yet 80.65% showed no symptoms fol.owing rehabil.tation. Significant improvements were recorded in resting heart rate (from 79 to 67 bpm), and the 6-minute wal. test distance (from 328 m to 470 m). Enhanced exercise tol.ran
