“…More than 150 chemical compounds have been identified in swine manures (Cook et al 2007). However, traditional disposal with limited land pose severe environmental contamination such as pathogens, atmospheric methane, ammonia, phosphorus, malodorous and estrogenic compounds (Yang & Cicek 2008;Prado et al 2009). Cost-effective treatment of swine wastewater therefore remains a great challenge for environmental studies.…”

An upflow anaerobic sludge blanket (UASB) reactor was successfully established to treat swine wastewater. The bacterial structure and biodiversity of activated sludge in the anaerobic bioreactor were analyzed using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and amplified 16S rDNA restriction analysis (ARDRA). The UASB reactor was acclimatized with swine wastewater for a period of 36 days and exhibited an increase in daily COD removal rate up to 90% and methane production up to 9.5 L/day for an influent COD of 3,500 mg/L at the end of the start-up period. The reactor was then run continuously with an influent COD of 3,000-6,000 mg/L in the following two months of steady operation, reaching COD removal rate of 90-95% and methane production of 9.5-13.2 L/day respectively. The results of microbial community analysis showed a diversified and abundant bacterial structure and biodiversity during the start-up period, which then changed insignificantly in the steady operation period. The change patterns of the bacterial population function were similar to those of the bioreactor performance, indicating a close relationship between bacterial community structure and treatment efficiency.

“…In addition and in view of the comparison, an experiment was also carried out with activated sludge from a membrane bioreactor treatment plant. 4,5 It led, for both antibiotics, to higher biodegradation rates and residual CO 2 compared with those recorded with lab-scale activated sludge; while the level of antibiotic contamination of the activated www.interscience.wiley.com/jctb sludge from the pilot-plant membrane bioreactor (40 mg L −1 TOC - Table 4) was higher than that of the lab-scale activated sludge (0-20 mg L −1 TOC - Table 3). …”

“…2,3 Recently, membrane bioreactors have also been used successfully to treat swine wastewater. 4,5 The characteristics of wastewater may also vary; the influent can be constituted of fresh or stocked wastewater, fresh and stocked manure may also be mixed to enhance the influent carbon content, or manure can be mixed with other industrial wastewaters. These different configurations lead to a unique bacterial consortium constitutive of a specific activated sludge, even if similar macroscopic activated sludge behaviour is observed.…”

BACKGROUND: CO 2 -evolution tests (OECD 301-B), formerly known as modified Sturm tests, are commonly used for evaluation of the biodegradation potential of non-volatile molecules through measurement of the carbon dioxide produced. Extension of the modified Sturm test to evaluation of the toxicity of veterinary antibiotics, tetracycline and tylosine, on the biological treatment of swine wastewater was examined in this work.

“…Statistically, the recorded piggery wastewater discharged to the environment was more than 1.1×10 7 tons in 2014 [11]. Since these pollutants become heavy burdens to the environment, various biological methods have been developed, such as anaerobic bioreactors [12], membrane bioreactors [13], and upflow microaerobic sludge reactors [14]. Moreover, the sequencing batch reactor (SBR), owing to its characteristics of easy operation and high efficiency, is also widely used in the treatment of piggery wastewater [15][16][17].…”

This work evaluates the efficiency of ammonium removal from piggery wastewater using a sequencing batch reactor (SBR) inoculated with a newly isolated strain of Pseudomonas putida HJH1. The strain HJH1 not only could survive and remove up to 72.4 mg/L NO 2 --N under aerobic conditions, but it also has good performance for simultaneous nitrification and denitrification (SND) with no nitrite accumulation. The SBR system was able to consistently remove: 1) 76.4-100% ammonium nitrogen and 71.4-100% COD from artificial wastewater in stage 1, and 2) 89.2-99.1% ammonium nitrogen and 82.4-100% COD from piggery wastewater in stage 2. During the whole operation, the strain HJH1 predominated in the SBR all the time to function together with other bacteria. Results indicated that the SBR system inoculated with Pseudomonas putida HJH1 can efficiently remove ammonium nitrogen from piggery wastewater, thereby having potential applications for future nitrogen removal.
