“…Comparing all R 2 data, the largest R 2 value for each antibiotic appeared in group 1, which was a control sample with no antibiotic addition and the balanced state in the reactor had not been disrupted. Previous researchers found similar results when fitting the degradation kinetic models of solid and liquid antibiotics [25]. This result could be due to TCs existing in a form that can be dissolved in the liquid phase and adsorbed in the solid phase.…”

Tetracycline antibiotics (TCs) are a common type of antibiotic found in swine wastewater. Oxytetracycline (OTC) is a significant type of TC. This study mainly examined the influence of OTC on high-temperature anaerobic digestion by adding OTC to collections of swine wastewater at different times during the digestion process. The results showed that high-temperature anaerobic digestion was suitable for the removal of TCs, with an 87% OTC removal efficiency achieved by day 20. Additionally, OTC added from external sources was found to inhibit the chlortetracycline degradation process and affect the first-order degradation kinetic model of TCs. Complexation reactions were the main ways in which OTC affected the heavy metal content of the water. The exogenous addition of OTC was found to inhibit the activity of some digester microbial strains, reduce the proportion of dominant strains, such as MBA03, and kill certain specific strains. This performance alteration was most obvious when OTC was added in the middle of the reaction.

“…However, the treated wastewater and sludge residues could still cause harm to the surrounding environment [ 46 ]. Under the conditions of 1.38–2.16 kg chemical oxygen demand (COD)/m 3 ·d, an operating temperature of 37 ± 1 °C, and an HRT of 16 d, the TC and QN removal rates from swine wastewater by AD have been reported to be 65% and 85%, respectively [ 38 ].…”

Antibiotic pollution has become an increasingly serious issue due to the extensive application of antibiotics, their resistance to removal, and the harmful effects on aquatic environments and humans. Breeding wastewater is one of the most important sources of antibiotics in the aquatic environment because of the undeveloped treatment systems in breeding farms. It is imperative to establish an effective antibiotic removal process for breeding wastewater. This paper reviews the treatment methods used to remove antibiotics from breeding wastewater. The mechanisms and removal efficiency of constructed wetlands, biological treatments, advanced oxidation processes (AOPs), membrane technology, and combined treatments are explained in detail, and the advantages and disadvantages of the various treatment methods are compared and analyzed. Constructed wetlands have high removal rates for sulfonamide (SM), tetracycline (TC), and quinolone (QN). The antibiotic removal efficiency of biological treatment methods is affected by various processes and environmental factors, whereas AOPs and combined treatment methods have better antibiotic removal effects. Although it has broad application prospects, the application of membrane technology for the treatment of antibiotics in breeding wastewater needs further research.

“…Annual antibiotic consumption in China has reached 162,000 tons in 2013, accounting for ~50% of global usage [1]. Fifty-two percent of the antibiotics are used in animal farms for the prevention and treatment of diseases and to increase production [2][3][4][5]. The majority of antibiotics (30%-90%), in the form of raw substances or their metabolites, are released back into the natural environment through animal faeces and urine [6][7][8].…”

“…The treatment of antibiotics in animal wastewater is essential for protecting our ecosystem. Animal farms are commonly located far away from the municipal sewage system, which leads to the use of simple treatment units, such as anaerobic digestion (AD), constructed wetlands or lagoons, to treat the animal wastewater [5,15,16]. The storage of animal wastewater in a tank for up to several months is also common.…”
