“…Electrochemical treatment, another popular LWW management approach that has attracted considerable attention in recent years. Among different electrochemical treatment technologies, electrocoagulation is most widely used due to its simplicity and ability to treat a wide array of pollutants including emerging contaminants present in LWW [ 138 , [143] , [144] , [145] , [146] , [147] ]. Regardless of electrode materials, parameters such as current density, pH, treatment time, electrolyte concentration, and interelectrode gaps are important for the successful and efficacious operation of electrocoagulation processes [ [148] , [149] , [150] , [151] ].…”

“…That is, they generate hydroxyl radicals (•OH) using various catalysts like ozone, chlorine oxidants, and hydrogen peroxide [5] to convert refractory organics into easily degradable organics or completely oxidize them into CO 2 and H 2 O. AOP have unique advantages in the treatment of swine wastewater containing high concentrations of organic matter (including most refractory organic matter), which can rapidly promote the mineralization and decomposition of organic matter in wastewater [1] and may be the most suitable method for removing refractory organic matter in swine wastewater [4]. Currently, AOP that have been widely studied and applied can be divided into Fenton, ozone catalytic oxidation, electrochemical oxidation [37], UV/hydrogen peroxide, photocatalytic oxidation, and so on.…”

Swine wastewater contains large amounts of organic matter, nutrients, toxic metal elements, and antibiotics. If it is directly discharged or not properly treated, it poses a significant threat to the environment and human health. Currently, the management of swine wastewater has become a focus of social attention, and it adopts a dual-track parallel model of standard discharge supplemented by resource utilization. If treated properly, it can achieve the recycling of water resources and promote the effective recovery of resources. Based on the pollution characteristics of swine wastewater, this paper analyzes its impact on the environment, society, and the economy in detail and expounds on the research progress of swine wastewater treatment technology. From the perspective of resource utilization and recycling of anaerobic digestion liquid (biogas slurry) from swine wastewater and the carrying capacity of the soil environment and cumulative ecological environmental risks, this study explores new development trends and application prospects for swine wastewater treatment technology.

“…If Fe 2+ is to be produced in the cell, a sacrificial anode made of iron or stainless steel is used; if H2O2 is to be produced, air or oxygen is introduced into the cell, usually using a graphite or carbon cathode. If inert electrodes with high catalytic activity are used, both reagents can be added externally (Reza & Chen, 2022;Yao et al, 2022). In this study, Fe 2+ is produced in situ while H2O2 is added from outside.…”

Waste water containing reactive textile dyes constitutes an important environmental problem as they are permanent and dangerous. The Electro-Fenton (EF) method is promising as an effective technique for the degradation of organic materials such as dyestuffs. In this study, the optimization of effective variables in the removal of reactive yellow 145 azo textile dye by the EF using response surface methodology (RSM) was investigated. Central composite design (CCD) was used to study the combined effects of key parameters such as voltage (2.5–12.5 V), H2O2 addition (0.1–1.3 mL), pH (1.75–4.75), electrode spacing (0.25–3.25 cm), and treatment time (25–85 min). The optimum values of the variables to ensure the highest dye removal efficiency (approx. 93%) with the lowest energy consumption (approx. 3.4 Wh/L) are approximately 9.4 V voltage, pH 3.7, 2.5 cm electrode range, 1 mL H2O2 addition, and a 40-minute treatment time. ANOVA analysis of the predicted quadratic polynomial model showed a regression coefficient value of approximately 0.97 for both objective functions; this highlights the applicability of the model for navigating the design space. Simultaneous optimization of process parameters using RSM was achieved with a low number of experiments.
