Nano-Fe2O3/goldmine complex was obtained by chemical coprecipitation on the surface of goldmine waste-solid. And its application as the heterogeneous catalyst in Fenton-like advanced oxidation processes (AOPs) was discussed for the degradation of dyeing wastewater. It was found that advanced oxidation processes play an important role to the removal of dyeing wastewater. And the best removal rate of 15400mg/L dyeing wastewater reached up to 63.1% with the presence of 50g/L dosage of nano-Fe2O3/goldmine complex and 50mL/L concentration of H2O2at 50°C with pH=3.

Phosphorus is one of the main pollutants in glyphosate wastewater. In order to remove the phosphorus in the effluent, two units including CaO precipitation and advanced oxidation processes (AOPs) were used to degrade inorganic phosphate and organic phosphorus in the wastewater. It is found that in the precipitation process the removal rate of TP is 79% when 1g CaO is added to 100ml glyphosate wastewater, while the removal rate of TP is almost 99% when advanced oxidation processes are implemented after the second disposal unit.

Degradation of dye wastewater was studied by using nanoferrous modified bentonite as the heterogeneous catalyst for a Fenton-like oxidation. By comparing the effect of homogeneous Fenton reactions as well as heterogeneous Fenton-like process for nanomodified bentonite, it is found that the advanced oxidation processes assisted by nanoferrous/bentonite complexes exhibit the stronger degradation capacity. And the removal rate of Fenton-like reaction increased from 23.6% to 75.5% when the ferrous concentration increasing from 20 to 100mmol/L. Being compared with homogeneous Fenton reactions, 20% increased degradation efficiencies is obtained by Fenton-like oxidation process for nanomodified bentonite under 6g nanoferrous/bentonite complexes in 100mL dye wastewater.

Polyvinyl alcohol (PVA) is an emerging pollutant commonly found in industrial wastewater, owing to its extensive usage as an additive in the manufacturing industry. PVA’s popularity has made wastewater treatment technologies for PVA degradation a popular research topic in industrial wastewater treatment. Although many PVA degradation technologies are studied in bench-scale processes, recent advancements in process optimization and control of wastewater treatment technologies such as advanced oxidation processes (AOPs) show the feasibility of these processes by monitoring and controlling processes to meet desired regulatory standards. These wastewater treatment technologies exhibit complex reaction mechanisms leading to nonlinear and nonstationary behavior related to variability in operational conditions. Thus, black-box dynamic modeling is a promising tool for designing control schemes since dynamic modeling is more complicated in terms of first principles and reaction mechanisms. This study seeks to provide a survey of process control methods via a comprehensive review focusing on PVA degradation methods, including biological and advanced oxidation processes, along with their reaction mechanisms, control-oriented dynamic modeling (i.e., state-space, transfer function, and artificial neural network modeling), and control strategies (i.e., proportional-integral-derivative control and predictive control) associated with wastewater treatment technologies utilized for PVA degradation.
