This work proposed an ozonation enhanced acid leaching strategy, and typical operating parameters were optimized.

Two novel approaches are further employed to enhance the leaching rates. It was found that the coupling of UV radiation did not play a synergistic role for metal leaching, while it increased rapidly when H<sub>2</sub>O<sub>2</sub> was added into the leaching system, though the enhancement effect was not continuous. In addition, ball milling pretreatment and ozone micro-nano bubbles both greatly improved the metal leaching rates from chalcopyrite. The leaching rate of Cu can reach to 86.5 % after ball milling, and the concentrations of Fe and Cu in the leaching solution with O<sub>3</sub> micro-nano bubbles increased by 7.7 and 10.0 times than those with common O<sub>3</sub> bubbles.

Different traditional methods have been applied to treat hospital wastewater (HW). Recently, hybrid processes, such as electrocoagulation (EC) with the electro-Fenton (EF) process, have been found to outperform traditional methods in terms of their high removal rate, low sludge generation and energy consumption and environmental sustainability. Herein, a combined EF process integrated with EC was successfully applied to reduce the chemical O demand (COD) of HW. A batch tubular electrochemical reactor composed of a microporous graphite air diffusion cathode and a hollow cylinder Al anode was used as a new design to remove pollutants from HW. Response surface methodology was adopted to explore the effects of operating factors, which were represented by current density, Fe<sup>2+</sup> concentration and time, on COD removal and identify their interactions. The best operating conditions were a current density of 20 mA/cm<sup>2</sup>, an Fe<sup>2+</sup> concentration of 6 mM and a reaction time of 63 min. These conditions yielded a COD removal efficiency (RE %) of 93.5 % with an energy consumption of 18.325 kWh/kg COD. Time had the main effect on the RE % due to the synergistic effect of EC and EF. The hybrid system had higher efficiency and lower energy consumption and sludge production than individual EC or EF. Therefore, combining EC with EF could be a promising approach for the treatment of HW.</div></div>","PeriodicalId":9929,"journal":{"name":"Chemical Engineering and Processing - Process Intensification","volume":"212 ","pages":"Article 110258"},"PeriodicalIF":3.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper puts forward a numerical investigation of the supersonic air flow inside a Laval nozzle for different designs of both convergent and divergent sections. The results have shown that the flow is more affected by the divergent geometry than by the convergent design. Disturbances on the flow were observed when a linear shape is used in the later part. The disturbances formed when a linear divergent section were progressively reduced as the length of the constant area portion increases. By using an Arina divergent section, smaller velocity gradients were observed, which can be a positive aspect for phase separation during the condensation process.
