<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， the effects of ultrasonic （US） pretreatment， free nitrous acid （FNA） pretreatment and ultrasonic-freenitrous acid （US-FNA） combined pretreatment on many aspects of sludge， including the dissolution of organic matter， dispersion of flocs， release of cellular contents， and methanogenic performance. The results showed that the primary impact of ultrasonic pretreatment was the dispersion of flocs and the dissolution of extracellular polymeric substances， whereas the pretreatment with free nitrous acid resulted in the release of cell content. In comparison to the no-treatment control， the generation of sludge methane exhibited a significant increase of 37.1%. Specifically， the ultrasonic group demonstrated a 1.07-fold increase， while the free nitrous acid group had a 1.08-fold rise. Nevertheless， the combined pretreatment of ultrasonic and free nitrous acid exhibited distinct roles， and no apparent synergistic impact was seen. The incorporation of free nitrous acid had the potential to decrease the rate of gas generation during the initial phase of anaerobic digestion of sludge. However， it did not exert a substantial impact on the overall gas output over time. The examination of microbial flora in sludge following fermentation revealed that the presence of free nitrous acid had a significant influence on the variety of microorganisms in the sludge.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， bamboo charcoal was prepared from waste generated during bamboo pulp preparation by phosphoric acid activation method， and then bamboo charcoal/BiOCl composite catalysts were subsequently synthesized via hydrothermal method， and the effects of dosage of bamboo charcoal and hydrothermal temperature on the photocatalytic properties of the composite catalysts were systematically investigated. The results showed that the bamboo charcoal retained the inherent pore structure of bamboo， and changing the dosage of bamboo charcoal could achieve the modulation of the morphology of the bamboo charcoal/BiOCl composite catalyst， which provided a good condition for pollutant adsorption. The pronounced interactions occurring between bamboo charcoal and BiOCl significantly improved the adsorption-photocatalytic performance and oxygen vacancy content of BiOCl， so that the efficiency of photogenerated electron transfer was enhanced and the photocatalytic degradation of the composite catalyst was optimised. The composite catalyst 5BC-140 observed at the hydrothermal temperature of 140 ℃ and bamboo charcoal dosage of 5% showed the optimal visible photocatalytic properties， with the removal rate of rhodamine B reaching 86.5% within 30 min， the one-mediated kinetic constant <i>k</i> being 4.2 times that of BiOCl， and excellent stability and recyclability.]]></description>

<link><![CDATA[http://zgzz.ijournals.cn/zgzzen/ch/reader/view_abstract.aspx?file_no=202407024&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[With the continuous advancement of the “dual carbon” strategy， the utilization of solid waste is increasingly emphasized. At present， the overall utilization rate of solid waste and added value of the products are relatively low. In recent years， the solid waste-based paper fillers have received widespread attention because the solid waste based paper fillers can not only alleviate environmental pollution issues but also substitute cellulose fiber raw materials， reduce paper production costs and improve paper properties to some extent. Therefore， using solid waste to prepare paper filler is undoubtedly an effective way to utilize solid waste comprehensively. This paper discussed the advantages and challenges of solid waste based-paper filler. The impacts of solid waste based-paper filler on the physical properties of paper were also analyzed based on preparation strategies and their physical and chemical properties. Finally， the development direction of solid waste based filler was also outlined.]]></description>
