“…However, no significant increments were detected at 800 • C after H 2 O addition. The existence of competition between sulfur and phosphorous has been verified by previous researches [43,44]. Besides faster adsorption of phosphorous brought by H 2 O, the reaction between MgO or CaO and SO 2 was simultaneously facilitated [45].…”

Sewage sludge (SS), a solid waste taking up a large amount of public resources, contains abundant phosphorous and urgently needs appropriate recovery, but incineration, the existing popular SS treatment method, fails to reuse phosphorous as a feasible product due to the poor phosphorous bioavailability of SS ash. Based on the mono-combustion of SS, magnesian minerals comprising of magnesium oxide were doped with SS to carry out the behavior of magnesium in phosphorous capture and its sensitivity to subsequent thermochemical modification. Five percent MgO improved phosphorous capture, and its effectiveness was disturbed by sulfur at 900 °C. The more H2O that was pumped into the atmosphere, the more phosphorous was captured by 5% MgO. The capacity of MgO in phosphorous capture was inferior to that of CaO. The utilization efficiency of MgO for phosphorous capture was inferior to that of CaO. A total of 7.2% MgO succeeded in recovering 97.46% phosphorous with 5% H2O at 900 °C. A total of 15.06% hydromagnesite merely promoted 1.85% and 5.13% of the phosphorous relative enrichment factor (RE) in SS ashes without or with 5% H2O, respectively, whereas it recovered 90.21% phosphorous with 10% H2O, supposing a potentiality in phosphorous capture for the direct combustion of wet SS. However, having been improved by magnesium, the bioavailability of phosphorous in SS ash remained extremely limited. Thus, thermal modification by K2CO3 was applied, where the limited bioavailability of phosphorous in the SS ashes was remarkably alleviated; although, SiO2 and sulfate were the main disturbers and led to the production of K2MgSiO4 and K2Mg2(SO4)3. The effective constituents were KMgPO4 and K3CaH(PO4)2 in the final mixed fertilizer. The obtained mixed fertilizer might be suitable for application on acidic soils.

“…Furthermore, the thermochemical calculations show that above 800 °C a Zn containing slag phase starts to form, while Zn mainly occurs in a molten slag phase at temperatures above 1000 °C. The presence of Zn bound in aluminate spinel, ferrite spinel and silicates in SSA was previously discussed in studies by Cai et al [45], Fraissler et al [60], Guo et al [46], Liu et al [75] and Nowak et al [42]. However, aluminate spinels, ferrite spinels and silicates generally show poor solubility, so the results of the thermochemical calculations do not sustain the Zn extraction trend observed for SSA samples obtained at 550 and 650 °C.…”

“…It contains high concentrations of organic dyes and inorganic salts, which puts a high threat to the aquatic environment. − With the improvement of China’s requirements for dye purity and high level of wastewater discharge standards, increasing attention has been generated to disposing of crude dye wastewater like separating the dyes and inorganic salt to recover the dyes. − Adsorption, coagulation, ozone oxidation, and electrolysis methods are the common methods used to treat the dyeing wastewater. However, the poor efficiency of dye desalination by the above methods did not satisfy recovering the precious resources, not to mention the high investment costs, large operating area, and poor treatment effect. − …”

In this work, the novel mixed-dimensional nanofiltration membranes [halloysite nanotubes (HNTs)/Kevlar aramid nanofiber (KANF)] with the ability to separate small-molecule dye/salt mixtures were prepared by comprising the rigid HNTs and the soft KANF. The considerable sieving in separating low-molecule dyes from dye/salt mixture solution was designed via the provision of additional channels for water molecules and salt ion transport via the special structure of the hollow structure of HNTs. The optimal 30% HNTs/KANF membrane displayed an eightfold water flux (39.2 L m–2 h–1) of the HNTs-free membrane, the low rejection of salts (21.7% for Na2SO4 and 7.7% for NaCl), and high rejection of various dyes (98.7% for Coomassie brilliant blue G-250, 95.3% for Congo red, 99.5% for Eriochrome black T, and 98.0% for Tropaeolin O). Besides, owing to the hydrophilicity of HNTs and the highly ordered and compact structure of KANF, the HNTs/KANF mixed-dimensional membrane showed excellent antipollution performance and long-term stability. This study provides some ideas for improving the permeability and selectivity of nanofiltration membranes by adding nanomaterials with special structures.
