Developing algae cultivation for food, chemicals, and bio-energy generates a significant amount of algal waste/residue after utilization. Meanwhile, harmful blooms caused by abnormal proliferation various produce large biomass, posing serious harm to human health, the environment economy. Converting body biochar is crucial method with which take advantage this resource. Biochar usually has specific surface area, developed pore structure, high cation exchange capacity rich functional groups. With stable physical/chemical properties easy modification techniques, posited as an ideal adsorption material. From perspective biomass utilization, paper reviews preparation methods, structural characteristics, physicochemical environmental implications biochar. The effect mechanisms on nutrients, heavy metals, organic matter in water are introduced. In light current research status, challenges faced practical application algae-derived materials pointed out, direction also developed, view providing reference further utilization

The massive loss of nitrogen (N) and phosphorus (P) from farmland ditches contributes to non-point source pollution, posing a significant global environmental challenge. Effectively removing these nutrients remains difficult in intensive agricultural systems. To address this, novel composite ecological ditch system (CEDS) was developed by modifying traditional drainage integrate grit chamber, zeolite, floating beds. Dynamic monitoring N P levels water, plants, zeolite conducted evaluate the system’s nutrient interception performance mechanisms. results showed following: (1) Water quality improved markedly after passing through CEDS, with concentrations decreasing progressively along flow path. intercepted 41.0% 31.9% P, inorganic particulate as primary forms loss. (2) Zeolite removes primarily ion exchange, likely chemical reactions, maximum capacities 3.47 g/kg for 1.83 P. (3) Ecological beds hydroponic cultivation enhanced uptake roots Canna indica Iris pseudacorus, surpassing (4) Nutrient efficiency positively correlated temperature, inlet concentrations, rice runoff but negatively precipitation. This study demonstrates CEDS’s potential improving water suggests further enhancements design management increase its economic aesthetic value.

Unlike residential settlements, Chinese traditional defensive settlements (CTDS) are fortress-shaped built by forefathers to resist invasion and defend their homeland. What remains of these today not only unique entities but also spatial layouts architectural techniques that reflect military defense strategies patterns ancient society, resulting in a distinct cultural heritage. Using CiteSpace as research tool CNKI core database, this paper conducts visual analysis review the related CTDS, aiming accurately intuitively elaborate on literature distribution characteristics, collaborative key issues, trends, hotspots. We found CTDS focuses three issues: composition system mode northern style characteristics southern dwellings, settlements’ heritage conservation development planning; trends can be divided into phases. propose five future recommendations. This study helps fill gap bibliometric serves reference for priority directions, provides manual sustainable special type settlement.

Water scarcity is a critical issue worldwide. This study explores novel method for addressing this by using ductile cast iron (DCI) solid waste as an adsorbent phosphate ions, supporting the circular economy in water remediation. The was characterized XRD, XRF, FTIR, and particle size distribution. Wastewater samples of different ion concentrations are prepared, used to adsorb ions doses process time. removal percentage attained through spectrophotometer analysis experimental results optimized get optimum conditions Design Expert V13. pseudo-second order (PSO) kinetics model Langmuir isotherm were fitted with maximum adsorption capacity (q max = 0.28 mg/g). thermodynamic indicated that spontaneous based on negative value Gibbs free energy (∆G). Additionally, positive values enthalpy (∆H) endothermic nature system.
