Special Issue Information

Dear Colleagues,

Carbon neutrality has become one of the major challenges to the sustainable development of human society. The quantity of biomass waste has risen sharply, causing serious environmental pollution. In terms of wastewater treatment, the discharge of biomass waste accounts for a great quantity of the total, and the achievement of biomass waste untilization has practical significance in carbon neutrality. At present, a lot of research has been done on biomass waste recycling and utilization, mainly focusing on thermal conversion, along with anaerobic and aerobic technologies. These technologies can transform recyclable organic materials from biomass waste into various solid, liquid, and gaseous fuels, which are of great significance to alleviate energy shortages and environmental pollution. Therefore, sustainable wastewater treatment through the the utilization of biomass waste and the application of energy and bio-materials to improve utilization efficiency is a focus of contemporary research.  We propose a Special Issue of Water to accommodate recent research carried out in these fields.

This Special Issue is intended to present novel, high-quality, original research articles as well as review articles/short communications/letters focused on biomass waste utilization technologies in sustainable wastewater treatment.

  1. Thermal conversion technology/anaerobic technology/aerobic technology for biomass waste untilization and wastewater treatment.
  2. Resource recovery technologies for sustainable wastewater treatment .
  3. Application of bio-energy and bio-resources in biomass waste recovery for wastewater treatment.
  4. Energy and bio-materials generated by thermal conversion of biomass waste for wastewater treatment applications.

With the gradual advancement of urbanization, urban hardened roofs and pavements are increasing, and the rainwater cycle is being seriously damaged; sponge city construction has become an inevitable trend to address this problem. The analysis of the infiltration and storage performance of recycled brick aggregate, which is highly absorbent and can be used as a permeable paving material in sponge cities, is of great significance. The study firstly designed a simulated rainfall test device, then carried out tests in terms of aggregate gradation, aggregate type, and aggregate grade, and finally analyzed its effect on the void structure and infiltration and water storage performance of recycled brick mix aggregates. The outcomes demonstrate that the particle size of recycled brick concrete aggregate is positively related to the water storage capacity, and the volume water storage rate of recycled sand is close to 26%. The fitting result of 1 h water storage rate under different dosage is 0.984. After 1 h of rainfall, the water storage rate is 3 times that of natural aggregate, and the volume water absorption rate is 2.5 times that of natural aggregate. This indicates that recycled brick concrete aggregate has strong permeability and water storage properties and has great potential for application in sponge city construction, and the study provides a reference for the optimal design of subsequent cities.

Due to low efficiency and the material choice limitations of traditional evaporation systems to treat acid wastewater, humidification and dehumidification (HDH) as the core process was applied in the treatment and reduction of wastewater with organic acid pollutant concentrations. The forecasting of pH changes and COD reduction is important for the system’s design. Therefore, a study of the pollutant removal efficiency with different parameters, such as the reaction temperature, air quantity, and flow rate was conducted with ASPEN modeling. In this article, ASPEN modeling was used to simulate the water and acid material transformation in HDH system. The process was composed of blocks, such as RadFrac, heater and split. The analysis was taken with different air quantities, tower diameters, heat loads and flow rates. The analysis indicated that the pH of the maleic acid wastewater changed from 3.0 to 5.7. The relationship between inlet quantity, air quantity, inlet heat and the clean water yield was also shown in the modeling results. Based on these studies, we determined that the model can help engineers solve the key problems of HDH systems, such as heat balance calculation, equipment selection, and the prediction of incoming and outgoing evaporation materials.

Water environment safety is the focus of engineering measures to eliminate liquid digestate in farmland. It is of great significance to study the aging characteristics of soil absorbing and fate of liquid digestate ammonium nitrogen (NH4+-N) to realize safe and efficient disposal. In this paper, simulation experiments of digesting NH4+-N (with application of 0, 120, 180, and 300 kg/hm2) by static soil column are carried out to study disposal efficiency, migration and transformation characteristics, and fate proportion of NH4+-N in saturated water content soil. The result showed that after 3 days of application, the overlying water NH4+-N concentration decreased by 63.5–80.7%, and the reduction rate of total NH4+-N was 65.8–82.3%. After 4 days, the NH4+-N concentration of pore water in the 0–10 cm soil layer reached the peak value. After 7 days, the NH4+-N concentration adsorbed by the 0–10 cm soil layer reached the peak value. After 15 days, the overlying water NH4+-N concentration decreased by 97.0–98.7%, the reduction rate was 97.9–99.2%, and the proportion of NH4+-N absorbed in the 0–10 cm soil layer accounted for 63.5–76.3%. The disposal is mainly based on soil sorption and pore water migration. A duration of 0–3 days is the rapid disposal period, and 15 days is the completion period of safe digestion. Full article

The dramatic increase in the use of biomass waste has caused a serious environmental pollution phenomenon. Biowaste valorization to produce advanced material-hydrochar is regarded as a promising carbon neutrality technology for biomass waste recycling and utilization. Hydrochar obtained by hydrothermal carbonization has attracted much attention due to its regular morphology, good physical and chemical stability, and abundant oxygen-containing functional groups on the surface. This reviews the preparation of hydrochar and the basic methods of modified hydrochar and expounds on the related reaction mechanism of adsorption. The adsorption and recovery of heavy metals, Cr (VI) and Cd (II), in wastewater by hydrochar were focused on. The experimental conditions of hydrochar, such as synthesis temperature, synthesis time, modified condition, adsorption capacity, adsorption isotherm, and adsorption kinetics, were compared. The adsorption conditions of hydrochar for Cr (VI) and Cd (II) in wastewater, including the adsorption pH value, the adsorption time, the adsorption temperature, and so on, have been summarized. The review develops a better understanding of Cr (VI) and Cd (II) adsorption by hydrochar in wastewater, making an innovative perspective for the improvement and large-scale application of hydrochar as an advanced carbon material as well as biowaste utilization.
