The discharge of textile wastewater (TWW) into the environment releases multiple toxic substances that pose a significant threat to aquatic life. Most studies evaluating treatment efficiency focus on removal parameters, such as chemical oxygen demand (COD), total organic carbon (TOC), dissolved (DOC), biochemical (BOD), and colour. One processes has presented high efficiencies in TWW is use biochar (BC) an adsorbing material. BC shown ability remove complex from water since it able decrease content COD, TOC, DOC. However, toxicity treated effluents not been widely studied. In this regard, essential only treatments removing matter but also their reduce WW toxicity. This research evaluates acute real with Pinus patula by using Daphnia pulex sentinel species. For purpose, D. individuals were exposed BC-treated for 48 h, mortality defined absence movement limbs antennas. It was found although P. 120 min eliminated 72.8% initial DOC under optimal conditions (pH 3 13.5 g/L dose), effluent remained toxic, inducing 85.7% 71.4% rates 100% (v/v) 50% dilutions. Despite increase survival rate due protective effect achieved constituents contained reconstituted samples, these findings emphasize necessity conducting before considering after having treated.

This study presents a novel approach that integrates hydrothermal carbonization (HTC) technology with circular economy principles to optimize the management of nitrogen and phosphorus in agricultural wastewater. Given increasing global resource scarcity continuous ecological degradation, valorization biomass wastewater has become critical pathway for promotion sustainable development. Biomass wastewater, which contains crop residues, forestry leftovers, food processing byproducts, long been regarded as useless waste. However, this abundant organic matter possesses significant renewable energy potential. The can significantly reduce environmental pollution. Through optimization HTC process parameters, we achieved an improvement quality yield carbonized products, facilitating efficient recycling utilization resources. research demonstrates transform into valuable biofertilizers, energy, feed, while simultaneously reducing reliance on fossil fuels, decreasing greenhouse gas emissions, mitigating impact activities. paper provides comprehensive exploration application ecosystems, highlighting its beneficial role management, efficiency, pollution reduction. findings suggest holds potential optimizing treatment, promoting recycling, advancing Furthermore, offers theoretical support practical guidance implementation is paramount importance fostering economic development achieving agriculture.
