Phosphorus Removal from Dirty Farmyard Water by Activated Anaerobic-Digestion-Derived Biochar
نویسندگان
چکیده
The management of anaerobic digestate is important to realize the value waste and enhance whole system sustainability digestion. In this study, phosphorus treatment dirty irrigation water by biochar samples derived from digestion were investigated. biochars further activated steam activation with different duration time KOH introducing ratios; textural properties optimized after aspect characterization. Notably, AD-N2 demonstrates a remarkable adsorption effect phosphorus, an efficiency 8.99 mg g–1. Besides dosage on removal, kinetics thermodynamic isotherms are studied. According kinetics, fits Elovich equation (R2 = 0.95). Furthermore, isotherm results illustrate process removal endothermic (ΔH0 17.93 kJ mol–1) spontaneous (ΔS 96.24 J mol–1 K–1). Therefore, work suggests promising solution phosphorus-related environmental challenges in industry agriculture.

Biochar affected by composting with farmyard manure.
Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...
متن کاملModeling and Removal of Hydrogen Sulfide from Biogas Produced by Anaerobic Digestion
Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...

متن کاملBiological Phosphorus Removal During High-Rate, Low-Temperature, Anaerobic Digestion of Wastewater
We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for low-temperature (12°C) anaerobic treatment of synthetic sewage wastewater. Successful phosphate removal from the wastewater (up to 78% of influent phosphate) was observed, mediate...
