چکیده
Anaerobic digestion and agricultural use of sewage sludge are effective methods to treat dispose sludge, respectively. Then, the anaerobic digested is applied in land improvement soil properties can be expected. In this study, with purpose evaluating potential co-digestion for use, plot experiments two vegetable species (radish Chinese cabbage) three application dosages were carried out a short term six months. Focus was on physical properties, nutrient change plant growth responses during whole process. Results showed that had little effect including bulk density, porosity, capillary porosity non-capillary porosity. However, after maximum increase content organic matter, total nitrogen, hydrolysable phosphorus available reached 51%, 125%, 212%, 15% 87%, respectively, which supplied nutrients quickly continuously. The promoted radish cabbage, observed through leaf, root biomass plants height. Consequently, has good prospect improving productivity as fertilizer.

Anaerobic co-digestion of coffee waste and sewage sludge.
The feasibility of the anaerobic co-digestion of coffee solid waste and sewage sludge was assessed. Five different solid wastes with different chemical properties were studied in mesophilic batch assays, providing basic data on the methane production, reduction of total and volatile solids and hydrolysis rate constant. Most of the wastes had a methane yield of 0.24-0.28 m3 CH4(STP)/kg VS(initia...
متن کاملAnaerobic co-digestion of municipal wastewater sludge and restaurant grease
Co-digestion has drawn much attention because of its potential to increase biogas production among other benefits. Restaurant grease has high energy content and methane production potential and so is a promising substrate for co-digestion with municipal wastewater sludge. Anaerobic co-digestion of municipal wastewater sludge and restaurant grease was investigated at laboratory-scale under mesop...
متن کاملAnaerobic co-digestion of municipal sludge with FOG enhances the destruction of sludge solids
The objective of this study was to investigate the benefits of co-digestion of a sludge-mix of primary sludge (PS)/thickened waste activated sludge (TWAS) with concentrated fat-oil-grease (FOG) over a wide range of FOG/sludge-mix volumetric feed ratios. The biodegradability (i.e., COD to methane conversion) of PS, TWAS, sludge-mix, and FOG was 43.0, 38.6, 41.8, and 97.7%, respectively, with a p...
