چکیده

This study aims to design a smart closed reactor of vermicomposting convert sewage sludge and any organic waste high-quality vermicompost. In this design, all aspects growth reproduction Eisenia Fetida worms, such as aeration, temperature, light, moisture, were considered. We analyzed the physicochemical, bacterial, microstructural produced vermicompost rate worms in substrate 70% sludge, 20% cow manure, 10% sugarcane bagasse container reactor. The results show that took 50% less time 30% more worm produce same quality container. After reactor, parameters pH, fecal coliform, phosphorus, matter, C/N decreased whereas carbon, nitrogen, nitrate, ammonia EC increased, slightly. Although, amount production is than one, matter one. Based on odor absorption leachate elimination we recommend it be utilized for production, including out smelly wastes even public zone personal houses.

Vermicomposting of cow dung, kitchen waste and sewage sludge with bagasse using Eisenia fetida

The sugar cane industry produces significant amounts of cane trash and bagasse. Inappropriate disposal of agro-wastes can lead to environmental problems. Converting wastes such as cane trash and bagasse (Bg) to a fertilizer and conditioner is the aim of sustainable waste management in sugar cane industry. Cow dung (CD), kitchen waste (KW), and sewage sludge (SS) were mixed with bagasse as amend...

Stability and Kinetic Analysis during Vermicomposting of Sewage Sludge

The present study is aimed at alteration of sewage sludge into stable compost product using vermicomposting of sewage sludge mixed with cattle manure and saw dust in five different proportions based on C/N ratios (C/N 15 (R1), 20 (R2), 25 (R3) and 30 (R4); and control (R5)) by employing an epigeic earthworm Eisenia fetida. Higher reductions in C/N ratio, CO2 evolution and OUR were observed in R...

Production of Bio-oil by Oxidative Pyrolysis of Sewage Sludge in Rotating Fixed Bed Reactor

Pyrolysis is an attractive thermal conversion technology used to produce bio-oil and some chemicals. In this study, we investigated the pyrolysis of sewage sludge under N2 and CO2 atmosphere at various temperatures (350-750°C) in a rotating fixed bed reactor. For under N2 atmosphere, thermal gravimetric analysis (TGA) shows two major reaction peaks centered at 300 and 500°C. However, if CO2 was...
