Abstract

Bioenergy is the most outstanding renewable source among other fuels that are non-renewable and running out. Globally, the main cause of the energy crisis is a scarcity of natural resources. In this respect, harnessing the abundant renewable sources for energy production can help to alleviate the crisis of energy. Developing countries needs an incessant supply of cheap and clean energy sources. Bioenergy production from biomass such as manure, agricultural residue, and municipal solid waste. it is economically feasible because organic substrates have high nutritive values for micro-organism (especially kitchen waste), high biodegradability rate, and high calorific values. This study has investigated the anaerobic co-digestion of wastewater sludge, Manure and kitchen waste for bio-energy production and analyzed the parameters which have significant effect on digestion process. This process has also decreased the excess of BOD, COD, N and P about 64.07%, 60.16%, 56.06% and 71.02% respectively which indicated the organic fraction utilized by microbes. Anaerobic co-digestion enhances biogas production when treating such wastes wastewater sludge, Manure and kitchen waste combined.

提高污水污泥、厨余和粪便厌氧共消化的沼气产量

生物能源是其他不可再生和即将耗尽的燃料中最突出的可再生能源。在全球范围内，能源危机的主要原因是自然资源的匮乏。在这方面，利用丰富的可再生能源生产能源有助于缓解能源危机。发展中国家需要源源不断的廉价清洁能源供应。从诸如粪便、农业残渣和城市固体废物等生物质中生产生物能源。这在经济上是可行的，因为有机基质对微生物具有高营养价值(特别是厨余垃圾)，高生物降解率和高热值。研究了污水污泥、粪便和厨余垃圾厌氧共消化的生物能源生产工艺，分析了影响消化过程的主要参数。该工艺还使水体中BOD、COD、N和P的过剩量分别降低了64.07%、60.16%、56.06%和71.02%，表明微生物利用了有机馏分。厌氧共消化提高沼气产量时，处理这类废物废水污泥，粪便和厨余废物相结合。
