This book was released on 2000 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE PROTOXYDE D'AZOTE (N 2O) CONTRIBUE A L'EFFET DE SERRE ET A LA DEGRADATION DE L'OZONE STRATOSPHERIQUE ; L'OXYDE NITRIQUE (NO) EST IMPLIQUE DANS LA PRODUCTION D'OZONE TROPOSPHERIQUE ET LES DEPOTS ACIDES. LES SOLS, ET PLUS PARTICULIEREMENT LES SOLS CULTIVES, SONT UNE SOURCE IMPORTANTE DE CES EMISSIONS. LA PRODUCTION DE N 2O RESULTE ESSENTIELLEMENT DE DEUX PROCESSUS MICROBIENS : LA DENITRIFICATION QUI EST CONSIDEREE COMME LA PRINCIPALE SOURCE DE N 2O DANS LES SOLS ET LA NITRIFICATION DONT L'IMPLICATION DANS LES EMISSIONS DE N 2O N'EST PAS ENCORE REELLEMENT QUANTIFIEE. CONCERNANT LES EMISSIONS DE NO PAR LES SOLS, TRES PEU DE DONNEES QUANTITATIVES ET QUALITATIVES SONT DISPONIBLES ACTUELLEMENT. AU COURS DE CE TRAVAIL, NOUS AVONS MIS EN EVIDENCE QUE LES EMISSIONS DE N 2O ET DE NO PEUVENT SE PRODUIRE A PARTIR D'UN RENDOSOL, D'UN CALCISOL, D'UN NEOLUVISOL ET DE DEUX LUVISOLS FORTEMENT ENRICHIS EN AMMONIUM ET PLACES EN CONDITIONS D'AEROBIOSE. L'UTILISATION DE LA TECHNIQUE D'INHIBITION SELECTIVE PAR L'ACETYLENE, QUI A ETE PREALABLEMENT CALIBREE, A PERMIS DE MONTRER QUE, DANS CES CONDITIONS EXPERIMENTALES, LA NITRIFICATION EST LE SEUL PROCESSUS IMPLIQUE DANS LA PRODUCTION DE NO ET LE PRINCIPAL MECANISME DANS LA PRODUCTION DE N 2O. UNE DENITRIFICATION AEROBIE QUI PRODUIT N 2O A ETE OBSERVEE SUR UN DES LUVISOLS. LA PART D'AZOTE NITRIFIE EMIS SOUS FORME N 2O ET NO A ETE RESPECTIVEMENT ESTIMEE ENTRE 0.03 ET 1% ET ENTRE 0 ET 2.5% EN FONCTION DU SOL ETUDIE ET DE SON ETAT HYDRIQUE.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
