摘      要：This study is a continuation of our research work on the energy recovery of OM(Organic Matter)and the protection of the *** took place from October 1 to November 25,2021 in the poultry farm of *** Daye KABA in the Senkefra district,urban commune of *** this work,we designed,built and tested a 6 m^(3)*** dung(2,500 kg)with 2,300 L of water served as a substrate for the production of biogas during 30 days of *** following physico-chemical parameters:Temperature(T°C),Humidity(H%),Hydrogen potential(pH),Dry Matter(DM),Organic Matter(OM)and the ratio between Carbon(C)and Nitrogen(N)(C/N)of cow dung were determined,namely:T(28°);H(75%);pH(6.5);MS(15%);MO(55%)and C/N(25%).During the 30 days of digestion,the temperature varied from 27 to 35°C with an average of 30.57°C(mesophilic digestion);the pH varied from 6 to 9,with an average of 7.58;the daily production kinetics represented the four stages of digestion(hydrolysis,acidogenesis,acetogenesis and methanogenesis).The cumulative production of biogas is 198 m^(3).The composition of the biogas produced is 60%CH_(4),36%CO_(2),2%N_(2),2%H_(2)S and 1.5%*** biogas produced was used for lighting,water heating and *** results show that the biogas produced is of good quality and remains consistent with the literature.
