Electric pulse treatment of organic waste before anaerobic fermentation

Abstract

One of the promising areas of processing organic waste from agriculture is through methane fermentation in biogas plants. They have important advantages over other methods of processing organic waste. Based on these problems, the article describes a method of processing organic waste under anaerobic conditions using electric pulse treatment of organic waste before loading into a biogas plant. The parameters of the production process of the bioenergy plant had the following values: humidity of organic waste 88-94%; the pressure of the gas phase in the bioreactor -2-3 kPa; the dose of daily updating of the mass volume in the bioreactor is 10% / day; the duration of one cycle of mixing 10 min; the frequency of daily mixing 17 days−1. Based on the equation, taking into account the listed optimal values of the factors, the biogas yield per 1 kg of OM was calculated and 0.146 m3 of BG/kg of OM was obtained. Laboratory and production results are given, as well as a comparison of the data obtained.

Efficiency of land preparation methods for planting

“…To provide high-quality sown areas, one must perform current or major leveling in a timely manner, using "stacking" and "planting" to maintain a fertile soil layer. There is a 4-5 center increase in cotton yields per hectare planted by the "plantation" method [20][21][22], and irrigated farming produced more than 90% of the yield because of sufficient water resources in agriculture, energy-saving technique of leveling agricultural lands using improved disc softener base levelers, allowing performing simultaneous softening and leveling operations saving up to 20% of irrigation water. In discsmoothing base levelers, the surface area of flattened fields is uniform without high-lows, where the water is evenly distributed and the crop area soil is evenly moistened [1][2][3], when the current and operational leveling of lands in irrigated areas is 25-30% of the total land area of farms before planting in autumn and spring with long base P-2,8A, P-4, PA-3, PPA-3,1.…”
