摘要

棉花栽培作为一项投资少、回报快的活动,对农村家庭生产者来说是一种可能。与此同时,我们强调这样一个事实,即利用液体鹌鹑养殖废物,旨在通过厌氧消化产生能量,这可能意味着从受限动物生产系统中获得沼气的一种可行且有前途的技术。对能源日益增长的需求表明,新能源得到了更好的利用,而在厌氧消化系统中使用生物质可能是它们增长的一个巨大机会,在厌氧消化系统中,有机基质被降解并转化为能源和生物肥料。所采用的方法是甲烷的生化势,通过体积为250 mL的台式生物反应器,在中温条件下。以鹌鹑蛋养殖场粪池废弃物为接种物。组成处理的基质是来自水深处理系统的鹌鹑养殖废液,沉积时间分别为15、30和45天。结果表明,最佳单消化方式为接种量+基质沉积30d,保水时间45 d,累积沼气产量最高(0.00078476 Nm3), CH4产量最高(0.000575 Nm3),沼气潜力最高(0.0043 Nm3 (kg底物)-1)。以鹌鹑养殖废液产生的沼气为燃料,通过电机发电机转化为电能,可获得104.64千瓦时(45天)-1的值。

Biogas production and electricity generation from a quail manure wastewater treatment system per water depth
Coturniculture, as an activity which demands low investment and quick return, is shown to be a possibility for the rural family producer. Concomitant to this, we highlight the fact that the use of liquid quail farming waste, aimed at generating energy by anaerobic digestion, can mean a viable and promising technology for obtaining biogas from confined animal production systems. The growing demand for energy establishes that new energy sources are better used, and a great opportunity for their growth may be the use of biomass in anaerobic digestion systems, in which the organic substrate is degraded and transformed into energy and biofertilizer. The method applied was Biochemical Potential of Methane, through benchtop bioreactors with a volume of 250 mL, and in mesophilic conditions. Waste was used as inoculum from the manure tank of the quail egg production farm. Thesubstrates used to compose the treatments were liquid quail farming waste from the water depth treatment system, with 15, 30 and 45 days of deposition. In the results obtained, it was verified that the best mono digestion used was inoculum+substrate of 30days of deposition, with water retention time of 45 days, showing a higher production accumulated in biogas (0.00078476 Nm3) and CH4 (0.000575 Nm3) as well as the highest biogas potential of 0.0043 Nm3 (kg substrate)-1. When converted into electrical energy, by means of a motor generator, using as fuel the biogas produced by the liquid quail farming waste, the value of 104.64 kwh (45 days)-1 was obtained.
