【摘要】：堆肥過程中物料存在混合不均、曝氣不充分及發(fā)酵不徹底等問題,制約了有機(jī)物料有效生物轉(zhuǎn)化。為此,研制了一種新型槳式曝氣攪拌堆肥反應(yīng)器。裝置內(nèi)的上、中、下層內(nèi)設(shè)6個(gè)附有槳葉的攪拌槳,每個(gè)槳葉表面安置徑向撥片,可有效增加堆肥物料的徑向流動,從而使物料與空氣充分接觸。以牛糞、秸稈、麥麩與沼液為原料進(jìn)行批式好氧堆肥試驗(yàn),結(jié)果表明:該堆肥反應(yīng)器可有效實(shí)現(xiàn)攪拌、曝氣通風(fēng)同步進(jìn)行功能;罐體內(nèi)堆料各層維持50℃以上天數(shù)分別達(dá)到6.8、5.6、3.9天;各層物料種子發(fā)芽指數(shù)(GI)均值達(dá)到91.03%,可有效地實(shí)現(xiàn)混合物料堆肥無害化目標(biāo)。
[Abstract]:In the process of composting, there are some problems such as uneven mixing of materials, inadequate aeration and incomplete fermentation, which restrict the effective bioconversion of organic materials. Therefore, a new type of paddle aerated stirred composting reactor is developed. Six impellers with blades are arranged in the lower layer, each blade surface is placed with radial pluck, which can effectively increase the radial flow of compost material, thus making the material in full contact with air. The batch aerobic composting test was carried out with wheat bran and biogas liquid as raw materials. The results showed that the composting reactor could effectively realize stirring and aeration ventilation synchronously, and the days of maintaining each layer of material in the tank over 50 鈩，
