【摘要】：设计了具有气液固三相收集功能的强制通风自动搅拌好氧堆肥反应器,并对其进行了好氧堆肥性能试验,通过监测温度、p H、含水率、COD、BOD_5、重金属(Cu)、种子发芽率、热值等指标来判定堆肥效果。实验结果表明,反应器使堆肥周期大大缩短,COD、BOD_5及生物毒性降低明显,45 d后堆体基本腐熟且稳定,堆体减量30%,堆肥效果良好。独有的"耙形"搅拌有利于减少物料温度、湿度和氧气浓度的差异,加快了反应进程。底部二级过滤系统有利于改善渗滤液质量,方便渗滤液的收集及回灌。该反应器可为小型禽畜粪便堆肥反应器的研发和推广提供参考。
[Abstract]:The design of automatic mixing aerobic composting reactor with forced ventilation of gas liquid solid three-phase collecting function, and the performance of aerobic composting experiment is conducted, by monitoring the temperature, P, H, COD, BOD_5, water content, heavy metals (Cu), the seed germination rate, and other indicators to determine the calorific value. The experimental results show that the effect of compost so, the reactor composting period is greatly shortened, COD, BOD_5 and biological toxicity reduced significantly after 45 D pile basic maturity and stability, pile reduction 30%, composting effect is good. The unique "rake" stirring helps to reduce the material temperature, humidity and oxygen concentration difference, accelerate the reaction process at the bottom of the two. Filter system is conducive to improving the quality of leachate, leachate collection and convenient recharge. The reactor can provide a reference for the development and promotion of small livestock manure composting reactor.
