本文以牛粪、鸡粪、猪粪为对象,采用开放式堆肥方式,通过API5000三重四极杆质谱仪(最低检出限为0.5~1.0μg/L),考察了初始含水率及堆肥翻堆频率对好氧堆肥过程中抗生素消减的影响.结果表明,3种粪便中均存在磺胺类、氟喹诺酮类和四环素类抗生素残留.其中,这3类抗生素残留含量分别为1.37~72.43,26.26~37.1和24.48~34.81μg/kg.随着堆肥时间延长,粪便中抗生素残留量均呈下降趋势.经过32d堆肥处理,在一定初始含水率(55.87%~68.11%)和翻堆频率(不翻堆和2次/d)下,鸡粪、猪粪、牛粪的总抗生素去除率为78.09%~92.01%.改变堆肥初始含水率和翻堆频率可显著影响畜禽粪便中抗生素的消减速率.当堆肥初始含水率为68.11%,采用1次/2d的翻堆频率时,畜禽粪便中抗生素去除率高达100%.因此,可通过合理设计堆肥处理条件提高粪便中抗生素的去除效率,实现畜禽粪便资源化与无害化利用.

释放储能装置的频率支撑潜力,将是提升风、光高占比系统并网稳定性的关键。该文首先对比分析常规发电机组的固有惯量、风电机组的虚拟惯量及储能的惯性支撑特性。其次,根据系统中的储能容量配置,约束量化储能的虚拟惯量,为系统惯量需求提供评估依据,以保障频率安全。在此基础上,利用储能独特的功率支撑特性,提出恒频控制与调频状态转移控制结合的储能并网频率主动支撑控制策略,突破虚拟惯量及一次调频的传统控制模式。最后,搭建风电高渗透电网仿真系统,验证储能装置在所提控制策略下能够显著提升系统的频率稳定性,改善其对电网的主动支撑性能。
