堆肥是植物修复植物的后处理方法之一。由于水葫芦具有较强的污染物蓄积能力，本文研究了集约化畜禽废水中不同改性水葫芦生物量，包括未改性水葫芦(W)、泥炭改性水葫芦（WP）和猪粪改性水葫芦（WPM）在堆肥过程中的理化参数、微生物活性以及铜（Cu）和四环素（TCs）的命运。与W和WP处理相比，猪粪处理加速了堆肥过程，其温度、电导率（EC）、NH4-N和微生物群落功能多样性均有所提高。高Cu对堆肥过程有减缓作用，而tc对堆肥过程无减缓作用。泥炭的添加显著提高了最终堆肥中Cu的残留量，猪粪的添加显著提高了最终堆肥中有效Cu的浓度。铜在发酵后可有效转化为低有效（可氧化）和残余馏分。相比之下，在60天的堆肥结束时，所有处理的最终堆肥中测定的tc初始浓度不到0.5%。在堆肥过程中，高Cu浓度加速了TCs的消散。因此，堆肥是对含Cu和/或TCs的植物修复植物进行后处理和资源化利用的有效方法。
Composting is one of the post-treatment methods for phytoremediation plants. Due to a high potential of water hyacinth to accumulate pollutants, the physicochemical parameters, microbial activity as well as fates of copper (Cu) and tetracyclines (TCs) were investigated for the different amended water hyacinth biomass harvested from intensive livestock and poultry wastewater, including unamended water hyacinth (W), water hyacinth amended with peat (WP), and water hyacinth amended with pig manure (WPM) during the composting process. Pig manure application accelerated the composting process as evidenced by an increase of temperature, electrical conductivity (EC), NH4-N, as well as functional diversity of microbial communities compared to W and WP treatments. Composting process was slowed down by high Cu, but not by TCs. The addition of peat significantly increased the residual fraction of Cu, while pig manure addition increased available Cu concentration in the final compost. Cu could be effectively transformed into low available (oxidizable) and residual fractions after fermentation. In contrast, less than 0.5% of initial concentrations of TCs were determined at the end of 60-day composting for all treatments in the final composts. The dissipation of TCs was accelerated by the high Cu concentration during composting. Therefore, composting is an effective method for the post-treatment and resource utilization of phytoremediation plants containing Cu and/or TCs.
