摘要

Piggery wastewater contains high concentrations of organic matter and ammonia nitrogen, and it is difficult to treat it and make the discharged wastewater to meet the standard. Since the treatment of piggery wastewater treated under anaerobic conditions by traditional aerobic methods requires large investment, high running expense and strict management, breeding enterprises could hardly accept the technique. According to the characteristics of piggery wastewater, Pennisetum sp. + Rumex acetosa Linn and Populus + Nerium oleander can be planted in constructed wetlands to treat piggery wastewater, which can improve the treatment effect of piggery wastewater by constructed wetlands, solve the difficulty of wastewater treatment in winter, and bring obvious economic benefit.
