摘要
随着畜牧业的快速发展,畜牧业的污染已成为农村面源污染的主要来源。针对目前养殖场所采用的厌氧处理工艺对NH3-N去除率较低的特点,实验提出在生物氧化塘中种植水生植物可提高生物氧化塘去除氮、磷的能力;指出采取妥善的措施,加强水葫芦的后期管理,利用水葫芦进一步净化畜禽污水将达到净化水质的效果。
Along with the fast development of the animal husbandry, the animal husbandry pollution has become the main pollution source in rural area. At present, the NH3-N removing rate is lower for the anaerobic treatment technology in farm stock, in the experiment, aquatic plant is used in the biological oxidation pond in order to improve its capability of removing the NH3-N and the phosphorus matters, suitable measures have been proposed for the administration of the aquatic plant-water hyacinth in order to achieve the objective of purify the farm stock sewage water.
