摘要
以陕西省咸阳市白良村的涝池水为例,通过测定其污染物的浓度和种类,制定有效的农村涝池水处理工艺流程。研究发现,以水生植物苦草-美人蕉-芦苇组合的人工湿地系统对COD、NH_(4)^(+)-N、TN和TP的去除效果最优,去除率分别为79.57%、92.12%、80.89%和85.23%。而白良村的涝池水生态处理系统设计为混凝沉淀-活性炭吸附-人工湿地系统,运行40 d后,系统对污染物COD、NH_(4)^(+)-N、TN和TP的去除率分别可达93.87%、95.46%、89.98%和87.36%,去除效果明显,最终以达到防洪排涝、人文景观、生态湿地、蓄水灌溉的目的,促使农村涝池海绵化。
Taking the water storage ponds of Bailiang village,Xianyang city,Shaanxi province as an example,the effective wastewater treatment of water storage ponds was developed by measuring the concentration and types of pollutants.It was found that,the removal rates of COD,NH_(4)^(+)-N,TN and TP were 79.57%,92.12%,80.89%and 85.23%,respectively,which was the constructed wetlands was combinate by aquatic plants bitter grass-canna-reed combination.And the water storage ponds wastewater treatment system was designed as the combination of coagulation precipitationactivated carbon adsorption-constructed wetland in Bailiang Village.After operation for 40 days,the removal rates of COD,NH_(4)^(+)-N,TN and TP was93.87%,95.46%,89.98%and 87.36%,respectively.In the end,flood prevention and drainage,cultural landscape,ecological wetland,water storage and irrigation will be achieved,so as to promote the sponging of rural waterlogging pools.
