摘要
通过在香河生态园建设水生蔬菜集成净化系统对农田退水进行净化效果监测,种植水芹、茭白、慈姑、西洋菜、蕹菜和莲藕,搭配水生态治理工艺,研究在实际使用情况下水生蔬菜集成净化系统的净化效果和经济收益。结果表明:水生蔬菜集成净化系统对总氮(TN)、总磷(TP)和高锰酸盐指数(COD_(Mn))的去除率均值分别为51.13%、68.09%和20.44%,TN去除率范围为19.23%~80.04%,TP去除率范围为29.41%~88.02%,COD_(Mn)去除率范围为7.69%~38.81%,共生产11996 kg蔬菜,总产值为73123元。水生蔬菜集成净化系统基本达到了预期净化目标,并可以产生经济收益,可以进一步地推广净化处理农田退水,为水生蔬菜净化生态环境提供数据和技术支持。
The integrated purification system of aquatic vegetables was constructed in Xianghe Ecological Park to monitor the purification effect of farmland backwater.Water cress,water cane,mushroom,watercress,spinach and lotus root were planted and the water ecological treatment technology was used to study the purification effect and economic benefit of the integrated purification system of aquatic vegetables in actual use.The results showed that the average removal rates of total nitrogen(TN),total phosphorus(TP)and permanganate index(COD_(Mn))were 51.13%,68.09%and 20.44%,respectively.The removal rates of TN ranged from 19.23%to 80.04%and the removal rates of TP ranged from 29.41%to 88.024%.The removal rate of COD_(Mn) ranged from 7.69%to 38.81%,and 11996 kg of vegetables were produced,with a total output value of 73,123 yuan.The integrated purification system of aquatic vegetables has basically reached the expected purification target,and can generate economic benefit.It can be further promoted to purify and treat farmland backwater,and provide data and technical support for the ecological environment of aquatic vegetables.
