摘要
杞麓湖流域终年进行蔬菜种植,有大量废菜叶产生。调查了杞麓湖流域废菜叶污染现状及其入湖比例,对废菜叶污染成分含量进行了测试,并估算了进入杞麓湖的废菜叶的污染负荷产生量,结果表明,杞麓湖流域每年约有38万t废菜叶产生,其入湖比例约为20%;入湖废菜叶产生的有机质、N、P分别为3 782.52、192.20、20.37 t/a。因此,利用微生物发酵技术将流域内废菜叶转化成生物发酵饲料是提高流域废菜叶资源化利用水平和改善杞麓湖水质的关键。
A lot of waste vegetable leaves are produced in Qilu Lake basin where vegetables are grown throughout the year. ＇lhe pollution situation of the waste vegetable leaves in Qilu Lake basin and the proportion of those waste vegetable leaves drained into Qilu Lake were investigated, the content of contaminants in the waste vegetable leaves was tested, and the generation of the pollution load from those waste vegetable leaves drained into Qilu Lake was also estimated. The results showed that about 380 000 tons of waste vegetable leaves were produced every year, of which about 20% were drained into Qilu Lake, and the amounts of organic matter, nitrogen and phosphorus drained into lake along with waste vegetable leaves were 3 782.52, 192.20 and 20.37 t/a respectively. Therefore, converting the waste vegetable leaves into biological zymolytic feed by microorganism fermentation technology was the key to promote the resourceful utilization of the waste vegetable leaves and improve the water quality of Oilu Lake.
