微曝气生态浮床净化井研县茫溪河水质工程设计

Micro Aeration Ecological Floating Bed Purification Engineering Design for Mangxi River in Jingyan County

近年来茫溪河水质日益恶化,河水中氮、磷富营养化程度不断加剧,从而造成井研县内水资源紧缺,因此对于茫溪河水质净化迫在眉睫。通过资料查找,得到目前茫溪河水质类别为Ⅴ类甚至是劣Ⅴ类,属于氨氮营养型污染。针对上述问题,在传统生态浮床基础上设计了一套完整的微曝气生态浮床系统,以此来净化茫溪河水质,此系统主要由湿式有框浮床悬挂弹性立体填料+微曝气系统组成。

In recent years, the water quality is increasingly deteriorating in Mangxi River, the nitrogen and phosphorus in the eutrophication degree is gradually increasing, which results in the water resources shortage in Jingyan County, so the water purification of Mangxi River is imminent. Through the information search,repeatedly for river water quality categories is Ⅴ class or worse Ⅴ class, and the pollution of Mangxi River belongs to ammonia nitrogen nutrient pollution. Aimed at the problems above, based on the traditional ecological floating bed, a set of complete micro aeration system was designed. It consisted of wet box floating bed which hangs elastic three-dimensional packing and micro aeration system.
