摘要
固定化多孔悬浮陶瓷载体的挂膜废水处理工艺吸收了传统活性污泥法、生物接触氧化法和生物流化床三种工艺优点,以预固定微生物的多孔悬浮陶瓷作为挂膜载体,用泡沫陶瓷板作曝气头进行底层曝气挂膜试验。模拟废水处理试验表明:COD降解率较空白载体的提高6.58%。
The wastewater treatment technique of membrane forming on suspended immobilized porous ceramic carrier has absorbed the merits of conventional sludge activation, bio-contact oxidation and bio-fluidized bed. The experiment of membrane forming using foamed ceramics board as aerator, and bottom aeration was carried out with biomembrane formed on suspended immobilized porous ceramic carrier. The simulated experiment of waste-water treatment indicated that the degradation rates of CODcr had risen 6.58% compared to that of the blank carrier.
