Abstract

Artificially strengthened filter bed is an innovative wastewater treatment technology based on the coupling of eco-contact oxidation filters and artificial wetlands purification mechanism. By small scale laboratory equipment, the effects of cascade aeration, filter type, filter clogging and other ecological factors on the operation effect of artificial filter bed were studied. As indicated by the results, the pretreatment of cascade aeration had obvious effect and could satisfy the oxygen requirements of artificially strengthened ecological filter bed. Through the analysis on the purification results of volcanic and gravel filter, the effluent quality of volcanic filter was better than that of gravel filter. With the advantages of low operations costs and good effluent quality, the artificially strengthened ecological filter bed has great value to be popularized in North China.
