Reinforced vertical flow filter bed

Abstract

The invention relates to a reinforced vertical flow filter bed which is in a round structure comprising two semicircles, an anti-seepage membrane is laid at the bottom of the filter bed, a water collecting pipe is laid on the anti-seepage membrane, and both ends of the water collecting pipe are respectively connected with a ventilation pipe; a ground substance is filled inside the filter bed, and plants are planted on the surface of the filter bed; and a main water distributing pipe is respectively distributed on the two semicircles of the filter bed along the diameter direction of the filter bed, and branch water distributing pipes communicated with the main water distributing pipes are semicircularly and outwards radially arranged from the center of the filter bed. By adopting the round vertical flow filter bed structure, not only the module production of facilities can be realized, but also the water distribution on the surface of the filter bed is more uniform and comprehensive, the filter bed structure is more stable and attractive, more building areas and materials are saved, and the reinforced vertical flow filter bed is a higher-efficiency manual filter bed sewage treatment system, thereby solving the problems of imperfect treatment and the like caused by dead angles in a square filter bed. The facility is suitable for the treatment of rural domestic sewage, urban landscape water, lake sewage and the like, and has the characteristics of high treatment efficiency, good landscape effect, resource saving, flexible operation, wide application range and the like.

Description

technical field [0001] The invention relates to an enhanced vertical flow filter bed for treating sewage, which belongs to the technical field of environmental protection engineering and water treatment. Background technique [0002] At present, pollution source control and ecological restoration methods are mainly used to treat sewage, and artificial filter beds are one of the important scientific methods. The artificial filter bed is a constantly evolving sewage treatment technology. The basic principle is: plant specific plants on a certain filler. When the sewage flows through the artificial filter bed, it is filtered through sand and soil, and passes through one of the matrix filler sand layers. A variety of microbial activities in aerobic and anaerobic reaction micro-units and plant rhizosphere, biochemical degradation and precipitation, reduce the concentration of pollutants, purify the water quality, and discharge up to the standard. The treatment process includes b...
