Natural ventilated water plants, aggregate bed sewage treatment plant

摘要

This study is about the sewage treatment plant of aquatic plants and bone materials,The composition of the utility model is composed of reed strips (10) and water grass troughs (20) arranged at a lower position,The reed cage is paved with a shaft (17) on and around the floor, on which aggregate (11) such as crushed stone is loaded, and then reed (12) is planted,At the lower end of the aggregate, a plurality of air holes (15) and a drainage pipe (13) connected by a plurality of vertical and synchronous guide pipes (16) expose the end of the main drainage pipe (14) to the upper part of the water straw trough, discharge the sewage filtered from the reed trough to the trough, and supply oxygen to the aggregate and the reed at the same time then.In order to purify the sewage inducing membrane (22) and plant perennial water grass (23) on the upper part of the water trough, an axle is laid on the ground and around the water trough and sand like aggregate (21) is loaded on it,In addition, the utility model has the characteristics that the purified water is put in a discharge pipe (24) of a river (26).According to these components, the lower part of reed and aggregate of reed strip can be naturally ventilated to provide enough oxygen for microorganism and reed growth, so as to promote its propagation and activity, thus enhancing sludge decomposition capacity, improving sewage purification effect, and reed plays a heat preservation effect, Therefore, regardless of the season, it has good sewage treatment capacity.
