Problems solved by technology

However, because the reoxygenation effect of the falling dam on the water body is instantaneous, the reoxygenation capacity is limited and the action time is short, so the removal effect of pollutants is also limited

Abstract

The invention provides a drop-aeration water treatment system which comprises a microorganism filter pool and a drop dam. The microorganism filter pool comprises multiple stages of microorganism filter beds which are connected in series and provided with water inlet pipes at water inlets. The microorganism filter bed at the head end is connected with a water inlet pump. The microorganism filter bed at the tail end is connected with the drop dam. Each microorganism filter bed comprises carrier filler, an upper tempered glass grating plate covering the carrier filler, a floating bed arranged on a water body above the upper tempered glass grating plate, aeration nozzles laid blow the carrier filler, and a lower tempered glass grating plate arranged below the aeration nozzles. The system integrates biological and ecological processing, reoxygenation and the landscape effect, and is good in treatment effect and suitable for river channel water bodies.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water treatment system utilizing falling water aeration. Background technique [0002] There are many rivers in urban and rural areas, but at the same time of rapid economic development, a large amount of agricultural non-point source pollution, domestic sewage and industrial wastewater are discharged into the river, which has a serious impact on the water body of the river. Due to the long-term reception of sewage in polluted rivers, the water quality deteriorates and even black and smelly, and the ecological environment of the water body is seriously degraded or even destroyed. [0003] In the prior art, the treatment of polluted rivers and the application of drop dams are mainly for water reoxygenation and landscape effect, but the real sewage treatment effect is not ideal. For example, the falling water aeration of the falling dam can increase the dissolved oxygen...
