Background
With the rapid development of modern industry and urban construction, the environment on which human beings live is increasingly polluted. Untreated sewage and sewage which cannot reach the standard after treatment are directly discharged into rivers, lakes and seas, so that the pollution of a water body is aggravated. Serious water pollution and water resource shortage seriously restrict the development of socioeconomic development. Prevention and treatment of environmental pollution and ecological destruction are long-term strategic tasks, particularly the problem of water environment pollution. In order to change the current situation of water pollution, a new sewage treatment technology and new equipment are needed to be operated. The integrated sewage treatment process with high efficiency, low investment and low operation cost is the key and the first choice for future development.

Therefore, in order to improve the sewage treatment efficiency and the effect thereof, a quicksand filter is developed in the industry. The flowing sand filter greatly improves the sewage treatment efficiency. Although the treatment efficiency is improved, the sufficient contact time of the sewage and the flocculating agent is still insufficient, the flocculation effect is still low, and the difficulty in cleaning and treating the filter material is high. To this current situation, the utility model discloses to congeal, filter, deposit and make up an organic whole, set up through the subregion, make sewage and flocculating agent's contact time abundant, simultaneously with the help of adopting umbrella-type water-locator and supporting nozzle, show to have improved sewage and flocculating agent contact and mass transfer effect, flocculation effectual, efficient. Compare traditional quicksand filter, the utility model discloses have obvious innovation in the aspect of structures such as subregion setting, umbrella-type water-locator, cross water-locator, sewage treatment is effectual, with low costs.
