Method for quickly treating sewage

Abstract

The invention relates to the field of sewage treatment methods and particularly discloses a method for quickly treating sewage. The method adopts a sewage treatment device, and a filtering layer in the device can preliminarily filter out solid impurities in sewage; and in the filtering process, when the filtering layer reaches the filtering limit, a rotating mechanism in the device can drive the filtering layer to be moved to the position of a sewage bucket, and then, the filtering layer is washed to enable the solid impurities adhering to the surface of the filtering layer to be cleared, thereby greatly increasing the utilization ratio of the filtering layer.

Description

technical field [0001] The invention belongs to the field of sewage treatment methods, in particular to a method for quickly treating sewage. Background technique [0002] With the growth of the urban population in our country, the domestic water consumption in the city is also increasing. The urban domestic sewage is mainly composed of kitchen washing, toilet flushing, bathing, laundry water, etc. The sewage contains many solid substances, organic nitrogen and Ammonia nitrogen, a large amount of solid matter, organic nitrogen and ammonia nitrogen contained in sewage has become the main pollution source of urban water in my country. If it is discharged into rivers and lakes without purification, it will pollute natural water bodies and the surrounding environment; a large amount of sewage is directly discharged. Destroy the ecology, but also seriously endanger the production of industry and agriculture and human health and safety. [0003] When treating domestic sewage, the s...

Problems solved by technology

[0003] When treating domestic sewage, the solid impurities in the sewage are generally filtered and initially removed, and then the organic nitrogen and ammonia nitrogen in the sewage are decomposed and treated. The treated sewage can be discharged into nature. When filtering solid impurities in sewage, filter materials are often used to mechanically filter impurities in sewage. During the filtering process, the filter holes in the filter material will be quickly blocked, resulting in the need for high-frequency replacement of filter materials. During the replacement process, it is necessary to suspend the filtration of sewage, resulting in a decrease in the filtration speed of sewage. At the same time, it is necessary to consume a large amount of filter materials to filter the sewage, resulting in high filtration costs of sewage, which in turn leads to high filtration efficiency of sewage.
