Description

A kind of urban sewage separation and filtering device

Technical field

The invention belongs to the technical field of sewage treatment, and specifically relates to an urban sewage separation and filtering device.

Background technique

With the growth of my country's urban population, the expansion of residential areas and the further concentration of the population, domestic water consumption has also increased, resulting in an increasing amount of sewage discharged from the city. Urban domestic sewage is mainly produced by kitchen washing, toilet flushing, bathing, etc. , laundry water, etc. The organic nitrogen and ammonia nitrogen contained in sewage mainly come from waste products of protein metabolism in human food, such as feces. At present, urban domestic sewage has become the main pollution source of urban water in my country, and the existing sewage treatment Facilities are unable to withstand the increasing amount of sewage treatment, resulting in a large amount of domestic sewage being discharged into rivers and lakes without purification, polluting natural water bodies and the surrounding environment. Direct discharge of large amounts of sewage not only damages the ecology, but also seriously harms industrial and agricultural production. and human health and safety. Therefore, urban domestic sewage treatment is the top priority in current and future urban water environment protection work.

The sewage treatment process mainly uses chemical methods to separate the various components in the sewage, so that the final treated sewage meets the discharge standards. At the same time, the separated components are processed again to create economic benefits. Before chemical treatment, a separation and filtration device is required to filter out water-insoluble impurities in the sewage to achieve solid-liquid separation and avoid stains clogging the sewage treatment equipment.
