Description
Technical Field
The invention relates to the field of urban sewage treatment, in particular to a filter-feeding type efficient urban sewage treatment device.
Background
Municipal sewage is domestic sewage, industrial wastewater and runoff sewage in the urban area. Generally, urban canals and canals collect and need to be discharged into a water body after being treated by urban sewage treatment plants, along with the gradual deepening of the environmental protection concept of people, the plants are required to be equipped with special sewage treatment devices in the construction process for treating sewage generated in the industrial production process of the plants, and therefore, the main object of urban sewage is domestic sewage.
Compared with industrial sewage, domestic sewage obviously has the characteristic of eutrophication, and the outbreak of algae in freshwater lakes caused by the random discharge of the domestic sewage every year is not critical, so that the treatment of the domestic sewage is extremely important.
Filter feeders are animals that ingest plankton in the water in a filtered manner, including both swimming feeders and sessile feeders, and filter feeders screen food from the nearby seawater environment. The feeding mode is very efficient and is adopted by animals living in fresh water and oceans, the filter feeders take gills and/or teeth in mouths as filter screens, small plankton is filtered by sucking and spitting water, most of the filter feeders moving in the filter feeders are high-grade cervical vertebra organisms such as blue whales and the like, most of the filter feeders moving in the filter feeders are large organisms, most of the filter feeders fixing in the filter feeders are invertebrates such as tongue-shaped shells and the like, and most of the filter feeders fixing in the filter feeders are small organisms, so that compared with the filter feeders fixing in the filter feeders, the swimming filter feeders are an efficient feeding mode.
Traditional domestic sewage treatment plant is similar to the setting in the use and strains food, relies on rivers self to flow to realize that the impurity filters, and filtration efficiency is lower, is difficult to satisfy growing domestic sewage treatment capacity.
