Abstract

The invention discloses a circulating filtration system for sewage treatment. The circulating filtration system comprises a shell, a rotary drum rotatably arranged on the shell around its own axis, aplurality of filter screen plates circumferentially arranged at intervals on the outer circle of the rotary drum, and a cleaning device for cleaning the filter screen plates, wherein the axis of the rotary drum is horizontally arranged and the filter screen plates are arranged in the radial direction of the rotary drum; water to be treated flows from top to bottom and passes through the filter screen plate rotated to the left side of the rotary drum to realize filtration; and filtered impurities are attached to the filter screen plates and rotated to the right side of the rotary drum to be cleaned by the cleaning device arranged on the right side, and a drainage channel for collecting and discharging clear water and an impurity discharging channel for collecting and discharging cleaned impurities are arranged below the rotary drum from left to right. The circulating filtration system can improve the sewage pretreatment efficiency, has a simple structure, a high automation degree, and alow equipment cost and is beneficial to popularization.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a circulating filter system for sewage treatment. Background technique [0002] Due to the rapid development of modern industry and the increase of urban population, domestic water and industrial water have increased sharply. my country's fresh water resources are already in short supply. If urban domestic sewage is discharged without treatment, the shortage of water resources will be exacerbated, and there may be irreversible consequences. Therefore, the utilization of domestic sewage treatment equipment is imminent. Domestic sewage treatment equipment will also play an important role in escorting urban development; generally speaking, urban sewage is discharged through underground pipelines, but the process of building underground pipelines will inevitably cause damage to the ecological environment along the way, such as construction The underground pipeline needs to dig throug...
