Foreign material separation equipment for sewage treatment

Abstract

The invention discloses foreign material separation equipment for sewage treatment. The equipment comprises a separator cartridge, the top of which is provided with a feed hopper. A centrifuging device, an annular floatboard, a utility room and a secondary filter unit are successively arranged from top to bottom inside the separator cartridge. The sidewall of the separator cartridge is provided with a water outlet pipe, an exhaust pipe and a heating device. After the centrifuging device pumps sewage and sludge into a rotating cylinder through a sludge pump, the rotating cylinder is driven by arotary driving mechanism to drive sewage and foreign materials therein to rotate. Under the action of centrifugal force, sewage is thrown out of the rotating cylinder and foreign materials slowly falls down into a foreign material drawer under the action of an inclined guide plate. It is convenient and fast to clean up foreign materials in the foreign material drawer, and the secondary filter unit can perform secondary filtration on sludge and sewage, thereby more quickly separating sludge in the sewage. With the heating device and the exhaust device, toxic gases in the sewage are effectivelydischarged. The equipment of the invention has a simple structure and is low-cost.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a kind of debris separation equipment for sewage treatment. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic a...

AI Technical Summary

Problems solved by technology

[0006] Most of the current domestic sewage treatment equipment is only treated by a single filter. However, in the process of sewage discharge, it is difficult to separate and remove the debris. Not only does multiple filtration treatments reduce the filtration and purification speed, but also The large volume is easy to block the pipe or filter screen, so the effect of sewage discharge is not good. The existing debris separation equipment has complex structure and high cost
