Municipal sewage treatment equipment

Abstract

The invention discloses municipal sewage treatment equipment, which comprises a precipitation device, a flocculation filtering device and an ultraviolet sterilization device which are connected through pipelines, wherein the precipitation device is a box body; a cleaning opening is formed in one side of the box body; a sediment treatment device is arranged on the other side of the box body; the flocculation filtering device comprises a first sealing cover and a first steel barrel; a filtering device is welded on the inner wall of the first steel barrel; the output end of a pressure pump is connected with the first steel barrel; the output end of a dosing pump is connected with the first steel barrel; the ultraviolet sterilization device comprises a second steel barrel and a water outlet; awater outlet is formed in one side of the second steel drum; the ultraviolet sterilization device is arranged at the upper end in the second steel barrel; the ultraviolet sterilization device is connected with an electric control device; a water level monitoring device is arranged below an ultraviolet lamp device; and a stirring device is arranged at the bottom of the second steel barrel. The sewage treatment equipment is used for carrying out sedimentation treatment, flocculation filtration treatment and sterilization treatment on sewage; meanwhile, sediments are convenient to discharge, andthe sewage can be rapidly purified.

Description

technical field [0001] The invention mainly relates to the technical field of sewage treatment, in particular to urban sewage treatment equipment and urban sewage. Background technique [0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within urban areas. Urban sewage contains a large amount of organic matter, germs, and viruses. Due to the high development of industry, the proportion of industrial wastewater has increased year by year, and urban wastewater has become difficult to treat. Direct discharge of wastewater into water bodies will pollute the environment, so urban sewage treatment equipment is required to treat it so that it meets the discharge standard and then discharged into nature. Traditional sewage treatment equipment usually includes sedimentation devices, but the sediment at the bottom is difficult to handle and affects treatment efficiency. Therefore need to invent a kind of high-efficiency sewage treatment equipment t...

[0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within urban areas. Urban sewage contains a large amount of organic matter, germs, and viruses. Due to the high development of industry, the proportion of industrial wastewater has increased year by year, and urban wastewater has become difficult to treat. Direct discharge of wastewater into water bodies will pollute the environment, so urban sewage treatment equipment is required to treat it so that it meets the discharge standard and then discharged into nature. Traditional sewage treatment equipment usually includes sedimentation devices, but the sediment at the bottom is difficult to handle and affects treatment efficiency. Therefore, it is necessary to invent a high-efficiency sewage treatment equipment that can automatically clean the sludge at the bottom of the sedimentation tank, and can fully purify the water quality many times.
