Secondary sedimentation tank cleaning device and cleaning method thereof

Abstract

The invention relates to a secondary sedimentation tank cleaning device and a cleaning method thereof. The cleaning device comprises a rack, a base plate, a sliding plate and a pressing plate, whereinthe top of the rack is fixedly connected with the bottom of a rotating bridge; the base plate is fixedly connected with the bottom of the rack; the sliding plate is parallel to the base plate and isarranged on one side of the base plate; a lifting device is arranged on one side of the base plate; the lifting device is capable of driving the sliding plate to move in a vertical direction; the pressing plate is perpendicular to the sliding plate and is rotationally connected with one side of the sliding plate; a driving device for driving the pressing plate to swing is arranged on one side of the sliding plate; the driving device is also capable of holding the pressing plate which is folded to work in a working position; and a cleaning device for cleaning side walls of a secondary sedimentation tank is arranged on one side of the pressing plate. The invention further relates to a cleaning device of the device. The side walls of the secondary sedimentation tank can be automatically cleaned without product halt, no chemical agent is used, the cleaning device is applicable to secondary sedimentation tanks of different sizes, the pressing plate can be propped by the driving device whencleaning is implemented, then a sufficient cleaning intensity can be ensured, the cleaning effect can be ensured, and the cleaning device can be withdrawn after cleaning is completed.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a secondary sedimentation tank cleaning device and a cleaning method thereof. Background technique [0002] The treatment of urban sewage is a complex process with multiple processes. The content of particulate matter in urban sewage is high, such as sediment, metal particles, non-metallic particles, etc. These particles will cause water or environmental pollution and need to be removed. Usually, in the process of sewage treatment, there will be a special process for removing particulate matter, and the process of removing particulate matter in sewage is generally carried out using a secondary sedimentation tank. [0003] The use environment of the secondary settling tank is humid, and urban sewage is conducive to the growth of plants such as moss. Therefore, after long-term use, the wall of the secondary settling tank will be covered with moss, which seriously affects the appeara...

Problems solved by technology

[0003] The use environment of the secondary settling tank is humid, and urban sewage is conducive to the growth of plants such as moss. Therefore, after long-term use, the wall of the secondary settling tank will be covered with moss, which seriously affects the appearance and the water quality of the effluent.

The way of manual cleaning has a great impact on the normal production plan

Adding chemical agents is mainly to add copper sulfate, but this method is costly, and the addition of copper sulfate changes the water quality, which will affect the subsequent treatment process
