Automatic cleaning device for sewage treatment plant floating-flow type secondary sedimentation tank effluent weir

Abstract

The invention discloses an automatic cleaning device for a sewage treatment plant floating-flow type secondary sedimentation tank effluent weir. The device is characterized in that a machine shell isfixedly installed on a sliding table, a first ultraviolet lamp tube is fixedly mounted in a mounting hole, close to the right side surface, in the machine shell, a rear flushing spray head is fixedlymounted in a mounting hole in the rear side surface of the machine shell, a front rotating arm is arranged on the machine shell, a front brush motor is mounted on the front rotating arm, a front brushis mounted on the output shaft of the front brush motor, a rear rotating arm is arranged on the machine shell, a rear brush motor is installed on the rear rotating arm, a rear brush is installed on the output shaft of the rear brush motor, a front flushing spray head is installed in an installation hole in the front side surface of the machine shell, a second ultraviolet lamp tube is fixedly installed in an installation hole, close to the left side surface, in the machine shell, and the two ends of a third ultraviolet lamp tube are installed on the front side surface and the rear side surfacein the machine shell respectively. The automatic cleaning device is simple in structure, high in cleaning efficiency and good in cleaning effect, and greatly reduces the labor intensity of operators.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an automatic cleaning device for an outlet weir of a floating-flow secondary settling tank in a sewage treatment plant. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or 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. The secondary settling tank is an important part of the activated sludge system. Its main function is to separate the sludge, clarify the mixed solution, concentrate and return the activated sludge. Its working effect can directly affect the effluent water quality and return sludge concentration of the acti...

Problems solved by technology

The growth of moss in the effluent weir of the secondary sedimentation tank directly affects the operation of the sewage treatment system. How to effectively remove the interference of moss on the effluent water quality is a technical problem that plagues sewage treatment plants.

Most of the moss begins to grow in spring, and it adheres to the pool wall like hair in the early stage, and the color is dark green; the temperature gradually becomes suitable, and it begins to proliferate and suspend in the water a...
