Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an energy-saving car washing machine sewage recycling device. Background Art

[0002] When the transport vehicles of the coal shed of the coking plant are washed by the car washing machine, the coal slime and a large amount of washing water are combined together, and it takes a certain amount of time to settle. However, the volume of car washing on site is large, and the sedimentation tank is generally not set too large due to the limited site area. The size of the sedimentation tank cannot meet the coal slime sedimentation effect, and cannot meet the vehicle washing requirements, and the washing water of the car washing cannot be recycled. If the use requirements are to be met, the sedimentation tank needs to be set larger, which will increase the area occupied by the sedimentation tank.

[0003] After multiple stages of sedimentation, there will be a lot of precipitated coal slime in the sedimentation tank. At present, a sewage pump is generally set up on site. It is necessary to start the sewage pump within a week to replace the coal slime water in each level of sedimentation tanks into the raw material greenhouse, which consumes about 30 tons of water. This wastes water resources too much and will cause manual removal of coal slime, which takes about 7 days. This increases the workload of on-site workers. When the coal slime is removed manually, vehicles cannot pass, and vehicles cannot be effectively cleaned when cleaning the sedimentation tank, which also brings more inconvenience to on-site management.
