Description

Technical Field

[0001] The invention relates to the field of sewage treatment equipment, and in particular to a reciprocating vehicle-type bottom mud discharge equipment for discharging underwater bottom mud in a pool body. Background Art

[0002] With the rapid development of social economy, people's awareness of environmental protection is constantly improving. Various wastewater treatment processes and facilities are constantly being innovated, especially various activated sludge treatment methods are developing rapidly. At the end of the treatment process, sedimentation is generally used to separate the biological sludge and the treated water into solids and liquids. In actual operation, residual sludge often settles to the bottom of the clear water tank in the effluent area. Long-term accumulation will cause anaerobic reaction of the sludge, generate bubbles, cause the sludge to float, and cause secondary pollution of the water body, which eventually leads to excessive effluent water quality.

[0003] At present, the above problems are generally solved by emptying the pool body for cleaning, or by laying a mesh perforated pipe at the bottom and using a sludge pump for external discharge. When the cleaning method is adopted, the entire system needs to be shut down to empty the water in the pool body, which is time-consuming and labor-intensive, and delays production. When the sludge discharge pipe network is laid, there are often blind spots, and the sludge discharge will be uneven due to the different distances of the pipe network. At the same time, a high-power sludge discharge pump is required to achieve this, resulting in energy waste. In addition, the high power causes an increase in the amount of discharged water, which affects the amount of water discharged. Summary of the invention
