Method and device for efficiently and automatically cleaning accumulated sludge on inclined plate (pipe) of high-density precipitation pool

Abstract

The invention discloses a method and a device for efficiently and automatically cleaning the accumulated sludge on the inclined plate (pipe) of a high-density precipitation pool. The automatic cleaning device comprises a medium-high pressure small-flow pump and at least two sets of flushing pipelines, wherein each set of the flushing pipelines comprise a plurality of branch pipes and a main pipe,holes are formed in the branch pipes at a certain interval, the branch pipes are respectively connected to the main pipe, the main pipe of each set of the flushing pipelines is connected to the flow pump, and the set of the flushing pipelines are arranged above the inclined plate / pipe in a high-density precipitation pool. According to the invention, the device is arranged in two or more high-density precipitation pools, and the water in one high-density precipitation pool is pumped through the branch pipes to automatically flush the inclined plate / pipe in other high-density precipitation pools; with the device and the method, the inclined plate of the precipitation pool can be automatically cleaned, so that the complicated work of production stopping, manual and regular cleaning of the inclined plate and the like is reduced or avoided; and the flushing water comes from the high-density precipitation pool, so that the water resource is saved, the waste is reduced, and the new thought isprovided for cleaning the inclined plate of the high-density precipitation pool.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and relates to a method and a device capable of efficiently and automatically cleaning inclined plates / pipes of high-density sedimentation tanks. Background technique [0002] The high-density sedimentation tank was invented by the French company Delimont. Because of its good treatment effect, small footprint and ability to remove phosphate and suspended solids at the same time, it has been widely used in my country's municipal and industrial sewage treatment industries. [0003] However, during the long-term operation of high-density sedimentation tanks, many problems will occur, including fouling of inclined plates or pipes in sedimentation tanks, and algae reproduction. At present, most sewage treatment plants in China generally use high-pressure tap water or reclaimed water after shutting down or semi-stopping production to manually flush the inclined plates (pipes). This kind of cleaning met...

AI Technical Summary

Problems solved by technology

This kind of cleaning method will not only affect the quality of the effluent water due to the shutdown or semi-stop production of the high-density sedimentation tank, but also consume manpower, tap water or reclaimed water, and the economy is poor
