Description

Pulse water distribution device

Technical Field

The utility model belongs to the sewage treatment device field, in particular to pulse water distribution device.

Background

The sewage treatment problem is inevitably brought by the development of life, cities and industry, in the sewage treatment process, the sewage needs to be treated by an anaerobic tank, and under the anaerobic condition, the anaerobic microorganisms convert long-chain hydrocarbon macromolecular organic matters into methane and carbon dioxide. In order to improve the treatment effect of the anaerobic tank, the wastewater needs to be uniformly discharged into the biochemical treatment anaerobic tank. In the prior art, the pulse of intermittent water feeding is adopted to generate a better muddy effect, and the pulse tank plays a role of intermittent water feeding.

Pulse cans are generally of three types, vacuum, slit-door and siphon, according to their operating principle. Although the vacuum type pulse water distributor can flexibly adjust the pulse period, a more complex vacuum device needs to be installed in the construction process, and the noise is large during working; the gate-cutting type water distributor is characterized in that an annular cutting gate is arranged on a central water inlet pipe, the cutting gate is opened and closed through a pulse valve, the pulse period is controlled through the water level lifting time, but the pulse valve is difficult to process, and the pulser fails due to mud accumulation and the like. The siphon water distributor is mainly of bell jar siphon type and comprises: the siphon-breaking device comprises a water inlet chamber, a bell jar, a siphon-breaking cylinder, a downpipe and the like, wherein a siphon-breaking hole is arranged in a low water level area of the wall of the bell jar. Siphon-type water-locator sets up in the water distribution pond top in sewage treatment pond, and its theory of operation is: the water enters the water inlet chamber through the water inlet pipeline, the water level in the water inlet chamber and the bell jar gradually rises, when the water level exceeds the top of the downpipe (namely, the high water level), part of water overflows into the downpipe, and the air in the bell jar is gradually taken away in the overflow process to form the siphon effect. At this time, the water in the water inlet chamber rapidly enters the sewage treatment tank through the bell jar and the downpipe. When the water level in the water inlet chamber is reduced to a siphon destroying hole (namely low water level) on the siphon destroying cylinder, air enters the bell jar along the siphon destroying cylinder to destroy the siphon effect, the water level of the water inlet chamber is raised again, and the circulation forms periodic water flow pulse. The pulse period and pulse flow rate are controlled by the time the siphon effect occurs and is destroyed.

When the water inflow of the common pulse tank is too small, pulse water distribution may not occur, and the adaptability to water quantity change is poor. Intermittent water inlet can be realized by pulse water outlet, but the stirring effect is limited, and sewage cannot uniformly enter the treatment tank.
