Pulse water distribution device capable of being adjusted according to water yield

Abstract

The invention provides a pulse water distribution device capable of being adjusted according to water yield. The pulse water distribution device is arranged above a biochemical pool; the pulse water distribution device comprises a generator chamber, a central siphon and a communicating pipe; the upper end of the central siphon is arranged in the generator chamber; the lower end of the central siphon is arranged in a central vertical shaft of the biochemical pool; a bell jar and two clapboards are arranged in the generator chamber; the generator chamber is divided into three grids by the clapboards, namely a central chamber at the middle, and a left side chamber and a right side chamber distributed on the two sides of the central chamber. The bell jar is arranged above the top end of the central siphon, the central chamber of the generator chamber is communicated with the left side chamber or the right side chamber through pipe openings in the two ends of the communicating pipe, a pneumatic adjusting butterfly valve is arranged on the communicating pipe, and an exhaust pipe and a water inlet pipe are mounted outside the generator chamber. The adjustable pulse water distribution device provided by the invention can ensure that the pulse period is not changed, so that the effluent of the pretreatment system is stable, and the subsequent biochemical treatment effect is ensured.

Description

technical field [0001] The invention relates to the field of water treatment process equipment, in particular to a pulse water distribution device which can be adjusted according to the water output. Background technique [0002] The pulse water distributor uses the fast-flowing water flow in the siphon to take away the air in the main pipe, so that a certain degree of vacuum is formed in the main pipe. Under the action of the atmospheric pressure inside and outside the pipe, the water in the container enters the main pipe and is discharged into the pool. The water flow speed is fast, and the water distribution can be completed in a short time, achieving the effect of pulse, stirring up the sludge at the bottom of the pool, so that it is continuously and fully mixed with the sewage in the pool, and the anaerobic bacteria and the organic matter in the sewage are fully contacted and reacted. The pulse water distributor is mainly used in the anaerobic hydrolysis process, using ...

AI Technical Summary

Problems solved by technology

When the influent flow rate is unstable, because the volume of the water reservoir of the existing pulse water distribution device is not variable, the pulse period changes with the change of the influent flow rate, resulting in excessive water output in pre-treatment systems such as anaerobic tanks and hydrolytic acidification tanks. Small or too large, it will bring impact load to the subsequent aerobic treatment system and affect the water outlet effect
